Role in the formula: Plant polyphenol support
Oleuropein is a polyphenol concentrated in olive leaves. Scientific literature often focuses on antioxidant capacity and cardiovascular-related markers rather than memory scores.
Phytomem One lists oleuropein among its named botanicals, positioning olive-leaf chemistry next to saffron and the marine extracts.
As with every ingredient here, published research on isolated oleuropein is not the same as a clinical trial of Phytomem One.
Practical caution: Olive allergy is a reason to skip this formula until you speak with a clinician.
Individual milligram amounts for Oleuropein (Olive Leaf) inside Phytomem One are not published on the materials we reviewed. Always read the bottle label you receive.
