How many studies support Berries?

Most of the available literature for this topic centers on resveratrol, a polyphenol found in berries (and grapes), covering effects on health, skin, and bone density, including one randomized trial showing improved bone mineral density in postmenopausal women. That's backed by 4 published studies in Vitaebase's database, including 1 randomized controlled trial and 3 meta-analyses, the most recent from 2023 -- a modest but real research base.
