Vegetarian DHA, sustainably sourced from algae, provides 570 mg of the beneficial omega-3 DHA in a single serving. The omega-3 DHA is an essential nutrient for optimal health. But a vegetarian diet may not provide an adequate amount of DHA, which is why a plant-based supplement can be a great option. DHA is important for people of all ages to support mood and overall health. And it's especially important for women who are pregnant or nursing, as it promotes healthy brain and vision development in growing children. Vegetarian DHA is tested by an FDA-registered laboratory for freshness, potency, and purity.
