Disregard the purveyors of pseudoscience (like a recent reviewer) who claim there are toxic elements used in this Vitamin. The B12 used in this product is perfectly safe and although the amount is higher than the RDI (recommended daily intake), it is none the less perfectly safe. Whatever your body doesn’t absorb will be filtered out in the bathroom,” writes a shopper.
