DHA (docosahexaenoic acid) omega-3 is a long-chain omega-3 fatty acid that
serves as a primary building block for the brain and the eyes and supports
brain, eye and cardiovascular health throughout life. There is a large and
growing body of scientific evidence demonstrating that people of all ages, from
infants to aging adults, benefit from an adequate supply of DHA omega-3 in the
diet. Scientific reviews highlight the importance of DHA omega-3 in proper brain
and eye development and function. Yet despite its importance, Americans have
among the lowest dietary intakes of DHA omega-3 in the world.

Fish are often incorrectly thought to be the only source of DHA omega-3.
However, life’sDHA offers a trusted, vegetarian form of algal DHA that contains
no oceanic pollutants and toxins. Fish are an abundant source of DHA because of
the DHA-rich microalgae in their food chain; life’sDHA is derived from
microalgae and produced in an FDA-inspected facility, from start to finish,
using a sustainable source that does not deplete ocean resources. life’sDHA is
found in numerous foods, beverages and supplements for people of all ages. It is
also the only source of DHA used in U.S. infant formula and is available in more
than 95 percent of the formulas on the U.S. market.
