Adding more water to your pre-workout may be the best solution to an upset stomach. It might be helpful to make sure you don't take it on an empty stomach. Be careful not

to take other supplements at the same time you ingest your pre-workout. They may irritate your digestive tract. Consider trying a natural remedy like ginger tea, peppermint, or essential oils.

Many pre-workouts contain a blend of beta-alanine, which prevents muscles from releasing lactic acid, and Niacin (or vitamin B3 which is a fat-blocker). Beta-alanine allows you to perform more reps without feeling so much of

the burn. The side-effect is tingling in the extremities. It is neither a serious nor lasting condition. On the other hand, high doses of Niacin can cause tingling, itchiness, and splotchy red rashes. The

combination of beta-alanine and Niacin can cause great discomfort. If the goal of your workout is to burn fat, you may want to skip the Niacin altogether.

Pre-workout supplements are loaded with caffeine. If you workout in the evenings, be mindful that each person metabolizes it at a different rate. For some, the effects can last three hours. For others,

it could take five hours or more to work itself out of your system. If you cannot adjust your workout time, it may be necessary to extend the duration or

reduce the amount of supplements you take. You might also consider a natural sleep aid like melatonin at bedtime.

Frequently this ailment can be avoided by adding more water to your powdered supplement than the directions specify. Not doing so will cause water to be absorbed through the intestinal walls causing loose stools. This

is a simple fix unless you are just sensitive to caffeine and other chemicals. In that case, traditional pre-workout supplements may not be for you. Opt for products with more natural ingredients.
