Vitamin E is present in these capsules because it is a natural, fat-soluble compound found in pumpkin seed oil; it is not a separately added ingredient. Its role is that of an antioxidant. In practical terms, this means it helps protect the oil's own fatty acids and other lipids in the body from oxidative stress—a natural process where unstable molecules (free radicals) can cause damage. It's important to understand that the vitamin E here supports the stability and nutritional value of the oil itself. The product is a food supplement, and its purpose is to provide fatty acids as part of your diet. Vitamin E contributes to this purpose by helping to maintain the integrity of those nutrients. It is not a multivitamin and is not intended to address a standalone vitamin E deficiency.
