Chronic Fatigue Syndrome details

Zinc supplementation may benefit CFS

Maes M, Mihaylova I, De Ruyter M. Lower serum zinc in Chronic Fatigue Syndrome (CFS): relationships to immune dysfunctions and relevance for the oxidative stress status in CFS. J Affect Disord. 2006;90:141.

We explored the relationship between serum zinc levels and chronic fatigue syndrome (CFS) in a study that compared patients with CFS to normal volunteers. By using an atomic absorption method, we measured serum zinc concentrations and found that those suffering from CFS had significantly lower levels of zinc compared to healthy individuals.

Interestingly, we observed a trend indicating that lower zinc levels correlated with greater CFS severity. Patients also reported a negative correlation between their zinc levels and their subjective experiences of infection. This suggests that zinc plays a role in the immune dysfunction commonly seen in CFS.

Furthermore, we noted that lower serum zinc was associated with higher levels of inflammatory markers and certain defects in the early activation of T cells. Since zinc acts as a potent antioxidant, our findings indicate that CFS is linked to increased oxidative stress in these patients. Given this, it may be beneficial for some CFS patients to consider zinc supplements as part of their treatment approach.

Zinc's mixed impact on ear infections

Abba K, Gulani A, Sachdev HS. Zinc supplements for preventing otitis media. Cochrane Database Syst Rev. 2010. doi:10.1002/14651858.CD006639.pub2

We explored whether zinc supplements could help prevent otitis media, which is a common ear infection affecting many, especially young children. Our examination included several randomized, placebo-controlled trials where participants received zinc supplements at least once a week for a minimum of a month.

In total, we identified 12 trials, but only 10 provided sufficient data for analysis. Among healthy children from low-income communities, most studies did not show a clear benefit of zinc on reducing ear infections. However, one trial with over 1600 participants did find a significantly lower incidence of otitis media in those taking zinc, suggesting that it might help. Additionally, a small study focusing on infants with severe malnutrition hinted at potential benefits, yet it is important to note this was based on limited data.

Overall, the evidence isn't definitive—while some results point towards positive effects, particularly in specific groups, many trials did not support the effectiveness of zinc in healthy children. Furthermore, zinc supplements appeared safe, with minimal reports of adverse effects.

Zinc's complex role in prostate cancer

Ghimire K, Awasthi BP, Yadav K, Lee J, Kim H, et al. Prostate cancer-selective anticancer action of an oxindole derivative via HO-1-mediated disruption of metabolic reprogramming. Chem Biol Interact. 2025;408:111393. doi:10.1016/j.cbi.2025.111393

We explored the relationship between zinc levels and prostate cancer treatments, particularly focusing on a novel compound known as 3D. This compound showed a strong potential to target prostate cancer cells, contributing to a decrease in their proliferation rates.

Our analysis revealed that compound 3D selectively impacted key metabolic processes in prostate cancer cells by suppressing factors related to energy production, such as lactate levels. Interestingly, it also reduced the activity of transporters involved in zinc absorption while leaving those responsible for zinc export untouched.

We also found that the effectiveness of 3D could be reversed with zinc treatment, highlighting a complicated interaction between zinc and this therapeutic approach. While the compound successfully lowered zinc levels in cells and inhibited cancer growth, it is essential to note that we did not find significant benefits from zinc treatment by itself in the context of this study.

Overall, our findings suggest that targeting zinc metabolism and enhancing heme oxygenase-1 expression could be a promising strategy in prostate cancer therapy, more so than the direct application of zinc itself. The results illustrate the potential for combining innovative small molecules with an understanding of cancer metabolism in the development of treatment strategies.

We aimed to uncover the connection between dietary zinc deficiency and symptoms associated with major depressive disorder (MDD). In our study, we used rats fed either a zinc-adequate diet or one deficient in zinc for four weeks.

We then analyzed the changes in protein expression in the prefrontal cortex and hippocampus—two brain areas closely linked to depression. This approach allowed us to see how zinc deficiency impacts the brain at a molecular level.

Our findings revealed that significant alterations occurred in proteins related to zinc transport and mitochondrial function due to the deficiency. In particular, we saw a notable decline in the activity of complex I of the mitochondrial energy production pathway in the prefrontal cortex.

These results suggest that low zinc levels can disrupt vital brain functions, potentially contributing to the development of depressive symptoms. This highlights the importance of maintaining adequate zinc levels for mental health.

