Carlson’s account, verified against the raw fetched text of the HistoryNet article, records that LeBlanc marketed Hadacol “as a balm for vague ailments like indigestion, insomnia, and irritability” (Carlson 2018), a framing consistent with the tonic’s actual B-complex-vitamin, iron, and mineral content (Gisclair 2018). Correcting a real, diagnosed vitamin deficiency is genuine medicine, and this is the narrowest, most defensible version of Hadacol’s marketed promise. But no source in this bundle documents that Hadacol’s customers were screened for or shown to have an actual vitamin deficiency, or that any clinical study measured symptom relief in Hadacol users against a control. The claim is logged endpoint_type: surrogate (relief of nonspecific symptoms, not a diagnosed condition) and verification_status: unreplicated, distinct from the separately logged, more serious disease-cure claims this same marketing was built to support.
