> Applications
Ademetionine Disulfate Tosylate is used by pharmaceutical, veterinary, nutraceutical, and research organizations developing SAMe-containing products. API supply is intended for qualified buyers who will confirm dosage form, market category, stability requirements, label language, and finished-product registration obligations in their own markets.
SAMe formulation research
A 2020 journal study evaluated oral SAMe with Lactobacillus plantarum HEAL9 in a randomized, double-blind, placebo-controlled trial for mild-to-moderate depressive symptoms (Prim Care Companion CNS Disord, doi:10.4088/PCC.19m02578, PMID:32589828, n=90). This supports Ademetionine Disulfate Tosylate API relevance for SAMe formulation and analytical-development programs.
Hepatic-support and nutraceutical development
Buyers typically evaluate assay, related substances, counter-ion profile, water content, residual solvents, hygroscopicity, packaging protection, and stability data before moving from sample quantities to pilot or commercial batches. We supply API or ingredient material only, not finished tablets, sachets, capsules, injectables, or veterinary finished products.
