Zinc’s effects on colds
Zinc for prevention and treatment of the common cold: Summary of a Cochrane review.
High relevance to cold treatment
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
Effects of different cold-resistant agents and application methods on yield and cold-resistance of machine-transplanted early rice.
Study highlights zinc's effectiveness
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.

Zinc mouthwash reduces cold symptoms
Efficacy of regular gargling with a cetylpyridinium chloride plus zinc containing mouthwash can reduce upper respiratory symptoms.
Focus on combined treatment effects
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.

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!

Long-term effectiveness
It works! Zinc supports the immune system. In combination with other supplements, this has kept me cold and flu-free for the past ten years!

Faster cold recovery
This Zinc product has worked wonderfully for me. I usually catch colds easily, especially in the winter when wet. This winter, even after getting cold twice, I recovered within a week without needing a doctor visit. I avoided the usual lingering cough, and I plan to buy my third bottle soon!

Cold prevention
AMAZING! Take one alongside Elderberry at the first sign of a cold, and it knocks it out. It's useful in preventing sickness if someone around you has a cold. It always resides in my medicine cabinet!

No sickness!
Awesome for keeping your immune system intact against viruses! I purchased these ahead of travelling to Bali and Dubai, knowing that a long flight could make anyone ill. I began taking them two weeks before my trip and have continued since, as I've not been sick this winter, not even a cold. I highly recommend them!
