Sarcopenia is a medical condition. Keep this as general education and refer clinical screening or treatment decisions to qualified clinicians.
Geebs coaching takeaway
The study only matters if it changes a behavior.
For older clients, protein is not just a macro target. It is part of a function plan that should be paired with resistance training when possible.

Questions that cite this source.
Collagen peptide answer
Do collagen peptides build muscle?
Collagen peptides should not be treated like whey protein or a complete muscle-building shortcut. The better practical frame is recovery and connective-tissue context, 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.