We investigated how zinc supplementation impacts chronic gastritis, particularly in the context of oxidative stress and inflammation. By establishing models of inflammatory injury in C57BL/6 mice, we were able to analyze the effects of zinc on the gastric mucosa, which is crucial for maintaining digestive health.

Our findings revealed that when the mice were exposed to a compound known to induce inflammation, there was a noticeable rise in reactive oxygen species (ROS), signaling an increase in oxidative stress. This stress resulted in an uptick in certain harmful factors related to inflammation and cell death. However, when we introduced zinc as a supplement, it effectively reduced these damaging factors, alleviating inflammation and the resulting cell death in both the mouse stomach and cultured cells.

Overall, our study indicates that zinc supplementation can play a significant role in controlling inflammation and protecting against cellular damage caused by oxidative stress in chronic gastritis. By modulating the ROS/NF-κB signaling pathway, zinc demonstrates potential as a protective agent for gastric health.

Zinc intake may reduce IBS risk

Zhuang Y, Li L, Ran Y, Zhang Y, Chen J, et al. Dietary copper, zinc, copper/zinc ratio intakes and irritable bowel syndrome risk: a large-scale prospective cohort study from UK Biobank. Am J Epidemiol. 2024. doi:10.1093/aje/kwae412

We explored the potential connection between dietary zinc intake and the risk of developing irritable bowel syndrome (IBS) through a large-scale analysis of participants from the UK Biobank. By assessing the dietary habits of 175,421 individuals who did not have IBS at the start of the study, we sought to understand how various levels of zinc, as well as copper and their ratio, might influence the onset of this troublesome condition.

Over an average follow-up period of 13.3 years, we observed that 2,240 participants were diagnosed with new-onset IBS. Notably, our findings revealed a U-shaped relationship between zinc intake and IBS incidence. For those consuming less than 10 mg of zinc per day, an increase in intake was linked to a decreased risk of IBS. Specifically, individuals taking less than 10 mg of zinc daily experienced a reduced risk with higher zinc consumption.

However, the relationship shifted for individuals who had higher intakes of copper and zinc; no significant benefits were noted when intakes reached or exceeded established thresholds. This suggests that there's a delicate balance to maintain when it comes to zinc and copper in the diet.

Importantly, subgroup analysis indicated that younger individuals, particularly those under 60, could benefit more from slight increases in zinc. Overall, our study highlights the significance of dietary management, emphasizing that reasonable zinc intake may contribute to lowering IBS risk while keeping copper and the copper/zinc ratio in a sensible range.

Sarkar T, Mandal T. Preoperative oral zinc tablet decreases incidence of postoperative sore throat. Indian J Anaesth. 2020;64:409. doi:10.4103/ija.IJA_959_19

We investigated the impact of dispersible zinc tablets on postoperative sore throat (POST) experienced by patients after endotracheal intubation. In our study, 88 patients were divided into two groups. One group received a 40 mg zinc tablet, while the other received a placebo 30 minutes before their surgery.

Our findings revealed that the zinc group reported significantly fewer instances of POST at the 4-hour mark compared to the placebo group. Specifically, only 6.8% of patients in the zinc group experienced POST, while a higher 31.8% in the placebo group did. Furthermore, none of the patients taking zinc reported severe sore throat, a stark contrast to three patients in the placebo group who did.

Additionally, we noted lower severity ratings for sore throat in the zinc group at various time intervals post-surgery. The results emphasize that taking zinc tablets before surgery can effectively mitigate the incidence and discomfort of sore throat following intubation, presenting a simple solution for a common postoperative issue.

We investigated how intranasal zinc (Zn) treatment affects symptoms of allergic rhinitis (AR), specifically focusing on individuals suffering from Japanese cedar pollinosis (JCP), a common seasonal allergy. In our study, we monitored 57 control subjects and 44 patients from preseason through the allergy season, observing the levels of Zn in both nasal fluid and serum.

Our findings showed that after exposure to pollen, the level of zinc in the nasal lining fluid of JCP patients significantly increased, while their serum zinc levels notably decreased compared to the control group during the JCP season. To delve deeper, we used model mice that could mimic these changes and the allergy symptoms of the patients.

The results from this mouse study were promising. We observed that treating these mice with a dose of zinc, similar to what humans might use, led to a notable improvement in their allergy symptoms. Additionally, the number of mucin-secreting goblet cells, which indicate a response to allergies, significantly decreased following the zinc treatment.

