Understanding Omega-3: EPA, DHA and DPA
Learn how to read marine-oil labels and compare fish oil with seal-oil formulas.
By Ideal Health Inc. · Updated October 23, 2026
Start with the fatty acids.
Omega-3s are a family of fats. ALA is found in foods such as flaxseed, while fish oils commonly provide EPA and DHA. DHA is an important component of cell membranes, including those in the brain and retina. DPA is another long-chain omega-3 listed in some marine-oil formulas.
Compare amounts, not just oil weight.
The total oil amount is different from the amount of EPA and DHA. A softgel labelled “1000 mg fish oil” does not necessarily contain 1000 mg of these omega-3s. Check the ingredient amounts, serving size and daily directions together.
Fish oil or seal oil?
Our Super Omega 3+ uses fish oil, while Newfoundland Harp Seal Oil supplies EPA, DHA and DPA from natural harp seal oil. Balance Omega+ combines fish oil with CoQ10, lutein and vitamins A and E. These are different formulas; one should not be assumed to suit everyone better.
