It's difficult to know what works. I hear you should choose a capsule rather than a pill as they are easier absorbed? I don't know how true that is. I also hear that you have to eat in the right proportion to get the most out of vitamins. Like eat protein with leafy greens to get the most out of it? I don't know the truth. I just know I pee glow in the dark yellow when I take them! Best advice would be to go to a healthfood store and find someone knowledgeable.
