Based on 16 Researches

Serum zinc levels and efficacy of zinc treatment in acne vulgaris: A systematic review and meta-analysis.

Most Relevant Research

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!

Zinc supplementation benefits MS models

Based on 6 Researches

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.

Most Relevant Research

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.

Quantile Treatment Effect of Zinc Lozenges on Common Cold Duration: A Novel Approach to Analyze the Effect of Treatment on Illness Duration.

Most Relevant Research

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.

Cold Sores

Zinc cream alleviates cold sores

Based on 9 Researches

A randomized clinical trial on the treatment of oral herpes with topical zinc oxide/glycine.

Most Relevant Research

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.

Hypothyroidism

Zinc's uncertain role in hypothyroidism

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.

Most Relevant Research

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.

Zinc’s effects on colds

Zinc for prevention and treatment of the common cold: Summary of a Cochrane review.

Most Relevant Research

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.

No colds!

Most Useful Review

No illnesses in 6 months! Since starting these after my re-activation of Epstein Barr Virus in December, not only has it helped suppress the mono, but I've not been ill with any other sicknesses, including colds and flus! I take half the recommended dose each day and have not fallen sick at all in 6 months! This is significant for me, as I used to get sick often!

Flu

Zinc treatment impacts flu virus entry

Epipharyngeal Abrasive Therapy Down-regulates the Expression of Cav1.2: A Key Molecule in Influenza Virus Entry.

Most Relevant Research

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.

Alleviating effect of intranasal zinc on symptoms of allergic rhinitis.

Most Relevant Research

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.

Questionable

Based on 4 Researches

Randomized, multicenter, active-controlled open-label study of NPC-25, zinc histidine hydrate, (non-inferiority to NOBELZIN™, zinc acetate dihydrate) for patients with hypozincemia.

Most Relevant Research

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.

Sleep Apnea

Zinc protects heart function in OSA

Likely Very Effective

Zinc Is Indispensable in Exercise-Induced Cardioprotection against Intermittent Hypoxia-Induced Left Ventricular Function Impairment in Rats.

Most Relevant Research

We explored how zinc affects heart function in the context of obstructive sleep apnea (OSA), specifically focusing on cases of intermittent hypoxia (IH). In a detailed study using male rats, researchers set up different groups: a control group and one that underwent 10 weeks of exercise training. Half of the rats in both groups were exposed to IH conditions to simulate the effects of sleep apnea.

The results were eye-opening. Rats that experienced IH showed notable impairment in their heart's left ventricular function, characterized by reduced ejection fraction and increased inflammation. However, when treated with zinc, these negative effects were significantly countered. Notably, those who exercised and received zinc treatment displayed improved heart function and antioxidant capabilities compared to their counterparts that did not receive zinc.

On the flip side, exercise alone did not provide the same protective benefits when zinc was absent. The findings suggest that zinc is essential not only for the heart's protection against the damaging effects of IH but also enhances the benefits of physical exercise. This research indicates the importance of zinc in potentially managing heart health in individuals suffering from sleep apnea.

I feel more harmonious and calm now. I recommend taking 2 capsules post-meal. I've ordered two more packs!

Efficacy and tolerability of zinc acetate for treatment of chronic refractory cough: pilot randomised futility trial.

Most Relevant Research

We conducted a pilot trial to explore the effectiveness of zinc acetate in treating chronic refractory cough, a condition that causes significant discomfort for many people. In this study, we compared zinc acetate against a placebo over a period of six weeks, with the aim of measuring improvements in quality of life and cough symptoms using several established questionnaires.

Our group included 34 participants who were primarily white females suffering from moderate to severe cough. Throughout the trial, we noted that those taking zinc acetate did experience a rise in serum zinc levels, which indicates that the treatment was effective in that regard. However, when assessing the overall impact on cough symptoms and quality of life, both the zinc and placebo groups showed improvements, but those improvements were minimal.

Importantly, the treatment effects observed did not reach the clinically meaningful thresholds that would suggest zinc acetate significantly benefits cough management. Therefore, we concluded that there is no substantial advantage to using zinc therapy over placebo for people dealing with chronic cough, and suggest that larger trials are unnecessary at this time.

Symptom Profile of Patients With Post-COVID-19 Conditions and Influencing Factors for Recovery.

