How Long Does Pre Workout Stay Good After Mixed?
Commonly, your supplement will remain good within 12 hours after being mixed. However, pre-workout loses potency if you combine it with other ingredients. For this reason, we recommend consuming it within 12 hours of mixing.
This is because drinking an expired pre-workout causes you to feel nauseous. If you have a sensitive stomach, it’s best to play it safe and consume it within the set time.
However, depending on the type you are intaking, some last up to 24 hours after being mixed. If unsure, it’s best to check the label or contact the manufacturer.
What are the Factors that Affect How Long Pre Workout Lasts?
Here are a few factors that affect how long your pre-workout drink lasts:
1. Type of Pre Workout
As mentioned earlier, the type of pre-workout you’re taking affects how long it lasts. Taking a pre-workout with caffeine will likely have a shorter shelf life than one without caffeine because it will break down over time.
Although many pre-workout supplements have similar ingredients, they have different expiration dates. For this reason, its shelf life could vary, including the type of supplement you’re taking.
Another factor affecting your pre-workout shelf life is how you store it. If you hold it in a cool, dry place, it will last longer than if you keep it in a warm or humid environment.
Therefore, we recommend storing it in a cool, dry place like your pantry or cupboard. You should seal the container tightly so that moisture and air don’t get in.
As we mentioned earlier, mixing your pre-workout with other ingredients affects its shelf life. If you combine it with other pre-workout supplements, it will likely lose potency over time.
The ingredients start to break down when mixed with other substances. For this reason, we recommend consuming it within 12 hours of mixing.
4. Active Ingredients
Different active ingredients in your supplement can have different potencies. For example, caffeine is a stimulant and will start to break down over time.
Creatine is another ingredient that affects the shelf life of your supplement since it’s a protein that starts to break down when exposed to air.
5. Expiration Date
Of course, the expiration date of your pre-workout can affect how long it lasts. Once it expires, the active ingredients will likely break down and lose their potency.
For this reason, we recommend consuming it before the expiration date. You can check the label or contact the manufacturer if you’re unsure of the expiration date.
How Long Can You Store Your Pre-workout Supplements?
Generally, you can store it for up to two years. However, this doesn’t mean it will still be as effective after two years.
The shelf life of your pre-workout can be affected by several factors, including the type of supplement, how you store it, and the expiration date.
It’s important to note that the shelf life of your products can vary depending on the manufacturer. For this reason, it’s always best to check the label upon opening to track how long it will last.
Regarding storage, we recommend keeping it in a cool, dry place like your pantry or cupboard. You should also tightly seal the container so that moisture and air don’t get in.
What are the Typical Ingredients in Pre-workouts?
Caffeine is a stimulant that improves focus and increases energy levels. Most pre-workout effects contain caffeine to keep you alert and improve your cognitive function during your training session, which aids in an energy boost.
It’s important to note that too much caffeine intake can cause side effects like jitters, anxiety, and heart palpitations.
Protein is a macronutrient that’s essential for muscle growth. Protein is the building block of muscle tissue and is necessary for repairing and rebuilding muscle mass after exercise.
Most pre-workout supplements contain whey protein powder, a type of protein easily absorbed by the body.
Creatine is a compound that’s found naturally in muscle tissue. Creatine monohydrate improves performance by increasing the production of ATP, which is the body’s primary energy source.
ATP is responsible for providing the energy needed for muscle contraction. By increasing ATP production, creatine can help you to exercise for longer and with more intensity.
Beta-alanine is one of the most common amino acids that improve exercise performance. You can find this ingredient in pre-workouts designed to enhance performance. Beta-alanine delays fatigue during exercise and improve your overall performance.
This type of amino acid can improve blood vessels’ flow and increase nitric oxide levels. It’s often found in pre-workouts designed to improve blood flow and increase nitric oxide levels. L-citrulline offers increased blood flow and increased nitric oxide levels.
These are common ingredients that you can find even on popular pre-workouts in the market. You can also find rarer ingredients in some pre-workouts.
How Far in Advance Can You Mix Pre-workout?
When it comes to your fitness journey, time management is vital. That’s why we always recommend mixing your pre-workout product in advance. This way, you can save time and ensure you take your pre-workout at the optimal time.
Most pre-workouts instructions recommend mixing it 20-30 minutes before your workout. As a result, this gives your body enough time to absorb the nutrients and prepare for training.
If you’re short on time, you can mix your supplement 10 minutes before your workout. However, this may not be enough time for your body to absorb all the nutrients.
It’s important to note that many pre-workout supplements may not be as effective if you mix them too far in advance. Since pre-workout products are made up of different ingredients, they can start to break down over time.
Therefore, we recommend combining your pre-workout no more than 30 minutes before your workout.
Can You Keep the Pre-workout in the Fridge Overnight?
If you plan on preparing your pre-workout at night, storing it in your refrigerator will keep it fresh. This is because the cool temperature will preserve the nutrients in your supplement.
Plus, storing your pre-workout product in the fridge overnight would reduce the risk of bacterial growth and prevent such problems as moisture and mold. But if you’re short on time, you can also keep it at room temperature.
However, you should make sure to mix your supplement right before you consume it. This is because the nutrients can break down over time.
When ready to use it, take it out of the fridge and mix it with cold water. Mixing it with hot water can cause the nutrients to break down and make the pre-workout less effective.
Signs your pre-workout is still good.
When it comes to pre-workouts, it’s essential to know when it’s time to replace them. Here are a few signs that your pre-workout is still good:
- The color and smell of the supplement are the same as when you first opened it.
- There is no change in texture or consistency.
- The supplement is still within its expiry date.
If you notice changes in your pre-workout supplement’s color, smell, or texture, it’s time to replace it. These changes can indicate a build-up of bacteria or that the nutrients have started to break down.
When in doubt, avoiding caution and replacing your supplement is always best. This will ensure you get the most out of your workout and not risk your health.
How to Identify if Your Pre-Workout Has Gone Wrong?
Like other food or beverage items, sometimes it’s hard to spot whether your supplement has gone wrong. However, there are a few signs that you can look out for:
Color has changed
For most pre-workouts, the color is usually consistent. If you notice that the color has changed, it could signify that it has gone wrong.
Although it’s not as noticeable, if you’ve taken pre-workout supplements for a while, you might notice that the color has changed over time.
Pre-workout has chunks or clumps
If you notice that your supplement has chunks or clumps, it’s a sign that it’s gone wrong. This is because the nutrients can break down over time.
You can also see and feel that your supplement has a different texture. If it’s no longer smooth, it’s a sign that it has gone wrong.
Smell has changed
Like other beverages and food products rotting, its distinct smell is the number one factor to identify if it’s gone wrong. If your supplement has a different smell, it’s a sign that it’s no longer suitable to consume.
It’s better to be safe than sorry. Even a tiny change in smell can signify that it’s time to get a new supplement.
Taste has changed
If the taste of your supplement has changed, it’s a sign that it’s gone wrong. There might be molds or bacteria in it, which can cause it to taste different.
If you notice any of these signs, it’s best to throw out your supplement and get a new one. Although it might be tempting to try and salvage it, it’s not worth the risk.
It will no longer be as effective
Of course, once your supplement has gone wrong, it will no longer be as effective. This is because the nutrients can break down over time.
If you consume a supplement that has gone bad, you might not get the same results as you would if it was fresh.
You might also experience negative effects, such as an upset stomach or diarrhea, because of the bacteria growing in your pre-workout supplement.
So, if you notice any of these signs, it’s best to throw out your supplement and get a new one. Although it might be tempting to try and salvage it, it’s not worth the risk.
