Vitamin D Supplements May Improve Blood Pressure, Cholesterol, and Insulin

ISLAMABAD: A recent meta-analysis reveals that an average daily supplemental dose of 3,320 IU of vitamin D is linked to lower blood pressure, total cholesterol, hemoglobin A1C, and fasting blood insulin and glucose levels.

This conclusion is drawn from a comprehensive review of 99 randomized controlled trials (RCTs) conducted globally, focusing on the advantages of vitamin D for cardiometabolic health.

The authors found that a median intake of 3,320 International Units (IU) of vitamin D per day, approximately 83 micrograms, was correlated with several important cardiometabolic advantages.

These advantages included reductions in both systolic and diastolic blood pressure, overall cholesterol levels, hemoglobin A1C (a marker for type 2 diabetes), and fasting blood glucose and insulin.

Researchers from China and the United States examined 99 RCTs published up to March 26, 2024, involving 17,656 participants from diverse populations worldwide.

A crucial aspect of the meta-analysis was identifying differences among the RCTs that could clarify their varying conclusions. By understanding these differences, the authors were able to re-evaluate and compare the data more equitably.

The findings were less influenced by conflicting results, revealing specific cases related to certain populations.

The researchers discovered that vitamin D supplementation was most beneficial for non-Western individuals, those with lower circulating levels of vitamin D, individuals with a BMI below 30, and people aged 50 and above.
