Do protein supplements help if you already get enough protein? Protein matters for maintaining muscle. But more protein is not automatically better. A 2025 overview of thirty-three meta-analyses found that routine protein supplementation did not improve muscle mass, strength, or physical performance in healthy older adults overall. The picture was more favorable in some people with long-term health conditions, and when supplementation was combined with exercise. So if you already meet your protein needs through food, a shake may be convenient, but it is not automatically an upgrade. A supplement can make more sense when intake is low, appetite is poor, recovery raises nutrition needs, or convenience helps you consistently reach your target. And if kidney disease, significant illness, or unintended weight loss is involved, individual medical guidance matters. This was Health IN60seconds. One question. One minute. One useful answer.
