Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Every vendor on this page is verified for endotoxin testing — not just HPLC purity.
Evidence base is essentially single-lab (Khavinson, Lezhava, and collaborators). In vitro studies on lymphocyte chromatin in elderly subjects and small Russian reports in chronic gastritis and immune senescence. No FDA-registered clinical trials and no Western RCTs.
