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.
Rebaudioside MSweetener
High-purity steviol glycoside (Reb M) used as a natural high-intensity sweetener with minimal aftertaste
How to Take It
Best taken in the evening
Take at night. Other amino acids compete for brain uptake, so a protein-heavy meal blunts it. Take it between meals, away from food.
On an empty stomach
Keep it away from protein-heavy meals
Space it a couple of hours from SAMe
On the label
1 scoop with 12-14 fluid ounces of preferred liquid, as needed, to reach optimal daily protein intake.
Do not combine with St. John's Wort
Each of these raises serotonin activity on top of St. John's Wort, and together they can trigger serotonin syndrome — agitation, rapid heartbeat, raised blood pressure. Not without medical supervision.
General guidance based on the ingredients, not a substitute for the label or your doctor.
