Caffeinated chewing gum produces comparable strength and power gains to capsules with fewer side effects in resistance-trained men

Randomized Controlled Trial

Human

2025 Dec

This study found that chewing gum with caffeine works just as well as swallowing a caffeine pill to boost strength and power during weightlifting—even when the gum is chewed only 5 minutes before exercising, not an hour like the pill.

Similar Assertions

For men who regularly train with weights, consuming 4 mg of caffeine per kilogram of body weight through chewing gum has the same effect on strength and power during bench press and squat exercises as taking the same dose in capsule form.

When resistance-trained men consume caffeine through chewing gum instead of capsules, they report less stomach discomfort right after working out and fewer episodes of rapid heartbeat or heart palpitations the next day.
