Pre-workout supplements can give you the energy, focus, and performance you need to power through even the toughest workouts.

But can pre-workout actually go bad?

In this guide, you'll discover the shelf life of pre-workout powders and learn how to get the most out of each scoop!

What is Pre-Workout and Why Do We Use It?

Pre-workout supplements contain a blend of ingredients like caffeine, amino acids, and creatine to enhance your energy, endurance, strength, and focus during exercise.

Athletes use pre-workouts to help them push harder during their training sessions. The right pre-workout can provide an ergogenic edge and boost performance.

Top Ingredients in Pre-Workout Supplements

The key ingredients in pre-workout supplements work synergistically to prime our bodies for optimal performance.

Here are three of the most important ones to look for:

1. L-Citrulline

L-citrulline is an amino acid that can increase nitric oxide production, promoting vasodilation and muscle pumps. This helps guide oxygen and nutrients to muscles for enhanced endurance while working out.

2. Beta-Alanine

Beta-alanine helps buffer acidity in the muscles, fighting fatigue so we can grind out those extra reps. It can also help athletes stay focused.

3. Betaine Anhydrous

Betaine anhydrous, also known as trimethylglycine, is a naturally occurring compound that supports strength, power, and muscle protein synthesis. This can lead to gains in lean muscle mass and complement other ingredients.

How to Store Pre-Workout Supplements

At NutriFitt, we advise storing unopened pre-workouts in cool, dry areas, ideally at 70°F. Once opened, make sure your container is tightly sealed after use to preserve the quality and keep out moisture.

Refrigerating your pre-workout supplements after opening can prolong their shelf life. However, before using your pre-workout, allow it to come back to room temperature. This step enhances the effectiveness of ingredients for the best workout experience.

Signs Your Pre-Workout May Have Gone Bad

Watch out for these signs because they may indicate your pre-workout supplements may have expired or gone bad:

  • Clumping/caking instead of a fine, powdery texture suggests moisture exposure

  • A foul or stale smell instead of a pleasant or neutral odor

  • Fading or darkening of the color, which may signal degradation

  • Experiencing an upset stomach, nausea, or cramps after use

  • Having a reduced energy boost or other performance benefits

If you notice any of these signs, we recommend replacing your pre-workout with a new one. Don't let expired supplements stop your training momentum!

Pre-workout Shelf Life FAQ

Can I still use pre-workout after it clumps?

Avoid using clumpy pre-workout, as it indicates possible spoilage due to moisture exposure. It's hard to mix and may compromise your workouts. Instead, go for a fresh pre-workout for the best results.

How long does pre-workout last after you open it?

Pre-workout supplements typically last about 6-12 months after opening if they are stored in a cool, dry place and sealed tightly. Refrigeration can extend this period slightly. Be vigilant for changes in scent, texture, and effectiveness. When in doubt, it's better to replace it.

What happens if you take expired pre-workout?

Expired pre-workout may cause side effects like upset stomach, nausea, and cramping due to degraded ingredients. Avoid potential health issues and ineffective workouts by checking expiration dates and discarding old pre-workouts.
