4 Alarming Side Effects of Pre-Workout Supplements

It is in our nature to take the easy way out when it comes to exercise. Many turn to pre-workout supplements only to experience short-lived results coupled with alarming side effects. In this article, we’ll detail what pre-workout supplements are, what pre-workout side effects we should be aware of, and how to avoid them best.

What Are Pre-Workout Supplements?

Pre-workout supplements, or “pre-workouts,” are powders with many unknown ingredients that you mix with water to consume. You may ask, what does pre-workout do exactly? In theory, it will give you more energy while working out so you can gain more muscle and lose more fat. Yet, like using drugs, the high might be intense the first few times. In these moments, you may experience a boost. But, soon enough, many find themselves chasing an elusive high while suffering the consequences.

Is Pre Workout Bad For You?

Although pre-workout supplements can have positive effects and are relatively safe, that does not mean they are risk-free. They can also produce many alarming pre-workout side effects. Before consumption, it’s important to investigate what potential pre-workout side effects you may encounter.

1 Diarrhea

Diarrhea is a common pre-workout side effect because many ingredients are unknown. As a result, if you have a sensitive stomach, you may have to use the bathroom immediately after consumption. If you experience this, try adding more water to the mixture.

2 Headaches Due to Dehydration

Both pre-workout supplements and other caffeinated drinks lead to increased dehydration because they act as diuretics. Diuretics cause you to urinate more often. The combination of sweating during exercise plus pre-workouts leads to your body losing a lot of water. The most common result is severe headaches. Suppose you are experiencing headaches while consuming pre-workout supplements. In that case, it is either best to consume more water throughout your workout or to stop drinking them altogether.

NOTE: If your headaches are popping up post workout, you could be suffering from exercise headaches.

3 Increased Blood Pressure

Pre-workout supplements and other stimulants like caffeine will increase blood pressure. If you have high blood pressure already, it may be best to avoid pre-workout supplements altogether. If you have normal blood pressure, it is still best to take caution when doing high-intensity workouts.

4 Insomnia

Insomnia is the worst of pre-workout side effects and can have the most detrimental consequences. Why? Because pre-workout supplements are loaded with caffeine. Caffeine has a half-life of 6 hours, meaning after 6 hours, half the amount of caffeine you drink is still circulating in your system. For pre-workout supplements, this can be a lot and can severely affect your sleep. 

How To Avoid Pre Workout Side Effects

One option to avoid pre-workout side effects is getting more sleep to feel more rested before your next workout. A second option is trying milder forms of caffeine like coffee or tea. However, those forms may still cause results similar to pre-workout side effects.

Another option is to consider Regen Labs FlexMax™. The key reason whyFlexMax™ stands out as a better option is because it is nitric acid-free. This is crucial if you want to avoid pre-workout headaches. Also,FlexMax™ uses all-natural ingredients aimed at optimizing growth, stamina, and recovery. The most potent ingredients in its innovative formula are BPC-157 and Epicatechin.


BPC-157 is a synthetic peptide with fifteen amino acids derived from a digestive fluid. It shows high effectiveness in restoring and rebuilding tissue. It also produces an angiogenic effect which creates new blood vessels and speeds up blood flow to injured or ailing areas of the body. By catalyzing the body’s natural ability to heal and turbocharging your workout, BPC-157 is an excellent alternative to pre-workout supplements.


Epicatechin is flavanol commonly used for treating sarcopenia, which is the body’s tendency to shed muscle as we age or reduce activity. Epicatechin has proven to reduce myostatin (a marker that reduces muscle growth), allowing for maximal muscle growth. By inhibiting myostatin, a protein that limits the amount of muscle mass you can gain, epicatechin can improve muscle growth and the maintenance of healthy muscle tissue. Epicatechin can help you reach peak performance without having to suffer any pre-workout side effects.

We’ll never stop looking for an easy way to get the most out of our workouts. Yet, in almost all cases, the simple option is almost always better. Regen Labs FlexMax™ keeps it simple, which allows you to focus on reaching peak performance. Give it a try and say goodbye to pre-workout side effects!
