However, on the back, you\u2019ll read that EPA and DHA are only 320 mg.<\/li>\n<li><strong>Form of omega-3:<\/strong> For better absorption, look for FFA (free fatty acids), TG, rTG (triglycerides and reformed triglycerides), and PLs (phospholipids) rather than EE (ethyl esters).<\/li>\n<li><strong>Purity and authenticity:<\/strong> Try to buy products that have a third-party seal. These labels show that they\u2019re safe and contain what they say they do.<\/li>\n<li><strong>Freshness:<\/strong> Omega-3s are prone to going rancid. Once they go bad, they\u2019ll have a foul smell and become less potent or even harmful. Always check the date, smell the product, and see if it contains an antioxidant like vitamin E.<\/li>\n<li><strong>Sustainability:<\/strong> Try to buy fish oil certified by the MSC, the Environmental Defense Fund, or a similar organization.
