Vitamin E (Tocopherols)

Vitamin E has significant biological activity in the human body.  As a powerful antioxidant, it acts as a peroxyl radical scavenger, preventing the propagation of free radicals in bodily tissues. Indeed, by virtue of it's fat solubility, it readily incorporates into the cell membrane to counteract the process of lipid oxidation. 

Other functions include roles in enzymatic activities, regulation of gene expression, neurological processes, and tissue regeneration.

(Please note: since vitamin E requirements are dependent on PUFA intake, which varies widely, RI values have not been published. The table below provides estimated upper intake levels)

Deficiency of vitamin E may result in myopathy (muscle weakness), neurological impairment (manifesting as peripheral neuropathy or ataxia), and damage to the retina of the eye (retinopathy). 

As vitamin E can act as an anticoagulant, increasing the risk of excessive bleeding, hypervitaminosis in combination with anticoagulant agents such as aspirin, could be life threatening. For this reason, upper intake levels have been specified by health authorities. Furthermore, hypervitaminosis E may also counteract the absorption of vitamin K, leading to vitamin K deficiency.

If you are concerned about your vitamin D intake, please consult your healthpro specialist dietitian or visit your local GP.
