Targeted Supplementation and Nutritional Strategies for Healthy Aging: A Review of Physiological and Molecular Benefits
Protein and mitochondrial-support supplements consistently improve muscle and cell energy in aging studies, though longer trials are needed before widespread recommendations.
This narrative review synthesizes evidence from 32 human studies on nutritional compounds targeting aging pathways, finding consistent support for protein/collagen supplementation for muscle mass and emerging evidence for mitochondrial-support compounds (NAD+ precursors, glycine+NAC). Evidence is predominantly short-term and heterogeneous — longer trials needed before clinical recommendations.
