Malnutrition affects around half of older adults in care homes and one third living independently, accelerating muscle loss, increasing fall risk, and compounding the physiological vulnerability that defines frailty. Standard protein and energy recommendations alone are often insufficient when nutritional deficit is already established.
This hub covers guideline-aligned nutritional management of frailty, the clinical evidence for muscle-targeted oral supplementation combined with exercise, and the case for repositioning nutrition as a primary intervention across acute and chronic disease in older patients.

Frailty in older adults is driven by the convergence of inactivity, malnutrition, and sarcopenia, conditions that are closely interrelated and mutually reinforcing. Sarcopenia prevalence reaches up to 76% in rehabilitation settings among patients with malnutrition, making nutritional status a direct predictor of muscle health trajectory.
Early screening is the critical first step, enabling targeted intervention before functional decline becomes entrenched. Muscle-targeted oral nutritional supplements containing whey protein, leucine, and vitamin D have demonstrated efficacy in increasing muscle mass, strength, and physical performance in patients with sarcopenia, providing a specific, evidence-based tool beyond standard dietary advice.

Neither protein supplementation nor functional exercise alone produces consistent improvements in frail older adults. A clinical trial in nursing home residents aged 75 and over examined the combined effect of sit-to-stand exercises and protein-rich oral nutritional supplementation over 12 weeks, with outcomes measured across physical function, body composition, and nutritional status.
Overall results were modest, but subgroup analysis showed that residents with high adherence to both the exercise and supplementation components achieved gains in fat-free mass, weight stability, and maintained functional performance. The findings highlight adherence as the key determinant of outcome, with direct implications for how combined interventions are designed and monitored in long-term care settings.
Muscle mass and function decline under combined pressure from ageing, acute illness, and inadequate protein intake. In older adults, this trajectory is further complicated by conditions such as cancer, where treatment-related catabolism compounds age-related muscle loss and creates a clinical picture that standard care pathways are not designed to address.
A proactive, multidisciplinary nutritional approach, centred on adequate protein provision and timed alongside physical rehabilitation, is associated with reduced disability onset and better recovery trajectories. The evidence now supports treating targeted nutritional support not as adjunctive care, but as a primary clinical strategy for preserving autonomy in frail and at-risk older patients.
