Carlson Labs E-Gems Natural Vitamin E 400 IU 90 Softgels Carlson Labs E-Gems Natural Vitamin E are golden gelatin gems containing concentrated Natural-source Vitamin E oil, d-alpha tocopheryl acetate. Vitamin E is an essential nutrient and important antioxidant that promotes a healthy heart and cardiovascular system to help maintain your good health. E-Gems are twice as active as synthetic vitamin E inside our bodies. The Vitamin E is derived from soybean oil; synthetic Vitamin E is never used. With over 50 years of scientific research, Vitamin E has gained notoriety as one of the most predominant and active antioxidant nutrients. The amounts of Vitamin E effective within clinical studies are not obtainable, even from a well-balanced diet, and that is why many people choose a Vitamin E supplement. Scientists have found Natural Vitamin E is retained in the body many times longer than Synthetic Vitamin E. Vitamin E is essential to life. We can not survive without it! Several prominent researchers believe that to perform at its best, the human body needs more than the U.S. Daily Value (DV) of 30 IU Vitamin E daily. The average American diet supplies considerably less than this amount. Dr. Evan Shute, a Canadian physician internationally recognized for his 30 years of clinical work with Vitamin E stated, "We think that the average normal female should have 400 IU a day and the average normal male about 600 IU a day." Inorganic Iron can destroy Vitamin E. The Shute Institute was the first to discover and announce that inorganic iron, as ferrous sulfate, can be destructive to the Vitamin E when the two are taken together. They suggest that when inorganic iron and Vitamin E are taken, they should be separated in the stomach by an interval of 8 to 9 hours. Organic iron, however, such as that found in raisins, spinach and other iron-rich foods, can be taken at the same time as Vitamin E, with no harm to the Vitamin E.
