  • 02Because of heterogeneity in study designs, populations, dosing regimens, and outcome measures, no formal risk-of-bias tool or quantitative meta-analysis was applied. [Muacevic Alexander (2026)]
  • 03Compared with synthetic caffeine, guayusa has been associated with smoother stimulant effects, possibly due to theobromine’s longer half-life and its vasodilatory properties [,,]. [Muacevic Alexander (2026)]
  • 04Despite this widespread use, most commercial formulations rely almost exclusively on synthetic caffeine as their functional backbone []. [Muacevic Alexander (2026)]
