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.

We examined how incorporating fly ash into magnesium phosphate repair mortar (MPM) influences its effectiveness in cold environments. Our investigation revealed that fly ash modifies the microstructure of the MPM, enhancing its performance without affecting the setting time or fluidity significantly.
We discovered that adding 10% to 15% fly ash improves the mechanical strength, adhesion, water resistance, and stability of the mortar. Notably, we found that the curing temperature plays a critical role; as the temperature rises, compressive strength increases, while properties like flexural strength decrease.
Interestingly, even when cured in icy conditions at -20°C or 0°C, MPM with fly ash retains good early strength and strong adhesion properties. This suggests magnesium phosphate repair mortar modified with fly ash is suitable for emergency repairs in cold weather, showcasing its potential for use in challenging environments.

We examined the use of copper-magnesium (CuMg) alloys, particularly focusing on those with higher magnesium content, to understand how they perform during cold metal working processes. Our testing aimed to identify the effects of magnesium on the mechanical properties and workability of these alloys, as they’re known to provide significant solid-solution hardening.
The results revealed that CuMg alloys with 2 to 4 weight percent (wt%) magnesium displayed impressive strength characteristics, outperforming commonly used materials like pure copper and aluminum. We calculated improvements in hardness and Ultimate Tensile Strength (UTS), showing increases of up to two and a half times compared to pure copper. However, we noted that while magnesium enhances strength, it also raises friction during processing, which can complicate metal forming.
We learned that increasing magnesium content could lead to brittleness when it exceeded approximately 3.6 wt%, introducing challenges for cold working. This brittleness arises from the formation of specific phases, making it challenging to use these alloys in practical applications. Our findings suggest that while magnesium can significantly boost the mechanical properties of CuMg alloys, careful consideration is needed regarding its maximum content to maintain ductility and workability.

Magnesium enhances vascular preservation
We examined the effectiveness of modified Krebs-Henseleit (KH) solutions with low calcium and high magnesium levels on preserving vascular function during cold storage. Our focus was on whether adding adenosine and lidocaine could further improve the preservation of rat aortic rings after six days of cold preservation.
In our study, we found that traditional preservation solutions often fail to maintain proper vascular function after just three days of cold storage. However, when we tested a modified KH solution with lower calcium and higher magnesium, we observed significant recovery of contraction and relaxation functions in the aortic rings. This suggests that magnesium plays a vital role in preserving these functions.
Interestingly, while adding adenosine and lidocaine did not enhance contraction, it did improve the aortic rings' ability to relax in response to a chemical called acetylcholine. Furthermore, a histological examination showed that the addition of adenosine positively affected the endothelial lining and structural integrity of the vessels, highlighting its importance in cold preservation.
Overall, our findings suggest that magnesium in combination with adenosine significantly enhances the preservation of vascular structures and functionalities during extended cold storage, making it an important consideration for vascular grafts.

Magnesium improves beef storage safety
We explored the effects of incorporating hydrogen-producing magnesium into minced beef meat (MBM) to see how it affects quality and safety during cold storage. The study involved vacuum packaging the MBMs and storing them at 4°C for 12 days while comparing them with other treatments, such as gassing with hydrogen or nitrogen.
What we found was quite promising. The samples with magnesium showed the lowest browning index values, which indicates less color change and better visual quality. Additionally, these samples exhibited reduced bacterial counts, including mesophilic and psychrotrophic bacteria, as well as yeast and molds. This suggests that magnesium can help in maintaining the freshness and safety of the meat.
Interestingly, the magnesium treatment also limited the formation of potentially harmful compounds, such as thiobarbituric acid reactive substances and biogenic amines, which can negatively impact meat quality. By the end of the storage period, the control samples had the highest levels of volatile compounds, hinting at spoilage, while magnesium-enhanced and vacuum-packaged samples fared better.
Overall, we observed that using hydrogen-producing magnesium while handling minced beef could be an effective way to protect important quality attributes and safety during cold storage.

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.

I ordered it for my sister. Magnesium is absorbed in the evening (before and during sleep), so she takes the first pill at 8-9 pm and the second just before bedtime. The tablets are large but easy to swallow. Recently, it had become very hard for her to rise in the morning, and her general condition was unsatisfactory. She constantly felt tired, and catching colds became common. After starting the course, I noticed she began to feel significantly better—rising in the morning became easier, and she could manage her daily tasks with more ease.

Quick recovery
I'm pleased with this calcium; I've been using it for a short time but have already noticed an improvement in my immune system. I contracted a viral illness earlier but got over it quite quickly. A slight stuffy nose and general weakness were my only noticeable symptoms, but they cleared up in just two days! Previously, I would suffer from a cold for much longer. I even increased my zinc intake during this time and didn't experience any residual weakness.
7.5
Resilient immune system
I have been taking this supplement for a short time, and I’ve already noticed my immune system strengthening. I caught something viral, likely the most common virus of 2020, but recovered almost unnoticed. My only symptoms were slight nasal congestion and general weakness which passed in 2 days. My previous colds lasted much longer. I doubled my zinc dosage during that time, and I was delighted to find that my strength hadn’t decreased at all.
6
Easier cold recovery
Three trace elements in one preparation! I waited a long time for this complex, as it is quite rare. It's very convenient to have all three trace elements combined. Essential for the heart and immune system. I took this dietary supplement for a month: 2 capsules per day, then 1 capsule per day. In January, I dealt with a cold more easily, and I believe that this was the effect of this product.

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.
