Your gym clothes are on, your sneakers are laced, and you’re ready to hit the weights: all that’s left is to take your pre-workout. But if you dread that itchy, tingly feeling that often happens after taking pre-workout, you’re not alone: many people experience this uncomfortable side effect when using pre-workout powders or supplements. Fortunately, there are techniques you can use to nix that itchy feeling and focus on your workout. Keep reading to learn exactly why pre-workout makes you itch and what you can do to get rid of it and focus on your exercise routine.

Things You Should Know

  • Pre-workout makes some people itch because of beta-alanine. This amino acid can cause a side effect that causes tingling and itching.
  • Stop the pre-workout itch by splitting up your pre-workout into multiple doses.
  • Alternatively, try a sustained-release pre-workout or a pre-workout made without beta-alanine to avoid any uncomfortable side effects.

  1. Beta-alanine is the beta amino-acid inside of pre-workout that delays muscle fatigue and loss of power. However, beta-alanine can also cause an effect called paresthesia, which isn’t harmful, but does cause tingling and itching. [1] Researchers aren’t 100% certain why beta-alanine does this inside the body, but it’s common enough that more studies are being done on it.

How to Stop Itching

  1. Many people find that instead of taking an entire dose at once, breaking up their pre-workout into 2 or 3 doses helps prevent the itching. Try taking smaller amounts of pre-workout throughout the day to stop that tingly feeling. [2]
    • Pre-workout typically lasts in your system for about 4 hours. Try starting your first dose about 4 hours before you plan to work out.
  2. Since beta-alanine is the ingredient that causes the itching, researchers have found that a sustained-release formula helps circumvent uncomfortable side effects. [3] Look for a pre-workout that says “sustained-release” on the packaging to try out this new version.
  3. Beta-alanine is the ingredient that causes the pre-workout itch. While beta-alanine is a common ingredient in pre-workouts, you can find pre-workout brands without beta-alanine. These formulas may be better for you if you’re particularly sensitive to the side effects of beta-alanine.

    Expert Answer
    It definitely can, especially if you aren't healthy enough when you start using it. It's really important to make sure you get your health on point before you start exercising and using pre-workout formulas—if you're not healthy enough, pre-workout formulas can actually harm you.

      Warnings

      • Some people use creatine for their pre-workout, while others use a caffeine-based supplement to get their heart rate up and warm up their muscles before exercising. Although these options add in a little more intensity, do not use them unless your health is in check. If you're not healthy enough, those things can actually harm you. Consult a doctor before using a pre-workout or starting an exercise regimen.
