86 results about "Equol" patented technology

Equol (4',7-isoflavandiol) is an isoflavandiol estrogen metabolized from daidzein, a type of isoflavone found in soybeans and other plant sources, by bacterial flora in the intestines. While endogenous estrogenic hormones such as estradiol are steroids, equol is a nonsteroidal estrogen. However, only about 30-50% of people have intestinal bacteria that make equol. Equol can exist in two enantiomeric forms, (S)-equol and (R)-equol. (S)-Equol preferentially binds estrogen receptor beta.

Use of equol for treating skin diseases

Equol (7-hydroxy-3(4′hydroxyphenyl)-chroman), the major metabolite of the phytoestrogen daidzein, specifically binds and blocks the hormonal action of 5α-dihydrotestosterone (DHT) in vitro and in vivo. Equol can bind circulating free DHT and sequester it from the androgen receptor, thus altering growth and physiological hormone responses that are regulated by androgens. These data suggest a novel model to explain equol's biological properties. The significance of equol's ability to specifically bind and sequester DHT from the androgen receptor have important ramifications in health and disease and may indicate a broad and important usage for equol in the treatment and prevention of androgen-mediated pathologies of skin and hair. Thus, equol can specifically bind DHT and prevent DHT's biological actions in physiological and pathophysiological processes affecting skin and hair.

Composition and products for enabling the production of equol in vivo

The isoflavone equol has the ability to mimic estrogen at the receptor level, as well as the ability to mitigate the deleterious effects of dihydrotestosterone (DHT) in vivo, thus resulting in potential health benefits for both men and women. Only an approximated one-third of the global population has the inherent ability to produce equol. Diet and colonic bacterial composition play a large role in natural equol production. The present invention can increase the probability of producing significant quantities of equol in vivo. Experimentation has shown the repeatable and measurable evidence of equol. Data from male test subjects indicates clinically significant positive effects on androgenic alopecia and acne vulgaris.
