DHA (docosahexaenoic acid) is an omega-3 fatty acid that forms a large share of the structural fat in the human brain and retina.
Research links adequate DHA intake in infancy and early childhood to healthy visual and cognitive development, which is why global health bodies recommend DHA for pregnant and lactating mothers.
Most DHA comes from fish oil. Ours is algal — grown from the same algae fish eat — so it is 100% vegetarian, mercury-free and gentle enough for little stomachs.
