Hello there!
The vitamin that the client was describing was Vitamin E
Vitamin E is considered "the vitamin of youth". It protects tissues from free radicals, decreasing the cellular oxidative damage, that can affect the integrity of tissues in the body.
Vitamin E can oxidate in the body, acting as a sort of "bodyguard" for other substances because it oxidates instead of polyunsaturated fats and other fat-soluble substances like vitamin A. It also assists in the formation of red cells in the blood and helps in the synthesis of prostanoids (important compounds in reproductive processes).
