    Default Vitamin E protects vitamin B-12

    From http://www.yourhealthbase.com/vitamin_B12.html

    LITTLE ROCK, ARKANSAS. Adenosylcobalamin is an important coenzyme, which is involved in the metabolism of branched-chain amino acids, cholesterol, methionine, and odd-chain fatty acids. It is synthesized in the cell nucleus from vitamin B-12 (cyanocobalamin). Now researchers at the University of Arkansas have found that the synthesis of adenosylcobalamin is impaired if the cell membranes have been subjected to peroxidative (free radical) attack. They also found, through experiments with cell cultures, that vitamin E effectively prevents the peroxidation and thereby allows the enzyme synthesis to proceed unhindered.

    ow do other nutrients interact with vitamin B-12?


    Vitamin B6 is required for proper absorption of vitamin B-12, and deficiency of vitamin B6 has been shown to impair B-12 absorption in animal studies.

    Conversion of vitamin B12 from its non-active into its biologically active form requires the presence of vitamin E. Individuals at risk for vitamin E deficiency may show signs of vitamin B12 deficiency as well.

    Contrary to research from the mid 1970s, supplemental doses of vitamin C above the 500 milligram level do not appear to compromise B-12 function.

    Excessive intake of folic acid can mask B-12 deficiencies, and individuals at risk for vitamin B12 deficiency who are also taking folic acid in supplement form should consult with their healthcare practitione
