Whey protein with or without an adaptogenic blend for physically active men

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The trial compares two supplement regimens in physically active men aged 18-45 who train at least three times weekly. Participants are randomized to receive either whey protein alone or whey protein plus an adaptogenic blend containing 600 mg ashwagandha root extract for six weeks. They undergo pre- and post-intervention testing, complete recovery, sleep, stress, soreness, and digestive health questionnaires, and provide saliva samples to measure stress-related biomarkers. The study aims to determine if adding ashwagandha to whey offers additional benefits beyond protein alone for strength, recovery, sleep, and wellbeing.
