Everyone who exercises wants to get the most out of their workout. One of the ways that many people do this is by taking a pre workout supplement. These supplements claim that they can help improve your workout. However, many pre workout supplements contain a mystery blend of ingredients from creatine to guarana. The question is, do these supplements work? Are they safe to take?

When choosing a pre workout supplement it is important to do some research on the product, including reading reviews. There are some pre workout supplements that contain dangerous and illegal substances including amphetamine like stimulants. Other supplements contain only legal ingredients, but have high levels of caffeine, which can be harmful to the heart as found by a recent study.

Caffeine Rush

There have been several studies that have shown that taking caffeine before working out can provide a boost. For example, a study conducted by the Journal of Strength Conditioning in 2012 found men who took a caffeine supplement before their workout could perform heavy lifting at higher weights than men who took a placebo.

There have been other studies that show that runners can increase their aerobic capacity when they take caffeine supplements. However, the studies also noted that caffeine benefits wane once individuals develop tolerance.

It is important to note the amount of caffeine in a pre workout supplement. While most contain caffeine, it is important to make sure that the amount is safe to use. It is also important to only use the recommended dosage listed on the product.


Another ingredient found in most pre workout supplements is creatine. Creatine seems to help boost energy production in cells of the muscles and draw fluids from plasma to the skeletal muscles. This can improve overall muscle performance.

Creatine Powder Bottle

The Journal of Athletic Training conducted a study in 2003 that showed college football players who took a creatine supplement experienced less dehydration and had less cramping than those who took a placebo.

In order to improve performance creatine has to be built up in the body. This means that the supplement must be taken on a regular basis in order to improve performance.

Proprietary Blends And Dangerous Additions

Many pre workout supplements contain proprietary blends. These proprietary blends are the secret formulas that each different supplement has in order to claim that their product is the best. This marketing tactic is one of the ways that companies get around listing actual amounts of ingredients. For example, a product may list creatine as a part of their proprietary blend when the product does not contain enough of the ingredient to truly make a difference.

Another potential risk of using pre workout supplements is that some include dangerous substances. When a proprietary formula is used it is difficult to tell exactly what is in the pre workout supplement. For this reason, it is best to choose a supplement that offers an entire ingredient list so that you know what you are taking is safe to use.

One dangerous ingredient that is often found in these supplements is DMAA or 1,3-dimethylamylamine. This ingredient is not on the list of approved ingredients by the FDA. The good news is that most newer supplements do not contain DMAA. However, a similar amphetamine precursor called beta-methylphenethylamine or BMPEA has been found in several supplements. BMPEA is also not on the approved list from the FDA and is a doping agent that can cause heart issues.
