Lecithin is a mixture of phosphatides found in all plants and animals. KAL Lecithin 1200 mg from soy bean oil typically contains a high percentage of linoleic acid (660 mg) with lesser amounts of palmitic (192 mg), oleic (204 mg), stearic (60 mg), linolenic (84 mg) and other fatty acids, choline, inositol and phosphorous. These substances are present together in the form of phosphatides (or phospholipids). Regional differences in soil and growing conditions affect lecithin content among soy crops. KAL Lecithin is made from the highest quality liquid lecithin available. KAL guarantees that Lecithin softgels will contain liquid lecithin with an average concentration of 61% insoluble soy phosphatides.
