Recommended doses vary, but in general, 500 mg to 2 g per day is recommended for healthy people
Response: We understand commenters' concern regarding the timing around removal of these measures and the confusion and burden this may impose on hospitals and ASCs that have already submitted CY 2024 quality data
Long-term supplementation with 3-5 grams daily achieves the same results over time
QC report including TIC RSD across QC injections Processed feature matrix: aligned peak list with retention time, m/z, adduct assignment, and per-sample intensity values Differential feature results: volcano plot (fold change vs FDR), feature lists stratified by annotation confidence level (MS1 only / MS1+MS2 / MS1+MS2+RT) Annotated metabolite table: HMDB accession, metabolite name, chemical class, pathway class, biosample annotation confidence KEGG pathway enrichment map: ranked pathways by impact score and FDR, colour-coded by direction of perturbation (enriched up vs down) Multivariate analysis plots: PCA scores plot (all samples), OPLS-DA S-plot and permutation test for compound MoA separation experiments MoA interpretation report: written mechanistic summary translating pathway findings into drug mechanism hypotheses, with off-target and toxicity pathway flags Compound comparison matrix (Mode 2): inter-compound metabolic fingerprint similarity scores and mechanism-class cluster dendrogram Representative Results Volcano plot: metabolome-wide drug response features Full-feature volcano plot from RP-LC-HRMS untargeted metabolomics, comparing compound-treated versus DMSO-vehicle control cells (n = 6 per group)
Methods: Thirty-six rats were allocated to six groups, one control group and five MTX groups, where induction of hepatotoxicity was achieved via injecting MTX (20 mg/kg)
