Clinically Studied Benefits (with research)
- Corrects B-12 deficiency (hematologic & neurologic) — High-dose oral B-12 is as effective as intramuscular therapy in randomized trials of deficiency. (Vidal-Alaball 2005, PubMed; Cochrane 2018, PMC)
- 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 (DB-RCT). (Smith 2010, PLoS One, PMC)
- Cognition in low-folate elders — Three-year folic acid supplementation improved memory and information processing (DB-RCT). (Durga 2005, 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; Kennedy 2010, PubMed)
- Neurologic support with adequate B-6/B-12 status — Trials highlight roles in neurotransmitter synthesis and nerve function within multi-B interventions. (Stough 2014, PMC)
Promising/Traditional (with human data & limitations)*
- Homocysteine lowering & CVD outcomes* — B-vitamins lower homocysteine, but large outcome RCTs did not show reduced major cardiovascular events. (HOPE-2 2006, PubMed)
- Fatigue/energy in generally healthy adults* — Some RCTs report improved subjective energy/stress; effects vary by baseline status and formulation. (Stough 2014, PMC)
- Biotin for brittle nails/skin* — Open-label human data suggest nail thickness improvements; controlled evidence is limited. (J Am Acad Dermatol 1993, PubMed)
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.*
