Product Information

A meta-analysis from 2015 reported that for studies which reported serum tocopherol, higher serum concentration was associated with a 23% reduction in relative risk of age-related cataracts (ARC), with the effect due to differences in nuclear cataract rather than cortical or posterior subcapsular cataract – the three major classifications of age-related cataracts. [85] However, this article and a second meta-analysis reporting on clinical trials of alpha-tocopherol supplementation reported no statistically significant change to risk of ARC when compared to placebo.

Upon reaching the liver, RRR-alpha-tocopherol is preferentially taken up by alpha-tocopherol transfer protein (α-TTP). All other forms are degraded to 2'-carboxethyl-6-hydroxychromane (CEHC), a process that involves truncating the phytic tail of the molecule, then either sulfated or glycuronidated. This renders the molecules water-soluble and leads to excretion via urine. Alpha-tocopherol is also degraded by the same process, to 2,5,7,8-tetramethyl-2-(2'-carboxyethyl)-6-hydroxychromane (α-CEHC), but more slowly because it is partially protected by α-TTP. Large intakes of α-tocopherol result in increased urinary α-CEHC, so this appears to be a means of disposing of excess vitamin E. [3] [15] Dreher D, Junod AF.

The Japan National Institute of Health and Nutrition set adult AIs at 6.5mg/day (females) and 7.0mg/day (males), and 650–700mg/day (females), and 750–900mg/day (males) for upper limits, amounts depending on age. [41] India recommends an intake of 8–10mg/day and does not set an upper limit. [42] The World Health Organization recommends that adults consume 10mg/day. [5] The United Kingdom is an outlier, in that it recommends 4 mg/day for adult men and 3 mg/day for adult women.

Vitamin E is an essential nutritional element and is the only lipid-soluble, chain-breaking antioxidant that prevents the propagation of free-radical reactions. Not all of the physiological effects of vitamin E are known. Alpha-tocopherol is the most active isomer of vitamin E. Vitamin E protects polyunsaturated fatty acids (PUFAs) within biological membrane and in plasma lipoproteins. Peroxyl radicals react with vitamin E 1,000 times more rapidly than they do with PUFA. Vitamin E protects red blood cells against hemolysis; it stimulates a cofactor in steroid metabolism; inhibits prostaglandin production; and supresses platelet aggregation.

This supplement provides 833% of the DV for vitamin E per serving and contains the other fat-soluble vitamins: A, D, and K. Distribution of vitamin E to tissues, via the lymphatic system, occurs as a lipoprotein complex. High concentrations of vitamin E are found in the adrenals, pituitary, testes and thrombocytes. Chylomicron remnants, containing newly absorbed vitamin E, are taken up by the liver. Vitamin E is secreted from the liver in very low density lipoproteins. Plasma vitamin E concentrations depend upon the secretion of vitamin E from the liver. Saremi A, Arora R. Vitamin E and cardiovascular disease. Am J Ther. 2010 May-Jun;17(3):e56-65. doi:10.1097/MJT.0b013e31819cdc9a The European Food Safety Authority (EFSA) refers to the collective set of information as dietary reference values, with population reference intakes (PRIs) instead of RDAs, and average requirements instead of EARs. AIs and ULs are defined the same as in the United States. For women and men ages 10 and older, the PRIs are set at 11 and 13mg/day, respectively. PRI for pregnancy is 11mg/day, for lactation 11mg/day. For children ages 1–9 years the PRIs increase with age from 6 to 9mg/day. [39] The EFSA used an effect on blood clotting as a safety-critical effect. It identified that no adverse effects were observed in a human trial as 540mg/day, used an uncertainty factor of 2 to get to a suggest an upper limit of half of that, then rounded to 300mg/day.

Potential confounding factors are the form of vitamin E used in prospective studies and the amounts. Synthetic, racemic mixtures of vitamin E isomers are not bioequivalent to natural, non-racemic mixtures, yet are widely used in clinical trials and as dietary supplement ingredients. [82] One review reported a modest increase in cancer risk with vitamin E supplementation while stating that more than 90% of the cited clinical trials used the synthetic, racemic form dl-alpha-tocopherol.

Most people don’t need a vitamin E supplement and can easily meet their needs by following a healthy, well-rounded diet.
