This study is a couple of years old but it is still very valid today. It’s become clear the vitamins we buy at our local pharmacy or grocery store are most likely inferior. This is why I use products from a good health food store with an owner who knows what they are talking about.
Good morning Stephen,
it's the same here in Grmany - better stay away from any artificial "health product"!
Fresh vegetables and fruit from a trustet store or directly from a farmer (often possible here) does more to our health than any bought chemistry.
Careful eating, not too much at atime, very thorough chewwing, and carefully watching the reactions of my body are my means to keep me out of trouble.
greetings
Rippi
