Can You Drink Alcohol After Taking Pre Workout?

Quick answer

We found no official guidance written for pre-workout products, and ingredients vary by label. The CDC says caffeine does not reduce the effects of alcohol and may mask impairment, and the NIAAA says to ask a pharmacist or doctor about mixing alcohol with other products. If in doubt, do not combine them.

What the CDC says about caffeine and alcohol

The CDC states: “When caffeine is used with alcohol, it does not reduce the effects of alcohol on your body.” Caffeine may make you feel more alert, but your body processes the alcohol the same way. Feeling less affected may lead to drinking more.

The CDC also says energy drinks mixed with alcohol “may mask the signs of impairment and increase your risks of injury.” It lists higher blood pressure, irregular heartbeat and dehydration as other concerns. In November 2010 the FDA determined that adding caffeine to alcoholic drinks was not safe, and caffeinated alcoholic drinks may not be sold in the US.

What we could not confirm

We found no official source that tests pre-workout powders with alcohol. These products can hold caffeine, stimulants and other ingredients, and the amounts differ by brand. Read the label and the maker’s warnings.

Safer choices

  • Skip alcohol on days you take a stimulant pre-workout.
  • If you take any medicine or herbal product, ask a pharmacist or doctor first. The NIAAA warns that mixing alcohol and medicines puts you at risk for dangerous reactions.
  • Do not drive if you have been drinking, even if you feel alert.
