Natural Caffeine Anhydrous
Also known as: Caffeine, Anhydrous Caffeine, Caffeine Anhydrous
Overview
Caffeine anhydrous is a dehydrated form of caffeine, chemically identical to regular caffeine but without water content. It is a naturally occurring stimulant found in plants like coffee beans, tea leaves, cocoa, guarana, and yerba mate. It is commonly used to enhance alertness, improve athletic performance, and aid in weight loss. Caffeine anhydrous is highly bioavailable with rapid absorption and a half-life of approximately 3 to 5 hours. Research on caffeine's effects is extensive, with numerous systematic reviews and meta-analyses available, though specific studies on anhydrous forms may be limited. It acts primarily as an adenosine receptor antagonist, influencing neurotransmitter activity and enhancing alertness.
Benefits
Caffeine anhydrous significantly improves athletic performance, as indicated by a meta-analysis showing a standardized mean difference (SMD) of 0.82 (95% CI: 0.27, 1.37; P = 0.003). It also enhances alertness and cognitive function. Potential neuroprotective effects against diseases like Alzheimer's and Parkinson's have been suggested, though more research is needed. Athletes and individuals seeking weight loss may benefit most from its stimulant effects. The effects typically begin within 30 minutes and peak within 1 to 2 hours after ingestion.
How it works
Caffeine anhydrous primarily acts as an adenosine receptor antagonist, particularly blocking A2A receptors, which influences neurotransmitter activity and enhances alertness. It affects the central nervous system, cardiovascular system, and metabolic pathways. Its known molecular targets are adenosine receptors, particularly A2A and A1 receptors. Caffeine is highly bioavailable (99%) with rapid absorption in the small intestine.
Side effects
Common side effects of caffeine anhydrous include jitters, anxiety, insomnia, increased heart rate, and stomach upset. Uncommon side effects include headaches, dizziness, and nausea. Rare side effects may include seizures and heart arrhythmias in susceptible individuals. It may interact with certain medications like antidepressants and increase the risk of bleeding when combined with anticoagulants. It is contraindicated in pregnancy, breastfeeding, and certain cardiovascular conditions. Children, older adults, and individuals with pre-existing medical conditions should consult healthcare providers before use.
Dosage
The minimum effective dose of caffeine anhydrous is typically around 50-100 mg for cognitive effects. Optimal dosage ranges are 200-400 mg for athletic performance enhancement. The maximum safe dose is generally not to exceed 400 mg per day for healthy adults. It is best taken 30 minutes to 1 hour before desired effects, often used in capsules or tablets. Absorption is not significantly affected by food intake.
FAQs
How much caffeine is safe?
The maximum safe dose is generally considered to be 400 mg per day for healthy adults.
What are the safety considerations?
Caffeine can interact with certain medications and exacerbate conditions like high blood pressure. Consult a healthcare provider if you have concerns.
When is the best time to take it?
It is best taken in the morning or early afternoon to avoid disrupting sleep patterns.
What results can I expect?
You can expect enhanced alertness and improved athletic performance with appropriate dosing.
Is caffeine anhydrous different from regular caffeine?
Caffeine anhydrous is not chemically different from regular caffeine; it is simply dehydrated, resulting in a more concentrated form.
