Synthetic vitamin E, designated dl-alpha-tocopherol, is the less expensive cousin of the naturally occurring form, d-alpha tocopherol. The natural form of the vitamin is synthesized only by plants and is found predominantly in plant oils. Vitamin E (tocopherol) is also present in high amounts within the chloroplast and therefore the leaves of most plants. In contrast, the tocotrienols are synthesized and found in the germ and bran sections of the plant (9). The fat-soluble property of vitamin E allows it to be stored within fatty tissue of animals and humans. Therefore a diet that includes meat supplies additional vitamin E. However, the amount of vitamin E obtained in a meat inclusive diet is less than the amount supplied by plant sources.

Absorption of vitamin E is highly dependent upon the same processes that are utilized during fatty acid digestion and metabolism. Common, and critical, to both fat and vitamin E absorption are micelle and chylomicron formation. A lack of any comp ...more

. Many foods are good sources of vitamin E, especially those that contain some amount of fat. However, a few fruits and vegetables also contain the vitamin. The recommended daily vitamin E intake for men and women is 15 mg per day. Add a few of these foods to your diet to ensure proper vitamin E intake.
Absorption of vitamin E is highly dependent upon the same processes that are utilized during fatty acid digestion and metabolism. Common, and critical, to both fat and vitamin E absorption are micelle and chylomicron formation. A lack of any component of these transporters will inhibit carrier formation and in turn vitamin E absorption. Bile acids are considered essential for vitamin E absorption and micelle formation. Once formed, the micelle is then able to cross the unstirred water layer and release its contents into the enterocyte

First of all we need to understand vitamin E is present in varying quantities in a whole host of plants like almonds, kiwi fruits, and mangos. Vitamin E consists of several natural compounds, including alpha, beta, delta, and gamma tocopherol. The combination of these vitamin E compounds is also known as mixed tocopherols.

The vitamin E family is well known for its antioxidant capabilities. Antioxidants protect vital cell structures by neutralizing molecules called free radicals. Free radicals are unstable molecules produced from sources like air pollution, radiation, and peroxides. Free radical damage can occur throughout the bodys several systems and ultimately lead to many diseases.
Antioxidants like vitamin E work to neutralize free radicals and stabilize cell membranes by providing the electrons needed to complete the unstable cell. Vital skin cells need to be protected by antioxidants. This is why the incorporation of antioxidants like vitamin E into skin care products is so ...more
