Is there a certain DHA vs EPA percentage that I should be getting?
As far as DHA versus EPA percentage goes, there are a variety of ratios when it comes to fish oil supplements. Usually it’s two to one EPA:DHA, with the Physicians for Optimal Heart and Brain Health recommending an EPA v.s. DHA ratio of 40/20. Otherwise, the optimal DHA vs EPA percentage really depends on what you’re taking it for. In some cases, it’s more important to get more EPA than DHA and vice versa. For example, regular use, heart health and joint health, to name a few, benefit from higher percentages of EPA, whereas brain and mood health benefit from higher percentages of DHA.
