grapefruit juice inhibits CYP3A, a class of enzymes, also the biggest class in the liver. CYPA4 is responsible for metabolizing dutasteride, finasteride, testosterone, and estrogen. (see list of substrates)
Some people on here are drinking grapefruit juice to keep dutasteride levels higher. While this sounds good (inhibit DHT), you need to make sure you are not also inhibiting the breakdown of DHT in the blood. Otherwise it won't go away. Also, other hormones as well. I think a little grapefruit is fine. But I'd not take it every day.
still trying to find out which enzyme metabolizes DHT. Probably this same one.