Our study points towards the potential of using intranasal zinc as a way to alleviate allergy symptoms, suggesting a new approach to managing allergic rhinitis.

We explored how a carboxylated zinc compound, known as Zn-phthalocyanine (ZnPc), impacts Alzheimer’s disease by examining its effects on amyloid beta (Aβ) deposition in a specific mouse model. Over a 12-week period, we administered weekly injections of ZnPc to older J20 mice, carefully assessing their cognitive abilities through various behavioral tests. Early findings showed that this zinc-based treatment significantly improved learning and memory in these mice.

We found that ZnPc accumulated in the brain and effectively reduced levels of Aβ both within neurons and in surrounding areas. Notably, neuronal health appeared to improve as more neurons were observed in regions of the brain crucial for memory, like the cortex and hippocampus. The treatment also reduced harmful inflammatory responses, as indicated by fewer activated astrocytes and microglia, which are often involved in neurodegeneration.

Furthermore, improvements were noted in blood vessel integrity and overall brain structure, suggesting that ZnPc not only targets Aβ but also supports broader neurological health. In summary, our results propose that ZnPc may serve as a promising therapeutic agent for Alzheimer’s disease, emphasizing the potential of zinc and its compounds in addressing neurodegenerative issues.

We explored how zinc affects blood clotting, particularly through a substance called Zn@SiO nanocomposite. This material shows promise as a hemostatic agent, which means it helps stop bleeding by promoting the formation of stable blood clots.

During our analysis, we examined various aspects of how this nanocomposite interacts with blood. It activates specific factors in the coagulation cascade—the process our bodies use to form clots. With the presence of zinc in the material, we observed enhanced activation of these factors, leading to improved clot formation.

Our research involved synthesizing and characterizing the Zn@SiO nanocomposite using several methods, including XRD, FTIR, and HRTEM. We also tested its effects on red blood cell aggregation, platelet adhesion, and several vital clotting time measures. The results indicate that Zn@SiO has significant hemostatic properties, showing potential for use in surgeries and trauma care.

This study highlights the exciting role of zinc in optimizing hemostasis, making it a candidate worth considering for medical applications related to bleeding management.

We explored the connection between essential trace elements, particularly zinc, and Hashimoto’s thyroiditis (HT) in women who were newly diagnosed. In this study, we looked at a group of 56 women with HT and compared them to 64 matched controls.

The results showed that women with HT had significantly lower levels of selenium, iron, and zinc in their blood compared to the controls. Interestingly, their copper levels were higher. We examined the relationships between these trace elements and thyroid autoantibodies, which can indicate the presence of autoimmune activity affecting the thyroid.

While we noted a significant correlation between lower zinc (and other elements) and higher levels of thyroid antibodies, the study did not specifically focus on zinc treatment. This means that while zinc levels appear to be linked to autoantibody levels in HT, we can't definitively state that zinc treatment will improve the condition without further dedicated research.

Overall, the study indicates that lower zinc levels in conjunction with selenium and iron deficiencies might be involved in the autoimmune response seen in Hashimoto’s thyroiditis. Thus, this provides an avenue for future exploration into zinc's role as a potential supplement for women diagnosed with this condition.

This study was designed as a randomized double-blind, placebo-controlled trial to examine how zinc gluconate supplementation might alleviate migraine symptoms in adult women. We followed 60 women, averaging about 35 years old, who either received 15 mg of zinc per day or a placebo for a duration of 12 weeks.

Over the trial, we observed significant improvements in those taking zinc. The frequency of migraine attacks, as well as the duration and severity of the headaches, drastically decreased for participants receiving zinc. We used various assessments, such as a numerical rating scale and the Migraine Disability Assessment test, to evaluate these changes.

Additionally, zinc supplementation showed a notable reduction in levels of low-density lipoprotein (LDL) cholesterol and high-sensitivity C-reactive protein (hs-CRP), both of which are associated with inflammation. However, no significant changes in triglycerides or high-density lipoprotein (HDL) levels were seen. After taking initial values into account, the changes in lipid levels and hs-CRP weren’t significant.

Overall, we found that zinc supplementation can beneficially impact migraine symptoms, reducing their severity and frequency among women. This offers a promising direction for migraine management without the side effects often associated with traditional medications.

We explored how zinc levels impact cancer cells and immune function, particularly focusing on macrophages, which are crucial for our body’s defense against tumors. Our research revealed that cancer cells often have decreased expression of specific genes tied to immune response, and this links to resistance against therapies designed to unblock immune checkpoints.

