Vitamin Inhalation Science


Peer-reviewed studies going back over half a century indicate that inhalation is an extremely effective way of absorbing vitamin B12. After only one dose they indicate immediate absorption: 

There are a couple of key reasons that vitamin B12 works so well for inhalation. One reason is that your body only needs a small amount of vitamin B12 everyday, so you can inhale it in 10-20 puffs. That’s not true with a lot of other vitamins, like vitamin C, which would take thousands of puffs. Another reason is that vitamin B12 is NOT sensitive to the heat associated with vaporising.

Ultimately, the existing data speaks for itself when it comes to the efficacy of B12 inhalation. It is many times more efficient than pill absorption, and comparable only to injections (though injections are still the most efficient).

Several of our customers that suffer from B12 deficiencies have measured their B12 levels by taking their regular blood tests and noted the rise in B12. Not only this, customers have been able to substitute their monthly B12 shot for our B12 inhalers; which have proven effective at keeping their B12 deficiency symptoms at bay.

Each Inhale Vitamin inhaler has the equivalent 1mg of Vitamin B12. 

But is inhalation 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.”

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

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 inhaled. The reason for this is the RDI (recommended daily intake) of these other vitamins is so high that you wouldn't received an adequate dose of each vitamin. However, vitamin B12 and B6 are ideal candidates for inhaling as the RDI is much smaller, the compound itself is small enough to be absorbed directly into the bloodstream via the lungs, vitamin B12 is not heat sensitive; the inhalation science goes back half a century.

How to verify how well Inhale Vitamins work for you?

In order to verify its effectiveness for yourself, you can follow some simple steps below:

  1. Consult your Doctor. Buy vitamin B12 blood tests at your local pharmacy or online.
  2. Go without B12 supplementation for 1 week (get your Doctor’s permission first) to establish your baseline B12 levels.
  3. Get your first B12 blood test performed.
  4. Inhale 10 breaths.
  5. Wait 5 minutes.
  6. Get your second B12 blood test performed.
  7. Repeat 4-6 for as many days as you’d like.
  8. Plot the results on a chart and see how well it worked for you!
