We set out to investigate how zinc might help protect heart cells from damage caused by a lack of blood flow, known as myocardial ischemia-reperfusion injury (MIRI). Using H9C2 cells, which are derived from rat heart tissue, we simulated this injury by depriving these cells of oxygen and then reintroducing it while treating them with zinc.
Through this process, we found that zinc treatment significantly increased cell viability compared to those that did not receive zinc. Cells exposed to ischemia showed typical signs of trauma, like heightened levels of apoptosis—or programmed cell death—and calcium overload, which can further damage cells.
Interestingly, zinc seemed to tackle these issues by lowering the levels of certain proteins related to cell death. It also played a role in regulating calcium levels by interacting with various cellular pathways. In fact, when we silenced specific proteins involved in these pathways, the protective benefits of zinc were even more pronounced.
Our findings suggest that zinc can relieve the harmful effects of ischemia by mitigating cell death and regulating calcium overload, which offers hope for future treatments for heart-related conditions impacted by blood flow interruptions.

We explored the relationship between atrial natriuretic peptide (ANP) and zinc, particularly how they work together to protect the heart during reperfusion after ischemia. The study involved comparing various experimental rats and mice, as well as assessing plasma samples from patients experiencing heart-related conditions.
Our findings highlighted that ANP significantly boosts zinc levels during the crucial period of reperfusion. This increase in zinc appears to protect heart cells from damage by helping to maintain mitochondrial health, effectively reducing the size of heart tissue injuries. We observed that when ANP was administered alone, it improved heart function, but combining it with a substance that removes zinc led to poorer outcomes.
We also noted that ANP works through a specific signaling pathway (the PI3K pathway) to decrease levels of a zinc transporter, ZnT8, which is upregulated during reperfusion injury. Interestingly, both ANP and zinc had a role in regulating important proteins linked to heart health. Overall, our research suggests that managing zinc levels through ANP treatment can help shield the heart from the harsh effects of ischemia/reperfusion injury.

We investigated how zinc levels may influence sleep duration in patients with cardiovascular diseases (CVDs). Our study included 150 participants from the Ravansar Non-Communicable Disease Cohort Study, where we measured serum concentrations of zinc and other elements, including essential minerals and toxic metals.
A significant finding was that we observed a strong correlation between higher zinc concentrations and optimal sleep duration. Specifically, the data indicated that as zinc levels increased, the likelihood of achieving an appropriate sleep duration of 7 to 8 hours also increased.
However, when we looked deeper into the data, we did not find significant differences in the serum concentrations of both essential and toxic elements across different sleep duration categories. This suggests that while zinc may play a role in regulating sleep duration, it does not entirely account for sleep issues among CVD patients.
Ultimately, our results encourage further exploration of zinc's impact, particularly as it relates to sleep quality and overall health in individuals with cardiovascular conditions.

Excellent! I purchased this zinc for our home medicine cabinet to combat viral illness. It should be taken with quercetin for better absorption, though I found that zinc alone was quite effective. It partially enters the bloodstream through the mucous membranes and begins combating viruses in the oral cavity, which is a significant advantage. I have always trusted this manufacturer and experienced no issues. Stock up for winter, I highly recommend it!

We focused our research on how zinc oxide nanoparticles (ZnONPs) might help reduce heart damage caused by cisplatin, a well-known chemotherapy drug. In this study, we used rats divided into different groups, some receiving varying doses of ZnONPs and others serving as control groups.
Our findings indicated that as the dosage of ZnONPs increased up to 50 mg/kg, there was a marked improvement in cardiovascular markers. We observed reduced levels of oxidative stress, inflammation, and cell damage in the heart tissues of those treated with ZnONPs. More specifically, measures related to heart tissue health and serum biomarkers showed that rats receiving higher doses exhibited recovery similar to that of healthy rats.
Overall, we concluded that ZnONPs serve as a protective agent against cisplatin-induced cardiotoxicity, showcasing their potential in improving heart health during cancer treatment.

We explored the relationship between dietary zinc intake and the risk of atherosclerotic cardiovascular disease (ASCVD) in patients with diabetes mellitus (DM). Utilizing data from the National Health and Nutrition Examination Survey (NHANES) between 2007 and 2018, we calculated the 10-year ASCVD risk according to established clinical guidelines. Our analysis focused on dietary zinc intake based on food recall data from the participants.
The findings suggest that sufficient dietary zinc intake could positively influence cardiovascular health in diabetes patients. This is particularly important, as diabetes is closely linked with increased oxidative stress and inflammation, two factors that contribute to the development of heart disease. While we see an association between zinc and improved heart health, it's essential to note that further research is needed. Large-scale, well-designed prospective studies should aim to clarify the specific role of zinc in this context.
Overall, our results underscore the potential benefits of zinc for cardiovascular health, particularly in individuals managing diabetes. As we delve deeper into these associations, we aim to provide clearer guidance on how dietary choices can impact health outcomes for those living with diabetes.

Quality product for immunity health. My doctor advised this zinc after I suffered from ARVI. I experienced significant hair loss and fatigue post-illness. Taking one tablet daily along with other supplements, I noticed improvement after two weeks; my general condition has steadily progressed, with less hair loss and no more nail issues.

Zinc's role in cardiovascular health
We explored how zinc deficiency relates to cardiovascular disease among obese adults in Serbia. By conducting a case-control study with 31 obese participants and 31 control subjects, we set out to understand how zinc affects body weight, lipid levels, and inflammation.
Our findings revealed that obese individuals had significantly lower serum zinc levels compared to those who weren't obese. We observed notable negative correlations between zinc levels and various health metrics, including body weight, body fat percentage, and triglycerides.
On the flip side, higher zinc levels correlated positively with beneficial high-density lipoproteins. Interestingly, we noted that the atherosclerotic index was significantly linked to zinc, suggesting that zinc status could play a role in assessing cardiovascular risk in obese individuals.
While this study spotlights zinc's intriguing relationship with cardiovascular risk factors, it does not specifically evaluate the benefits of zinc treatment on cardiovascular outcomes.