By upregulating a zinc importer known as SLC39A9, these cancer cells manage to hoard zinc for themselves, leaving the surrounding tumor microenvironment (TME) depleted of this vital nutrient. This competition for zinc results in macrophages becoming zinc-starved, which diminishes their ability to perform essential tasks like engulfing and destroying cancer cells.

Interestingly, we found that when we replenished zinc levels in the TME—through a dietary intervention—these macrophages could regain their pro-phagocytic function. This change significantly improved the response of certain tumors to immunotherapy treatments. Notably, T cells weren’t required for this transformation, indicating that macrophages alone play a pivotal role.

Our results are clinically relevant, showing that cancer patients with reduced zinc levels in their body tend to experience worse outcomes. Overall, we identified a new mechanism by which cancer cells can disrupt immune function, highlighting zinc’s critical role in both tumor environments and immunotherapy effectiveness.

Zinc cream alleviates cold sores

Based on 9 Researches

Godfrey HR, Godfrey NJ, Godfrey JC, Riley D. A randomized clinical trial on the treatment of oral herpes with topical zinc oxide/glycine. Altern Ther Health Med. 2001;7:49.

We conducted a double-blind, placebo-controlled clinical trial to explore the effectiveness of a zinc oxide/glycine cream in treating cold sores caused by facial and circumoral herpes. By dividing 46 participants into two groups, one receiving the zinc treatment and the other a placebo, we aimed to measure how this formulation affected the duration and severity of cold sore symptoms.

Our results were quite promising! Participants who began using the zinc oxide/glycine cream within the first 24 hours of noticing symptoms experienced cold sore lesions that lasted only an average of 5 days, compared to 6.5 days for those on the placebo. Additionally, we noticed a significant reduction in the overall severity of their symptoms, including blistering, soreness, itching, and tingling.

As for side effects, subjects treated with the zinc cream experienced only minor and reversible issues typical of ionic zinc salt solutions. This indicates that the zinc oxide/glycine cream is not only effective but also safe for treating cold sores, presenting a valuable option for many people seeking relief from this common condition.

Common Cold details

Zinc shortens cold duration variability

We explored how zinc lozenges affect the duration of the common cold through a detailed analysis of multiple trials. In particular, we focused on the Mossad (1996) trial involving zinc gluconate lozenges, which revealed an average reduction of cold duration by about 4.0 days. While that sounds promising, our findings through a quantile treatment effect (QTE) analysis tell a more nuanced story.

Interestingly, the QTE analysis showed that for individuals suffering from lengthy colds lasting 15 to 17 days, the zinc lozenges could shorten their illness by as much as 8 days. On the flip side, those with shorter, 2-day colds only experienced a 1-day reduction in sickness. This suggests that while zinc may help, its effectiveness varies significantly depending on the initial duration of the cold, making the overall average effect less informative than we might think.

Our examination extended to three trials that used zinc acetate lozenges, yielding a similar average reduction of around 2.7 days. However, again, those averages concealed varying effects for short and long colds, highlighting the importance of looking beyond simple averages in treatment studies.

Overall, we observed that zinc lozenges can indeed help with cold duration, but the extent of that help is very much dependent on how long a person has been suffering. This approach to understanding treatment effects through QTE analysis could have important implications not just for cold treatment but also for analyzing other health outcomes.

Zinc alleviates diabetic muscle atrophy

Yu X, Chen X, Wu W, Tang H, Su Y, et al. Zinc Alleviates Diabetic Muscle Atrophy via Modulation of the SIRT1/FoxO1 Autophagy Pathway Through GPR39. J Cachexia Sarcopenia Muscle. 2025;16:e13771. doi:10.1002/jcsm.13771

Our investigation aimed to understand how zinc affects muscle atrophy in diabetes, a serious complication that leads to muscle loss. Using diabetes-induced mice, we treated them with zinc sulfate for six weeks and observed notable improvements in their muscle condition.

We conducted various analyses to evaluate the impact of zinc on autophagy—the process that helps manage muscle mass. The results were promising; zinc appeared to enhance muscle recovery by regulating specific molecular pathways connected to muscle health.

Additionally, our in vitro studies with diabetic muscle cells revealed similar results, with zinc supplementation proving beneficial in reducing excessive autophagy. Overall, this suggests that incorporating zinc into treatment plans could be a promising approach to counteract muscle deterioration in diabetic patients.

