Does Pre-Workout Expire?

Like any supplement, pre-workouts will typically have a use by date printed on the tub. Pre-workout supplements tend to go bad if they are made with certain ingredients like fatty acids or fish oil, or ingredients that absorb moisture. If your pre-workout has gone bad, you shouldn't take it anymore because it's unlikely to be effective and can make you sick. If your pre-workout is beyond the date, yes it has expired. Most ingredients will work best within the date but some people will use the supplement anyway.

There are times that you shouldn't use a past date supplement; for example, if you have moldy pre workout. This should be immediately disposed of; there may be some side effects when you consume expired pre-workout like gas or an upset stomach. 

How Can You Tell If Your Pre-Workout Has Gone Bad?

• Smell: Be aware of the normal smell of your supplements when you first open the tubs. If the tub starts to have a foul or stale smell, it could be a sign that it has been open for too long or gone bad. 
• Clumpy: Once the vacuum seal is broken, moisture is likely to get into the tub and will start making the powder clumpy. There are ways to avoid this, read this blog post to find out how to keep your pre-workout from getting clumpy.
• Doesn't Mix: When your pre-workout doesn't mix easily, that's another way to tell if your pre-workout has gone bad. After shaking your pre-workout, if the powder remains unmixed with a chalky texture, it could be an indication that your pre-workout has gone bad.
• Mold: Mold is a pretty obvious sign that something is bad and happens when your products aren't stored correctly. Get rid of moldy powder immediately because you can get food poisoning.
