High effect
Caffeine · 200 mg
Caffeine can acutely improve exercise performance, most consistently in endurance activity, while strength and sprint responses vary. The declared amount contributes to this effect, but fixed serving amounts are only approximate comparisons because body mass is unavailable. The supplied evidence does not establish an individualized effective dose or an extra benefit from other accompanying ingredients.

Impact
High effect
Caffeine · 200 mg
Caffeine can produce a modest, short-lived rise in resting metabolic rate. This product supplies 200 mg per serving, but the comparison does not mean that twice a lower studied amount produces twice the benefit. Repeated use and lasting effects are not established by one serving, and acute thermogenesis does not demonstrate durable fat loss.
How this product is rated for Metabolism Support
Ingredient fit92
Caffeine supplies the product's counted contribution, with full amount allowance in the saved comparison.
Goal fit
Caffeine is the sole credited ingredient; the product is also linked to other goals.

Impact
High effect
Caffeine · 200 mg
Caffeine can improve short-term alertness and attention by blocking adenosine signalling. The 200 mg serving receives full amount recognition in the saved comparison, but higher comparison recognition is not proof of more work completed. Timing, tolerance and sleep loss can change its practical effect, and the evidence does not establish sustained occupational productivity.
