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.

I take it for myself and my mother. With cold symptoms, I drink two a day. It's an irreplaceable assistant in my first aid kit, and after a couple of days, the illness is less noticeable.

As part of zinc gluconate, it is well suited for treating colds. When I had a cold, the illness was milder, and after a couple of days, everything was resolved. Zinc gluconate is particularly effective if you're deficient in zinc. I recommend it for prevention and immune support.

This very high dosage is appropriate for the cold season when taking a quick “shock” course for 5-10 days. I mix it with vitamin D, C, and fish oil – mmm, I didn’t get sick.

Cold symptom relief
I purchased zinc for my family to take during moments of colds. I tried it myself, and on the first day of feeling unwell, I began taking it with vitamin C. After 2 days, I had no cold symptoms.

I haven't had a cold for two years. My doctor advised taking this zinc 50 mg twice a year for two months. My husband and I have followed this regimen and never caught a cold. Last year, I added vitamin C and vitamin D3 for added support, and I highly recommend this approach.

Prevents lung issues
Zinc must be taken at the first sign of a cold, alongside vitamin C and D. It protects the body and prevents lung infections. I strongly recommend it during a pandemic at the first symptoms of a cold.

Effective for colds
I absolutely love this brand and this supplement; it is far superior to what my doctor prescribed. After using it consistently for two months, I began seeing results. I feel good, my immune system has improved, and I no longer get sick easily with colds, thank goodness!

Immediate response
You have found what you need! No longer search for effective remedies at the first symptoms of a cold! A double dose in the early days of a cold leads to an instant response from my body. Remember to take zinc NOT ON AN EMPTY STOMACH (half an hour after eating) to avoid nausea.
