Ultra Omega

Who it suits: athletes who train hard, anyone who needs a higher dose for heart, blood vessels and joints, and people who'd rather take fewer capsules. The best form is re-esterified triglyceride (rTG), which absorbs better than the ethyl-ester (EE) form.

How to choose: look for the EPA and DHA amounts rather than "fish oil 1,000 mg", a purity certificate such as IFOS, and freshness. Take with food. Check with a doctor before going above 3 g of EPA + DHA a day or combining it with blood thinners.
