Caffeine Gum

Caffeine delivered through the cheek lining, which gets it into the blood faster than capsules. The ergogenic effect is the familiar caffeine effect; the gum's advantage is timing convenience, not a bigger benefit.

What the science says

Improves exercise performance Moderate evidence
A systematic review and meta-analysis of caffeine chewing gum trials found small to moderate improvements in endurance and some sprint outcomes versus placebo. Individual trials are small crossover studies in trained participants.
Faster absorption than capsules Moderate evidence
Pharmacokinetic studies found caffeine from chewing gum appears in plasma markedly faster than from capsules, with similar overall bioavailability. This allows dosing closer to the start of exercise, roughly 5–10 minutes rather than 60.
Effects on strength and jumping are less consistent Limited evidence
A 2026 systematic review and meta-analysis of caffeinated gum for muscular strength, endurance and jumping found effects were smaller and less consistent than for aerobic outcomes. Do not expect a strength breakthrough from the delivery format.

Dosage & safety

Studied doseStudies typically used 100–300 mg (about 3 mg/kg), chewed for 5–10 minutes and started roughly 5 minutes before exercise.

SafetySame profile as any caffeine: insomnia, anxiety, tremor, raised heart rate and blood pressure. Avoid late in the day, keep total intake under about 400 mg/day for adults and 200 mg/day in pregnancy, and avoid stacking with other caffeinated products. Some formulas add sugar alcohols that can cause gut upset.
