are you younger than 35? because if so no shit nac doesn't do anything for you. nacs only benefit is the promotion of glutathione, limiting factors glycine and cysteine(<-nac). glycine absorption depletes naturally as we age, cysteine absorption depletes naturally as we age. cysteine is additionally only found in small dosages in food supplies compounding the issue. as a young man or even boy, you would have zero issues absorbing cysteine. so nac would do nothing for you.
