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.

Effective flu prevention

These small zinc tablets are taken daily during the COVID-19 pandemic to protect against flu and other infections. They effectively help avoid the common cold and flu. I find them better than Echinacea. When travelling during flu season, they are particularly useful for protection.

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.

Normalised hair loss
Most Useful Review
I experienced abnormal hair loss and had my blood tested for zinc and iron deficiency, which led me to purchase two bottles of zinc from iHerb. After two to three months of supplementation, my levels normalised. I am very pleased with the results and recommend it to anyone who is zinc deficient.

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!

Skin significantly improved
Most Useful Review
Good Zinc helped with acne. I really liked the 30 mg dose; it's just right. I took it for acne, alongside brewer's yeast, vitamin A, and omega 3. Thanks to these remedies, my skin has improved significantly—much better than before. After a month of use, I've noticed clear results with post-acne marks disappearing. The effect was noticeable by the second week. I highly advise it. If you find this review helpful, please click YES. Good luck to everyone :)

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.

Quick recovery
Most Useful Review
Quick! I usually buy nature made at the store but forgot this time; luckily, Amazon shipped it the next day. I use zinc at night to aid sleep. I swear by it when sick; it helps me recover from colds much quicker. 30mg is the perfect amount for me, as higher doses cause nausea.

Bone pain relief
Most Useful Review
The best element for men. I am 48 and have been taking zinc preparations (25 to 50 mg daily in the morning) for more than two years, with occasional breaks. During this period, I did not take sick leave for SARS or other viruses, even though those around me were unwell. I noticed that the bone pain has subsided, my hair has stopped falling out, and bald patches have significantly improved. My skin is much clearer than it has been since adolescence, and my libido has increased. Additionally, my cravings for alcohol and unhealthy food have diminished. Zinc is crucial for men, especially as deficiency can lead to abdominal fat accumulation. I recommend this dosage for anyone wishing to live a full and healthy life, regardless of age, with zinc gluconate suggested in the morning with food. No side effects were noticed. Thank you for the like. All the best.

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.

We were thrilled to find zinc, as it’s hard to get during the pandemic. I was sceptical, but this zinc really works. At the first hint of a common cold, I take it, and relief is usually felt by the next day or within two days. Highly recommended!

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.
