Zinc’s effects on colds
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.

Zinc enhances rice cold resistance
We explored the impact of zinc-amino acids chelate on cold stress resistance in machine-transplanted early rice. Our investigation included other cold-resistant agents like uniconazole and abscisic acid, but we found zinc to be particularly effective. When applied during the regreening stage, zinc notably enhanced rice growth by promoting tillering and increasing the leaf area, which led to better yields.

We noted that zinc-amino acids chelate improved antioxidant enzyme activities, which are crucial for helping rice withstand cold temperatures. The yield of rice treated with zinc was approximately 9.22% higher than with uniconazole and 7.14% higher than with abscisic acid.

Additionally, we observed that using 750 g/ha of zinc-amino acids chelate during the transplanting and regreening stages yielded the best results. The timing of the application played a critical role, as spraying during these specific phases maximized both yield and cold resistance.

Overall, zinc treatments stand out as a promising option for improving cold stress resilience in early rice, making it a key consideration for farmers dealing with cold climate conditions.

We explored the impact of regular gargling with an antimicrobial mouthwash that contains both cetylpyridinium chloride and zinc on upper respiratory symptoms. A total of 150 participants were split into two groups; one group just brushed their teeth, while the other group brushed and gargled with the mouthwash twice a day over three months.

Our findings revealed that those using the mouthwash experienced a 21.5% reduction in the frequency and an 11% decrease in the severity of respiratory symptoms. This strongly suggests that incorporating zinc, alongside cetylpyridinium chloride, can provide benefits for those suffering from cold-related symptoms.

However, it’s important to note that this study’s design involved multiple components, and we can’t isolate zinc’s effectiveness from the impact of the other ingredients. Still, the results encourage us to view mouthwash with these ingredients as a helpful addition to our daily hygiene routines, especially during cold and flu season.

Ultimately, this research indicates that gargling with a mouthwash containing zinc and cetylpyridinium chloride can indeed help alleviate some unpleasant cold symptoms, but we should be mindful of the combination's effects when interpreting these outcomes.

Restores sense of smell

Zinc helped restore my sense of smell and assists with colds. I take it post meals and experienced no side effects. I use it at the onset of cold symptoms. After three days, my sense of smell returned entirely, attributed to zinc.

No colds!

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!

Skin improves significantly

I have been taking zinc for over a year, and the effects are simply remarkable. I take it in two-month cycles, and my skin, hair, and nails have improved immensely. A trick for when I have a cold is to take four capsules daily, and the symptoms usually pass after a couple of days.

Rapid recovery
3 people found this helpful
I liked the product and am ordering my third bottle now. I took it before meals on an empty stomach, which caused nausea, but after eating, it was fine. It helped tremendously with colds, allowing me to recover much faster. When I got sick, I also took monolaurin and cat's claw separately. I usually took longer to recover, but with zinc, I felt better in just a few days. I’m delighted to find that zinc can so effectively assist with colds. Plus, I appreciate that it’s natural, sourced from brown rice chelate, and includes Vitamin C.

Boosts immunity

Since taking this zinc, my hair has been growing remarkably—so many small hairs have appeared! The recommendation is two tablets daily, but I only take one, and I still experience a great effect. I consume it in courses for two months each year during cold seasons, as it boosts immunity. When I sense a cold, I increase to two tablets daily for two to three days, and the illness subsides.

Excellent zinc! It's widely acknowledged how crucial zinc is for the immune system. I consume it at the earliest signs of a cold, or if I feel cold outside, and I often avoid colds for quite some time. Additionally, zinc supports reproductive health, particularly for men. It's an effective organic zinc, easy to take, and has no side effects.
