Your body stores and uses vitamin B12 over time, so it is important to combat deficiency with injections as soon as possible

Studies have shown that regular oral supplementation is just as effective as having B12 injections (Masucci and Goeree, 2013)

Weekend breaks on the oral route are a cost choice, not a studied protocol

It is not for human consumption, veterinary use, or medical applications
