Fish oil is extracted from the tissues of oily fish and serves as the primary natural delivery vehicle for EPA and DHA. While pharmaceutical-grade isolates of EPA/DHA exist, standard fish oil provides a natural matrix of these fatty acids that has been shown to improve lipid profiles, reduce resting blood pressure, and alleviate joint stiffness.

Clinical Summary

One of the most studied dietary supplements globally. Carries strong evidence for reducing triglycerides, alleviating joint stiffness in rheumatoid arthritis, and supporting overall cardiometabolic health.

Dosage Guidelines

1,000mg to 4,000mg of total fish oil daily, depending on the specific EPA/DHA yield.

Safety & Side Effects

Gastrointestinal discomfort, nausea, and fishy eructation (burps).

Known Interactions

High doses interact with anticoagulants and blood pressure medications.
