What the brand says

**Buy 2 Sprays And Get Your Shipping Refunded** QB12 delivers 500 mcg of vitamin B12 per serving to ensure a safe yet beneficial dosage. Studies show the body absorbs the amount of vitamin B12 from an oral supplement based on his or her needs. Because vitamin B12 is not absorbed easily in dietary delivery methods, QB12 uses a spray delivery method for optimal efficacy.
