This is my 2nd bottle of B-12. Last November I was diagnosed with a B-12 deficiency. This required me to travel monthly to my dr's office for an injection. Last Feb I purchased my 1st bottle of B12 and after about 6weeks my blood test showed my B12 levels were up. Only one spray daily is required. I've saved gas money, a dr's office visit, no more waiting in the dr's office 30min or more for an injection. I am very glad I found this product.
