Guarana powder is used as a plant source of caffeine. Caffeine content depends on the product. Grams of powder are therefore not the same as the amount of caffeine contained; ‘natural’ does not automatically mean mild either.
Alertness is not every kind of performance
Caffeine stimulates the central nervous system and can increase alertness. Guarana studies found small reaction-time benefits in some cognitive tasks, but no consistent general performance gain. How much is attributable to caffeine or other ingredients remains unclear. Feeling more awake proves neither muscle growth nor better sleep or long-term health.
The caffeine amount must be clear
Check the amount per serving and the specific product’s recommended use. Include coffee, tea, energy drinks, other supplements and caffeine-containing medicines in the total intake. Without reliable content information, do not estimate an amount using a generic spoon rule. Do not add concentrated caffeine powder or other stimulants without appropriate oversight.
Consider sleep and individual sensitivity
Caffeine can cause restlessness, anxiety, sleep problems, palpitations and increased blood pressure. Late intake can disrupt sleep even if you feel accustomed to the stimulating effect. Health-based guidance values for healthy adults are not a personal target dose or blanket approval for people with medical conditions or taking medicines.
Seek professional advice beforehand if you have cardiovascular disease or pronounced anxiety, are pregnant or breastfeeding, or are considering use in children or adolescents. Seek immediate medical help for chest pain, fainting, breathing problems or severe persistent racing heartbeat. If an overdose is suspected, keep the packaging available and contact medical help or a poison information service without delay.
