NO is also, HOWEVER, a mediator of inflammation in the liver. This is okay to enhance NO production, when the liver is healthy; they should be strictly limited in cases of an inflammatory response in the liver (hepatitis), which can occur from poor diet (eg high 'bad' fats), too much alcohol, in fact liver function tests are recommended regularly for bbs, esp during hypertrophy, double esp. if anabolics are used.
...Good explanation, NO after all is a free radical.
