Buying Guide
- Potency and form: If you want 2,000 mcg specifically, look for lozenges or microtablets labeled 2000 mcg. Some brands offer 2500 or 3000 mcg as alternatives; choose based on your daily target and tolerance for higher doses.
- Form and bioavailability: Methylcobalamin and adenosylcobalamin are active coenzyme forms that some users prefer for better absorption. Cyanocobalamin is a common, stable option; consider your preference for fast-dissolving formats (ActivMelt, microLingual) vs. capsules or softgels.
- Dietary considerations: For vegetarians or vegans, verify vegan or vegetarian certifications and ensure the product is dairy-free, gluten-free, and allergen-friendly if needed.
- Delivery format: If you dislike swallowing pills, lozenges or dissolvable tablets offer easier administration. Water-free sublingual formats can improve convenience and absorption for some individuals.
- Allergens and certifications: Check for nut-free, kosher, or other certifications that matter to you. Some products also market no sugar or sugar-free formulations, which can be important for certain diets.
- Storage and shelf life: Softgels versus lozenges can differ in shelf life and storage needs. Store in a cool, dry place away from light to preserve potency.
