The current RDA for protein, set at 0.8 g/kg of body weight, may be falling short of what’s needed for optimal health—especially for older adults. As we age, maintaining muscle mass becomes crucial for staying active, independent, and reducing the risk of age-related injuries and conditions.
Research suggests 1.2–1.6 g/kg daily (0.54–0.72 g/lb) is far more effective for preserving muscle mass and preventing frailty. For older adults, consuming at least 1.2 g/kg of protein daily has been shown to lower the risk of frailty by 30% compared to those who stick to the outdated RDA. Muscle loss (sarcopenia) becomes a real challenge with age, but the right protein intake can make a significant difference. Higher protein consumption not only helps retain strength and mobility but also supports better recovery from illnesses and injuries.
A little adjustment can lead to stronger muscles, better health, and an improved quality of life as we age.
