Vitamin D supplements may cut heart attack risk: Study

A new study believes that vitamin D supplementation can prevent the elderly from cardiovascular problems, including heart attack. In one of the largest trials yet, researchers have discovered that vitamin D supplementation may cut the risk of cardiovascular events such as heart attacks in the elderly.
This particular randomized controlled trial involved around 21,000 people over 60 who were given a vitamin D supplement or placebo orally each month for up to five years. The findings have been published in the journal BMJ. The authors noted that while it was found that vitamin D supplementation could help prevent major cardiovascular events and more trials were needed. The finding proves that previous thinking that vitamin D supplements do not cut CVD risk was premature.
Vitamin D is fat-soluble and plays a role in the absorption of calcium, magnesium, and phosphate. It also reduces inflammation and affects cell growth, neuromuscular and immune function, and glucose metabolism.
The idea that vitamin D is useful for heart health is not new. Older observational studies discovered that people with higher vitamin D levels in the blood had lower rates of cardiovascular disease. People who exercise outdoors and eat nutrient-dense foods are more likely to have better Vitamin D levels than people who do not. The previous studies said that once people had sufficient levels of Vitamin D, the benefits of heart plateau and higher intake don't reduce changes of heart disease.
