Tyrosol
Also known as: tyrosol phenol, p-tyrosol, 4-hydroxyphenethyl alcohol
Tyrosol is a simple polyphenol found in Rhodiola rosea, red wine, and olives that acts as a free-radical scavenger. Human evidence for isolated tyrosol is extremely limited; benefits are largely inferred from Rhodiola extract research.
