Those who don't routinely eat fish should supplement with fish oils to enjoy the benefits of nature's best fats, DHA and EPA. Dr. Bob's Daily Fish Oil blends the two, DHA and EPA. DHA is the fat which helps keep cellular membranes more healthy and is one of the most abundant fats in the brain. EPA provides anti-inflammatory benefits to the body and brain. Dr. Bob's Daily Fish Oil is custom made with Dr. Bob Sears in the USA.
