Daily supplementation with 38 g/day of lactic acid bacteria–fermented whey protein (LAB-FWP) led to significant improvements in physical performance, including an increase in electronic Short Physical Performance Battery (eSPPB) scores (P = .034) and hand grip strength (P = .043).
Practitioners may consider recommending LAB-FWP supplementation to improve physical performance in older adults.
