  • For Consumers of Alcohol
  • With Vitamin C and B
  • Dietary Supplement

Take RU-21 by Spirit Sciences USA before your first drink.

Warnings: RU-21 does not prevent alcohol inebriation. RU-21 is not a license to binge drink, and should not be counted upon to prevent health consequences of excessive alcohol consumption and/or improve the ability to operate a vehicle while intoxicated.

Notes: Do not chew or crush.

Recommended Use: RU-21 is formulated to support the body's ability to metabolize alcohol, which means interfering in a metabolic process. Therefore, for best results it is important that you take RU-21 at the time of alcohol consumption.

Take two pills before your first alcoholic drink, and two pills after your last drink. However, because individual metabolisms vary, modifications of these directions are acceptable. In studies, 1 tablet per 2 drinks was shown sufficient for most males and 1 per drink for most females.

RU-21 got rid of the headaches in the morning, but not the upset stomach feeling. Also makes your urine very, very yellow. Like neon yellow, almost kind of green. But I would recommend taking this, made a difference.

Used as directed has some efficacy in reducing the effects of alcohol and alleviating hangovers.
