Losing muscle is a common worry for older adults. It makes daily tasks harder and increases the risk of falling. A new analysis looked at how different foods and supplements might help. The team examined data from 3,063 elderly patients who had sarcopenia, which is the medical term for age-related muscle loss. They tested anti-inflammatory diets and various supplements to see what worked best. The results showed clear winners for different measures of health. For example, whey protein was the most effective way to improve handgrip strength. This is a simple measure of how strong your hands are. Vitamin D helped the most with walking speed. Another specific compound called epicatechin helped build muscle mass. The five times sit-to-stand test also showed improvement when people took combined supplements. This test measures how quickly someone can stand up and sit down five times. It is a key sign of overall physical function. The study suggests that personalized nutrition plans are needed. Each person has different needs, so one size does not fit all. The researchers recommend developing strategies that target the specific needs of patients with sarcopenia.

Key Takeaway
Consider that whey protein, vitamin D, and epicatechin may improve specific sarcopenia outcomes, but personalized strategies are needed.
This is a systematic review and network meta-analysis of anti-inflammatory diets and supplements for elderly patients with sarcopenia, synthesizing evidence from 3063 participants. The authors compared combined supplements, amino acids, whey protein, beta-hydroxy-beta-methylbutyrate, vitamin D, n-3 polyunsaturated fatty acids, and epicatechin.
Key findings indicate whey protein was the most effective measure for improving handgrip strength (SMD=0.78, 95% CI: 0.07, 1.48). Vitamin D was most effective for gait speed (SMD=1.44, 95% CI: 0.76, 2.11), and epicatechin was most effective for appendicular skeletal muscle mass index (SMD=2.44, 95% CI: 1.69, 3.18). Combined supplements showed significant improvement in the five times sit-to-stand test (SMD = -0.34, 95% CI: -0.63, -0.05).
The authors acknowledge limitations, including that follow-up duration and safety data were not reported. No specific gaps in the evidence were detailed in the provided information.
Practice relevance is restrained, with a recommendation to develop personalized and multi-target nutritional intervention strategies based on patient needs.

BACKGROUND & AIMS: Dietary anti-inflammatory interventions have shown promise in the prevention and management of sarcopenia. However, the efficacy of various anti-inflammatory diets/supplements in improving muscle strength, mass, and physical performance in patients with sarcopenia remains unclear. The objective of this study was to systematically assess the efficacy of various anti-inflammatory supplements in alleviating symptoms in patients with sarcopenia, thereby providing robust evidence to inform clinical practice and nutritional recommendations.
METHODS: This study systematically searched 11 Chinese and English databases in August 2025 to include randomized controlled trials (RCTs) evaluating the intervention effects of anti-inflammatory diets or supplements on elderly patients with sarcopenia. Primary outcomes included handgrip strength, gait speed, the five times sit-to-stand test (FTSST), and the appendicular skeletal muscle mass index (ASMI). Secondary outcomes included the Short Physical Performance Battery (SPPB) score, fat-free mass (FFM), and laboratory parameters (triglycerides, high-density lipoprotein, low-density lipoprotein, and C-reactive protein). For primary outcomes, both pairwise and network meta-analyses were performed to compare the effects of different interventions. For secondary outcomes, only pairwise meta-analysis was conducted.
RESULTS: Finally, 42 randomized controlled trials were included, involving 3063 elderly patients with sarcopenia, covering seven categories of anti-inflammatory supplements: combined supplements (combinations of at least two anti-inflammatory supplements), amino acids, whey protein, β-Hydroxy-β-methylbutyrate (HMB), Vitamin D, n-3 polyunsaturated fatty acids (PUFAs), and epicatechin. Network meta-analysis results indicated that whey protein (SMD=0.78, 95% CI: 0.07, 1.48), vitamin D (SMD=1.44, 95% CI: 0.76, 2.11), and Epicatechin (SMD=2.44, 95% CI: 1.69, 3.18) are the most effective measures to improve handgrip strength, gait speed, and ASMI, respectively. For FTSST, a significant improvement was only found for combined supplements in the pairwise meta-analysis (SMD = -0.34, 95% CI: -0.63, -0.05). Notably, combined supplements demonstrated positive trends in improving handgrip strength, gait speed, FTSST, and ASMI.
CONCLUSIONS: This study confirms that anti-inflammatory supplements are effective in enhancing muscle strength, muscle mass, and physical function among sarcopenic patients. Combined supplementation strategies were identified as the most favorable intervention for achieving comprehensive improvement. It is recommended to develop personalized and multi-target nutritional intervention strategies based on the needs of patients with sarcopenia.
