How many studies support Protein Intake?

Multiple systematic reviews, meta-analyses, and expert position papers (including PROT-AGE and ESPEN guidelines) consistently support higher dietary protein intake for preserving muscle mass and function in older adults, particularly to counteract sarcopenia and protect lean mass during weight loss. That's backed by 6 published studies in Vitaebase's database, including 1 meta-analysis, the most recent from 2024 -- a modest but real research base.
