The Claim
In adults aged 60–85 years, daily protein supplementation for 3 months combined with resistance training is associated with modest improvements in lean mass and muscle strength, whereas protein supplementation alone is associated with minimal or no improvement in lean mass and muscle strength.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults aged 60 to 85, taking protein supplements daily for three months along with resistance training leads to small increases in muscle mass and strength, while taking protein supplements without resistance training does not produce meaningful changes in muscle mass or strength.
See the scientific wording
In adults aged 60–85 years, daily protein supplementation (specific dosage not stated) for 3 months is likely associated with modest improvements in lean mass and muscle strength when combined with resistance training, but shows minimal or no benefit when used alone.
When older adults lift weights, their muscles become more sensitive to amino acids from protein, which triggers more building of new muscle proteins. Without lifting, the muscles do not respond strongly to extra protein, so little new muscle forms.
What the research says
1 studyFor older adults, taking protein shakes by themselves doesn't do much for muscle, but if they also do strength training, the shakes help them build a little more muscle than training alone.
