Doctor?s Best Krill naturally contains phospholipids and astaxanthin. We have also added omega-3 DHA and EPA. These vital lipids are building blocks for the cell membrane systems that manage the important life functions in all our organs. According to studies the more omega-3s in the diet the healthier the heart will be. DHA is the most common fatty acid in the human brain. High DHA and phospholipids help support both heart and brain function. The phospholipids in omega 3 fatty acids are easily blended in stomach fluids and gentle in the stomach.* At Doctor?s Best we lead with science.
