Algal Oil (Vegan DHA)
Plant-based omega-3 from microalgae. Vegan source of preformed DHA and sometimes EPA.
Cod Liver Oil
Traditional omega-3 source also providing vitamins A and D. Good winter supplement but watch vitamin A intake.
EPA (Eicosapentaenoic Acid)
EPA is a long-chain omega-3 polyunsaturated fatty acid with strong evidence supporting cardiovascular and inflammatory benefits. It is commonly used for heart health, triglyceride reduction, and cognitive support.
Fish Oil (EPA/DHA)
Marine omega-3s with cardiovascular, brain, and anti-inflammatory benefits. EPA and DHA are the bioactive forms.
Flaxseed Oil (ALA)
Plant-based omega-3 (ALA) that requires conversion to EPA/DHA. Conversion is inefficient (5-15%). Better than nothing for vegans.
GLA (Borage Oil)
Highest GLA content of any plant oil. More concentrated than evening primrose for skin and inflammation.
