Chewing gum with caffeine works as well as pills for lifting — and gives you fewer stomach issues
Caffeinated chewing gum produces comparable strength and power gains to capsules with fewer side effects in resistance-trained men

Surprising Findings
Caffeine gum produced identical strength and power gains to capsules despite being absorbed 12x faster (5 min vs. 60 min).
It’s widely assumed that slower absorption (via gut) leads to better or more sustained effects—this study proves rapid oral absorption is just as effective for strength and power.
Practical Takeaways
Switch from caffeine capsules to chewing gum 5 minutes before your heavy lifting session for the same strength and power boost—with less stomach upset and no heart palpitations.

Taking caffeine before exercise may make the experience more enjoyable, but it does not cause muscles to grow larger or stronger over time.
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.
Taking 4 mg of caffeine per kilogram of body weight, whether in gum or pill form, increases the maximum strength and power output during bench press and squat exercises in men who regularly train with weights, compared to taking a placebo.
Chewing gum containing caffeine can improve muscle strength during weightlifting if taken just 5 minutes before exercise, and this effect is similar to taking caffeine in capsule form an hour earlier.
Taking caffeine before lifting heavy weights can increase the power generated during exercises like the back squat and bench press, with the largest gains occurring when lifting at 75–90% of maximum capacity.
