Fat-Soluble Vitamin F

By Cat, June 2019

Vitamin F is another name for essential fatty acids; see my post: Essential Fatty Acids: A Case of Balance for more about these essential fatty acids.

Early in the research of Dr. Weston A. Price, he discovered a substance he called the X-Factor in good quality butter and butter oil, that he found to be essential for good health. Later the X-Factor was believed to be a member of the Vitamin F family, but has since been identified as Vitamin K2. See my article on Vitamin K for more.
