The Future of Nootropic Caffeine

AmaTea® Max Organic Guayusa Extract

Not all caffeine is equal. AmaTea® Max comes from Guayusa (Ilex guayusa), hailed as an Amazonian “super leaf” thanks to exceptional antioxidant properties and unique caffeine content. We developed a patented extraction process to enhance the plant’s naturally occurring compounds to provide a nootropic ingredient that delivers a bright, balanced, and cognitively uplifting energy experience. Numerous peer-reviewed journals have published articles on this impressive ingredient’s efficacy and safe use. However, for added peace of mind, AFS hired an independent lab to conduct its safety data and submit it to the FDA for review, receiving a historical first “no questions letter” recognizing its GRAS status for safe usage in food and beverage applications.

Guayusa is technically very different than other teas in that it lacks a heavy tannin or bitter fraction that would typically cause the astringent, dry-chalky flavor profiles. Instead, guayusa provides a pleasant, almost sweet tea-like flavor.

Safety First

Applied Food Sciences achieved a historical first for a natural caffeine-containing botanical when they received a “no questions letter” from the FDA recognizing the safe use of guayusa in approved food and beverage applications through its GRAS analysis (Generally Recognized as Safe).
