EstroQuench 120ct


EstroQuench is a Hormone Specific Formulation of ingredients that support the normal function of the bodies endogenous aromatase inhibitors.


EstroQuench by Douglas Laboratories is a Hormone Specific Formulation of ingredients that support the normal function of the bodies endogenous aromatase inhibitors.

This formulation is designed to quench excessive production of estrogens while supporting optimal function of androgens by maintaining the health of androgen-producing glands.

Hormone Specific Formulation, provided by Douglas Laboratories and formulated by Dr. Joseph J. Collins, was created to support the optimal function of specific hormones through the use of hormone-specific adaptogens and functional modulators of hormone actions.

This formulation may be used as part of a hormone health program with dietary and nutrient support. It may also be used by clinicians as an adjuvant to support optimal hormone health in patients who have been prescribed bioidentical hormone therapies.


  • Supports healthy estrogen production and function.

Functions and Mechanism of Action

Aromatase (a cytochrome P450 enzyme {CYP19}) is the enzyme that controls the conversion of androgens to estrogens. More specifically, aromatase is the enzyme responsible for catalyzing the biosynthesis of androstenedione into estrone, and the biosynthesis of testosterone to estradiol.

Estrogens include the broad range of aromatized hormones created form androgens. The specific attribute of estrogens that separate them from progestogens, androgens and corticoids is that estrogens are the only aromatized steroid hormones.

Estradiol, the most potent endogenous estrogen, is biosynthesized by aromatization from androgens by aromatase. Both males and females produce endogenous estrogen from testosterone via the enzyme aromatase.

In aromatase inhibition, there is less conversion of testosterone and other androgens into estrogens. The result is lower estrogen levels and higher androgen levels. Flavonoids have the potential to modulate aromatase, as indicated by preclinical studies, and support the normal function of endogenous aromatase inhibitors.

The primary functions of EstroQuench is to support healthy Estrogen metabolism; maintain adequate levels of the androgen metabolites, which regulate aromatase; and support the function of testosterone-producing glands.

Bioperine is a patented extract of piperine (black pepper fruit) that has been clinically tested in the United States and found to significantly enhance the bioavailability of various supplement nutrients and herbal extractsby moderating P-glycoprotein (P-gp) and CYP34A.
