Yeah, I've heard of it. I would never try it. I love eating, I love different flavours en textures. I think it is more healthy to get vitamins en nutrients from fresh and natural sources. Drinking some powdered vitamins does not sound pleasant for me. I would get bored with it in 1 or 2 days. It takes all the pleasure out of eating and cooking. Eating -for me at least- is much more than just getting my calories and nutrients...
