Product Information


Contains No Hormones or Estrogen
Herbal Hormonal Balance
  • Supports pre- and post-menopausal hormonal balance
  • Modulates 5-lipoxygenase; helps support normal bone growth

A Supercritical New Chapter in Hormonal Vitality
New Chapter's
formulation features Black Cohosh, which major clinical trials show to be an important hormone balancing tonic. Our full-spectrum Black Cohosh extract is Potency Assured™ to contain triterpene glycosides. The formulation also includes supercritical extracts of Rosemary and Ginger, which contain many of nature's most studied and respected anti-aging constituents that inactivate free radicals. As reflected in the USDA Phytochemical Database, constituents in our Rosemary and Ginger extracts, similar to the hormone estrogen, modulate an enzyme called 5-lipoxygenase (5-LO). Recent scientific research suggests that estrogen may promote bone growth by modulating 5-LO, so our extracts may play an important role in supplementing natural estrogen's bone maintenance capability.

New Chapter's Supercritical Herbal Extracts
"Supercritical" means Super Purity, Super Potency, Broad Spectrum, and No Chemical Solvents. We take nature's finest herbs and then extract and highly concentrate (as high as 250 to 1) their precious, full spectrum ingredients. We do not isolate single ingredients or spike our extracts with synthesized additives. We deliver the wisdom of nature with the complexity and organic nuances of the natural herb preserved for you. In fact, the supercritical process is the gentlest way to extract these delicate plant compounds in a manner to optimally preserve their potency and stability. And when you take New Chapter's supercritical extracts, neither you, nor the environment, have to contend with chemcial solvents.
