1. Start Here: Serving size is the amount of fish oil necessary to receive the EPA and DHA dose listed. Higher potency fish oils contain more EPA and DHA in fewer capsules or spoonfuls.
2. Check for Antioxidants: Antioxidants help preserve fish oil purity and freshness, and protect our cells from free-radical damage.
3. Look at the Omega-3 Totals: Omega-3s should be the most prevalent form of fatty acids in each dose because they're the most beneficial for our body.
4. Add the EPA and DHA Levels: Quality supplements should contain substantial amounts of EPA and DHA.
5. Fish Oil Form: There are three forms of marine oils - natural triglyceride (TG), ethyl ester (EE), and re-esterified triglyceride (rTG).
6. Confirm Testing: Make sure the product is tested for freshness, potency, and purity and that it's low in contaminants and heavy metals.