Eczema details

Zinc enhances eczema recovery

Crisóstomo M, Santos MC, Tavares E, Cunha F. Transient symptomatic zinc deficiency in an exclusively breastfed infant. BMJ Case Rep. 2021;14. doi:10.1136/bcr-2021-241754

We investigated the relationship between zinc deficiency and eczema in a 3-month-old infant who was exclusively breastfed. The infant presented with symptoms like scaling erythematous dermatitis affecting her face and other areas, alongside irritability and poor weight gain. Her mother had been taking isoniazid for tuberculosis during pregnancy, which possibly contributed to the infant’s zinc deficiency.

After initial treatments for a suspected skin infection didn’t bring any changes, we found that the baby had low serum zinc levels and low zinc concentration in her breast milk. This led us to believe the skin condition was due to zinc deficiency rather than an infection. We started zinc supplementation, and the infant showed remarkable improvement in her skin condition and weight.

By 6 months, the infant had begun eating solid food, and we stopped the zinc supplements, with no signs of eczema returning. This case underscores the importance of monitoring zinc levels in breastfed infants, especially when mothers are on specific medications that might impact nutrient transfer through breast milk.

Rosacea details

Zinc penetrates skin in rosacea

Ahn HJ, Shin MK. Zinc penetration through the skin barrier in atopic dermatitis and rosacea using reflectance confocal microscopy. Exp Dermatol. 2024;33:e14971. doi:10.1111/exd.14971

We investigated how well zinc penetrates the skin in individuals with rosacea, a common condition that affects skin barrier function. Using a non-invasive technique called reflectance confocal microscopy, we compared the skin barrier permeability between those with rosacea, atopic dermatitis, and healthy individuals.

Our results revealed that zinc penetration was greater in patients with rosacea compared to those with healthy skin. Specifically, we observed higher intensity readings of zinc at a depth of 8 micrometers in the skin of rosacea patients. This indicates that their skin barrier might be more compromised in the upper layers.

Interestingly, when comparing both conditions, we found that patients with atopic dermatitis showed greater zinc penetration at deeper layers of the skin. This suggests subtle differences in how these two conditions affect skin barriers. Overall, the findings suggest that patients with rosacea experience increased permeability in the upper layers of the skin due to weakened barrier function.

Dietary zinc status is associated with ZnT3 (SLC30A3), IL-6 gene expressions and spinal cord tissue damage in spinal cord tissue in a cuprizone-induced rat Multiple Sclerosis model. J Trace Elem Med Biol. 2024;86:127540. doi:10.1016/j.jtemb.2024.127540

We explored how dietary zinc levels influence spinal cord damage and gene expressions associated with Multiple Sclerosis (MS) using a cuprizone-induced rat model. The study included 46 adult male Wistar rats divided into five groups, with some receiving zinc supplementation while others followed a zinc-deficient diet.

After eight weeks of treatment, we found that the rats with MS symptoms showed elevated markers of tissue damage and inflammation, particularly in the groups that lacked zinc. Notably, those receiving zinc supplementation exhibited significantly reduced levels of harmful substances, bringing them back closer to control levels.

Our findings highlight zinc's protective effects in a model of MS, suggesting that incorporating zinc into treatment plans could help alleviate some symptoms associated with this autoimmune disorder. This is promising for future treatment strategies for those affected by MS.

Zinc's uncertain role in hypothyroidism

Hypothyroidism details

Nikkhah M, Vafa M, Abiri B, Golgiri F, Sarbakhsh P, et al. The Effect of Some Micronutrients Multi-Supplementation on Thyroid Function, Metabolic Features and Quality of Life in Patients Treating With Levothyroxine and Vitamin D: A Double-blind, Randomized Controlled Trial. Med J Islam Repub Iran. 2024;38:133. doi:10.47176/mjiri.38.133

We conducted a study to investigate the effects of micronutrient supplementation, including zinc, on thyroid function and overall quality of life in patients with hypothyroidism. Our trial involved 104 participants who were receiving levothyroxine and vitamin D. They were randomly assigned to either a group that received a mix of essential nutrients or a placebo group over eight weeks.

We measured various health markers before and after this period, including thyroid hormone levels, cholesterol, insulin resistance, and blood pressure. Our findings suggested that the group receiving the micronutrient supplement experienced improvements in insulin resistance and overall quality of life. However, it’s important to note that the specific effects of zinc alone are somewhat difficult to isolate, as it was part of a combination of nutrients being tested.

