Nutritional Tree-Great Natural Products

I have been researching different "natural" products in an effort for finding things that might help my little guys. I have looked at a couple of different companies. The company that I plan on trying out next is called, "Nutritional Tree". I plan on trying out the probiotic products that the Nutritional Tree sells. I would love to hear any ideas from people who have used their products or know of different companies that have similar products.
