Description
Curator's Comment: description was created based on several sources, including https://www.hsph.harvard.edu/nutritionsource/omega-3-fats/ | https://www.ncbi.nlm.nih.gov/pubmed/24352849 | https://www.fda.gov/Cosmetics/ProductsIngredients/Products/ucm134064.htm

Doconexent (Docosahexaenoic acid, DHA) is an omega-3 fatty acid that is a primary structural component of the human brain, cerebral cortex, skin, and retina. DHA is widely used as a food supplement, and is beleived to support healthy brain development in young childred, prevent cardiovascular disease and cognitive decline during Alzheimer's disease. Most of these claims, however, were not supported by clinical trials. DHA spray is used as a tanner.
