It does not act as aggressively as charcoal or clay, but it offers supportive, gentle binding alongside nutritional replenishment
Briefly, 5 L of biofluid samples or serial dilutions of a chemical standard library of 149 metabolites were extracted with 45 L of a 75:25:0.1 HPLC grade acetonitrile:methanol:formic acid extraction mix that included the following labeled stable isotope internal standards: 13 C-labeled yeast extract (Cambridge Isotope Laboratory, Andover, MA, ISO1), 2 H 9 choline (Cambridge Isotope Laboratory, Andover, MA, DLM-549), 13 C 4 3-hydroxybutyrate (Cambridge Isotope Laboratory, Andover, MA, CLM-3853), 13 C 6 15 N 2 cystine (Cambridge Isotope Laboratory, Andover, MA, CNLM4244), 13 C 3 lactate (Sigma-Aldrich, Darmstadt, Germany, 485926), 13 C 6 glucose (Cambridge Isotope Laboratory, Andover, MA, CLM-1396), 13 C 3 serine (Cambridge Isotope Laboratory, Andover, MA, CLM-1574), 13 C 2 glycine (Cambridge Isotope Laboratory, Andover, MA, CLM-1017), 13 C 5 hypoxanthine (Cambridge Isotope Laboratory, Andover, MA, CLM8042), 13 C 2 15 N taurine (Cambridge Isotope Laboratory, Andover, MA, CNLM-10253), 13 C 3 glycerol (Cambridge Isotope Laboratory, Andover, MA, CLM-1510) and 2 H 3 creatinine (Cambridge Isotope Laboratory, Andover, MA, DLM-3653)
Comment: Many commenters indicated that they oppose the proposals to replace the estimated allowed amount with the median allowed amount and add the 10th and 90th percentile allowed amounts due to the burden they place on hospitals
