Discover the precision of anhydrous caffeine in convenient tablets. This caffeine supplement contains only caffeine and microcrystalline cellulose, so you know exactly what you're taking. For anyone who prefers a standardized intake rather than coffee or energy drinks.
Anhydrous caffeine (1,3,7-trimethylxanthine) is a methylxanthine alkaloid. In the central nervous system, it binds as a competitive antagonist to adenosine A1 and A2A receptors, temporarily blocking adenosine's inhibitory signaling. This modulates dopaminergic and noradrenergic neurotransmission and inhibits phosphodiesterase, leading to an increase in intracellular cAMP. The biochemical properties of anhydrous caffeine are identical to those of caffeine from natural sources; the distinction lies primarily in the anhydrous and standardized form.
After oral intake, anhydrous caffeine is absorbed rapidly and almost completely; peak plasma concentrations typically occur within 30 to 60 minutes. Bioavailability is comparable to that of coffee or tea, but tablets provide a consistent amount with each dose. The biological half-life averages 3 to 7 hours, determined in particular by CYP1A2 activity and individual factors.
Compared to coffee or energy drinks, anhydrous caffeine does not contain associated plant substances such as chlorogenic acids or polyphenols. Tea often provides L-theanine in addition to caffeine; this combination is not present in this product. Compared to powders or capsules, tablets offer the same active substance, but differ mainly in excipients and dosage consistency.
In summary: anhydrous caffeine is the same 1,3,7-trimethylxanthine as in coffee and tea, but in an anhydrous and standardized form. Thanks to the solid tablet form, the amount per dose can be precisely determined.
Contains pure anhydrous caffeine (1,3,7-trimethylxanthine) with a consistent composition per tablet. The minimalist formulation keeps the contents transparent: only the active substance and microcrystalline cellulose.
200 mg per tablet, within the commonly used range of 100-400 mg in the literature. This allows for precise dosing when standardization is desired.
The annual format offers a favorable quantity-to-cost ratio per dose compared to smaller packaging. The fixed dosage per tablet also ensures a consistent intake without unnecessary extras.
Suitable for a vegan and gluten-free lifestyle. With 365 tablets per pot, you have a long-lasting supply without needing to reorder frequently.

Anhydrous caffeine is the dehydrated and standardized form of the same molecule found in coffee and tea. Chemically, it is identical to caffeine; the difference lies in its solid, anhydrous form and the precisely dosed amount per tablet.
After consumption, plasma peaks are generally reached in 30 to 60 minutes. The half-life of caffeine averages between 3 and 7 hours, but this varies from person to person. Genetic variation, smoking, pregnancy, liver function, and certain medications can influence its elimination.
Many people choose to take them in the morning or early afternoon. Avoid caffeine late in the day and make it a rule to wait at least 6 hours before bed. Also, consider your total caffeine intake from other sources.
Caffeine sensitivity varies greatly from person to person and depends on body weight, tolerance, and genetic factors. If you are not used to caffeine, pay particular attention to your total intake from coffee, tea, and other beverages.
Caffeine acts as a competitive antagonist at adenosine A1 and A2A receptors. The substance crosses the blood-brain barrier and is mainly metabolized in the liver by CYP1A2, particularly into paraxanthine.
The active molecule is the same in all cases, but the tablets provide a pre-measured and standardized amount. In coffee or energy drinks, the amount of caffeine varies from one serving to another and is accompanied by other components such as acids, sugars, or polyphenols.
