Choosing The Best Omega-3 Supplement

With so many omega-3 and fish oil supplements and fortified foods, making the right choice can be tricky. These guidelines can help.

• Avoid products that don’t list the source of their omega-3s. Does the package list the source of omega-3 fatty acids? If not, chances are it’s ALA (sometimes from plain old canola or soybean oil), which most Westerners already get plenty of.
• Don’t fall for fortified foods. Many fortified foods (such as margarine, eggs, and milk) claim to be high in omega-3 fatty acids, but often, the real amount of omega-3 is miniscule. 
• Look for the total amount of EPA and DHA on the label. The bottle may say 1,000 milligrams of fish oil, but it’s the amount of omega-3 that matters. Read the small print. It may show only 300 mg of EPA and DHA (sometimes listed as “omega-3 fatty acids”), which means you’d have to take three capsules to get close to 1,000 milligrams of omega-3.
• Choose supplements that are mercury-free, pharmaceutical grade and molecularly distilled.Make sure the supplement contains both DHA and EPA. They may be hard to find, but supplements with higher concentrations of EPA are better.

Fish oil supplements can cause stomach upset and belching, especially when you first start taking them. To reduce these side effects, take them with food. You may also want to start with a low dose and gradually increase it, or divide the dose among your three meals.
