Glutathione, when effective at all, may take 4-6 months to show results that often fade after discontinuation
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring protein encoded by the TMSB4X gene and present in virtually every cell in the human body

Foundation Zoomer : broad-spectrum baseline markers including liver enzymes, inflammatory markers, and nutrient status that reflect overall Phase II capacity Cellular Zoomer : measures mitochondrial function, oxidative stress markers, and glutathione status, all of which directly impact GST conjugation and energy-dependent pathways Toxin Zoomer : detects environmental toxins (heavy metals, plasticizers, pesticides) and their metabolites, showing what the body is being asked to conjugate Mosaic OAT (Organic Acids Test) : hippuric acid (glycine conjugation of benzoic acid), pyroglutamic acid (glutathione depletion marker), methylation markers, and mitochondrial intermediates Hepatic Detox Profile : directly measures Phase I and Phase II enzyme activity using challenge substrates (caffeine for CYP1A2/NAT2/xanthine oxidase, aspirin for glycine conjugation, acetaminophen for glucuronidation/sulfation/GST conjugation) Hepatic Function Panel : liver enzymes (ALT, AST, GGT, ALP, bilirubin) that reflect hepatocyte health and biliary function Nutrient Zoomer : measures B12, folate, B6, magnesium, zinc, selenium, cysteine, glutathione, and other cofactors critical for every conjugation pathway Methylation Genetics : MTHFR, COMT, CBS, MTR, MTRR, BHMT, and related SNPs that directly affect methylation conjugation and transsulfuration to glutathione A combination of the Hepatic Detox Profile (functional Phase I/II capacity), the OAT (downstream organic acid metabolites), and the Nutrient Zoomer (cofactor status) provides the most comprehensive picture of conjugation function
