Pharma Nord's magnesium salts of fatty acids are produced in an industrial process where stearic acid is chemically bonded to magnesium oxide.
The source of stearic acid is vegetable and it is based on palm oil (not RSPO). In general, stearic acid can also be produced from either cottonseed oil or coconut oil. Vegetable stearic acid is produced by hydrogenation of vegetable oil. Stearic acid does not adversely affect the body's cholesterol balance.
