Black currant (Ribes nigrum) seed oil accommodates alpha and gamma-linolenic acid, anthocyanins, proanthocyanidin, flavonoids, vitamin C, and a pair of nitrile-containing compounds. It is generally properly tolerated. Some evidence exists that indicated supplementation of mothers with black currant seed oil throughout pregnancy and exclusive breastfeeding decreases the rate of atopic dermatitis in breastfed infants. Dietary supplements don’t require extensive pre-marketing approval from the U.S. Food and Drug Administration. Manufacturers are accountable to ensure the safety, but do not have to show the safety and effectiveness of dietary supplements before they’re marketed. Dietary supplements may contain a number of elements, and differences are sometimes found between labeled and actual ingredients or their quantities. A producer may contract with an independent group to confirm the quality of a product or its substances, however that does not certify the safety or effectiveness of a product. Due to the above points, clinical testing outcomes on one product will not be applicable to other products. More detailed details about dietary supplements is available elsewhere on the LactMed Web site.
