Short answer: Maca Root & Guarana are included to support energy and metabolic activity — a specific, named pairing distinct from the formula's blood-sugar-focused ingredients.
Why these two are grouped together specifically
Both address the formula's steady-energy claim directly, though through genuinely different mechanisms — Maca traditionally for stamina, Guarana specifically for its caffeine content.
Why Guarana specifically requires a separate caution
Guarana contains natural caffeine, so those sensitive to stimulants should take note — a direct, specific flag distinguishing this ingredient from the rest of the formula.
⚠️ Worth knowing: if you are sensitive to stimulants or caffeine, or manage high blood pressure or a heart condition, please take this into account and speak with your doctor.
