Natural Stacks Focus Bites, Melon-Mint, 30 Sugar-Free Pieces

Natural Stacks Focus Bites are chewable supplements designed to support focus and alertness without the jitters associated with caffeine. Each piece delivers 100 mg of enfinity® Paraxanthine, a patented form of paraxanthine that is the primary metabolite of caffeine, along with 10 mcg of Vitamin B12 as methylcobalamin. The manufacturer notes that paraxanthine has a shorter half-life than caffeine and cites preclinical animal model research suggesting it may support dopamine production, while human clinical trials have explored its effects on memory.

This product uses enfinity® Paraxanthine, which the manufacturer describes as clinically tested and patented, and it is third-party tested for quality assurance. The melon-mint flavored bites are sugar-free, sweetened with xylitol, stevia, and monk fruit extract. It comes in a 30-count package, with the manufacturer recommending 1-2 pieces as needed, noting that human studies on paraxanthine often use a 200 mg dose.
