Studied Dose Commonly around 30 to 54 mg of genistein per day.
Active Compound Genistein, a purified soy isoflavone (aglycone form).

Benefits

Bone metabolism

In a randomized trial in osteopenic postmenopausal women, genistein supported healthier bone-metabolism markers and bone density.

Supported by Trial 1

Menopausal support

Genistein is also studied for menopausal comfort more broadly, with separate research (beyond the bone trial cited here) examining effects on hot flashes and general well-being.

Supported by Trial 1

Estrogen-like support

As a phytoestrogen, genistein gently interacts with estrogen receptors, offering targeted support where natural estrogen has declined.

Supported by Trial 1

Mechanism of action

1

Selective estrogen-receptor activity

Genistein preferentially activates estrogen-receptor-beta, supporting bone and other tissues with a gentler profile than estrogen itself.

2

Bone-remodeling balance

Genistein supports the balance between bone formation and breakdown, favoring preservation of bone density.

Clinical trials
