My husband and I have been taking Superfood every morning since 1998. We notice the difference when we run out so then we order again! We also have used the Intestinal Formula 1 and 2 which are great, just as described by Dr. Schulze. We have also done the liver cleanse a few times which made our bodies feel younger. When I get a cold or flu I will take the Echinacea Plus which nips this in the bud. We have also recommended these products to our friends and family who have gotten similar results. To sum up our experience over the last 20 years have only been positive with this company.
