Jarrow Chrysin 500

Jarrow Chrysin 500 is a supplement designed to boost testosterone through limiting the production of estrogen. Jarrow Chrysin 500 works by inhibiting the function of aromatase, the enzyme that converts testosterone into estrogen. By blocking this conversion, the body has more available testosterone that it can use to fuel anabolic muscle growth, raise metabolism, and improve overall body composition. Jarrow Chrysin 500 uses an ingredient which was at one time one of the most popular aromatase inhibitors on the market. But does this mean it is really effective?

Jarrow Chrysin 500′s Ingredients

Jarrow Chrysin 500 is named after the only ingredient it contains- Chrysin. Chrysin is an ingredient that was quite popular for aromatase inhibition back in the 80′s. Early in that decade, one clinical study showed that it was able to prevent aromatase from using up testosterone in order to create estrogen. Using this one study as justification, many supplements started using Chrysin, claiming that it would boost testosterone levels. Years later, more research has been conducted that shows this compound may not be as effective as previously supposed.

Credible tests conducted on Chrysin since the 80′s have shown that it is unable to manipulate levels of estrogen or testosterone in living subjects. The original study back in the 80′s was wrong because it wasn’t conducted among human subjects. In fact, it was not conducted on any living subjects. The aromatase inhibiting effects were only observed in a petri dish. All tests that have been done within living organism have shown that Chrysin cannot penetrate cell membranes in order to have an effect on the body thus rendering it completely useless.

Conclusion on Jarrow Chrysin 500

Based on an ingredient that most experts have deemed ineffective, we recommend not using Jarrow Chrysin 500. In fact, if you see Chrysin in any supplement on the market, steer clear. If supplements that contain Chrysin claim to be scientifically backed, don’t fall for their outdated studies. Chrysin will dilute and bring down any formula it touches.