Ultimately, while the study indicates potential benefits of micronutrient supplementation for thyroid function in hypothyroid patients, further trials are necessary to clearly define the role of zinc and other nutrients in this context.

Based on 3 Reviews

Bhardwaj A, Swe KMM, Sinha NK. Treatment for osteoporosis in people with beta-thalassaemia. Cochrane Database Syst Rev. 2023;5:CD010429. doi:10.1002/14651858.CD010429.pub3

We explored how zinc supplementation might help with back pain in individuals with beta-thalassaemia. The research included a randomized controlled trial with 42 participants, where some received zinc while others were given a placebo.

Results showed that zinc supplementation likely increased the bone mineral density (BMD) at the lumbar spine and hip after 12 to 18 months of treatment. This improvement in bone health could suggest potential benefits in pain relief, although the study didn’t directly measure back pain outcomes.

Even though the findings about BMD improvements are promising, we should be cautious. The trial didn't provide direct evidence on whether zinc specifically alleviates back pain. It’s essential to recognize that while we observed positive changes in bone density, interpreting this as a definitive solution for back pain would be premature.

Thus, further research is necessary to connect zinc's effects on bone health to actual pain relief in order to offer clearer guidance on its use as a treatment for back pain.

Chronic Cough details

Zinc acetate ineffective for chronic cough treatment

Very Likely Ineffective

Researchers tested whether zinc acetate could help people suffering from persistent, hard-to-treat cough. In this randomized, placebo-controlled pilot study, 34 participants received either zinc acetate or placebo for 6 weeks, with improvements measured using four different cough and quality-of-life scales.

While zinc successfully increased serum zinc levels in treated participants, both groups improved similarly across all measures. The improvements in cough symptoms and quality of life were too small to meet clinically meaningful thresholds, suggesting zinc acetate offers no real advantage over placebo for chronic cough sufferers.

Constipation details

Zinc may mitigate granisetron constipation

Nacci C, Fanelli M, Potenza MA, Leo V, Montagnani M, et al. Carbon monoxide contributes to the constipating effects of granisetron in rat colon. World J Gastroenterol. 2016;22:9333.

We investigated how zinc might play a role in alleviating the constipation effects caused by granisetron, a medication often used to prevent nausea. In the studies, male rats were treated with varying doses of granisetron, alongside zinc protoporphyrin IX (ZnPPIX), to see how these compounds interacted.

Interestingly, while granisetron was found to increase the time to first defecation in the rats, ZnPPIX alone did not have a notable effect on constipation. However, when combined with granisetron, ZnPPIX successfully reversed the constipation induced by this medication. This suggests that zinc, acting through the heme oxygenase/carbon monoxide (HO/CO) pathway, could potentially mitigate constipation.

Nonetheless, it’s crucial to note that ZnPPIX’s effectiveness was only observed when paired with granisetron; its standalone administration didn’t significantly alter gastrointestinal motility. This highlights a specific interaction rather than a general benefit of zinc in treating constipation.

Headache details

Zinc reduces migraine symptoms

We conducted a randomized, double-blind, placebo-controlled trial to explore how zinc gluconate affects migraine symptoms in women. Sixty participants, with an average age of 35, were given either 15 mg of zinc per day or a placebo for 12 weeks, allowing us to measure the impact on headache frequency, duration, and intensity.

The results were quite promising; zinc supplementation significantly reduced how often headaches occurred, shortened their duration, and decreased the severity of the migraines reported. Participants in the zinc group experienced notable improvements, as indicated by their responses to the headache severity scale and a disability assessment questionnaire.

Furthermore, we found that zinc also had a positive effect on certain health markers. The serum levels of low-density lipoprotein (LDL), total cholesterol, and high-sensitivity C-reactive protein (hs-CRP) decreased with zinc supplementation. However, we didn’t observe significant changes in triglycerides or high-density lipoprotein (HDL) levels after adjusting for baseline values.

In conclusion, zinc supplementation appears to hold beneficial effects on migraine severity and frequency, offering a potential alternative for those who seek relief from these debilitating headaches.

We investigated how zinc affects heartburn through the case of a 76-year-old Japanese man who experienced significant discomfort after undergoing a total gastrectomy. For two weeks, he suffered from a sore throat, heartburn, and difficulty swallowing. Endoscopy revealed deep, craterlike ulcers in his esophagus, but tests for viral infections were negative.

