We have been in business for 35 years. We only carry QUALITY products. When taking vitamins and minerals you want to make sure you are getting more of a natural supplement then synthetic. There have been many studies on synthetic Vitamin E, and how it can cause respiratory problems. So we only carry a 100% natural vitamin E, and that is what you will find in our Super Vite. We are constantly reading health and nutritional journals to keep our knowledge of nutrition up to date and accurate. We also like to educate our customers about the supplements they are taking. If you have any questions or comments please feel free to give us a call at (816)765-1135 or 1-800-POWER21 email at super-vite@sbcglobal.net or by mail at 12706 S US 71 Hwy Grandview, Missouri 64030
