Purcaf Organic Caffeine
Also known as: PurCaf Organic Caffeine, Organic Caffeine, Green Coffee Caffeine, Caffeine
Overview
Caffeine is a naturally occurring stimulant widely found in coffee beans, tea leaves, and cacao pods. PurCaf Organic Caffeine is sourced from organic green coffee beans using a clean-water extraction method. It is a USDA Certified Organic product, Non-GMO Project Verified, and recognized as safe (GRAS). Caffeine is used primarily for enhancing mental clarity, focus, and physical performance, especially during exercise. Research backs its ergogenic effects on physical performance and cognitive improvements, making it a well-studied ingredient with significant applications in both athletic and cognitive enhancement contexts.
Benefits
Caffeine has been shown to provide multiple benefits, including: 1. **Exercise Performance**: Enhances aerobic endurance, muscle strength, endurance, and jumping performance, supported by systematic reviews indicating moderate to high methodological quality of findings. 2. **Cognitive Function**: Improves mental clarity and alertness, though specific quantified details vary. Evidence indicates enhancements in attention and reaction time. 3. **Energy and Stamina**: Increases overall physical performance and stamina for workouts and daily activities. 4. **Population-Specific Benefits**: Has notable application in preterm infants for treating apnea, despite potential side effects like tachycardia. Effects manifest within 30-60 minutes of ingestion and can last for several hours, varying based on dosage and individual metabolism.
How it works
Caffeine operates primarily as an adenosine receptor antagonist, which decreases the effectiveness of adenosine, a neurotransmitter that promotes sleep and relaxation. This antagonist action increases the availability and activity of neurotransmitters like dopamine and norepinephrine, which enhances alertness and cognitive function. In terms of physiological effects, caffeine also boosts muscle contraction force and metabolic rate, impacting central nervous, cardiovascular, and muscular systems, with reliable absorption leading to peak effects within 1-2 hours.
Side effects
Caffeine is generally recognized as safe (GRAS) when consumed at moderate levels (up to 400 mg/day) for healthy adults. Common side effects (affecting >5% of users) include jitters, anxiety, insomnia, increased heart rate, and gastrointestinal disturbances. Uncommon effects (1-5%) can be headaches, dizziness, and nausea, while rare side effects (<1%) may involve severe allergic reactions, arrhythmias, or seizures. Caution is advised for individuals with pregnancy, nursing, and certain medical conditions (e.g., high blood pressure, heart disease). Drug interactions can reduce the effectiveness of some medications, especially antidepressants. Specific populations like premature infants can experience tachycardia and feeding intolerance when given caffeine for apnea.
Dosage
Recommended dosages for caffeine vary based on desired effects: - For cognitive enhancement, a dose of 50-100 mg is often sufficient. - For exercise performance, optimal dosages range from 200-400 mg, taken about 30-60 minutes before physical activity. - The typical maximum safe dose for healthy adults is 400 mg per day. Timing is important, with recommendations to take caffeine in the morning or early afternoon to prevent sleep disturbances. Forms of caffeine include powders and capsules, ensuring full water solubility for optimal absorption. Individual metabolism can affect absorption rates, but food intake does not significantly alter it.
