Been taking this with grape juice and thiamine(B1) the nights I go drinking and the combo is working. Last time I drank over 10 servings(I drink this much maybe 5 times a year so I don't have real tolerance) combo and went straight back to school after 7 hours of sleep as usual. The capsule is about the size of largest soft gel -capsules I've seen.

I read that this amino acid was good for hair and nails so I thought I'd try it. Well, it seems to be working. My hair and nails appear to be growing faster. Other than that I haven't noticed anything else. I take one in the morning and one at night, so far. I have used many NOW products and I am very satisfied. iHerb prices are the best!!!
