Chrysin 500mg 30 capsules - 5,7-dihydroxyflavone from passionflower extract | discontinued
Jarrow Formulas Chrysin (5,7-Dihydroxyflavone) is a bioflavonoid found in passion flower (Passiflora coerula), that promotes healthy testosterone levels and lean muscle mass by inhibiting aromatase, the enzyme that converts testosterone to estrogen. This is called aromatization, which is an unwanted process for those who want to increase muscle mass.
In older men, a rise in levels of the enzyme aromatase increases the rate of conversion of circulating testosterone into estrogen, decreasing available levels of testosterone. Aromatase, found in a variety of bodily tissues, including brain, adipose tissue, placenta, blood vessels, skin, bone, and gonads, specifically facilitates the conversion of testosterone into estradiol and androstenedione into estrone, affecting male sexuality and reproduction, as well as muscle mass, hair growth, bone density, and sense of well-being. This hormonal decrease is further exacerbated by exposure to estrogen-mimicking compounds in food, water and pollutants. Research has shown that the bioflavonoid, Chrysin, or 5,7-Dihydroxyflavone, can help inhibit the production of the aromatase enzyme, and thus help maintain healthy levels of testosterone.
Natural Aromatase Arrest
Chrysin is a naturally occurring flavone, a type of flavonoid found in passionflower, chamomile, certain types of mushrooms and honeycomb, and especially rich in honey and propolis.
Flavonoids, which are polyphenolic compounds which lend pigment to plants and flowers, act as chemical messengers, physiological regulators, and cell cycle inhibitors in plants; in humans, they also have a wide range of biological and pharmacological activity. Numerous studies have shown Chrysin to inhibit the aromatization of androstenedione and testosterone into estrogens. Chyrin’s strong aromatase inhibition has been shown to act in microsomes, human pre-adipocyte cells, adrenocortical cells, and more. A study performed in 2008 suggested that Chrysin acts by increasing sensitivity of certain testicular cells to cyclic AMP (cAMP) stimulation of steroid hormone synthesis.
Animal studies have shown Chrysin to support sperm motility and concentration, and healthy blood testosterone levels. A study in which Chrysin was administered to 2-year-old male rats for a period of 30 days found significant support of overall sexual performance in those given Chrysin, compared with controls. Those given Chrysin (1 mg/kg) exhibited healthy libido, healthier sperm count, greater fertilization potential, and greater litter size when interacting with females. Research has also shown Chrysin to support normal cell replication, helping promote normal cell division and defending healthy cells.
Healthy Cell Replication and Normal Levels of Inflammation
In addition to its role as an aromatase inhibitor, Chrysin has also been shown to support cardiovascular health, promote cardiocyte health (heart cells) and inhibit foam cell formation. It is increasingly recognized for its powerful antioxidant properties, and its ability to promote normal levels of inflammation. In a 2015 study, Chrysin supported normal inflammatory response to environmental toxins, as well as normal cytokine release. Chrysin has also been found to significantly suppress the cyclooxygenase protein and messenger RNA expression in a dose-dependent manner, in vitro and supports a normal immune response to seasonal symptoms.
By supporting healthy levels of the aromatase enzyme, which has been shown to rise with increasing age. In men, Jarrow Formulas’ Chrysin promotes healthy testosterone levels and helps maintain levels of inflammation in a normal range, providing a range of benefits for overall health.
