cent study from the University of Oxford found that supplementation of 600 milligrams of omega-3s, and DHA (docosahexaenoic acid) in particular, was associated with longer sleep duration—58 minutes of more sleep per night—in a subset of children, compared to placebo.

Omega-3s are important for women who are pregnant or nursing. DHA is a building block of a baby’s brain. In fact, 97 percent of the omega-3s found in the brain is DHA. A vegetarian and sustainable source of DHA from algae can be found in supplement form. Look for the life’sDHA logo on the packaging to know you are getting a vegetarian source.

gum disease, diabetes, insulin resistance, arthritis, multiple sclerosis, hypertension, and certain cancers, including colon, breast, pancreas and prostate cancers.

5. Vitamin E. Vitamin E functions as the main fat-soluble antioxidant, protecting cells, tissues and organs from damage. It also contributes to healthy blood flow by regulating the opening of blood vessels and preventing cholesterol from building up on blood vessel walls. The research continues to show other roles for this essential nutrient, such as a recent study that showed vitamin E may positively impact functional performance among participants with mild to moderate Alzheimer’s disease.
