Natural vs. Synthetic Vitamin E

While there is only a slight difference between the natural and synthetic forms of most vitamins, when it comes to Vitamin E, natural is better.Natural vitamin E contains alpha-tocopherol exclusively in an active form, either as d-alpha tocopherol or stabilized as d-alpha tocopheryl acid succinate or d-alpha-tocopheryl acetate). Synthetic vitamin E (sometimes referred to as dl-alpha-tocopherol) contains both active and inactive forms of alpha-tocopherol. Natural vitamin E may also contain other types of tocopherols, including beta-tocopherol, delta-tocopherol, and gamma-tocopherol. Some manufacturers use the term mixed tocopherols when referring to these different types.

While little is known about the value of the beta and delta forms of vitamin E some researcher believe that gamma tocopherol may be as important as alpha-tocopherol. The results of a few test tube studies indicate gamma tocopherol might be more effective than alpha tocopherol in protecting against certain types of oxidative damage. Other research shows that supplementation with high doses of alpha tocopherol (such as 1,200 IU per day) increases the breakdown, and decreases blood levels, of gamma tocopherol.

To date, most human trials with vitamin E have been conducted using the alpha (not gamma) form. Historically the synthetic dl form was used in most trials, but much research is now focusing on the natural form. The relative value and effect of alpha vs. gamma form requires more research to be fully understood.The most important thing that research supports is that alpha-tocopherol is the most biologically active form of vitamin E. In it natural form alpha-tocopherol consists of one isomer. In contrast, synthetic alpha-tocopherol contains eight different isomers, of which only one is the same as the natural form. The other seven isomers found in synthetic alpha-tocopherol range in potency from 21 percent to 90 percent of natural d-alpha-tocopherol. So what does all this mean? It means that the body is able to assimilate natural vitamin E far better than synthetic E. Specific binding and transport Proteins produced in the human liver select the natural d-alpha form of vitamin E and largely ignore all other forms - those prevalent in synthetic E.

In one experiment, Japanese researchers gave natural and synthetic vitamin E to seven healthy young women. It took 300 mg of synthetic vitamin E to achieve the blood levels provided by a 100-mg dose of natural vitamin E.

In other long-term tissue assimilation studies on two cancer patients one patient was given 30 mg/day half natural, half synthetic vitamin E for one year, and the other patient was given 300 mg/day for almost two years. In both patients, blood and tissue levels of natural vitamin E rose twice as high as the synthetic.
