Good brand, seems to work as well as the other normal brand of NAC I usually purchase
For years, I have been taking a capsule of N-Acetyl-LCysteine (NAC) before I know will have a few drinks. For me, it seems to help lessen dehydration and hangover-like symptoms assuming you are not drinking a ton. If you drink too much, nothing will help. The Jarrow brand contains 500mg and my regular brand has 600mg but the Jarrow seems to work equally well assuming I'm only having a few drinks. I bought it since it was on a 70% off sale but has now gone back up to its normal price so I will probably go back to my normal brand unless it goes on sale again.When you first open a bottle of NAC, it may have a sulfur-like smell. I just leave the bottle open for a few days and shake it now and then and most of the odor goes away. The capsule size is very reasonable and they are tasteless assuming you swallow it whole and don't bite into it.
