Comparing PeptiStrong with Low Dose Whey to High Dose Whey Protein Alone for Muscle Function in Adults 60 to 85 Years

What this Trial Is About

Researchers are investigating the effects of two protein drinks on muscle function in healthy older adults aged 60 to 85 years. The study compares a standard whey protein drink containing 20 grams of protein with a lower dose drink containing 10 grams of protein, combining whey protein and PeptiStrong, a fava bean hydrolysate with bioactive peptides. The goal is to understand whether the lower protein drink with PeptiStrong can lead to similar or better improvements in physical function, inflammation, fatigue, and quality of life compared to the standard whey protein drink. Participants will be randomly assigned to one of two groups one group will consume a drink with 2.4 grams of PeptiStrong plus 8.4 grams of whey protein daily, totaling 10 grams of protein, while the other will receive 20 grams of whey protein daily. Both protein drinks are provided as dry powders to make a drinkable shake. The study duration is 30 days, during which participants consume their assigned protein drink once daily. During the study, participants will attend two visits at the research facility, one at baseline and another at the end of the study. Researchers will measure hand grip strength, chair stand performance, walking speed, balance tests, and endurance. They will also assess quality of life, fatigue levels, inflammatory markers from blood tests, and body composition. These evaluations occur from the start to the end of the 4-week period to monitor changes and effects of the protein supplements on muscle health and function.
