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.
Stevia ExtractSweetener
Zero-calorie natural sweetener extracted from the leaves of Stevia rebaudiana
How to Take It
Best taken in the evening
Magnesium citrate pulls water into the bowel — mildly laxative at higher doses. Evening suits that; split the dose or switch to glycinate if it's too much.
With or without food
Space it a couple of hours from Iron and Calcium
On the label
Individual needs may vary. Start with approximately a half-teaspoon (1 g) daily and gradually increase to 2 teaspoons (4 g). For best results, divide the daily amount into 2 or 3 portions per day, taken with or without food.
General guidance based on the ingredients, not a substitute for the label or your doctor.
