Yogurt vs. milk: which packs a better protein punch?
NCT ID NCT07243730
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to see if yogurt or milk provides essential amino acids (the building blocks of protein) more quickly after eating. Thirty healthy adults will consume either yogurt or milk on two separate visits, and blood samples will be taken over several hours to measure amino acid levels. The results could help people choose the best dairy option for protein absorption.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- full fat yogurt and full fat pasteurized milk
- What this could lead to
- If it works, this could help understand which dairy product provides better protein absorption, potentially guiding dietary recommendations.
- What could go wrong
- This is a small, early-stage study in healthy volunteers, so results may not apply to people with health conditions. It measures short-term blood levels, not long-term health outcomes.
