I can't say I am a huge fan of all the companies now out there that push nutritional information or supplements. But there is one that I believe has a good record with helpful products. Shaklee.
There are quite a few things I would not purchase as I just don't buy that you have to take all these things to be healthy. However, I do use their soy protein, multi-vitamin and Omega Guard which is an Omega3 supplement.
I can order my items online, without the hassle of going to the store. For me this is a plus. If you need or want more information you can find it here http://www.shaklee.net/tawnia
