Five drops a day of pomegranate seed oil, added to a Mediterranean diet, was linked to better cognition in a one-year randomized trial of 80 people with mild cognitive impairment.

Here is what the oil actually is, how it differs from juice and urolithin A, who might consider it, and why the results are promising but not proof.
