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 specific, daily) dose of resveratrol may want to consider supplementation.
nutrition scientist Ashley Jordan Ferira, PhD, RDN explains that, “A significant dose of resveratrol for health is approximately 75 milligrams and higher. From research specific to brain health, we know that benefits to cerebral blood flow, verbal memory, and cognitive performance are seen with 150 milligrams of resveratrol daily.”*
Wearing her dietitian hat, Feria puts this into perspective with our daily diet: “Do you want to eat or drink to get to 150 milligrams of resveratrol? That will be 21 cups of blackberries or 300 glasses of wine.” Or, “Take your berries and your supplement too. Both are helpful and healthy. The latter is a much more targeted and concentrated source of resveratrol for functional gains in brain health,” *she concludes.
