Can I take krill oil and cod liver oil together safely?

Yes. Both krill and cod liver oil are excellent sources of essential fatty acids EPA and DHA. Cod Liver Oil also contains Vitamins A and D. Krill oil may be more readily absorbed and is an excellent source of astaxanthin. It is safe to take these together. One would have to take very large amounts for either or both to be hazardous.
