Vitamin E

A fat-soluble antioxidant that protects cell membranes.

~90% of Americans do not meet the estimated average requirement for vitamin E from food

Why it matters for longevity

Vitamin E protects polyunsaturated fatty acids in cell membranes from oxidative damage, supports immune function, and helps prevent LDL cholesterol oxidation. The alpha-tocopherol form is the most biologically active. Research from the Women's Health Study found that vitamin E supplementation reduced cardiovascular death by 24% in women over 10 years of follow-up.
