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.

MaltodextrinBinder

Spikes blood sugar faster than table sugar (glycemic index 85–105). Research links it to gut bacteria changes that may promote intestinal inflammation (Nickerson et al. 2015). Used as a cheap filler — adds nothing beneficial.

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.

ProteaseEnzyme

Class of proteolytic enzymes (typically from Aspergillus niger/oryzae or pineapple/papaya) that break peptide bonds in dietary protein

PotassiumMineral

Essential mineral naturally present in many plant-based supplement ingredients

CocoaFlavor

Common food ingredient used for chocolate flavoring in supplements

Guar GumThickener

Natural thickener derived from guar beans

Mixed TocopherolsAntioxidant

Natural vitamin E used as preservative

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
Space it a couple of hours from Iron and Calcium

On the label

Mix 274g (approx. 5 1/2 scoops) with 700ml of milk or water. For best results, consume 30 minutes post workout or alternatively consume any time throughout the day. Powder settles over time; we recommend weighing for the most accurate measure. This product is intended to be used alongside a varied and balanced diet and a healthy lifestyle.

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