What’s in your omega-3 supplements?
When it comes to omega-3 supplements, not all products are created in equal. The quality of the product can impact your experience. At times there’s been controversy about label claims, in fact one published study of products sold in the United States found more than half of the omega-3 oils tested did not meet their label claims1.
Why omega-3 purity matters
Why is purity so important? For starters, the world’s oceans have become polluted, as have populations of fish and other sea life—which are often the source for omega-3 supplements. Purity is vital when choosing a fish oil supplement, to ensure it doesn’t contain unwanted pollutants or heavy metals.
Don’t forget about potency
When it comes to health benefits from omega-3, it's the EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) that matter most. Derived from marine-based sources, such as fish and algae, they are vital nutritional support for the maintenance of good health throughout life2,3. It can be tempting to choose a seemingly more affordable product with a high amount of omega-3, but low amount of EPA and DHA. When it comes to potency, however, it’s often a case of “you get what you pay for.” Work with your health care provider to determine the right amount of EPA and DHA for the benefit you’re looking to achieve.
