DHA is primarily found in fish, so consider introducing two servings or more of oily fish a week (per the Dietary Guidelines for Americans) to meet baseline omega-3 fatty acid needs. As nutrition scientist Ashley Jordan Ferira, Ph.D., RDN, explains, however, “To reap the full-on benefits of marine omega-3s for brain, heart, and whole-body health, science indicates a higher dose (1 gram plus) of EPA plus DHA each day is where it’s at. That’s like eating seven servings of oily fish a week, mind you.”*
