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.

Effective zinc
26 people found this helpful
Tastes great and chewable! When down with a cold or flu, one is willing to try anything. The only thing with scientific backing seems to be zinc, which helps your body create white blood cells to combat ailments. The zinc I used to have were large, hard-to-swallow pills, and I wasn't even sure if they digested properly. This product removes the uncertainty as they dissolve almost instantaneously. I’ve discarded my old zinc pills and rely solely on these, which also work well as a preventive measure.

Cold duration shorter
12 people found this helpful
This is essential for colds! Zinc effectively combats a cold if symptoms appear, and it shortens the duration if you already have it. It has always worked for me, and I recommend it to everyone. Even during this season's persistent flu/cold, it took a bit longer but ultimately helped me recover.

Fruity and effective
11 people found this helpful
Tasty and effective. Works perfectly when I sense a cold approaching. A couple of pills, and my symptoms, such as headaches or aches, vanish. However, they don't help if you're already experiencing a cold. I use it preventively, and the chewable pills are far more appealing than traditional medicine. They have a lovely fruity, sweet taste. Highly recommended!

Slows cold progression
7 people found this helpful
The best zinc. I would recommend this product to anyone who has a cold or feels one coming on. It's my go-to whenever my throat feels off, a warning sign of a cold. For me, it slows the progression of the cold to a couple of days. I will purchase again.

Miraculous supplement
4 people found this helpful
Zinc is a miraculous supplement for me. Whenever I feel a cold approaching, I let these dissolve near the back of my throat as directed. Sometimes they completely eliminate my cold, while other times I experience only mild symptoms. I recommend zinc to everyone, as in my experience, it works wonders! They also taste like vitamin C, a flavour I quite enjoy.
