This study investigated 10 weeks of β-alanine (BA) supplementation on changes in cognitive function, mood, and physical performance in 100 older adults (70.6 ± 8.7 y). Participants were randomized into a BA (2.4 g·dThe benefits of β-alanine supplementation have been well-established for the past 15+ years [Animal investigations subsequently demonstrated that β-alanine can cross the blood–brain barrier and increase carnosine content in all brain regions in both young and older rats [The benefits of β-alanine supplementation on functional performance in older adults have been reported in several investigations. These human studies have demonstrated that supplementing with β-alanine can delay fatigue, increase strength, and improve functional performance (e.g., sit to stand) [
