Logo/Brand desing for a functional food nutrition line

I am launching a functional foods line of products to include at least 2 flavors of bars and 3 flavors of meal replacement shakes. The line of products will be sold primarily through health care practitioners on the front end, then through direct response, ecommerce and ultimately mass retail. The attributes of the products are gluten free, vegetarian protein, vegetarian omega 3s, high fiber, antioxidants, digestive enzymes, low glycemic and Non-GMO. I need a logo that captures the essence of the brand.
