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

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

Add 3.3 g powder (one 5 cc level scoop) daily in a half cup of hot water, stir well and cool down with cold water or your favourite juice, or as recommended by a physician

General guidance based on the ingredients, not a substitute for the label or your doctor.
