Peat Archive

Ray Peat considered vitamin E one of the most important protective nutrients, primarily because of its ability to prevent lipid peroxidation of polyunsaturated fats. Since modern diets contain far more PUFAs than historically, the need for vitamin E is correspondingly greater. Peat viewed vitamin E as working synergistically with thyroid hormone, progesterone, and aspirin to maintain cellular respiration and oppose the inflammatory cascade.

Peat recommended alpha-tocopherol as the primary form of vitamin E, typically 100-400 IU daily, and noted that it is best taken with food containing some fat. He emphasized that vitamin E protects against estrogen's effects, reduces lipid peroxidation, and supports fertility in both sexes — which is why it was originally called the 'anti-sterility vitamin.'
