Soy Isoflavones

30 vegetarian capsules

Item Catalog Number: 01649

NON GMO Product

After menopause, maintaining a healthy heart, bones and metabolism is especially important for women—and soy can help. The benefits of soy have been shown for decades in published studies.1

In particular, soy isoflavones like genistein, daidzein and glycitein have demonstrated a wide variety of beneficial effects in postmenopausal women, including supporting cardiovascular, cerebrovascular, metabolic and bone health, as well as healthy cell division.1-4

Benefits at a Glance:

  • Ideal daily supplement for women post-menopause
  • Supports heart, bone & cellular health
  • Can help maintain already-healthy blood pressure
  • Provides soy isoflavones such as genistein, daidzein and glycitein

Soy Isoflavones

Soy is rich in phytoestrogenic plant-derived compounds with estrogen-like effects called isoflavones, such as genistein and daidzein. These isoflavones activate estrogen receptors, but they prefer the receptor Erβ—which is found mainly in bone, urogenital tissue and the cardiovascular system—over Erα, which is found mainly in breast and uterine tissues.5

As a result, soy isoflavones have demonstrated benefits for women after menopause, such as helping maintain bone density as well as healthy blood lipid levels and glucose metabolism and promoting heart health.6-9

Soy isoflavones also support healthy cell signaling and help protect against oxidative stress.4,13
