For muscle recovery and protein intake, this delivers 27g of **Whey Protein Isolate** per 30g scoop — a 90% protein-by-weight ratio, which is excellent for a whey isolate. That 27g per serving puts you right in the 20–40g range shown in research to maximize muscle protein synthesis per meal. You're also getting virtually zero fat and only 1g of carbohydrate.
Whey protein isolate goes through additional filtration to remove most of the lactose and fat, making it a leaner option if you're tracking macros closely. The ion-filtration process used here is designed to preserve protein structure while stripping out extras. At 110 calories per scoop, this is an efficient protein source without unnecessary filler.
One thing to note: this is a pure protein product with no added creatine, amino acids, or digestive enzymes. If your goal is a straightforward, high-purity protein boost after training, it delivers on that. For anything beyond protein, you'll need to supplement separately.

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.