After initial treatment, his symptoms returned, prompting further investigation. Eventually, we found that his serum zinc level was low at 38 µg/dL, which led to a diagnosis of zinc deficiency. Following oral zinc supplementation, the patient reported relief from his symptoms and a noticeable improvement in the esophageal ulcers observed during a follow-up endoscopy.

Over the five years since his treatment, the patient has continued to take zinc supplements and has not faced similar issues again. This case suggests that zinc can play a crucial role in treating heartburn issues related to ulcers, especially in those with a deficiency.

We explored how zinc affects acne through a systematic review and meta-analysis that looked at two main questions. First, we wanted to know if there are differences in zinc levels between people with acne and those without. Second, we examined how effective zinc treatments are for managing acne.

Our findings showed that individuals with acne had noticeably lower serum zinc levels compared to those in the control group. Furthermore, when we looked at treatments, those who received zinc showed a significant reduction in their inflammatory papule count—a common symptom of acne. Importantly, we noted that side effects from zinc supplementation were similar to those seen in other treatments, suggesting that zinc is safe to use.

Overall, acne patients appear to benefit from improved zinc levels, especially when zinc is used either on its own or alongside other acne treatments. This gives hope for those looking for effective ways to tackle acne issues!

Anti-pimple is a powerful antioxidant that preserves the youth and beauty of the skin, hair, and nails, and improves visual acuity. It enhances the body's defences by stimulating the production of antibodies and leukocytes, thus supporting stable immunity. Zinc is vital in treating acne and promotes recovery by reducing skin inflammation and combatting bacterial infections. The typical daily intake for adults is 15 mg, while children need between 3 to 12 mg. Notably, zinc can enhance the body's resistance during colds, making it particularly effective at the first sign of illness. In my experience, my children have not missed any classes due to colds for two years. Moreover, I have not experienced herpes outbreaks in three years.

Cardiovascular Disease details

Zinc counters heart cell injury

Guo J, Ma T, Wang B, Xing B, Huang L, et al. Zn protects H9C2 cardiomyocytes by alleviating MAMs-associated apoptosis and calcium signaling dysregulation. Cell Signal. 2025;127:111629. doi:10.1016/j.cellsig.2025.111629

We set out to investigate how zinc might help protect heart cells from damage caused by a lack of blood flow, known as myocardial ischemia-reperfusion injury (MIRI). Using H9C2 cells, which are derived from rat heart tissue, we simulated this injury by depriving these cells of oxygen and then reintroducing it while treating them with zinc.

Through this process, we found that zinc treatment significantly increased cell viability compared to those that did not receive zinc. Cells exposed to ischemia showed typical signs of trauma, like heightened levels of apoptosis—or programmed cell death—and calcium overload, which can further damage cells.

Interestingly, zinc seemed to tackle these issues by lowering the levels of certain proteins related to cell death. It also played a role in regulating calcium levels by interacting with various cellular pathways. In fact, when we silenced specific proteins involved in these pathways, the protective benefits of zinc were even more pronounced.

Our findings suggest that zinc can relieve the harmful effects of ischemia by mitigating cell death and regulating calcium overload, which offers hope for future treatments for heart-related conditions impacted by blood flow interruptions.

We explored how zinc might help in treating and preventing the common cold. The study focused on zinc's effects, isolating it from other treatments to understand its true impact on cold symptoms. By doing this, the researchers aimed to clarify whether zinc could genuinely shorten the duration of a cold or alleviate its symptoms.

The findings were intriguing but showed that zinc might not yield significant benefits for everyone. While some individuals reported a slight reduction in cold symptoms, the evidence did not strongly support zinc as an effective treatment overall.

This means that, for those seeking relief from a nasty cold, zinc alone might not be the go-to solution we hoped it would be. It’s essential to consider this information when deciding on a cold treatment plan and to approach zinc with realistic expectations.

Chest Pain details

Zinc treatment for angina pectoris

Eby GA, Halcomb WW. High-dose zinc to terminate angina pectoris: a review and hypothesis for action by ICAM inhibition. Med Hypotheses. 2006;66:169.

We delved into an intriguing question: Can high doses of zinc help relieve chest pain caused by angina pectoris? Our research reviewed studies that highlight how zinc may play a role in managing this condition. Angina pectoris often results from arteriosclerosis, where the arteries become narrowed due to cholesterol buildup and other factors.