Most Relevant Research

We explored how zinc acetate hydrate impacts hair loss for patients experiencing symptoms after COVID-19. In our analysis, we looked at 120 symptomatic outpatients over 12 weeks, observing their recovery patterns and any improvements in their symptoms. The focus was on various lingering effects, including fatigue and hair loss, particularly how zinc could potentially alleviate these issues.

Our findings highlighted significant improvements in hair loss for those treated with zinc acetate hydrate at multiple checkpoints (4, 8, and 12 weeks) compared to those who did not receive this treatment. The results were statistically significant and suggested that zinc could be a useful option for those struggling with hair loss post-COVID-19.

Additionally, we noted improvements in fatigue among those receiving zinc, although this was not as pronounced at all time intervals. As a whole, our study emphasized zinc's beneficial effects, particularly for hair loss, providing promising insights for anyone dealing with these challenging post-viral symptoms.

Treatment of Plantar Warts with a Nitric-Zinc Complex Solution: A Review of 72 Cases.

Most Relevant Research

We explored a new treatment approach for plantar warts using a nitric-zinc complex solution. In this study involving 72 patients, we aimed to observe how effective this solution is in achieving complete healing of warts.

The results were promising, showing a 59.2% cure rate after treatments. On average, patients received about 5.9 applications of the solution over a duration of around 9.4 weeks. Additionally, the recurrence rate was relatively low, noted at 6.7%.

Although we can’t isolate the specific contributions of zinc alone since it was part of a combined treatment with nitric acid, these findings suggest that the nitric-zinc complex could serve as a viable option for those suffering from plantar warts. This treatment may be considered among the first-line options for managing this common skin condition.

Arthritis

Zinc alleviates arthritis symptoms

Therapeutic Dose of Zinc Aspartate and Zinc Citrate Attenuates Disease Activity Indices in Rheumatoid Arthritis.

Most Relevant Research

We explored the effects of zinc supplements—specifically zinc aspartate and zinc citrate—on reducing the symptoms of rheumatoid arthritis. In our study, we induced arthritis in male Wistar rats using a collagen-related method and then treated the rats with these zinc compounds over a four-week period. Our objective was to evaluate how these compounds could impact the disease's severity and markers associated with rheumatoid arthritis.

The results were quite promising. Both zinc aspartate and zinc citrate, administered at a therapeutic dose of 50 mg of elemental zinc per day, showed a significant reduction in the clinical symptoms associated with arthritis. Furthermore, these compounds displayed antibacterial properties against Escherichia coli, which is notable since rheumatoid arthritis patients often suffer from increased sensitivity to bacterial infections.

Importantly, we found no adverse effects on liver or kidney function in the rats that received the zinc treatment. This highlights the potential of zinc compounds not only as anti-inflammatory agents but also as preventive measures against microbial growth that can complicate rheumatoid arthritis.

Zinc-containing yeast extract promotes nonrapid eye movement sleep in mice.

Most Relevant Research

We explored the effects of zinc on sleep by looking at how it might help with insomnia. In our study, we gave mice a zinc-containing yeast extract and monitored their behavior and brain activity. The results were quite promising.

We found that administering zinc at doses of 40 and 80 mg/kg led to a significant increase in non-rapid eye movement (NREM) sleep. This means that the mice were not only sleeping longer but also showed less activity, which is a good indicator of effective sleep. Interestingly, we did not observe any changes in rapid eye movement (REM) sleep, a crucial sleep phase for dreaming and deep rest.

Importantly, we didn’t see any negative side effects, such as rebound insomnia, within 24 hours after treating the mice. This suggests that zinc could be a safe option for those struggling with sleep issues, unlike other mineral extracts we tested, such as manganese, iron, and copper, which did not affect locomotor activity at all.

Overall, our findings provide the first evidence that zinc has a direct role in promoting sleep, opening up exciting possibilities for new sleep supplements featuring this essential mineral.

Psoriasis

Zinc conditioner benefits scalp psoriasis

Efficacy and safety of supramolecular active zinc in the treatment of scalp psoriasis: a multicentre, randomized, observed-blind, parallel-group, placebo- and active-controlled noninferiority trial.

