What Are Vitamin B12 Diffusers & How Do They Work?

Starting in the early 1950s, doctors and scientists have demonstrated that inhalation is a safe and highly effective way to administer B12. This was shown to be true not only in the general population, but also for patients that did not respond to oral supplementation since they lacked the ability to readily absorb it in their stomach. The inhalation of B12 showed positive results for the patients in each trial [1,2,4].

Our Breathe B12 diffusers vaporize B12, allowing consumers to inhale the vitamin daily. B12 is a vitamin that is not affected by heat, and therefore the diffuser does not affect the integrity of the vitamin.

Is daily diffuser inhalation an effective way to absorb B12?

Yes. Studies show that the inhalation of B12 is a highly effective way to receive the necessary amount needed to bring patients out of a vitamin deficient state [1,2,4]. The results of the studies showed that inhaling the vitamins, using several different methods, showed similar results to intramuscular injections. This bioavailable form of B12 makes it a vegan-friendly method for those who choose a vegan or vegetarian diet and want to boost their B12 daily intake.


Our own internal research with vitamin B12 diffusers (we tested with cyanocobalamin, but the newer methylcobalamin is even more effective) confirms efficacy with once-a-day use.

The data is strong — it really works! — using Breathe shows extremely rapid B12 absorption into the blood, though individual results may vary. Athletes and others who want to increase their endurance and energy levels have a choice of methods to take B12 including lozenges and sublingual drops, patches, gummy vitamins, nasal sprays, and injections. Make an informed decision about the best B12 supplement for you, but w think the science behind our diffuser/vaporizers is clear upon direct comparison.

Why choose a diffuser over injections or pills?

If injections and diffusers both have superior efficacy relative to pills. So why choose one over the other? The two main differences between these products are convenience and cost.

How much your B12 shots cost varies depending on your dosage, location, insurance, and supply. Not to mention, the cost of doctor visits for a prescription of vitamin B12 vials, and clinic visits for the administration of the shots if you aren’t self-administering the injections.

The Breathe B12 diffuser is a pain-free (and fun!) way to administer the same amount of liquid B12 for a fraction of the cost. For less than $20 per inhaler, you get 30 servings of 333 mcg. Save yourself some time, money and inconvenience, and try out Breathe B12 and enjoy the benefits today.
