Note the very modest resveratrol content of these food sources. While getting antioxidants and polyphenols from food is always a good thing, those looking for a clinically relevant (and targeted, daily) dose of resveratrol may want to consider supplementation.
Nutrition scientist Ashley Jordan Ferira, Ph.D, RDN explains that, “A meaningful dose of resveratrol for health is about 75 milligrams and up. From targeted brain health research, we know that benefits for cerebral blood flow, verbal memory, and cognitive performance are observed at 150 milligrams of daily resveratrol.”*
Wearing her dietitian hat, Feria puts this into perspective with our daily diet: “Want to eat or drink your way to 150 milligrams of resveratrol? That’ll be 21 cups of mulberries or 300 glasses of wine.” Or, “have your berries and supplement, too. They are both helpful and healthful. The latter is just way more targeted and concentrated resveratrol source for functional brain health gains,”* she concludes.
