Healthline's top overall B12 pick, Thorne is the gold standard for supplement quality — third-party tested, methylcobalamin form, and trusted by healthcare professionals. Worth the extra cost if quality is your priority.
The top vegan B12 pick from both Healthline and Good Housekeeping, with multiple third-party certifications including certified vegan. Uses methylcobalamin form with an organic produce blend for better real-food alignment.
The go-to for people with food allergies or sensitivities — free from wheat, soy, dairy, eggs, tree nuts, and peanuts, plus certified gluten-free. Healthline recommends it specifically for allergen-sensitive individuals.
At just $0.05 per serving, NOW's B12 lozenges are the most affordable option recommended by dietitians — and they dissolve under the tongue for potentially better absorption than standard pills.
