Hey Folks,

It’s Dr. Gerstmar from Aspire Natural Health, and in this quick video, I want to answer a patient question I heard last week.

And that is, what does the word sublingual mean. You may have heard that word too. Certain vitamins or preparations of medicines are supposed to be taken sublingually. But what does that mean, and why would you take something that way?

Okay, in order to make sense of all this we need to understand how things get into our bodies.

And in general there are three normal ways things get into our bodies.

The first, if they’re a gas or something we breathe in they can be absorbed by our lungs. And so some medicines like asthma medicines are going to be in a spray or an inhaler. Also things like essential oils can be diffused into the air and breathed in.

The second is that our skin can absorb things into our bodies, which is why it’s important to be aware of what we put onto our skin. Things like soaps, lotions, and other beauty products, cleaning products, and other things can all contain things that can be absorbed by our skins into our bodies. Which is why it’s important to use healthy skin products. One website that I recommend is called Skin Deep by the Environmental Working Group. If you do a quick search you’ll find it and they have some great resources there.

The third and most common way that we absorb something into our bodies is through our digestion. Whether it’s something that we drink or eat, it goes into our digestion and is absorbed into our bodies.

Now the important thing here is that once it’s inside our bodies it goes to the first checkpoint and that’s the liver. One of many jobs the liver has is to screen everything that comes into our body through our digestion and deal with any problematic things. This is a very good thing most of the time as it protects us from harmful things.

But it can be a bad thing if we’re taking medicine to help resolve an issue, and if right away a bunch of it that was absorbed from your digestion gets detoxified by the liver before really getting into your body and doing what it was designed to do.

Does that make sense?

So most medicines that we take we’re going to take as a pill, capsule, or liquid. They’ll go into our digestion and be absorbed there into our bodies, and for many medicines that works just fine.

However there are a few reasons we wouldn’t take something that way. The first is if our digestion is very poor. We’ve seen many people over the years with very poor digestion who have trouble taking things – whether they’re prescription drugs or herbs or vitamins – because their digestion is just really messed up.

The second reason is that some things are just not absorbed by the digestion. And the third is that the liver destroys a big chunk of it before it can get into the body and do its job.

So if we don’t want to take something the normal way through our digestion what can we do?

The first thing we can do is inject it. Whether it’s a shot, or an IV infusion we can bypass everything and just put it right into our bodies. And that can work really well for a variety of medicines or when the digestion is just really messed up. But most people don’t enjoy getting poked with needles.

The second way is we can breathe it in. There are certain medicines that can be nebulized and breathed in, but the majority of medicines can’t.

The third way is to put it on our skin. And there’s a whole bunch of different things that can be taken that way.

And lastly, there’s sublingually. Sub means below. Which is why it’s called a sub-marine. Marine means sea or ocean, so a sub-marine is a ship that is below the ocean.

Lingua means tongue. So sublingual means below the tongue. The reason is that beneath our tongues we have some major blood vessels that are very close to the surface of the skin, and it’s possible for things to absorb directly from the mouth into the blood stream without having to go through the rest of the digestion or the liver.

The most common supplement that is given sublingually is vitamin B12. And that’s because B12 is one of the most difficult vitamins to absorb. And if you have any issues going on with your digestion it can be even more difficult to absorb B12.

You can take B12 shots and they work incredibly well, but most people would prefer not to have to give themselves injections. So there are many formulas for sublingual B12 that you take under your tongue and held there while it dissolves to let as much as possible absorb directly into your bloodstream.

I do need to point out that there is debate about just how much B12 is absorbed by taking it sublingually. But in general for many people we’ve found a sublingual B12 can work very nicely to improve someone’s B12 status.

Alright, so there you have it…



I hope that’s helped you understand not just what sublingual means but the different ways that things get into our bodies. None is the right way. Some are going to work better for certain things than others, and taking things sublingually can work really well for some things.
