Description of intervention(s) / exposure
The treatment group will receive oral capsule of 500mg of Cosmos caudatus extract (1 capsule per day) for 12 weeks. Weekly telephone calls will be done to monitor adherence and to address the concern of subjects such as presence of any side effects after consuming Cosmos caudatus supplementation. Compliance will be monitored by the researcher by asking the subjects to return the supplement bottle every month.

Statistical methods / analysis
Data will be analysed using Statistical Package for the Social Sciences (SPSS) version 26 (SPSS Inc, Chicago, USA). For continuous data, it will be presented in mean ± SD whereas categorical data presented in percentage. Normality test will be done using Shapiro-Wilk test prior to univariate analysis. For baseline analysis, the difference of study outcome between the sarcopenic treatment and control group will be compared using independent t-test. The effectiveness of the Cosmos caudatus supplementation will be assessed using the two-way repeated measure ANOVA adjusted for possible confounding factors. The significance level (a) will be set at 0.05 while the confidence level is at 95% for the test and p-value <0.05 will be considered significant

Summary
Brief summary
Sarcopenia is one of the most prominent issues that may restrain healthy aging among older adults. Cosmos caudatus is high in vitamin C and bioactive compounds. To date, no studies had used Cosmos caudatus as an intervention for sarcopenic older adults. Therefore, this study is done to address the research gap which is a double-blind placebo controlled randomized trial conducted to investigate the effects of 12 weeks of Cosmos caudatus supplement on dietary intake, cognition, mental health, sleep quality, disability and protein synthesis pathways among older adults with sarcopenia. A total of 64 older adults diagnosed with sarcopenia will be enrolled. Intervention group will be received 500 mg/day of C. caudatus supplementation while the placebo group will be given 500 mg/day of maltodextrin. Sarcopenia will be assessed using the Asian Working Group of Sarcopenia (AWGS) 2019. Study outcomes such as dietary pattern, physical fitness, sarcopenia indices, anthropometric data, mental health, disability and sleep quality will be measured at baseline, 6th week and 12th week. A total of 5 ml blood will be taken for protein synthesis pathways using the IGF/Akt/mTOR pathway and metabolomics at the baseline and 12th week. Fecal sample will be collected from a subsample of 24 subjects (12 from each group) for gut microbiota analysis. Analysis will be conducted using descriptive analysis, univariate analysis and two-way repeated measure ANOVA. The findings from this study hope to be able to give significant proof of the effectiveness of Cosmos caudatus as a nutraceutical product for older adults with sarcopenia.
