NHANESWhey Protein Isolate is the lead active here, studied most for strength. In the Protein Blend with two others, listed first. Potassium is the most studied active here, with 16 human studies behind it, each one cited. Who it fits: for everyone, adults.
Verified by IngredientMDThe panel on the left is the one we evaluated, line by line.
All 6 actives checked against the clinical evidence: dose, form, and what the research actually shows.
Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "Backed by human trials".
The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.
Read by the engine against 2.1 million data points from clinical trials, PubMed and more than a hundred vetted sources. No individual reviewer is named or implied.
Cross-checked against 1,301 documented interactions for these actives.
Public health figures the engine matched to this formula's ingredients. Reported by their source, cited and dated, never written by the brand.

Cohort study, 2015Randomised trial, 2025
A leucine-enriched beta-lactoglobulin preparation was compared with an isonitrogenous whey protein isolate for skeletal muscle protein synthesis, a stable-isotope marker measured over hours rather than a change in muscle size.
NutrientsSystematic review, 2026
Across the trials reviewed, whey and soy protein supplementation alongside resistance training in young adults was associated with changes in training adaptations, with the authors noting variability between studies.
Journal of Dietary SupplementsSystematic review, 2025
Supplementation with milk proteins was reviewed for effects on body composition and anthropometric measures, with results varying by the training and dietary context of the underlying trials.
NutrientsRandomised trial, 2026
Reports blood cholesterol and related lipid measures with oral whey protein concentrate and with its hydrolysates. Circulating lipids are markers and the two preparations are reported separately because processing changes the peptide profile.
Clinical Nutrition ResearchRandomised trial, 2025
Co-ingesting an oral microbial protease with whey protein changed postprandial plasma amino acid concentrations. Plasma appearance is a marker of digestion and absorption rate, not a measure of muscle protein accrual.
The Journal of NutritionRandomised trial, 2025
Reports postprandial plasma amino acid and appetite ratings when whey or pea protein was added to a low-protein breakfast. Amino acid curves and appetite scores are markers taken over hours, not body composition outcomes.
European Journal of NutritionSystematic review, 2026
Long-term plant and animal protein supplementation were compared for body composition, muscle strength and physical performance. The review did not detect a clear separation between the two sources, which is a failure to detect a difference rather than evidence that they perform identically.
Frontiers in NutritionRandomised trial, 2019
Whey protein isolate taken during endurance training did not produce a detectable change in cycling performance or the immune measures recorded, which is a failure to detect a difference and not evidence that none exists.
Frontiers in NutritionRandomised trial, 2026
Animal and plant protein supplements shifted gut microbial makeup and its predicted metabolic potential, a computational estimate of capability, not a measured effect.
NutrientsSystematic review, 2025
A review looked at early protein intake in infancy and later body weight and metabolic measures in children, finding associations across cohorts rather than a demonstrated cause.

Each line below was derived from this formula's own record at the time of verification. Nothing here was written by the brand, and nothing can be added that the evidence does not carry.
Time-to-effect windows the engine read from the trial record. Each is a window a named study measured, cited and dated, never written by the brand.
In a randomised crossover trial, 12 healthy men aged 19 to 32 consumed 29.6 g of whey protein isolate, with plasma amino acids sampled at 30, 60, 90, 120 and 180 minutes after the dose. Essential amino acids, branched-chain amino acids and leucine all rose significantly from baseline in both arms. The trial's comparison was between a processed isolate and the standard form.
A randomised cross-over trial in ten women of mean age 69 gave a single 500 mg dose of calcium as citrate fasting, citrate with a meal, fortified juice or a dairy product meal, with blood drawn before and at 1, 2, 4 and 6 hours. Serum ionised and total calcium increased significantly from baseline over six hours, with the rise similar after fortified juice, delayed when citrate was taken with a meal and smaller after the dairy meal. A separate double-blind cross-over trial in 25 postmenopausal women measured parathyroid hormone and a bone resorption marker 12 hours after a single calcium dose. Ten participants is a small sample, and what moved was blood chemistry, not a sensation.

Six ingredients, from each one's own page.
Muscle protein synthesis lifts within an hour or two of a serving. Change you can see in strength and body composition tracks weeks of training with enough total protein.
The amino acid rise happens inside an hour. Strength and lean mass changes are read at eight to twelve weeks in most trials, alongside resistance training.
Plasma amino acids peak within about an hour of a serving. The training results build across weeks, and most trials read them at eight to twelve weeks.
Plasma amino acids rise within about 30 minutes of drinking it, faster than with intact protein. Changes in muscle repair and body composition are measured over weeks.
No acute sensation. Parathyroid hormone responds within hours, while bone density shifts over a year or more of steady intake, so this reads on a panel and a scan.
Cramp steadiness and hydration can shift within a day or two of raising intake. The blood pressure side, within the normal range, reads out over four to six weeks.
How each ingredient usually behaves over time, from its own page on IngredientMD. General timing for the ingredient, not a measurement of this product.
It is a powder, so the serving scales to the amount you want and mixes into something you already drink.
