"Ketone Supplements: Potential Pitfalls for Endurance Performance"
A study from McMaster University has found that ketone supplements, which are popular among endurance athletes for their supposed performance-enhancing effects, may actually impair athletic performance. The research showed that athletes experienced slower cycling speeds and increased cardiorespiratory stress after consuming these supplements. This contradicts previous beliefs that ketones can serve as an alternative energy source during exercise. The study, published in the International Journal of Sport Nutrition and Exercise Metabolism, adds to the mixed findings from earlier research and suggests that the use of ketone supplements in sports may need to be reevaluated.
