Save $ over B12 Shots

Each diffuser contains 30 servings and each of those servings contains ~133 mcg of vitamin B12. That's 4,000 mcg per diffuser, or 4 times how much B12 you'd find in a typical B12 shot. And like B12 shots, inhalation has shown that it can be a very effective absorption mechanism - in some cases hundreds of times more effectively absorbed than pills.
