Correction: The earlier article said dietary supplements were not regulated by the FDA. That was inaccurate. Regulation and approval before sale are different matters.

What FDA oversight means

FDA regulates dietary supplements, but generally does not approve supplements or their labels before they are marketed. Manufacturers have responsibilities for safety and labelling, and FDA can take action on unlawful products. See FDA's supplement questions and answers.

Evaluate the actual product

“Pre-workout” is a marketing category, not a single formula. Read the ingredients, amounts and warnings rather than assuming every product has the same effects. Ask a qualified healthcare professional about use alongside medicines or an existing condition.

Avoid misleading comparisons

The old article used protein-shake consumption as a proxy for pre-workout usage. Those categories are not interchangeable, so that comparison has been removed. Claims about how many people use a product should identify a survey that actually measured that product.
