How we verify

The brand submits the formula. We read the supplement facts panel and weigh dose, form and synergy against the clinical evidence. Labs test. IngredientMD verifies. The fee pays for review time, never for the outcome.

How we read this product

Source: Supplement facts
Supplement Facts panel for Pro Performance Whey Protein 24g
  1. 01
    We read the label.

    The panel on the left is the one we evaluated, line by line.

  2. 02
    Every active, separately.

    All 2 actives checked against the clinical evidence: dose, form, and what the research actually shows.

  3. 03
    Then the formula as a whole.

    Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "Backed by human trials".

  4. 04
    Earned, not bought.

    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.

In context

The gap this formula speaks to.

Public health figures the engine matched to this formula's ingredients. Reported by their source, cited and dated, never written by the brand.

The people it speaks toFieldwork 2023

21.1% of the US population

aged 15 and over took part in sports, exercise, or recreation on an average day in 2023, in the American Time Use Survey.

Systematic review and meta-analysis, 2024
BCAAs

Meta-analysis, 2026

A Bayesian network meta-analysis of protein and amino acid supplements found small improvements in exercise performance and post-exercise recovery markers, with the size of the effect depending on the supplement type.

Journal of the International Society of Sport
BCAAs

Randomised trial, 2025

In this trial, branched-chain amino acid supplementation shifted substrate use during exercise, improved exercise efficiency and lowered self-reported muscle soreness after training compared with placebo.

Nutrients
BCAAs

Randomised trial, 2025

Examined whether the timing of branched-chain amino acid intake around resistance training affects recovery measures in healthy men. The comparison is timing, so it does not address whether supplementation beats no supplementation.

American Journal of Men's Health
BCAAs

Randomised trial, 2025

Dileucine-supplemented essential amino acids supported whole-body anabolism after resistance exercise and stimulated protein synthesis in serum-stimulated cell work. The intervention is a leucine derivative within a full essential amino acid blend, not a 2:1:1 branched-chain product.

Journal of the International Society of Sports Nutrition
BCAAs

Randomised trial, 2026

High-leucine branched-chain amino acid supplementation was reported to reduce the loss of ultrasound-measured quadriceps thickness in hospitalised adults. Muscle thickness on ultrasound is a structural marker, not a measure of strength or function.

Clinical Nutrition ESPEN
BCAAs

Randomised trial, 2025

A hospital trial tested branched-chain amino acids given by IV drip as an add-on under clinical supervision, a very different exposure from an oral supplement.

What this formula earned

Every one of these is a fact the engine could ground.

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.

Studied alongside this brand's other formulas

Where two of this brand's products carry actives the literature has read together, the pairing and its basis are below. The evidence word is the corpus row's own confidence, never a score.

Pro Performance Whey Protein 24g + Mega Men MultivitaminEstablished

Riboflavin supplies the FAD carried by the E3 subunit of the branched-chain ketoacid dehydrogenase complex and by the acyl-CoA dehydrogenases downstream. It sits inside the same enzyme machinery.

FAD cofactor of the dehydrogenase complex. No combination trial has tested this exact pairing.

Pro Performance Whey Protein 24g + Mega Men MultivitaminEstablished

NAD+ takes the electrons from the branched-chain ketoacid dehydrogenase reaction, and niacin is its precursor. The complex requires thiamine, lipoate, FAD and NAD together.

NAD acceptor for the dehydrogenase step. No combination trial has tested this exact pairing.

Pro Performance Whey Protein 24g + Mega Men MultivitaminEstablished

3-methylcrotonyl-CoA carboxylase in leucine breakdown is biotin-dependent. Leucine metabolism runs through a biotin enzyme regardless of ratio.

cofactor for a carboxylase in the leucine route. No combination trial has tested this exact pairing.
