Scientists from Peking University and other Chinese research institutions, in collaboration with experts at Columbia University and the Center for Global Cardiovascular Health, Brown University (USA), conducted a meta-analysis of 99 studies, involving 17,656 participants with an average age of around 50.
People who supplement with vitamin D have better blood pressure (both systolic and diastolic).
The authors extracted data from studies to investigate the effectiveness of vitamin D supplementation in improving metabolic cardiovascular risk factors.
The results showed that vitamin D supplementation helps improve all indicators of cardiovascular and metabolic health, according to the health website Healthline .
Specifically, those who supplemented with vitamin D had better blood pressure (both systolic and diastolic), total cholesterol, fasting blood glucose, mean corpuscular glucose (HbA1c), and fasting insulin levels.
In particular, the effect is stronger in people who are deficient in vitamin D, are not obese, are 50 years of age or older, and those who have been taking vitamin D for more than 3 months.
And the average dose to achieve these benefits is 3,320 international units (IU) daily. But the authors also emphasize that dosages vary from person to person, as each individual's response is different.
Researchers said the results suggest that obese individuals and older adults need higher levels of vitamin D to maintain cardiovascular health.
How much vitamin D should I take each day?
Akanksha Kulkarni, a nutritionist at Prowise Healthcare (UK), advises caution as vitamin D can be toxic if taken in excessive doses for extended periods.
She emphasized that it's best to consult a doctor before taking large amounts of vitamin D.
The U.S. National Institutes of Health states that the recommended daily intake of vitamin D for adults aged 19-70 is 600 IU, and for those over 70 it is 800 IU.
A dose of 4,000 IU per day is considered safe. Higher doses should be administered under medical supervision.
The best way to get enough vitamin D is through sun exposure.
