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.

Non-GMO, non-allergenic emulsifier derived from sunflower seeds

Xanthan GumThickener

Natural thickener from fermented carbohydrates

How to Take It

Take it anytime

No evidence a formula this broad works better at any particular hour. Take it with a meal containing fat — the vitamins A and E in it absorb poorly without one.

With a meal containing fat

On the label

As a dietary supplement, mix one scoop (23 grams) with at least 6 to 8 oz of cold water or your favorite beverage. Scoop included.

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