Clinically Studied Benefits
✓ Corrects B-12 deficiency (hematologic & neurologic) — High-dose oral B-12 was as effective as intramuscular therapy in randomized clinical trials of deficient adults.
NIH/PubMed — Kuzminski, 1998
✓ 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).
NIH/PubMed — Vidal-Alaball, 2005
✓ 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).
NIH/PubMed — Smith, 2010
✓ Cognition in low-folate elders — Three-year folic acid (with adequate B-12) improved memory and processing speed vs placebo (DB-RCT).
NIH/PubMed — Durga, 2005
✓ Stress & mood in healthy but stressed adults — B-complex formulations reduced perceived stress and improved mood/well-being (randomized, placebo-controlled).
NIH/PubMed — Stough, 2014
Additional / Promising Evidence
✓ Homocysteine lowering & major CVD events — Although B-vitamins lower homocysteine, large outcome RCTs did not reduce major cardiovascular events.
NIH/PubMed — HOPE-2, 2006
✓ 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.
NIH/PubMed — Kuzminski, 1998
