CBD has been embraced by the health and wellness community due to the ever-growing body of research that suggests that it can be effective in treating physical and medical disorders.
In the UK, shops now provide CBD in various different forms including pills, capsules and even suppositories. This can make it difficult for consumers to choose the right method for them.
Bioavailability – why it matters
It is important to take bioavailability into account when deciding on your CBD purchase.
Bioavailability sounds complicated but all it refers to is the degree that a substance is absorbed into the bloodstream. This is important because the body can only use what is absorbed.
Injecting directly into the bloodstream has 100% bioavailability however this should only be carried out by a doctor.
Luckily there are other methods to choose from; each with their own bioavailability rates. For example, if you took 100mg of CBD but ingested only 20mg the bioavailability would be 20%.
Oral is the most popular way to take CBD. Most health and wellness shops provide capsules and pills even CBD gummies now. This is recommended for those new to CBD as this method is non-invasive and non-itimidating.
Despite its popularity, oral consumption is in fact not the most effective option.
In 2009, a team of researchers discovered that one could optimistically expect a bioavailability of 20% when consuming CBD orally. This means you’ll be losing out on 80% of the CBD you purchased! This is a result of your digestive system breaking down everything in your stomach before it is absorbed by your intestines into your bloodstream.
Further to this, oral is one of the slowest methods and can between 30 – 120 mins depending on how full your stomach is.
Vaping increases to grow in popularity every year. In the UK, companies such as dank! Vapes provide CBD E Liquid that can be used in any vaping device. When using a vape pen or a mod tank, a user will inhale CBD directly into the lungs.
The respiratory system is one of the most effective ways to ingest compounds. This is because the lungs offer almost instant access to the bloodstream. There have been multiple studies carried out by doctors that suggest the bioavailability rate of the respiratory system is over 50%. By far, vaping is one of the most effective ways to get CBD into your body.
Sublingual simply means ‘under the tongue’. Using tinctures to place a few drops under the tongue are a popular way to ingest sublingually.
When you place a few drops under your tongue your saliva will begin to dissolve it and then absorb it directly into the bloodstream. You’ll feel the effects of sublingual consumption far faster than oral because with this method you bypass your digestive system.
You should feel the CBD begin to take effect within minutes and last for at least a few hours. Sublingual consumption is fairly effective with a bioavailability of 35%.
