Omega-3 Go-To Guide
A physician's 5-page guide to fish oil: what EPA and DHA do, how to read a label, what quality looks like, and when to be cautious, with 15 sources.
Most people take fish oil without ever asking what it’s doing. This guide answers your questions in plain language, so you can decide whether omega-3s belong in your wellness plan and, if they do, how to choose the best product for you. It is the companion to the three-part omega-3 series of The Aslan Health Podcast.
What is inside
Definitions for the twelve terms that matter most, including ALA, EPA, DHA, the omega-3 index, and third-party testing.
What EPA and DHA do in your cells, and a food-first foundation built on fatty fish about twice a week.
A seven-row do’s and don’ts table, and a label-reading reset that shows why "1000 mg fish oil" on the front of a bottle may mean only 300 mg of EPA plus DHA.
A quality and freshness checklist, and a safety section covering allergies, bleeding risk, heart rhythm, pregnancy, and surgery.
A seven-step stewardship plan you can actually follow.
The guide draws on the NIH Office of Dietary Supplements, the American Heart Association’s science advisories, the FDA and EPA advice about eating fish, and the GOED oxidation standards, with 15 sources listed in full.
Fish oil is generally well tolerated, but higher doses are not automatically safe for everyone. Talk with your clinician first if you have a fish or shellfish allergy, a bleeding disorder, very high triglycerides, a heart rhythm problem, liver disease, or surgery ahead; if you are pregnant or breastfeeding; or if you take a blood thinner, an antiplatelet medication, or several medications.
Products: the Aslan Health Fullscript storefront and the Omega-3, Fish Oil protocol, where the products in the Omega-3 Protocol & Product Guide are listed.
Aslan Health earns a commission on purchases made through the dispensary. Your price is the same either way, and it does not change what is recommended here.
