AlluloseSweetener

Rare sugar (D-psicose), naturally found in trace amounts in figs, raisins, and wheat. ~70% sweetness of sucrose. Absorbed but not metabolized — excreted ~70% unchanged in urine. FDA permits exclusion from 'added sugars' labeling.

Natural FlavorsFlavor

Broad regulatory category of flavor constituents derived from natural sources. Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.

Citric AcidAcidulant

Natural acid derived from citrus fruits

Malic AcidAcidulant

Naturally occurring organic acid found in apples, used as a flavor enhancer and acidulant in supplements

Stevia ExtractSweetener

Zero-calorie natural sweetener extracted from the leaves of Stevia rebaudiana

How to Take It

Best taken in the evening

Often taken at night for relaxation and sleep, but absorption is the same anytime — consistency matters most.
