If your goal is muscle recovery and meeting daily protein targets, you're getting a solid 30g per scoop from a blend of **Whey Protein** concentrate, isolate, and hydrolyzed whey. That's a strong single-serving dose — most clinical studies on muscle protein synthesis use 20-40g of whey per serving, putting this right in the effective range.
The added micronutrients are minimal. **Vitamin D** at 25mcg (1,000 IU) is within the clinical range for bone and immune support, but **Zinc** is provided as zinc oxide — the poorest-absorbed form — and **Vitamin C** at 90mg as ascorbic acid covers your RDA but falls below supplemental doses used in research.
At 180 calories per scoop with 8g of carbs, this is not a lean isolate — you're getting more filler per gram of protein than a pure whey isolate would deliver. The artificial sweeteners (sucralose, acesulfame-K) and maltodextrin are worth noting if you prefer to avoid those ingredients.

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.
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 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.
Ascorbic AcidAntioxidant
Vitamin C used as an antioxidant preservative in supplements to prevent oxidation
Calcium CarbonateBuffer
Common calcium salt used as a buffering agent, filler, or mineral fortification in supplements
CholecalciferolVitamin
Vitamin D3 added in trace amounts for fortification in protein powders and other supplements
CocoaFlavor
Common food ingredient used for chocolate flavoring in supplements
