How To Increase Sublingual Absorption

If you’re taking sublingual CBD or supplements, it’s probably because you want to be sure your body is getting the most out of them, right? So, the big question is, how do you maximize sublingual absorption?
By Brooke Mangum

If you’re taking CBD or supplements under your tongue, you’re probably concerned with absorption. You want to make sure that your body is utilizing everything you give it. 

I’m sure you know, but in case you don’t, sublingually is the most effective way to absorb CBD, supplements, and many medications. But if you’re anything like me, I bet you’re thinking “what can I do to get the absolute best ‘bang for my buck’ from CBD,” right? 

There’s both good news and bad news. The bad news is that sublingual absorption is already pretty perfect. The good news is that you aren’t out of options to supply your body with more CBD than it’s currently getting.

Sublingual Absorption and Bioavailability: A little dab’ll do ya…

Sublingual absorption just means “under the tongue”, whether you’re talking about  a medicine, supplement, or CBD. Instead of swallowing the CBD, the particles have been broken down into smaller pieces and emulsified into a special water based liquid that lets them pass through the glands under your tongue. 

These glands allow CBD to slip right into the bloodstream instead of having to digest it first. This allows more of the CBD to be absorbed by the body. 

This way, there’s no loss of potency or damage to the CBD from being digested and filtered by the liver. Your endocannabinoid system gets almost 100% of the amount you take, as opposed to less than 10% with some other methods..


Normal CBD is good for you, but you sometimes have to take A LOT because your body wastes so much. That’s called “poor bioavailability.” 

Anything you ingest by swallowing has to go through your digestive system first. Your stomach acids break down and spin it like a washing machine to help you start absorbing it. Then, the content drains into your intestines to be further broken apart and stripped for parts… Nutrients and active compounds like CBD are processed by your body, especially your liver, and what remains of them are sent to your bloodstream. 

This is called the first pass effect, and it changes the strength of a lot of drugs, vitamins, and supplements.

Some vitamins and nutrients do really well with first-pass metabolism.. CBD ain’t one of ‘em.. 

CBD particles are large, and they take quite a beating from your intestines and your liver before they ever reach your endocannabinoid system. 

So, you may believe that you have swallowed 60 mg of CBD. But, by the time it reaches your endocannabinoid system, you will have a lot less than 60 usable mg of CBD actually being used.

CBD also happens to be fat soluble. That means that your body cannot use CBD until it has been dissolved into a fatty substance. Your body actually uses the CBD-infused fat, rather than the CBD itself. This can be avoided with nano emulsified CBD, which is basically water-based, just like your body is.. 

Nano CBD

Nano CBD oil begins as regular CBD oil. Rather than bottling it up the way it came, CBD producers use a second process to make the particles smaller. There are two ways to make CBB particles smaller. 

The first, and the simplest, is something called ultrasonication. Ultrasonication uses tiny ultrasound waves that are powerful enough to break the particles down. This is exactly what electric essential oil diffusers do. If you like to make your home smell nice with an electric diffuser, you have an ultrasonication device in your house.

Microfluidization, the second method, is a little more complicated. Microfluidization requires the use of a special machine that forces CBD through a zig zag tube. This tube is designed to break the particles down, resulting in the uniformly sized tiny little bits of CBD. The end result is CBD particles that are much smaller and therefore much easier to use. 

But, in either process, you’re still only half done… See, these little particles like to clump back together to form back into BIG particles. It’s their natural state. So they need to be stabilized, to keep ‘em small.

That’s where the second part comes in. It’s called nano emulsification. This generally works the same across the board. The nano CBD particles are blended into a fatty substance, just like they would need to be inside of your body. Your body receives the CBD already infused into the fatty substance, and saves itself some work. 

These microparticles made of CBD and fatty acids are only a few nanometers wide. That’s MICROSCOPIC. Not only are these nanoparticles tiny, they don’t clump together anymore. That means these particles can be mixed with water (not something you can do with “regular oil”). 

That means that nano emulsified CBD can effectively be used sublingually. The tiny, water miscible particles simply pass right through the tissue underneath your tongue.


The process of taking nano CBD sublingually isn’t any different than taking regular CBD sublingually. It’s the effects that are different. 

Sublingual nano CBD works so quickly that you can take it when you need it. You don’t have to pre-emptively take it and hope it will kick in when you’re counting on it. Nano CBD is as close to instant as CBD gets. 

Nano CBD’s water miscibility and smaller particle size let it get to work very quickly, usually within 15 minutes or less. They have an express route to your endocannabinoid system, right under your tongue. Larger particles of CBD can take up to 4 hours to fully take effect when swallowed. Your body needs to digest and prepare the CBD.  There’s a pretty stark difference between 15 minutes and 4 hours. 

If you’re taking your CBD to help you sleep, you don’t want to wait 4 hours to feel it. 

You want to be able to take it right before you tuck yourself in at night and be on your way to la la land…

Because nano CBD works so faster and more effectively, you don’t necessarily need to take a large dose. There is no waste with nano CBD. You’re going to get the amount of CBD that you took. 

Let me break it down this way: If you normally use 1,5000 milligrams of “regular” CBD, you can use a much smaller concentration of nano CBD to experience the same effect. 

What’s the Best Way to Maximize CBD Absorption?

The best way to maximize CBD absorption is to take nano CBD sublingually. It’s the perfect combination of factors to promote absorption and bioavailability. No other method is capable of delivering CBD the same way. 

If you’re taking traditional CBD, the best way to promote absorption is to eat it with high fat foods since it’s fat-soluble. But, eating high fat foods with your CBD will also decrease its potency. It’s a double edged sword, and you still have no way of knowing how much CBD you’re actually getting and when you’re getting it. 

The Takeaway

Taking nano CBD sublingually is the best way to get the most out of every milligram of CBD you take. Nano CBD is designed to work with your body. It’s easy for your endocannabinoid system to use, and it starts working quickly. 

Whether you choose to take sublingual CBD or you prefer capsules, shots, or gummies, every product is giving you the maximum benefits. 

Just make sure you’re always choosing what’s best for you.
