i was wondering about green tea and that if it does indeed affect the 5a-reductase type I enzyme then surely there would be more testosterone that would be converted into dht with the type II enzyme? which isn’t being affected leading to maybe more hair loss depending on which type is more responsible for hair loss?
thanks for your time
I do not know of any studies that shows green tea affects 5a-reductase type I or type II enzymes. I have heard of many positive benefits of green tea, but even those claims are not well substantiated to my knowledge. It may sound dismissive or pessimistic, but herbal products are an unregulated field (since they are natural food products). I do enjoy green tea!
