Honest limits
What this study does not prove.
Sarcopenia is a medical condition, so screening and treatment decisions belong with qualified clinicians.
Kris's practical takeaway
Here's what to do with it.
For older adults, protein is not just a macro target. It can support daily function when paired with resistance training.
Ways to use it
Safe ways to apply it.
Protein is aging infrastructure
Whey is a tool, not the whole plan
Keep strength in the protein conversation

Questions this research helps answer.
Collagen peptide answer
Do collagen peptides build muscle?
Collagen peptides are not the same as whey protein and are not a complete muscle-building shortcut. Their evidence fits recovery and connective-tissue questions better, while muscle growth still depends on progressive training, total protein, calories, and sleep.
Protein timing answer
Does protein timing matter for muscle?
Protein timing can matter at the margins, but most regular people should fix total daily protein first. A consistent protein floor beats panic about a perfect post-workout window.
Protein supplement answer
Which protein supplement is best for muscle?
The best protein supplement is the one that helps you hit total protein while training hard. Supplement rankings are less important than the base pattern: consistent lifting, enough daily protein, and meals you can repeat.
Protein source answer
Is plant protein as good as animal protein for muscle?
Plant protein can work, but the plan may need more precision. Total protein, source variety, protein quality, and resistance training matter more than arguing about one perfect food.
