Other Ingredients (7)

FD&C Red No. 40 LakeColorant

Same petroleum-derived azo dye as Red 40, linked to hyperactivity in children (Southampton study) and carrying an EU warning label; pure cosmetic color with zero benefit.

SucraloseSweetener

Dose context matters. As a trace excipient in a tablet coating or capsule, the amount is minimal and not a meaningful concern. The evidence below applies to the gram-level intakes typical of sweetened protein powders, pre-workouts, and drink mixes: a 2022 human trial (Suez et al., Cell) showed sucralose disrupts gut bacteria and worsens blood sugar control in healthy adults, and a 2023 study (Schiffman et al.) found that sucralose-6-acetate — a compound formed when sucralose is digested — was genotoxic to human cells in vitro. It remains an artificial sweetener with no nutritional purpose.

Artificial FlavorsFlavor

Composition is proprietary and not disclosed on the label, so allergens or solvents cannot be verified. Naturally flavored alternatives are more transparent.

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.

Soy LecithinEmulsifier

Widely used emulsifier derived from soybeans

Citric AcidAcidulant

Natural acid derived from citrus fruits

Sunflower LecithinEmulsifier

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

How to Take It

Take it anytime

Total daily protein is what matters — the post-workout "anabolic window" has not held up in controlled trials.

With or without food

On the label

Mix about one scoop of the powder into 6 to 8 fluid ounces of cold water, milk, or other beverage. Stir, shake, or blend until dissolved. For best results, mix up your shake 30 to 60 minutes after your workout or use as an anytime snack in your balanced diet.

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