Pre-Workout supplements are a great way to increase your energy levels before going to the gym. Most serious fitness enthusiasts will supplement with a good Pre-Workout powder before an intense weight training session. This allows the athlete to increase strength, training intensity and help with additional fat burning.

These supplements have some incredible benefits but they also come with a list of potential side effects. Although they are considered generally safe – many people have experienced adverse side effects.

Many of the top supplements like Jack3d, 1.M.R, GAT, Cellucor C-4 and N.O. Xplode have caused a few undesirable side effects. Although Pre-Workout side effects are typically pretty rare – it is important that you understand what side effects could potentially occur and what specific ingredients these originate from.

 

Pre-Workout Side Effects

 

Tingling Of The Skin

Almost every single one of the mainstream Pre-Workouts contain a supplement called Beta Alanine. Beta Alanine will help increase your energy levels and strength before a workout but it also can cause increased blood flow and a tingling of the skin on the surface.

This is that little tiny feeling of prickles on your skin about 20 minutes after you consume a Pre-Workout. If you are sensitive to Beta Alanine you will experience this side effect with Jack3d, 1.M.R, Muscle Pharm Assault and N.O. Xplode. Most of the Pre-Workout powders contain Beta Alanine, and tingling of the skin is probably the most common Pre-Workout side effect. This is not dangerous at all – and should actually make you feel good knowing that your Pre-Workout has kicked in and you can “feel” the energy.

 

The Crash

Another one of the most common Pre-Workout side effects is the crash. Most powders will not cause you to crash hard – but a few of the stimulant based ones may have this effect. It will depend on your genetics and what product you choose.

The reason why your body crashes is simple. If you consume a stimulant based product your body will be operating on a false energy source for a few hours and put through vigorous exercise. You are putting your body through intense physical trauma and bursting through it with maximum intensity. The end result is the evident crash.

Your body may crash when the stimulants leave your body and it can leave you feeling like a zombie for the rest of the day. This is really bad for those people who still have things to do after the gym or who train early in the morning. The crash usually isn’t this dramatic however – and it all depends on how many stimulants are in your Pre-Workout, genetics, and the intensity of your workout.

 

Stomach Cramping

A few people have complained of stomach cramping and intestinal issues from various Pre-Workouts. This side effect can be attributed to the high magnesium contents in some of the powders. Another thing to consider is that caffeine can act as a diuretic, and has the reputation to cause many people stomach issues. Spiking your nervous system is not the best thing for overall stomach health. Many of the top Pre-Workout powders have between 200-400 Mg of caffeine per serving.

Stimulants can also cause stomach problems. Pre-Workout powders are notorious for stimulants and a few people have reported stomach issues with stimulant based Pre-Workout powders.

The general population will not have stomach issues when taking a Pre-Workout, and it may just take your body a few times to adjust to the energy profile and ingredients. Try it out and take it slow and you will find a Pre-Workout powder that does not cause any stomach distress.

 

Pre-Workout Side Effects – Conclusion

It is best to assess your tolerance slowly. You should never exceed the recommended dosage and if one Pre-Workout powder gives you a negative side effect you should immediately figure out what ingredient is giving you problems and find another supplement that doesn’t contain it. There are some really good Pre-Workout powders available for everyone –so it’s all a matter of personal preference. Don’t forget to check out our Pre-Workout supplement reviews.
