                                According to the National Institutes of Health, vitamin B12 deficiency can go unnoticed for years, making supplementation a critical consideration for many, especially those on a plant-based diet or over 60. Choosing the right vitamin B12 brand involves more than just picking a product off the shelf; it requires understanding key factors like potency, form, and third-party verification to ensure effectiveness and safety.
