What is the recommended dosage for Omega-3 Fatty Acids (EPA/DHA)?

General: 250-500 mg combined EPA/DHA/day; Anti Inflammatory: 1,000-3,000 mg combined EPA/DHA/day

What are the side effects of Omega-3 Fatty Acids (EPA/DHA)?

Potential side effects include: Fishy aftertaste and burping, Gastrointestinal discomfort (nausea, diarrhea), Increased bleeding risk at high doses, Potential LDL cholesterol increase at very high doses.

What is omega-3 and how does it support immune function?

Omega-3 fatty acids (EPA and DHA) are essential polyunsaturated fats found in fish oil and algae. They play a role in resolving inflammation through specialized pro-resolving mediators (SPMs) and have been studied for their effects on immune cell membrane function.

What dosage of omega-3 has been studied for immune-related outcomes?

Clinical trials have used omega-3 doses of 1–4 g per day of combined EPA and DHA. For immune and anti-inflammatory outcomes, doses of 2–3 g per day are common, typically studied over periods of 8 to 16 weeks.

What are the potential side effects of omega-3 supplementation?

Common side effects include fishy aftertaste, burping, and mild gastrointestinal effects. High doses (above 3 g per day) may increase bleeding risk and should be discussed with a healthcare provider, especially before surgery or if taking anticoagulants.

About

EPA and DHA alter cell membrane phospholipid composition and give rise to specialized pro-resolving mediators (resolvins, protectins, maresins) that actively resolve inflammation. The VITAL trial showed a 15% reduction in autoimmune disease risk. DHA showed stronger anti-inflammatory effects than EPA in randomized studies.

How It Works

EPA and DHA alter cell membrane phospholipid composition and give rise to specialized pro-resolving mediators (resolvins, protectins, maresins); EPA inhibits NF-kB activation; DHA suppresses pro-inflammatory gene expression.
