Clinically Studied Benefits (with research)
- Corrects B-12 deficiency (hematologic & neurologic) — High-dose oral B-12 was as effective as intramuscular therapy in randomized clinical trials of deficient adults. (Kuzminski 1998, RCT — PubMed; Cochrane Review 2018 — PMC)
- Raises serum B-12 & improves functional markers — Oral high-dose cobalamin increased serum B-12 and reduced methylmalonic acid/homocysteine versus low dose/placebo (randomized evidence). (Vidal-Alaball 2005, RCT synthesis — PubMed)
- Homocysteine & brain atrophy (MCI subgroup) — In older adults with mild cognitive impairment and elevated homocysteine, folate+B-6+B-12 slowed whole-brain atrophy vs placebo (double-blind RCT). (Smith 2010, PLoS One — PMC)
- Cognition in low-folate elders — Three-year folic acid (with adequate B-12) improved memory and processing speed vs placebo (DB-RCT). (Durga 2005, The Lancet — PubMed)
- Stress & mood in healthy but stressed adults — B-complex formulations reduced perceived stress and improved mood/well-being (randomized, placebo-controlled). (Stough 2014 — PMC)
Promising/Traditional (with human data & limitations)*
- Homocysteine lowering & major CVD events* — Although B-vitamins lower homocysteine, large outcome RCTs did not reduce major cardiovascular events. (HOPE-2 2006 — PubMed)
- Chewable/sublingual delivery* — Oral (including high-dose chewable/sublingual) B-12 is effective for deficiency; head-to-head outcome advantages over standard oral forms are limited in current human trials.
We monitor research from the world’s leading institutions — including Harvard, Johns Hopkins, Mayo Clinic, Cleveland Clinic, Cambridge University, Oxford, Stanford, Yale, MIT, the University of Florida, Oregon State University – Linus Pauling Institute, Tufts, Boston University, Cornell, Columbia, and Ohio State — to ensure our guidance remains aligned with the highest standards of credible science.*
