Vitamin E – Tocopherols
Vitamin E is a fat soluble vitamin composed of a group of compounds called tocopherol and tocotrienol compounds that exhibit the biological activity of alpha-tocopherol.
Seven forms exist in nature: Alpha-tocopherol, 100; Beta-tocopherol, 50; Gamma-tocopherol, 10–30; and Delta-tocopherol, 1.
Alpha tocopherols have the greatest biological value
Antioxidant – protects fatty acids against oxidation and helps rid toxic substances from the body.
Vitamin E is absorbed in the intestine in the presence of fat and should be taken with food that contains fat or it may not be absorbed properly.

The female hormone oestrogen is a vitamin E antagonist.
