Alpha-Tocopherol

Alpha-Tocopherol is the most predominant Tocopherol (Vitamin E).

Alpha-Tocopherol is the typical form of Vitamin E and its health benefits are described in the topic for Vitamin E.

Vitamins

 When Alpha-Tocopherol is used as a supplement in isolation (i.e. without concurrent supplementation with other forms of Vitamin E) it may cause the depletion of Delta-Tocopherol.  ^[1]

 When Alpha-Tocopherol is used as a supplement in isolation (i.e. without concurrent supplementation with other forms of Vitamin E) it may cause the depletion of Gamma-Tocopherol.  ^[2]

Topical Bioavailability

 Alpha-Tocopherol has been demonstrated to be well-absorbed when applied topically to the Skin.

D-Alpha-Tocopherol

 D-Alpha-Tocopherol is the most commonly supplemented form of Vitamin E.

 The “D” denotes that this is a naturally-occurring form of Alpha-Tocopherol.  This "natural" form of Vitamin E is more costly to isolate, concentrate, and manufacture than dl-Alpha-Tocopherol is to synthesize, and is therefore approximately twice as expensive as synthetic Vitamin E, but has 1.4 times more Vitamin E IU activity and is retained within the body far more efficiently than synthetic Vitamin E.
