I've been told that I need to take a vitamin D supplement. Which one is the best?

The best Vitamin D supplement for you will depend on your individual needs, so it's important to consult with your doctor or healthcare provider to determine which type of Vitamin D supplement would be best for you. Generally speaking, Vitamin D3 (cholecalciferol) is the most bioavailable form and has the highest amount of activity in the body, so this may be the best choice for you.
