SA experts warn about gym supplement toxicity
Medical experts from the University of Cape Town are calling for stricter regulation of pre-workout supplements due to the risk of methylxanthine-mediated toxicity. They highlight that these products often contain undisclosed or inaccurately labeled stimulants, which can lead to severe health complications.
Why it matters

In a letter to the SAMJ editor, J Taylor, G Tatz, N Madikizela and M Blockman write:

Marketed as exercise performance enhancers, these are often sold as proprietary blends with incompletely disclosed ingredients, and frequently contain stimulants such as caffeine and theobromine .
