CBD Oil Strength: Your Complete Guide

Whether you’re new to taking CBD oil or a seasoned user, it’s important to understand the different CBD oil strengths if you want to ensure you get the desired benefits. But with so many CBD oil strengths available, how do you know which strength of CBD oil is right for you?! 

Lucky for you, we’ve put together a comprehensive guide on CBD oil strengths to help. So let’s explore the different potencies of CBD oil and how to work out what strength CBD oil you should use. 

What is CBD Oil and How Does it Work?

CBD oil, also known as cannabidiol oil, is a natural product derived from the hemp plant. Not to be confused with cannabis, CBD products are legal in the UK as long as they contain less than 0.2% THC. This is the compound found in cannabis that gets you high. Instead, CBD in the UK is commonly used for health benefits, including managing anxietypain relief, and improving sleep quality

CBD oil works by interacting with the body’s endocannabinoid system, which plays a role in regulating various physiological processes

What Does CBD Strength Really Mean?

If you’ve been looking into CBD products already, you have probably come across terms like “CBD strength” or “CBD potency.” But what does CBD strength really mean? CBD strength refers to the concentration of CBD in a product. This is typically in milligrams (mg).

The labelled CBD oil strength is distributed equally throughout the bottles of CBD oil, rather than CBD gummies or other edibles, which are labelled individually. So the amount of CBD in your CBD oil dosage will be much less than the amount indicated on the product.

How to Calculate the Strength of CBD Oil

To calculate the strength of CBD oil per drop, you can use this formula:

600 mg CBD / 15 ml CBD Oil = 40 mg of CBD per ml

CBD strength / size of CBD bottle = amount of CBD per 1 ml

40 mg CBD x 0.05 ml = 2 mg of CBD per drop

CBD per 1 ml x ml per drop = amount of CBD per drop

The Different Strengths of CBD Oil

The majority of CBD oils in the UK range from 250mg to 3000mg. We’ll break them down below to explain the ranges for each and who they are best suited for.

Low Strength CBD Oil

Low-strength CBD oil typically contains 250mg – 500mg of CBD per bottle. This is often recommended for beginners, however, there are other factors you need to consider when deciding what CBD oil drops you need, such as your weight, age and metabolism.

Medium Strength CBD Oil

Medium-strength CBD oil typically contains 500mg- 1000mg of CBD per bottle. This tends to be the best CBD dosage for CBD beginners as it offers a balance between potency and effectiveness. It’s also easy to vary your dose to try a higher strength if needed before investing in a strong CBD oil.

High Strength CBD Oil

High-strength CBD oil typically contains over 1000mg of CBD per bottle. This can range all the way up to 5000mg or even higher in some instances, although the average CBD oil range tends to stop at 3000mg. It’s best suited for those seasoned with CBD, with a higher weight range or other factors outlined below.

What Strength CBD Oil Should I Use?

When determining the strength of CBD oil to use, there are several factors to consider:

Body Weight

Your body weight can play a role in how CBD is processed by your body. In a study from 2011, it was found that individuals who weighed less than 50kg (7.8 stone) found a low-strength CBD oil suitable for their needs. Whereas participants over 100kg (15.7 stone) found they needed a high-strength CBD oil for similar results.

This indicates a higher body weight may require a higher strength CBD oil to feel the effects of CBD.


You should start to feel the effects of taking CBD oil after your metabolism has broken it down, typically 15 minutes after you have taken it. As metabolism slows down with age, it’s believed that the older you are, the more likely you are to need a higher-strength CBD oil for the same benefits someone younger than you might experience with a lower-strength CBD oil.

Desired Effects

The desired effects of CBD oil can also influence the strength needed. Higher potency oils may be more suitable for individuals seeking stronger pain relief while lower potency CBD oil may be sufficient for those looking for mild stress or anxiety relief.

Finding the Best CBD Oil Strength

When it comes to choosing the right strength of CBD oil, it’s important to start with low strength and gradually increase your dosage as needed. Here’s the best way to do this:

Start with a Low Strength CBD Oil

We recommend starting with a low-strength CBD oil, especially if you’re new to CBD. This allows your body to adjust to the effects and helps you determine your tolerance level.

Adjust Your Dose Based on Personal Response

After starting with low-strength CBD oil, pay attention to how you feel and adjust the dosage accordingly. It’s important to find the minimum effective dose that works for you in case you need a higher dose later. Remember, everyone’s response to CBD is different, so it may take some experimentation to find the right strength for you.

CBD Oil Strengths: Final Thoughts

Whether you are using CBD for pain relief, anxiety, or sleep, choosing the appropriate CBD oil strength will ensure you have the best results from taking CBD. Most CBD users will find a happy middle ground with a medium-strength CBD oil, but determining the right CBD strength for yourself depends on various factors like your body weight, tolerance, desired effects, and the severity of the condition you’re addressing.
