CBD and Bioavailability Issues
The rise in CBD sales across the US has been nothing short of astonishing in the past few years. With dispensaries along with CBD products popping up in seemingly every town like wildfire, it may seem at first that CBD is a panacea. A product that has few, if any downsides while treating a wide variety of conditions.
However, CBD is not perfect, and it does suffer from the same thing that affects the intake of vitamins and minerals. The bioavailability of the CBD is quite small which means that getting the full effect is often not possible when taking the product in the recommended manner.
What is Bioavailability?
Bioavailability means how much of the product is absorbed into the bloodstream after ingestion. For CBD, the bioavailability rate is somewhere around 15% when swallowed. This means if you take a 20mg capsule of CBD, you can expect about 3mg to actually be absorbed into the bloodstream while the rest is either broken down or passed through the digestive system.
This is why many CBD products that are designed to be consumed are recommended to do so with a meal. That’s because adding food actually increases the bioavailability of CBD, vitamins, and minerals into the bloodstream. The liver which metabolizes the CBD means that products such as soft gels, drinks, capsules, and gummies are mostly broken down and dissolved before they reach the bloodstream.
Methods of Absorption
The digestive system is only one way that the CBD can be absorbed, there are other methods as well which include the following;
- Time-released capsules
Tinctures are CBD that is placed below the tongue, allowing for a more direct absorption. The rate is about 25%, give or take 5%. It is recommended that you keep the CBD under the tongue for at least 20 seconds for better absorption.
Balms and skin creams have less bioavailability compared to swallowing the product and are best suited for treating conditions such as muscle soreness topically. Time-released capsules bypass the stomach and open in the intestinal tract which also improves CBD bioavailability, although the increase is not much.
The vapor goes into the lungs and also bypasses the liver, meaning the bioavailability is even higher. However, there have been recent reports of issues with vaporizers, particularly those that carry CBD which must be fully studied.
Nano-CBD May Be the Solution
One promising aspect is the development of nano CBD. This is an enhancement or concentration of CBD that is easier to get into the bloodstream when swallowed. Nano CBD is created in a similar fashion to standard CBD but is concentrated so that more is absorbed into the body.
The impact of nano CBD is faster, and it contains the same elements as standard CBD products. For those who are having difficulty with the bioavailability of regular CBD, the nano version appears to be the right solution. Because it is a concentrate with no additional products added, it is legal in all states that approve of standard CBD. It may be the solution you are looking for in terms of better bioavailability.
