Dec 07, 2018· DL alpha tocopheryl acetate is a racemic mixture of D and L forms of alpha tocopheryl acetate. Hence, it is a form of a synthetic mixture of tocopherol molecules, and it is one of the most potent antioxidant tocopherols.
Tocopheryl acetate is a form of vitamin E, a natural skin-conditioning agent and antioxidant. It is the ester of acetic acid and tocopherol and is often used as an alternative to pure tocopherol (or undiluted vitamin E) because it is considered more stable and less acidic.
About TOCOPHEROL: Tocopherols are a class of naturally occurring chemical compounds related to Vitamin E. Function(s): Antioxidant; Fragrance Ingredient; Skin-Conditioning Agent - Miscellaneous;Skin-Conditioning Agent - Occlusive; SKIN CONDITIONING
For the movement and coordination disorder called dyspraxia in children: vitamin E (dl-alpha tocopheryl acetate) in combination with fish oil, evening primrose oil, and thyme oil (Efalex, Efamol Ltd) daily. For improving male fertility: vitamin E 298-894 IU daily. For Alzheimer's disease: up to 2000 IU daily.
In contrast, synthetic forms of vitamin E are labeled with a dl- prefix. Alpha-tocopherol is the most biologically active form of vitamin E, and its natural form consists of one isomer. In contrast, synthetic alpha-tocopherol contains eight different isomers, of which only one (about 12 percent of the synthetic molecule) is identical to natural vitamin E.
Since d-alpha tocopheryl acetate has the same bioavailability as alpha tocopherol, the recommendations are the same, explains the Linus Pauling Institute. As an adult, you need 15 milligrams, or 22.4 international units of vitamin E in either of these forms each day.
If you are getting 400 IU of natural d-alpha tocopherol (d-alpha tocopheryl succinate or acetate), it is equal to about 800 IU of synthetic dl-tocopherol (dl-alpha tocopheryl succinate or acetate).

D-alpha tocopheryl succinate is just another name for natural vitamin E. It is also called d-alpha tocopherol, which may be followed by the words "acetate," "succinate," or "acid succinate."
Vitamin E is available in various forms, including d- or dl-alpha tocopheryl acetate, d- or dl-alpha tocopherol, and d- or dl-alpha tocopheryl acid succinate. The synthetic form of vitamin E is dl-alpha tocopherol, while the natural form of vitamin E is d-alpha tocopherol.
Vitamin E 400IU from Nature's Way is natural d-alpha tocopherol delivered in a once-daily oil soluble softgel. Vitamin E is a potent well- researched and publicized antioxidant necessary in human nutrition. Antioxidants help combat free radicals and oxidants, molecules which damage fats and cells.

Sigma-Aldrich offers a number of DL-alpha-Tocopherol acetate products. View information & documentation regarding DL-alpha-Tocopherol acetate, including CAS, MSDS & more.
Tocopherol and tocopheryl acetate can be made naturally from vegetable oils or synthetically from petroleum products. The two have distinct names for supplement labeling; d-alpha tocopherol or tocopheryl acetate distinguishes a naturally derived supplement while dl-alpha tocopherol or tocopheryl acetate distinguishes a synthetic supplement.
Manufacture: Dl-alpha tocopheryl acetate is produced synthetically by the condensation of 2,3,5-trimethylhydroquinone with isophytol in an inert solvent (e.g. benzene or hexane) with a catalyst such as zinc chloride. The resulating alpha tocopherol is then treated with acetic anhydride to give tocopheryl …

Jan 18, 2016· The present study was conducted to compare the supplementation of natural (D-α-tocopherol) and synthetic (DL-α-tocopherol acetate) vitamin E on the growth performance, meat quality, muscular antioxidant capacity and genes expression related to oxidative status of broilers.
Nov 12, 2004· Based on what we know now, my advice is still to take supplemental vitamin E in doses up to 400 IU a day but not exceeding that. Avoid dl-alpha-tocopherol and look for products that include all four tocopherols, not just the d-alpha form. Better yet, try to get the whole vitamin E complex: four tocopherols plus four tocotrienols.

Stereoisomers of alpha-tocopherol. This mix of stereoisomers is often called dl -α-tocopheryl acetate.  However, 1 IU of this mixture of diastereomers is not now considered equivalent to 1 IU of natural RRR -α-tocopherol, and the Institute of Medicine and the USDA now convert IU's of the racemic mixture to milligrams.
