The study focused on understanding how dietary copper affects physiological issues tied to reduced levels of peptidylglycine alpha-amidating monooxygenase (PAM), especially regarding hypothyroidism.
We evaluated the impact of PAM deficiencies in mice and found that those with reduced PAM levels struggled with thyroid regulation and body temperature, particularly when they were hypothyroid due to dietary restrictions. Interestingly, while these mice showed normal hormone response to cold, they couldn't maintain their body temperature effectively as compared to their healthy counterparts in colder environments.
However, when we introduced additional dietary copper, these PAM-deficient mice were able to stabilize their body temperature just as effectively as the normal mice. It appeared that copper supplementation helped restore some of the physiological functions that were impaired by low PAM levels.
Overall, our findings indicate that low dietary copper might exacerbate the challenges faced by those with PAM deficiencies, suggesting that copper intake could be an important factor in managing related hypothyroidism symptoms.

I took this zinc to recover from COVID pneumonia, taking 60g for the first week and now 30g. I also give it to my 17-year-old daughter for her school challenges. I was concerned that it wouldn’t work, but thankfully, her acne has cleared, and her scalp is less oily due to hormones. My husband recently caught a cold, which developed into a lingering cough. I increased his dosage plus added vitamin D3 and vitamin C, and within two days, his symptoms improved remarkably! So, don’t underestimate the effectiveness of dietary supplements!

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 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!

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 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.

I had adrenal fatigue and was notably low on magnesium and zinc. My nails were fragile and would crack easily. Previously, I struggled to recover from colds. Initially, I took 1 tablet and now take 3 daily, as my needs seem to exceed the supply. While it’s not as strong-smelling as selenium and is small enough to take, it can weigh heavily on my stomach if I take 3. Hence, starting with half a tablet might be wise for sensitive stomachs. This supplement is essential for my adrenal fatigue, and after increasing my intake to 3 tablets, I notice that my fatigue has eased. Additionally, I’m taking 400mg of zinc and magnesium alongside 50mg of iron and 100mg of selenium.

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 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.

Zinc supplementation benefits MS models
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.

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.

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.

We aimed to explore how zinc oxide nanoparticles (ZnO NPs) could protect the heart from damage caused by doxorubicin, a drug that can lead to serious heart issues, including myocardial infarction (MI). Our study involved rats that were injected with doxorubicin to induce MI and then treated with ZnO NPs at two different doses.
Throughout the research, we observed significant improvements in heart health among the rats that received these nanoparticles. Specifically, their heart function showed recovery, with important biochemical markers reflecting less damage. The lower dose of ZnO NPs was especially effective, aiding the antioxidant system and boosting nitric oxide production, which is vital for heart function.
Our findings suggest that ZnO NPs could be a promising way to counteract the cardiotoxic effects of doxorubicin. This insight opens new avenues for treatment strategies aimed at patients who need chemotherapy without risking their heart health.

Zinc may alleviate anxiety symptoms
We explored the connection between zinc intake and anxiety in adults through a systematic review of nine original studies. Two of these studies looked at how zinc consumption impacts anxiety, while the other seven focused on the relationship between serum zinc levels and anxiety symptoms. Our analysis included studies published in English within peer-reviewed journals, ensuring a solid foundation for understanding this potential link.
What we discovered was quite illuminating. The data indicated that individuals experiencing anxiety often had lower levels of zinc in their serum compared to those who did not suffer from anxiety. Additionally, we observed an inverse association between zinc intake and anxiety levels. This suggests that higher consumption of zinc may contribute to reduced anxiety symptoms.
In conclusion, the evidence points towards zinc playing a positive role in treating anxiety, although we acknowledge some limitations in the available studies. This means zinc supplementation could be a beneficial strategy for those looking to manage their anxiety, but more research is needed to confirm these findings and understand the underlying mechanisms better.

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.

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.

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.

We evaluated the potential of zinc in combination with a ketogenic diet and oxyresveratrol in fighting glioblastoma, a highly aggressive brain tumor. Through a series of carefully designed experiments, we examined how these treatments affect tumor growth and overall brain function.
In our study, we induced brain tumors in Wistar rats and then applied our treatment regimen. We tracked various outcomes, including tumor size, proliferation rates, memory function, and motor coordination. By assessing glucose and ketone levels, we gained insights into the metabolic changes occurring as a result of the treatments.
The findings suggested that zinc played a supportive role alongside the ketogenic diet and oxyresveratrol in reducing tumor growth. Moreover, these treatments appeared to enhance memory and motor coordination, indicating a multi-faceted benefit. Overall, this progression offered valuable information about the role of diet and supplementary compounds in battling aggressive brain tumors like glioblastoma.

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.

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.

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.

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.

Zinc treatment reduces nausea risk
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.
