Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Flax (Linum usitatissimum), particularly flaxseed, is sometimes used to support menopausal symptoms due to its content of phytoestrogens, specifically lignans. Phytoestrogens are plant-derived compounds that can mimic or modulate the body's estrogen, which declines during menopause, leading to symptoms such as hot flashes and night sweats. Some small clinical studies have investigated flaxseed supplementation for menopause. For example, a few trials have suggested modest reductions in hot flash frequency and intensity when consuming flaxseed compared to placebo or baseline. However, results are inconsistent; other studies have found no significant benefit over placebo. A 2013 systematic review published in "Menopause" concluded that there is insufficient evidence to recommend flaxseed for the alleviation of menopausal symptoms, citing variability in study designs, dosing, and outcomes.

Overall, the scientific evidence supporting flaxseed for menopause is limited and mixed. While there is a plausible biological mechanism due to the lignans’ weak estrogenic activity, the clinical impact appears to be small or uncertain. Flaxseed is generally safe for most people when consumed as part of the diet, but its use as a treatment for menopausal symptoms should be considered experimental until more robust evidence emerges.
