Paraxanthine powder, also known as 1,7-Dimethylxanthine, is a metabolite of caffeine with a similar structure to caffeine. It also occurs naturally in some foods, such as coffee beans, cocoa fruits, and citrus flowers.
Is paraxanthine stronger than caffeine?
Both have similar stimulating effects, and paraxanthine is safer than caffeine based on in vitro and in vivo clinical studies. It is primarily a major metabolite of caffeine, accounting for about 70% of caffeine intake, and it accounts for about 80% of the amount of caffeine broken down in the liver.

What does paraxanthine do to your body?
1. Paraxanthine has been shown to have many of the same nootropic benefits as caffeine, including improved cognition, short-term memory, sustained attention, and cognitive effects in animal models of Parkinson's disease.
2. In addition, paraxanthine is thought to have beneficial effects on physical endurance and athletic performance.
3. 1,7-Dimethylxanthine also has similar cardiovascular, hormonal, and metabolic effects as caffeine.
4. Both caffeine and paraxanthine act as antagonists of adenosine receptors A1 and A2A. However, paraxanthine appears to exhibit superior binding potency to equine forebrain adenosine A1 and A2A receptors, resulting in a stronger motor activation effect in horses.
5. Paraxanthine causes much less DNA damage and is less cytotoxic.
1. As a novel ingredient in food and beverages.
2. As a functional ingredient in supplements.
