Can a Protein-Adaptogen combo boost strength and cut stress?
NCT ID NCT07716904
First seen Jul 21, 2026 · Last updated Jul 23, 2026 · Updated 2 times
Summary
This trial investigates whether whey protein, alone or combined with the adaptogenic herb ashwagandha, can improve muscle strength, recovery, stress levels, and overall wellbeing in physically active men aged 18 to 45. Participants take either whey protein or whey protein with ashwagandha for six weeks, then undergo strength tests, provide saliva samples, and complete questionnaires. The goal is to see if adding ashwagandha offers extra benefits beyond protein alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- whey protein with or without ashwagandha root extract
- What this could lead to
- If successful, this could point toward an optimal supplement strategy for improving muscle recovery and reducing stress in active individuals.
- What could go wrong
- This is a small, early-stage trial with only 60 participants, so results may not apply to all athletes or the general population. The effects may be modest or not statistically significant.
