Registry check · Betaine HCl
Does anyone independently verify Betaine HCl supplements?
1 of the 6 Betaine HCl products on this page is confirmed in NSF/ANSI 173: Thorne Betaine HCl & Pepsin (225ct). For the others, the listing may name a certification, but we did not find it in a public registry — that is not evidence against them, only an absence of independent confirmation.
Certification is not a dosing guarantee. Across the whole catalogue, certified products reach the clinically studied dose 57% of the time and uncertified ones 71% — a gap too small to mean anything (Fisher p = 0.185). Read the Betaine HCl dose column either way.
The 6 products on this page checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
