What is a common side effect of pre-workout supplements?

While vomiting can occur as a side effect of pre-workout supplements, a more commonly reported side effect is nausea. Pre-workout supplements often contain high doses of caffeine and other stimulants, which can lead to stomach discomfort and feelings of nausea, especially if taken on an empty stomach.

This type of discomfort can frequently deter individuals from using these supplements effectively. Issues arise particularly when users are not accustomed to such high stimulant levels or when they exceed recommended dosages. Nausea can also be exacerbated by other ingredients, such as beta-alanine, which might cause a tingling sensation that could be misinterpreted as sickness.

Despite some users experiencing vomiting, it is less frequent compared to the consistent reports of nausea following the use of these products. Other options like mental fatigue and weight loss are generally not directly associated with the immediate impact of pre-workout supplements.
