    Product Description

    α-Linolenic acid is an essential ω-3 polyunsaturated fatty acid found in plants.1 In vivo, it is converted to the longer-chain fatty acids eicosapentaenoic (Item Nos. 90110 | 90110.1 | 21908), docosapentaenoic (Item Nos. 90165 | 21907), and docosahexaenoic acid (Item No. 90310).2 It is also catabolized via fatty acid β-oxidation for energy or the synthesis of saturated and monounsaturated fatty acids, or stored in adipose tissue. Dietary consumption of α-linolenic acid-containing foods is positively associated with a moderately lower risk of cardiovascular disease.1

    WARNING This product is not for human or veterinary use.
