Pre-workout supplements are popular with gym-goers because they can provide a boost of energy to potentially help improve your athletic performance. Like any supplement or product, though, they may have expiration dates and can lose potency if stored incorrectly or kept for too long.

What Is Pre-Workout?
A pre-workout is a supplement typically made up of a mix of amino acids, caffeine, and vitamins that you can take before training for a motivational boost. Pre-workouts can come in powder, drink, capsule, and gummy form.


Pre-workout supplements are popular among bodybuilders and fitness enthusiasts who take them to help amplify their energy levels, enhance their focus, and increase their blood flow potentially leading to improvements in overall strength performance. (1) If you’ve been training hard but stalling on progress, pre-workout may even help you break through a training plateau.


Common Ingredients
Pre-workout supplements vary, and different brands create blends of different ingredients. The most common ingredients in multi-ingredient pre-workout supplements (MIPS) were found to be caffeine, creatine, beta-alanine, citrulline, taurine, and tyrosine. (2) Pre-workout supplements also often contain BCAAs, arginine, B vitamins, and other stimulants.


Each of these substances serves a different purported function, and when they are blended together, they may offer exercise-enhancing benefits.

Below are some common pre-workout ingredients and how they might boost your training:


  • Caffeine and other stimulants can help give you an energy boost, increase your focus, and may delay fatigue. (3)
  • Citrulline and arginine are nitric oxide boosters that help increase your blood flow which then deliver oxygen and nutrients to your muscles while you train. (4)
  • Creatine helps increase your ATP to replenish your energy quicker during high-intensity training like weightlifting, and helps you have better muscular contractions. It may also play a role in muscle protein synthesis, helping you to build muscle when combined with enough food and training. (5)
  • Beta-alanine is an amino acid that may help decrease lactic acid build-up in your muscles which can delay fatigue. (6)
  • BCAAs (or branched-chain amino acids) are essential amino acids needed for muscle protein synthesis to happen in your body when paired with resistance training and adequate calorie and protein intake. They also may aid in muscle recovery. You can also get BCAAs by consuming complete protein sources, including food and protein powder. (7)
  • Taurine is an amino acid that can function as an antioxidant which may reduce oxidative stress and potentially increase your endurance. (3)
  • Tyrosine releases adrenaline and dopamine, which may help increase focus during high-stress moments—weightlifting potentially included, but more research is needed. (8)

Does Pre-Workout Go Bad?
Yes, pre-workout can go bad. Like any ingestible product, pre-workout supplements have a shelf life, and they may lose quality and effectiveness over time.


The U.S. Food and Drug Administration (FDA) does not require supplement companies to list an expiration date, so not all pre-workout supplements will include one. (9) If there is an expiration date, it’s helpful to pay attention to the wording.

If there is a “use by” date, it may indicate that the product can become biologically spoiled and pose a health threat if ingested after the date. If there’s a “best by” date, it indicates that the quality may be diminished, but it’s not unsafe to consume. (10)


To minimize confusion, the FDA is encouraging the food industry to use the language “best if used by” on packaged products to indicate that the date is related to quality, not safety. This language suggests that you don’t need to discard your product if it’s past the date as long as it is stored correctly. (11)



How to Tell if Your Pre-Workout is Bad?
Pre-workout supplements typically last six months to two years, depending on the brand. They can be pricey, so you probably want to be sure it’s bad before getting rid of it. Here are a few signs to look for when deciding whether or not to take a scoop.


Check the Expiration Date
If there’s an expiration date on your pre-workout, check that out first. Even if you’re past the date, if it was “best if used by,” it might not necessarily be bad, especially if you’ve stored it properly or it’s unopened. But if it’s a pretty old pre-workout and has already been opened, it might not be good anymore.


Check for Mold
A major sign of bad is moldy pre-workout. If you see any mold, chuck it.


Check for Clumps
Is your pre-workout clumpy? If so, it’s not necessarily bad, and you may be able to smooth them out. But pre-workout should generally be a fine powder, so clumps can be a potentially bad sign.


Check for Smell and Color Change
If you notice a bad smell when you open your tub, it may be done. Take a look at the powder as well and notice if the color has changed at all. Both can be signs of a good pre-workout gone bad.


Pay Attention to Potency
This one is tough because it’s pretty subjective, and there are many reasons that pre-workout may affect you differently. Pre-workout may lose its potency over time, so if you start to notice it’s not working as well as it used to, that’s a potential sign.



How to Keep Your Pre-Workout From Going Bad
There are a few steps you can take to keep your pre-workout from going bad too quickly. Optimal storage is key to keep out moisture and sun, which can lead to the dreaded mold. Here are a few tips to help your pre-workout last longer.


Store in a Cool Dry Place
Keep your pre-workout in a cool and dry place. Humidity can lead to moisture, which leads to clumps, mold, and a general decrease in quality. Choosing a cool, dry cabinet away from your bathroom, sink, and stove may help.


Keep Out of Direct Sunlight
Direct sunlight on your pre-workout can expose it to heat and humidity. Keeping it in a closed cabinet away from a window can prevent degradation due to too much sun.


Close Tightly
Close your pre-workout tub as tightly as you can. If it’s in a tub, screw on the top well. If it came in a package with a vacuum seal, try your best to seal it up in between uses to keep out moisture.


Keep the Silica Packet
Your pre-workout may come with a silica packet—don’t get rid of it. It helps absorb moisture and prevents clumping and mold.



Can You Drink Expired Pre-Workout?
You can drink expired pre-workout, especially if it doesn’t have any other signs of going bad: mold, clumps, bad smell, or changed color. However, if it’s expired and has one or more of these signs? It’s probably best to get rid of it.

Drinking expired pre-workout may intensify some of the side effects — particularly an upset stomach. It may also lose its potency and effectiveness, so you may notice you’re not getting the energy boost you used to back when you first bought it.


Wrapping Up
There are plenty of pre-workout supplements to choose from to help you feel energized and focused to crush your workouts. Maybe you go through a phase where you’re not using it for a while, and then you go to grab your tub and notice it’s past its expiration date. If you take it anyway and later get an upset stomach, it may have been bad.


Next time, open it up and inspect the quality. Look for clumps, mold, bad smells, or changing colors. If it passes all those tests—you should be good to go. To help it last longer and prevent any spoiling, store your pre-workout in a cool, dry place away from direct sunlight. Seal it up tight to keep moisture out. Shake it up and hit the gym.
