Additionally, some top-rated products were found to contain questionable ingredients that could potentially increase the risk of cardiovascular diseases and even carcinogenic substances.
TNE: Given these findings, what should consumers be on the lookout for when choosing a Vitamin D supplement?

Experts generally recommend a daily intake of 800 to 1,000 international Units (I.E.) of Vitamin D to maintain healthy levels,especially during winter. Reading labels carefully to avoid excessive amounts is key, and consulting with healthcare professionals before starting any new supplement is highly advisable.
