Clinically Studied Benefits (with research)
- PMS symptom support — Systematic review of randomized trials concluded vitamin B-6 (up to 100 mg/day) is likely beneficial for premenstrual symptoms and premenstrual depression. (Wyatt 1999, BMJ, PMC)
- Nausea of early pregnancy (NVP) — Double-blind RCTs show pyridoxine significantly reduces nausea severity versus placebo. (Sahakian 1991, PubMed; Vutyavanich 1995, PubMed)
- Anxiety/stress (selected adults) — Randomized trial found high-dose B-6 reduced self-reported anxiety versus placebo over one month. (Field 2022, PMC)
- PMS improvement vs comparators — Recent randomized trial compared B-6 to a micronutrient formula for PMS; both groups improved with signals favoring broad micronutrients, supporting B-6’s role in PMS care. (Retallick-Brown 2020, PubMed)
Promising/Traditional (with human data & limitations)*
- Carpal tunnel syndrome* — Human trials are mixed: one RCT found no advantage for B-6 over conservative care, while another reported symptom improvement; overall evidence remains inconsistent. (Stransky 1989, PubMed; Talebi 2013, PubMed; review Ryan-Harshman 2007, PMC)
- Homocysteine & cardiovascular outcomes* — B-vitamins (including B-6) lower homocysteine, but large outcome RCTs found no reduction in major cardiovascular events. (HOPE-2, NEJM 2006)
University & Global Studies (Human — PubMed/PMC-Linked)
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.*
