Mechanism of action

1

Antioxidant vitamin E activity

Once delivered, alpha-tocopherol protects cell membranes from lipid peroxidation as the body's main fat-soluble antioxidant.

2

Micelle-forming absorption

The polyethylene glycol portion makes vitamin E water-dispersible, forming micelles that improve uptake of fat-soluble nutrients.
