The review
Why we put this on the shelf.
Cyanocobalamin (the cheap form of B12 in most multivitamins) requires the body to convert it before it can be used — a step many people, especially older adults and those with MTHFR variants, do poorly.
Thorne uses methylcobalamin — the form your body actually uses, no conversion required. 1mg per capsule is a clinical dose.
Essential if you're vegan, vegetarian, over 50, on metformin, or take acid-reducing meds — all of which dramatically lower B12.
