How to read this section
- Match % - how closely the study matches this product (not overall scientific quality).
- Evidence type - study design (RCT, review, etc.) and whether it is direct, category-level, or indirect.
- What it found - short summary and quoted extract from the paper metadata. Not medical advice.
Direct product evidenceThis study closely matches this product or its active ingredient.
In plain language
In 12 healthy young men, 29.6 g of whey protein isolate (WPI) raised plasma EAA, BCAA and leucine levels. The WPI with Ingredient Optimized® technology produced significantly higher amino acid peaks at 30‑120 min versus standard WPI, indicating a stronger anabolic signal after a single dose. [1]
What the study reported
Verified extract — not AI generated
“Higher post‑prandial amino acid concentrations suggest enhanced support for muscle repair after workouts.”
How it was used
Consume 29.6 g of the whey isolate powder mixed with ~240 mL water as a post‑exercise shake.
Side effects noted
No adverse events reported in the abstract.
Caveats
Small sample (n=12), short‑term plasma measurements only, no direct muscle mass or performance outcomes.
