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.

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.

FlaxseedFood

Ground or whole flaxseed added as a food-based carrier and fiber source.

InulinFiller

Prebiotic soluble fiber from chicory root, used as a filler and flow agent in capsules and tablets

OatsFood

Whole oat grain or oat flour used as a food base or filler.

ProteaseEnzyme

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

Whey ProteinProtein Source

Common dairy-derived protein that sometimes appears in the other ingredients list due to label parsing

Xanthan GumThickener

Natural thickener from fermented carbohydrates

How to Take It

Best taken in the morning

Contains caffeine — keep it to the morning. Take with food; high-dose EGCG on an empty stomach stresses the liver.

With food

Glutamine does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.

Keep it away from iron-rich meals
Space it a couple of hours from Iron

On the label

Mix 60g (approx. 2 scoops) with 300ml of water or milk in a shaker, shake well and consume anytime 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.
