Frequently Asked Questions


How do I use each disposable inhaler?
Open the packaging, remove the silicone tips and inhale from the end with two air holes. There is no button or anything else you need to do. Take 5-10 puffs per day. There is 1mg of vitamin B12 (methylcobalamin) in each inhaler which is the equivalent of 1 vitamin B12 injection. When it runs out, throw it away or recycle it.

What devices are compatible with the 30ml liquids?

You can use any refillable device with our 30ml liquids. Simply take off the lid and follow the instructions on your hardware device manual. Each 30ml liquid has 30mg of Vitamin B12. The 30ml liquids are 25x the size of the disposable inhalers.

How do I know when it’s out?

You won't be able to to inhale any of the vitamin formula.

Is inhaling Vitamin B12 really that much better than taking pills?
A direct quote from an academic, peer-reviewed paper on the subject tackles this question:

“To further evaluate the efficacy of pulmonary absorption of the inhaled B12 over and above the evidence afforded by the clinical and hematological response previously described, urinary excretion studies were performed. Upon oral administration of B12 at dosages as high as 10,000 mcg B-12 activity in urine has been shown to be less than 0.05 millimicrograms/ml. After inhalation of only 200 mcgm of B12 in saline, B-12 activity in the urine reached the level of 0.26 millimicrograms/ml and following inhalation of approximately 500 mcgm of B12 in a lactose powder B12 activity in the urine rose to 0.134 millimicrograms /ml. Direct pulmonary instillation of 100 micrograms of crystalline vitamin B12 by means of the bronchoscope resulted in a urinary excretion (9.76 millimicrograms/ml.) pattern equivalent to the intramuscular injection of 60-80 mcgm.”

F.J. Smith, R.W. Monto, J.W. Rebuck, “B12 Inhalation Therapy in Pernicious Anemia,” Trans Am. Clin. Climatol. Assoc. Vol. 64, p. 27 (1953).

These measurements imply that inhalation can be order(s) of magnitude more absorbent than pills. 

Why is Vitamin B12 so important?

According to the National Institute of Health: “Vitamin B12 is a nutrient that helps keep the body’s nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Vitamin B12 also helps prevent a type of anemia called megaloblastic anemia that makes people tired and weak.” The UK Vegan Society, the Vegetarian Resource Group, and the Physicians Committee for Responsible Medicine, among others, recommend that vegans either consistently eat B12-fortified foods or take a daily or weekly B12 supplement to meet the recommended intake. In other words, getting enough vitamin B12 is very important.

But I read on the Internet you can’t inhale vitamins?

A couple of our competitors have been rightly called-out for selling products that contain numerous vitamins that can’t be effectively diffused. The reason for this is the RDI (recommended daily intake) of these other vitamins is so high that you wouldn't receive an adequate dose of each vitamin. However, vitamin B12 is an ideal candidate for diffusing as the RDI is much smaller; the inhalation science goes back half a century. The studies found that inhaling B12 was both safe and very effective. We recommend reading the primary academic literature on our science page.

Can I take too much B12?

According to WedMD “Even at high doses, vitamin B-12 seems fairly safe. Experts have not found a specific dose of vitamin B12 that’s dangerous. No tolerable upper intake levels have been set.”

How long will it last?

Each inhaler is designed to last 3-4 weeks of daily use as directed. We estimate around 800 breaths in each inhaler, this is each to the individual user as each persons breaths are different. The 30ml liquids are 15x the size of the disposable devices. One 30ml bottle can last well over 6 months.


Are Inhale Vitamins products safe?

According to the existing research on B12 inhalation:

“This simple form of therapy is not only effective, but safe and economical.”

R.W. Monto & J.W. Rebuck, “Nasal Instillation and Inhalation of Crystalline Vitamin B12 in Pernicious Anemia,” AMA Arch Intern Med. Vol. 93, p. 219 (1954).

“There was no evidence of irritation at the time of inhalation. I personally examined the patients’ chests periodically, and I was not able to determine abnormal signs in the lungs. In addition to the clinical examination, we obtained periodic roentgenograms of the chest and they showed no change.”

“Inhalation of crystalline B-12 in physiological saline or lactose powder has, to date, produced no objective or subjective evidence of toxicity or sensitivity at the pulmonary site.”

F.J. Smith, R.W. Monto, J.W. Rebuck, “B12 Inhalation Therapy in Pernicious Anemia,” Trans Am. Clin. Climatol. Assoc. Vol. 64, p. 27 (1953).

    Does vitamin B12 really give me energy?

    Low B12 levels are often associated with fatigue. Taking B12 in those cases can be very beneficial for energy, but what about everyone else? Many swear by B12 as an energy aid, it is a primary ingredient in products like 5-Hour-Energy, but the science is unclear that B12 can be used as an energy aid for people who are not low on B12 to begin with. Customers that have lower B12 levels are the ones that should see the most energy benefit from using our products. Others may not see much of a difference at all.

    Who shouldn’t use Inhale Vitamins?

    Anyone with a sensitivity to any of the listed ingredients, cobalt, nickel, or vaporising in general should NOT use Inhale Vitamins. Please consult your doctor for any health-related questions. 

    Do your inhalers contain Vitamin E?
