Omega-3 Fish Oil (EPA/DHA)

Reviewed by the Nimbera editorial team · Last updated May 2026

A 2022 controlled animal study found that omega-3 supplementation combined with exercise reduced markers of collagenase-induced Achilles tendinopathy, and omega-3s are established modulators of inflammation - though robust human tendinopathy trials are still limited.$15-$35 per month

How to use

Take 1-3 g per day of combined EPA and DHA from a quality fish oil (or algae oil if vegetarian), with food to improve absorption and reduce aftertaste. Use as a supportive anti-inflammatory adjunct alongside a loading program. Give it 8-12 weeks for any benefit to accrue.

How it works

EPA and DHA are converted into specialized pro-resolving mediators (resolvins, protectins) that actively resolve inflammation, and they shift the balance away from pro-inflammatory eicosanoids. This may calm the low-grade inflammation associated with chronic tendon pain and support a healthier healing environment.

Where to buy

Pharmacies, supermarkets, and online. Reputable brands include Nordic Naturals Ultimate Omega, Carlson Elite Omega-3, and Nature Made Fish Oil; Nordic Naturals Algae Omega for a vegan option.

Typical cost: $15-$35 per month

Safety notes

High doses (over 3 g/day) can thin the blood - use caution if on anticoagulants or before surgery, and check with your doctor. May cause fishy burps, reflux, or loose stools. Choose third-party tested (IFOS/USP) products to avoid rancidity and heavy-metal contamination. Human evidence for tendon repair specifically is still preliminary.

  • Interactions can occur with prescription medications, blood thinners, and immunosuppressants.
  • Herbal remedies can affect how the body absorbs or metabolises drugs.
  • Check drugs.com interactions checker before starting.
