Protein supplementation does not significantly augment the effects of resistance exercise training on muscle mass or strength in older adults (≥70 years) compared to resistance exercise alone.
If you are over 70 and doing resistance training, you do not need to buy protein supplements to get better results. The research shows that getting protein from food is just as effective as supplements for building muscle and strength in this age group. Focus on eating enough protein overall rather than spending money on powders.
Contrary to previous reviews, evidence from 15 studies (n = 917 participants) indicated no evidence of an effect of supplementation.
Why this rating
