Pea vs. whey: which protein boosts metabolism best?
NCT ID NCT06045611
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how different proteins—from peas, whey, and faba beans—affect metabolism in 28 healthy women aged 18-45. Participants drank protein shakes on separate days, and researchers measured growth hormone and other markers in their blood. The goal is to understand which protein sources have the strongest effects on metabolism.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Isolated pea, whey, and faba bean proteins
- What this could lead to
- If successful, this could help people choose proteins that best support metabolism and growth hormone release.
- What could go wrong
- This is a small, early-stage study in healthy women only. Results may not apply to other groups or lead to direct health advice.
