Jarrow Chrysin 500

Chrysin is a flavonoid derived from the blue passion flower (Passiflora caerulea) that supports healthy testosterone levels in men. Chrysin works by inhibiting the action of the enzyme aromatase, which is responsible for the undesirable process of converting testosterone to estrogen. Healthy testosterone levels in men is key to lean muscle mass formation, stamina, and healthy libido.

  • Chrysin promotes healthy levels of the male hormone testosterone. Testosterone is the primary hormone responsible for the primary male sex characteristics. It is responsible for the formation of lean muscles, adequate energy production, healthy libido, and normal sperm production. Chrysin helps in maintaining adequate testosterone circulating in the blood to maintain these unique male functions. Low levels of testosterone can lead to weakness, loss of libido, and more fat deposits.
  • Chrysin supplements are known to reduce the side effects of anabolic steroids usually taken by athletes and bodybuilders. Anabolic steroids can cause several negative side effects for men like the growing of breasts.
  • As a natural aromatase inhibitor, Chrysin can help diminish the negative side effects of unbalanced estrogen. Some forms of cancer affected the breast, uterus, and ovaries depend on the body’s unbalanced estrogen to fuel the growth of cancer cells.
  • There are clinical studies suggesting that Chrysin possesses powerful anti-viral activities. It ranked the highest among the 34 natural and synthetic flavonoids in terms of therapeutic index. Chrysin is found to exhibit powerful defenses against coronavirus.

Chrysin is classified as a flavone, a specific kind of flavonoid naturally found in propolis, honey, and some plants like Passiflora caerulea or the blue passion flower. There are very strong evidences on Chrysin’s abilities to generate beneficial effects on keeping the body healthy. It is classified as a natural aromatase inhibitor, a kind of compound that supports healthy testosterone levels. Chrysin appears to work by preventing the conversion of testosterone to estrogen by blocking the action of aromatase. Aromatase is the hormone that stimulates the testosterone to estrogen conversion, a process called aromatisation. Testosterone is the hormone responsible for producing the unique physical and emotional characteristics of men from women – like more muscular physique, deeper voice, stronger stamina, body and facial hair, and more active libido. Estrogen works the same for women to maintain their breast, ovaries, uterus, and other distinct female characteristics. However, each sex also produces the hormone of the other in very small amounts. The enzyme aromatase is present in both male and female, and increased aromatase activities can limit testosterone levels in men. It is when increased aromatisation that trouble begins, where more estrogen are produced in the male’s body than testosterone. Reduced testosterone leads to low energy and fatigue, loss of libido, excessive fat deposits, and increased estrogen can even lead to the development of breasts in men.
