The Importance of DHA Throughout the Lifecycle
DHA omega-3 is important for health and development throughout the lifecycle. Numerous scientific studies confirm that everyone, from infants to adults, benefits from an adequate supply of DHA in the diet.
For Mothers-to-be, DHA Supports a Healthy Pregnancy
Maternal DHA supplementation during pregnancy and nursing significantly enhances the level of DHA available to the fetus and infant and may improve developmental outcomes, such as improved eye-hand coordination, motor skills and attention spans. DHA has also been shown to play a part in maternal well-being. One study showed that maternal DHA supplementation increased the length of pregnancy by 6 days helping mothers carry to a healthy or full term. Additionally, some research suggests that adequate levels of DHA in the maternal diet may play a role in helping a mother’s emotional well-being after birth.
For Infants and Toddlers, DHA is Important for Brain and Eye Development
Certain studies (some, but not all studies) have shown that infants who either received DHA during gestation or DHA (and ARA) during the first year of life exhibited improved mental development and better visual acuity, and have significantly lower blood pressure. Young children who received DHA supplementation exhibited a range of advantages over those who did not receive DHA supplementation, including improved vision and improved blood vessel function specifically in children with high cholesterol levels.
For Adults, DHA Supports Brain, Eye and Heart Health
A growing body of research continues to support the role that DHA plays in maintaining good health throughout the lifecycle. DHA is the major structural fat in the brain and eyes accounting for up to 97% of the omega-3 fatty acids in the brain and up to 93% of the omega-3 fatty acids in the retina. Studies have shown that DHA is necessary for the optimal structure and function of nerve cells in the brain and eyes. Low levels of DHA have been associated with the increased risk for a variety of neurological disorders. Additionally, a scientific review on DHA stressed the significant role that DHA plays in the maintenance of normal neurological function. DHA is also a key component of the heart and one of the omega-3 fats recommended by the American Heart Association and USDA Dietary Guidelines for good cardiovascular health.
