What this trial studies

The trial examines four supplement combinations over six weeks in endurance- and strength-trained women aged 18-45. Participants are randomly assigned to whey protein, whey protein with adaptogens, plant protein, or plant protein with adaptogens and will take their assigned product daily while keeping their training and diet constant. Measurements before and after the intervention will assess muscle strength, recovery, stress, sleep, and overall wellbeing. The adaptogenic blend consists of ashwagandha root extract and shatavari root extract. The study is conducted at Strength and Nutrition Ltd in Brighton with lead sponsorship from Sports Performance and Applied Research in Trials and Analysis.
