“Omega-3 fatty acids can are available a wide range of varieties, however typically, we’re most aware of EPA [eicosapentaenoic acid] and DHA [docosahexaenoic acid],” says Kasey Hutchinson, RDN, a Montana-based registered dietitian. “Analysis exhibits that krill oil is barely higher in omega-3 fatty acids [compared to fish oil].”

Price
