Vitamin E is a fat-soluble antioxidant that protects cell membranes from oxidative damage. The brain's high lipid content makes it particularly susceptible to oxidative stress. Research has explored vitamin E's potential role in supporting brain health, primarily through its alpha-tocopherol form.

What dosage of Vitamin E has been used in cognitive studies?

Cognitive studies have used doses ranging from 400 IU to 2,000 IU of alpha-tocopherol daily. Mixed tocopherol formulations including gamma-tocopherol are also available. The tolerable upper intake is 1,000 mg (approximately 1,500 IU) per day. Consult your healthcare provider before high-dose use.

About

Vitamin E is a fat-soluble antioxidant that protects neuronal membranes from lipid peroxidation. High-dose vitamin E may slow functional decline in moderate Alzheimer's disease, though evidence for prevention is mixed.

How It Works

Fat-soluble antioxidant protecting polyunsaturated fatty acids in neuronal membranes; supports mitochondrial membrane integrity; alpha-tocopherol is the primary brain-active form.
