Why not try something that is more NATURAL. I use an organic, wholefood product that helps with constipation and does not leave me with diahreah (sp?). This product is Cell Tech's Super Blue Green Alpha Sun and Omega Sun Algae. It is wild harvested and regulated by the USDA and FDA, is thoroughly tested and only available through distributors. I have a friend who has Parkinsons and has been taking the products (Liquid Omega and CoQ10) for about a month now and she has reported that she is experiencing more and more "good" days and fewer "bad" days. She also said that her lips are no longer blue. She is able to do things she was never able to do before, like sit up. Super Blue Green Algae helps to nourish the delicate neurotransmitters of the brain, thus helping the brain help itself. K Turvey
