Evaluating Metabolic Health in People Aged 18 to 60 by Nutrilite Metabolic Health Index

The goal of this observational study is to evaluate Metabolic Health by fit analysis between calculated Nutrilite Metabolic Health Index and the result of Metabolomics analysis from blood plasma samples in healthy adult participants aged between 18 and 60 years. The main question it aims to answer: \- Does the Nutrilite Metabolic Health Index fit well with the result of Metabolomics analysis from blood plasma samples? 200 eligible participants will be enrolled in a single center, one site visit will be made to finish a health questionnaire, a lifestyle questionnaire, a routine physical checkup. Blood samples will be collected for routine blood test (blood sugar, total triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, uric acid), and for Metabolomics testing. Researchers will calculate the Nutrilite Metabolic Health Index based on participant data, and do the fit analysis against the result from Metabolomics analysis.
