What is Omega-3 Fish Oil?

Omega-3 fish oil delivers EPA and DHA, the two long-chain omega-3 fatty acids your brain, heart, joints, and inflammation pathways depend on. The triglyceride form used by premium brands like Sports Research is more bioavailable and stable than the ethyl ester form found in cheap supplements. Decades of research support omega-3s for cardiovascular function, mood, joint comfort, and recovery from physical stress. The American Heart Association recommends 1-2 g of combined EPA+DHA daily for general health and 2-4 g for cardiovascular support. Always store fish oil refrigerated and check the lot's third-party purity testing before buying.

WHY IT MATTERS
