In a recent study, zinc supplementation demonstrated a protective effect on the heart by functioning as an anti-inflammatory and antioxidant.
Chronic inflammation and oxidative stress are important risk factors for heart disease. Zinc is an essential mineral with both anti-inflammatory and antioxidant functions. Because of these properties, zinc may play a role in protecting the heart.
To examine the effect of zinc on markers of inflammation, researchers conducted a randomized, double-blind, placebo-controlled trial of zinc supplementation in elderly subjects. Forty healthy elderly subjects (aged 56-83 years) were randomly assigned to 2 groups. One group received placebo; the other received 45 mg of zinc per day for 6 months.
Compared to the placebo, six months of zinc supplementation increased plasma zinc concentrations and decreased several markers associated with inflammation. Higher zinc levels were also related to a decrease in markers associated with oxidative stress.
The findings of this research suggest that zinc may have a protective effect in coronary artery disease thanks to its anti-inflammatory and antioxidant properties.
