Omega 3 fatty acids are essential- your body can't make them, so you have to get them from food or supplementation. EPA and DHA specifically support brain health, cardiovascular function, joint health, inflammation regulation, and skin barrier integrity. Most people are chronically under-dosed on both.
This one delivers 3600mg of fish oil with over 2100mg of actual omega-3 fatty acids per serving- 1300mg EPA and 860mg DHA. Wild caught, burpless formula, and no unnecessary fillers. If you're going to supplement omega 3 make sure the EPA and DHA numbers are actually on the label. A lot of fish oil products bury those numbers because they're low.
