A nutritionally complete diet includes omega-3s such as Martek life's DHA. DHA (docosahexaenoic acid), an omega-3 fatty acid, is a major structural fatty acid in the brain and eyes, and is a key component of the heart. DHA is the only omega-3 that has been shown to support brain, eye and heart health throughout every stage of life.* Yet the typical American diet usually falls short of recommended DHA levels. Martek Life's DHA softgels are encapsulated in a vegetarian capsule making them 100% vegetarian. Unlike other sources of DHA omega-3, Martek life's DHA comes from a vegetarian source (algae). Because Martek Life's DHA is not from fish, there is no worry of ocean-borne contaminants. From start to finish, Martek Life's DHA is produced in an FDA-inspected facility with controls in place to ensure the highest quality product.
