What is CBD bioavailability and Why does it matter?

Bioavailability of CBD oil

When it comes to CBD, it is important to understand what bioavailability is, which is the factor that determines exactly how CBD is absorbed by the body. Understanding it can be very useful in choosing the right CBD product for you that will help you boost your mood and sleep, help you manage chronic pain, or just give you overall relaxation without causing adverse effects. This article will provide you with more information about bioavailability to help you get the potential effects of CBD based on your needs and how you choose to take it. 

What is CBD Bioavailability?

Bioavailability refers to the ability of a drug or substance to be absorbed and used by the body. More accurately, it refers to the degree and rate of the initial oral dose of a drug until it reaches the bloodstream. For CBD, its effectiveness is determined by how it reaches and interacts with the endocannabinoid system (ECS) which is a biological system that helps regulate and balance functions in the body.

When choosing CBD products, you might want to keep bioavailability in mind as it influences the distribution of the compound throughout your body. The absorption rate and potency of CBD depend on our weight, height, body mass, and individual biochemistry. This means that the higher the bioavailability is, the easier it will enter the bloodstream. This is important for consumers for them to know which CBD products will suit them best. 

Why is bioavailability so important?

CBD bioavailability is important for CBD users as it could help avoid situations where someone might not feel any effects after taking it. It can also increase the chances that CBD will deliver its full health benefits even though the effects of CBD vary from person to person. Also, bioavailability is important when choosing CBD products to help us determine the form of CBD that we should use as well as the amount that we need to take to receive the optimal dosage in our system. Knowing the right form of CBD will help decrease the amount of CBD lost due to natural processes in the body, making the consumption less wasteful and costly. 

Which type of CBD has the highest bioavailability?

The delivery method also has a lot to do with how much CBD enters the bloodstream. Products with absolute bioavailability can be used less and still achieve significant benefits. But for CBD products with lower bioavailability, you may need to use a more significant amount to enjoy the same relief. Below is a quick guide to help you understand the bioavailability of different CBD products. 

Topical CBD

CBD topicals such as creams or lotions are meant to be directly applied to the skin with soreness and pain. The potential effects of CBD topicals can be felt within 15 to 3 minutes after application. However, since CBD topicals are not ingested, they won’t pass through the digestive tract. CBD topicals have a low bioavailability of 1-5% since they are not permeable enough and won’t ever reach the bloodstream. However, CBD topicals still provide great benefits such as soothing skin conditions such as acne and eczema. 

If you want to try a good CBD topical product, try CBD Shopy’s CBD Muscle Rub (1000mg).

CBD capsules

Oral CBD formulations such as CBD capsules have a poor bioavailability of 4-20%. Consuming CBD capsules will take about 30 to 40 minutes after oral administration to be absorbed by the body as it needs to pass through your digestive tract and then to your bloodstream. The potential effects of CBD capsules can last for about 2 to 6 hours and will provide you with longer CBD effects.

If you want to try a good CBD capsule product, try CBD Shopy’s Full Spectrum CBD Capsules (1500mg).  


CBD oils are usually taken using a dropper, tincture, or oral sprays. This method of consumption is one of the most effective and simple ways to get a high bioavailability absorption rate and is believed to have an oral bioavailability of 35% as it is directly absorbed by the blood vessels and not through the digestive tract before getting absorbed by the bloodstream.

One of the best CBD oil products on CBD Shopy that you can try is the Full Spectrum CBD Oil (1000mg).

CBD gummies

Ingesting CBD edibles such as CBD gummies are the most popular way to consume CBD. They are discreet and the easiest way to take CBD without having to taste the earthy taste of hemp. Similar to taking CBD capsules, CBD gummies also have the lowest bioavailability of 4-20% as they need to pass through your digestive tract before going to the bloodstream. But even though CBD gummies have lower bioavailability, people like taking them as they still provide therapeutic effects and don’t taste any different from taking regular gummies.

If you want to try the best CBD gummies product on CBD Shopy, you can try the Zenbears CBD Gummies (600mg).
