What vitamins should i be taking as supplements?

Best via diet: The absolute BEST way to get vitamins is through a solid antioxidant anti-inflammatory diet. Even "natural" supplements get processed via heat or enzymes making them not as good or as complete as those you get from a good diet. Having said that, Vitamin D deficiency is very common, even if you are in the sun. Everyone is different. Look at diet first! A multivitamin won't hurt, but may not help.
