BioStacksCaffeine and energy
Caffeine is a supporting nutrient for energy support. Caffeine is the world's most widely consumed psychoactive substance and one of the most extensively studied ergogenic aids. A 2018 umbrella review of meta-analyses confirmed significant improvements in muscular endurance, strength, anaerobic power, and aerobic endurance. Cognitive effects include improved alertness, attention, and reaction time at doses as low as 100 mg. In clinical studies, caffeine enhances physical and mental energy.
How much caffeine do you need
Research points to 100–400 mg as the effective range for caffeine. FDA considers 400 mg/day safe for most adults. Ergogenic studies use 3–6 mg/kg body weight. Cognitive benefits at 100–200 mg. Lower doses may provide some benefit, but most studies showing clear results used this range.
