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.
Acesulfame PotassiumSweetener
Older NTP rodent studies (1980s, contested) reported lymphoma and leukemia at very high chronic doses; modern reviews (FDA 2003, EFSA 2000) concluded no cancer risk at human exposure levels but the issue is not fully resolved (Mishra 2020 review). Animal evidence suggests gut microbiome disruption (Bian 2017 — male mice on Ace-K showed altered microbiota and metabolic markers). Manufacturing uses methylene chloride, with potential residue concerns. Purely cosmetic additive — risk:benefit unfavorable for supplements.
Natural and Artificial FlavorsFlavor
The 'artificial' component means synthetic chemicals are used, but the exact compounds are proprietary and not disclosed on the label. If you have sensitivities or allergies, you cannot verify what's in it. Products using only natural flavors are more transparent.
Beta-Carotene (color)Color
Beta-carotene used in small amounts as a colorant/antioxidant.
Citric AcidAcidulant
Natural acid derived from citrus fruits
Malic AcidAcidulant
Naturally occurring organic acid found in apples, used as a flavor enhancer and acidulant in supplements
How to Take It
Take it anytime
No evidence a formula this broad works better at any particular hour. Take it with food — the potassium in it is what makes this kind of product feel nauseating on an empty stomach.
With food
Space it a couple of hours from Iron and Calcium
On the label
Suggested use: For intra-workout, mix 1-2 scoops (1-2 servings) with 20-40 ounces of cold water. Drink approximately 1/3 of mix 20 minutes prior to intense training, then sip the remainder throughout your training session. As a peri-workout, use pre, intra or post training to enhance endurance and recovery.
