#Preworkout

Daily use of pre-workout supplements—commonplace among fitness-minded Thais and athletes—may not be as risk-free or effective as many believe, according to recent research and expert guidance. While these supplements are marketed for energy, strength, and performance, relying on them daily can cause diminishing returns, potential health risks, and a dependency that shifts the very nature of exercise motivation, new studies and international experts caution (Verywell Health).

Thailand’s booming fitness culture is mirrored in Bangkok’s bustling gyms and the popularity of national sporting events, making the latest international research highly relevant locally. Many Thais use pre-workouts as powder, drinks, or pills to enhance workouts—sometimes without fully considering the risks or regulations. As global sports nutrition finds its place in the Thai urban landscape, understanding the safety and effectiveness of supplement routines has never been more important.

A new clinical trial published in June 2025 has cast doubt on the widely held belief that caffeinated, protein-based pre-workout supplements offer significant advantages over simpler carbohydrate-based options for those seeking strength and performance gains. The findings, which have generated significant interest and debate among fitness enthusiasts in Thailand and globally, suggest that many popular pre-workout formulas may be no more effective than consuming carbohydrates alone before hitting the gym [MensHealth].
