This is common because resveratrol is sometimes described as “phytoestrogen-like.” Mechanistic research suggests it can interact with estrogen receptors, but that does not equal a guaranteed increase in estrogen levels.\n\nHormone balance depends on many factors (age, body fat, liver metabolism, microbiome, thyroid function, medications). Any effect may vary by dose, duration, and individual biology, and most people should not expect a clear clinical estrogen rise.\n\nCaution groups include hormone-sensitive cancer history, endometriosis, and those on hormonal therapies—professional guidance is recommended.\n\nBottom line: it may interact with estrogen pathways, but “it increases estrogen” is an oversimplification.
