Pre-Workout Supplements: The Side Effects

Pre-Workout Supplements: The Side Effects


Everyone has seen infomercials about new 'magical' work out pills and supplements that can make you look like Mr. Olympia in days. Well if that were really true, then wouldn't we all be walking around with Arnold Schwarzenegger physiques with minimal effort?

The long term side effects of Pre-workout supplements are something of concern. Yes it is true that they increase muscle growth and can give you more energy. But it comes at a price that does not make it worth the while. This doesn't mean that all pre-workout supplements cause danger but you need to be vigilant about what you take.

What’s In Them?


The most widely used pre-workout supplement that is used is protein. Proteins are one of the main components in muscle building and at first glance one would think that isolated proteins such as Whey are a healthy intake of adding muscle.

Taken correctly and in small doses that fact does hold true but if too much protein isolate is ingested it can be harmful for the kidneys in the long run. A healthier alternative to protein powders are the nutrient and protein rich eggs. Adding them to your pre-workout supplement milkshake will give you great results without the harmful side effects.


Many long term affects of pre-workout supplements are because of the over use of substances. Most of these supplements are based on caffeine, with each serving containing at least 100 – 300 mg, where as a cup of 8 oz coffee only contains about 100 mg.

Now when caffeine enters our body, our internal systems start working in over drive to evacuate the substance and cleanse the body. This means there is increased heart rate, blood pressure, the kidneys having to work harder and mental mistake. Excessive caffeine can cause hypertension and put undue stress on adrenal glands which leads to adrenal fatigue.

Dimethylamylamine Or (DMAA)

The danger of pre-workout supplements can clearly be high-lighted with the use of DMAA. DMMA is a simple aliphatic amine and has been marketed under many names as a dietary supplement. The substance raises the stress on your heart and blood pressure.

Side Effects Of DMAA

  • Seizures
  • Cardiac Arrest
  • Fainting
  • Liver failure
  • Heart palpitations
  • Kidney Failure


Creatine is a natural substance produced in the body to create energy or ATP. It's added into many stacked pre-workout supplements or is even available individually. Creatine like all other pre work out supplements delivers a boost of energy.

The long term side effect of this pre workout supplement are that it can cause are muscle and stomach cramps, diarrhea, nausea, kidney stress and dehydration.

The top health experts around the world advise people that you should never take a supplement without the prior recommendation of a health care professional. Most supplements are hazardous to your health for the reason that they do not have to be tested.

"Stacked" Pre-workout supplements dangers exist because they are a mixture of different substances that all have an adverse side affect.

Also if the bad affects of pre workout supplements did not exist. Why, would your doctor, not give you weight loss pill instead of telling you to start exercising on a regular basis? The simple answer is not only do they not work as well as they claim but the side affect’s can have serious negative impact on your physical and mental health.

So remember that it is absolutely essential that you have your doctor’s recommendation before taking any supplements.
