The best source for Omega-3 is oily marine fish, which contain both EPA and DHA. Most algae sources are less complete because they only provides you with DHA and very small quantities of EPA, if any at all.

Fish oil is more natural than algae as it is caught from the ocean and not grown in fermentation labs. It is considered the best source of Omega-3 because there are more than 20,000 studies supporting the health benefits of fish oil and consumers trust the benefits.

Buyer beware! The best source for Omega-3 is oily marine fish, which contain both EPA and DHA, or fish oil supplements and enriched foods with added Omega-3 EPA/DHA. Not all Omega-3 claimed on food labels is EPA and DHA, as such, always look for Omega-3 EPA+DHA from fish oil on the label of Omega-3-enriched food products.