Most Relevant Research

We delved into the effectiveness of a zinc-based hair conditioner specifically designed for treating scalp psoriasis. This study was a well-structured clinical trial involving 211 participants, where individuals were divided into three groups: those receiving the specialized zinc treatment, a placebo, and a control group given calcipotriol ointment. Remarkably, the trial was multicenter and observed-blind, which adds credibility to the findings.

Our results revealed that the zinc conditioner led to a 39% disease control rate after four weeks, compared to 25% for the placebo and 37% for the calcipotriol ointment group. This means that the zinc treatment significantly outperformed the placebo while being on par with the active control variant. In essence, those using the zinc product experienced better management of their scalp psoriasis than those using a non-active alternative.

Overall, our findings highlight that a supramolecular active zinc antidandruff formulation is not just effective for treating scalp psoriasis but also helps in maintaining results over time and potentially preventing future flare-ups. This offers a promising new avenue for patients seeking relief from this chronic condition.

Prostate Cancer

Zinc's complex role in prostate cancer

Prostate cancer-selective anticancer action of an oxindole derivative via HO-1-mediated disruption of metabolic reprogramming.

Most Relevant Research

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.

Active Packaging of Immobilized Zinc Oxide Nanoparticles Controls Campylobacter jejuni in Raw Chicken Meat.

Most Relevant Research

We set out to explore how zinc oxide nanoparticles (ZnO NPs) could help control the bacteria responsible for food poisoning in raw chicken meat. Our approach involved integrating these nanoparticles into packaging materials to see if they could effectively inactivate Campylobacter jejuni, a common and concerning pathogen in poultry.

Through our experiments, we discovered that immobilizing ZnO NPs in functional pads placed under raw chicken could dramatically reduce bacterial counts. In fact, we saw a reduction from about 4 log CFU to an undetectable level within just three days when storing chicken at 4°C. Notably, we monitored zinc levels in the chicken meat, confirming a safe release of zinc without any migration of nanoparticles onto the food. This means that we can help keep raw chicken safe and fresh without compromising its integrity or quality.

Not only did we find that these functional pads inactivated the harmful bacteria, but we also noted a related increase in lactic acid production, which plays a role in further protecting the meat. Our findings open up new avenues for using zinc in food packaging, offering a way to enhance food safety without directly adding chemicals to the food itself. Overall, this study highlights the potential for nanotechnology to play a significant role in managing foodborne pathogens like Campylobacter in poultry products.

Eczema

Zinc enhances eczema recovery

Based on 7 Researches

Transient symptomatic zinc deficiency in an exclusively breastfed infant.

Most Relevant Research

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.

Tinnitus

Zinc intake affects tinnitus risk

The Association between Dietary Intakes of Vitamins and Minerals with Tinnitus.

Most Relevant Research

We examined how dietary intakes of vitamins and minerals, particularly zinc, could influence the onset and presence of tinnitus, a condition characterized by phantom sounds in the ears. In a study involving nearly 3,000 participants over the age of 50, we identified cases of tinnitus to determine if their dietary habits played a role in their experience of this condition.

The findings indicated that while there were no significant associations between overall vitamin and mineral intake and existing tinnitus prevalence, zinc intake stood out in relation to developing tinnitus over time. Specifically, we observed that lower zinc consumption was linked to a 44% increased risk of experiencing tinnitus over a ten-year period.

Furthermore, we noted that iron intake also showed a significant correlation, with lower iron levels raising incident tinnitus risk by approximately 35%. These results highlight the potential importance of maintaining adequate zinc and iron levels in our diets to help reduce the risk of developing tinnitus.

Treatment for osteoporosis in people with beta-thalassaemia.

Most Relevant Research

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.

Headache

Zinc reduces migraine symptoms

Based on 8 Researches

Assessing the Effect of Zinc Supplementation on the Frequency of Migraine Attack, Duration, Severity, Lipid Profile and hs-CRP in Adult Women.

Most Relevant Research

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.

Zinc supplements for preventing otitis media.

Most Relevant Research

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.

My son used Vitamin Code Raw Zinc for his sinus infection, which cleared within four to five days, avoiding antibiotics altogether. This combination has positively impacted our health.

High-dose zinc to terminate angina pectoris: a review and hypothesis for action by ICAM inhibition.

Most Relevant Research

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.
