Overview

Omega-3 fatty acids (EPA and DHA) are essential fats that your body cannot produce on its own. They are primarily found in fatty fish and algae. EPA and DHA play critical roles in brain function, heart health, and controlling inflammation.

Most people in Western diets consume far too many omega-6 fats and not enough omega-3s. This imbalance is one of the reasons we strongly recommended omega-3 supplementation to many of our customers in the physical store.

Potential Benefits

Brain Health

DHA is a major structural component of the brain. Research suggests adequate omega-3 intake supports cognitive function and may benefit mood.

Heart Health

EPA and DHA support healthy triglyceride levels, blood pressure, and overall cardiovascular function.

Inflammation Support

May help promote a healthy inflammatory response throughout the body.

Generally Well Tolerated

High-quality fish oil and algae oil are very safe when taken at recommended doses. Choose third-party tested brands (IFOS 5-star rated).

Typical Dosage
Daily Dose
1–2g
Combined EPA + DHA (not total fish oil weight)
Best Forms
Fish oil or algae oil (for vegans)
Look for IFOS 5-star rated or third-party tested brands
Pro Tips
  • Store in the fridge to prevent oxidation
  • Take with a meal containing fat
  • Choose triglyceride form (not ethyl ester) for better absorption
  • Algae oil is excellent for vegetarians/vegans
Research Snapshot

Decades of research support the cardiovascular and cognitive benefits of EPA and DHA. A 2022 meta-analysis of 28 randomized controlled trials in nearly 137,000 participants found that omega-3 supplementation was associated with a lower risk of major cardiovascular events and cardiac death, though no significant benefit was seen for all-cause mortality.

How Omega-3 Compares

Ingredient Best For Key Difference
Omega-3 (EPA/DHA) Brain, Heart, Inflammation Essential fat; must come from diet/supplements
Turmeric / Curcumin Joint comfort, Inflammation Plant compound; absorption needs enhancement
CoQ10 Heart, Energy, Antioxidant Produced by body; declines with age

Omega-3 pairs extremely well with Vitamin D3 and Magnesium.

Frequently Asked Questions
Fish oil or algae oil — which is better?
Both are excellent. Fish oil is generally more affordable and has more research behind it. Algae oil is the best choice for vegetarians and vegans, and it’s also more sustainable.
Will omega-3 make me smell fishy?
High-quality, fresh fish oil should not cause fishy burps. If it does, the product may be oxidized or low quality. Choose reputable brands and store in the fridge.
How long until I notice benefits?
Some benefits (like reduced inflammation markers) can appear within a few weeks. Brain and mood benefits often take 8–12 weeks of consistent use to become noticeable.