We discovered that patients with severe atherosclerosis showed promising improvements when treated with high-dose zinc. Specifically, a treatment regimen involved raising serum zinc levels significantly, resulting in symptom relief for many individuals. In one notable case, 12 out of 16 patients experienced measurable benefits, including one patient who also suffered from Raynaud's disease.

Furthermore, our analysis noted that long-term exposure to zinc in the environment correlated with reduced incidence of angina and ischemic events during exercise. Zinc appears to possess antioxidant properties, which may protect against the oxidation of LDL cholesterol, a key player in artery damage. By blocking certain inflammatory factors and promoting better circulation, zinc might enhance heart function and alleviate chest pain.

Based on these findings, we propose that zinc treatment should be considered a fundamental option in both prevention and therapy for atherosclerosis-related chest pain. This could lead to a renewed focus on restoring a healthier cardiac function among those affected by these conditions.

We explored the effectiveness of a modified bismuth quadruple therapy that includes zinc carnosine, in comparison to the traditional triple therapy for treating indigestion caused by Helicobacter pylori infection. In our study, 92 patients with symptoms of dyspepsia and positive breath tests were randomly assigned to receive either the conventional treatment of esomeprazole, amoxicillin, and clarithromycin for 14 days, or a shorter 10-day course of the new therapy that also included bismuth subcitrate and zinc carnosine.

The results were quite revealing. Our findings showed that the modified bismuth quadruple therapy group had a significantly higher eradication rate of 93.5%, compared to 69.6% in the standard treatment group. This suggests that the addition of zinc carnosine to the treatment regimen could enhance the effectiveness of indigestion relief. Importantly, the side effects reported between the two groups were similar, with only mild dizziness noted in those receiving the new therapy.

Overall, the study indicates that a shorter course of therapy that includes zinc carnosine may be a superior option for individuals suffering from indigestion related to Helicobacter pylori. This approach not only appears to work better but also does not lead to more serious side effects, making it an appealing alternative to traditional treatment methods.

We explored how zinc oxide (ZnO), often used as a feed additive, affects diarrhea and gut health in piglets infected with the ETEC K88 strain. Through careful observation, we found that piglets suffering from this infection exhibited significantly increased fecal scores compared to those not affected. The ETEC K88 strain harms the small intestine, leading to a loss of villus height and a decrease in important antioxidant activities.

Our findings revealed that ZnO administration counteracts these negative effects effectively. It not only improved the overall health of the intestine but also enhanced its ability to combat oxidative stress. We also observed a balanced restoration of gut microbiota, as ZnO helped normalize the populations of certain beneficial bacteria altered by the infection.

In summary, our study indicates that ZnO can play a vital role in easing diarrhea in piglets infected with ETEC K88 by reducing intestinal damage, supporting antioxidative defenses, and restoring healthy gut flora.

J Trace Elem Med Biol. 2025;87:127558. doi:10.1016/j.jtemb.2024.127558

We conducted a study to evaluate how effective NPC-25, a new form of zinc, is compared to a well-known treatment, NOBELZIN™, for patients with low zinc levels. Participants in this trial had their zinc levels checked and were grouped to receive either NPC-25 or NOBELZIN™.

For a period of up to 24 weeks, we aimed to maintain their zinc levels within a specific target range while closely monitoring for side effects. One of our main goals was to see if NPC-25 could maintain these target zinc levels similarly to NOBELZIN™.

Our findings revealed that NPC-25 was indeed non-inferior to NOBELZIN™, meaning it worked just as well. Importantly, we also observed that those taking NPC-25 reported fewer digestive issues, like nausea and vomiting. This suggests that while both treatments were effective, NPC-25 might be the gentler option.

In our study, we examined how epipharyngeal abrasive therapy (EAT), which includes the use of zinc chloride, affects the expression of a key molecule known as Cav1.2. This molecule is essential for the influenza virus to enter cells, making it a crucial target in flu prevention strategies.

We compared two groups of patients: those who received EAT and those who did not. Our findings revealed that the levels of Cav1.2 were significantly lower in the EAT group, at a striking 4.19 times less than in the non-treated group. This suggests that the squamous metaplasia induced by EAT—which is a process of changing the epithelium—could be a beneficial approach to limiting flu infections.

The results of the study highlight zinc's potential indirect role in flu prevention by remarking on its contribution to lowering the expression of a critical receptor for the virus. Although we didn't isolate the effects of zinc alone, the findings indicate that treatments involving zinc, like EAT, may offer a straightforward way to help limit the impact of influenza.
