Overview

Omega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), are crucial for cardiovascular health. The triglyceride (TG) form is the molecular structure found naturally in fish. It is considered more stable and bioavailable than the more common ethyl ester (EE) form found in many supplements. Re-esterified triglyceride (rTG) is a concentrated form that has been converted back to the TG structure for superior absorption.

Key Benefits

Lowers Triglycerides

High doses of omega-3s are FDA-approved for lowering very high triglyceride levels.

Reduces Inflammation

EPA and DHA are precursors to anti-inflammatory signaling molecules, helping to balance the body's inflammatory response.

Supports Brain Health

DHA is a major structural component of the brain and retina, crucial for cognitive function and development.

Dosage & How to Take

1-3 grams of combined EPA and DHA daily for general health.
