Caffeine anhydrous is a stimulant alkaloid often used to support alertness, energy and motivation during daily activities and workouts. This form is a concentrated, anhydrous caffeine source picked for fast absorption and synergistic effects with other ingredients in the blend.

What Does Caffeine Anhydrous Do? Caffeine helps raise metabolic rate and boost energy availability during activity, contributing to heightened thermogenesis and fat oxidation as part of a broader activity plan, with effects seen when used alongside other thermogenic ingredients. Dr. Astrup at the University of Copenhagen found that caffeine boosts thermogenesis. The mix of caffeine with other actives in this product also supports sharper focus and workout drive through its stimulant properties, aligning with EFSA-informed understandings of nutrient function.
