|Cell membranes need lipids and sterols to stay healthy. Unfortunately, grain processing strips lipids, sterols, and other vital nutrients from the foods that make up our dietary staples. Tre-en-en Grain Concentrates help assure good nutrition at the cellular level by providing a unique and exclusive blend of whole-food extracts from wheat germ, rice bran, and soybeans. Developed and introduced by GNLD in 1958, Tre-en-en was the world's first phytonutrient supplement. It provides phyto-LIPIDS essential to optimal health and cellular function, including omega-6 and omega-3 fatty acids, and phyto-STEROLS, including beta-sitosterol, gamma-oryzanol, stimasterol, and campesterol, plus octacosanol.
