What’s the Best CBD Oil Strength?

Are you looking to purchase CBD oil but do not know what potency is the best? Herein, you will know the various CBD oil strengths, common potencies of CBD oil, and how to calculate CBD oil potency.  

CBD (cannabidiol) is a cannabinoid of the cannabis plant. The cannabis plant is divided into marijuana and hemp plant. The reason why CBD is extracted from the marijuana plant is that it contains low levels of THC. THC (tetrahydrocannabinol) is also a compound found in the cannabis plant. It is responsible for the high effect that one gets to experience after smoking marijuana. Unlike THC, CBD is becoming popular since it has calming and relaxing effects. There are various CBD oil potencies in the market; hence you can get confused on picking the right potency for your body. It is important to know the right strength that your body can tolerate to avoid any negative reactions that may occur.

The Problem with Buying CBD

Many CBD oil brands manufacture products that have different potencies. When going to the store, you will find many CBD sizes ranging from 300mg to 400mg milligrams. Due to the different options available, you might find it confusing picking a product, since you are unaware of the strengths. CBD’s potency is affected by various factors. Some of these factors include your health condition, CBD concentration, and whether the oil has other cannabinoids. White et al. (2019)  suggested that the FDA has not yet approved CBD products. It is also important to consult with your doctor since your doctor will help you know the right CBD potency for your body.

Common Potencies of CBD Oil

CBD potency refers to how strong CBD oil is. If the CBD extract is 400 milligrams, its potency is half of a CBD extract. Strengths also depend on the bottle’s size. The amount of CBD listed in milligrams is the dose found in the whole bottle. If the bottle is small, it means that it’s much stronger.

This means that 400 milligrams in a 20 milligrams bottle are twice as strong as 400 milligrams of oil in a 40 milligrams bottle. Keep reading this article to have a clear understanding of CBD strength.

Various CBD Potencies

Urasaki et al. (2020) stated that there are various potencies that you will come across in stores. However, you will get to choose from two or three options. If you need CBD oil as a supplement, you do not require a high amount of CBD oil to treat mild conditions. Many CBD companies produce CBD oils, which have the following potencies: 300 milligrams, 600 milligrams, and 1000 milligrams.

These potencies can be found in bottles of fifteen, thirty, or even sixty milligrams. However, you can also come across more potent CBD oils in 2000 milligrams and even 4000 milligrams.

Getting Started with CBD Oil

If you are a newbie, you should start slowly and consume CBD oil with low strengths. Since everyone’s body chemistry varies, what might work for you will not for another and vice versa. It is important to begin with a low amount to see your body’s reaction. Moreover, you should know which amount of oil will provide you with your desired relief.

How to Calculate the Potency of CBD Oil

When buying CBD oil, you should be aware that the size of the bottle is important. This can be explained by a case where there are 300 milligrams of CBD oil in a fifteen milligrams bottle, while another thirty milligrams bottle contains the same three hundred milligrams of CBD oil. So, which one is more potent? The entire CBD is spread equally to the total bottle contents. It means that a large CBD oil bottle is half strong as a smaller CBD oil bottle.

Below is how you can calculate the CBD strength in a bottle:

(The amount of CBD in milligrams)/ (the bottle size in milligrams) = the strength in milligrams or milliliter

With that being said:

  • Any amount below five mg/ml has slow strength since it is only 10% strong.
  • Any amount between fifteen and thirty mg/ml has medium strength since it is between 15%- 30 %
  • Any amount between thirty and sixty has high strength, meaning it is 30%-60% strong
  • An amount that is more than 60% strong is referred to as a concentrate since it has ultra-high strength

Low CBD Oil Strength

Most low CBD oil is available in a strength of 3000 mg and is found in 30 ml bottles. This means that its potency is 10%. For most users, this oil is strong enough to support their ECS. McFadden et al. (2021) commented that CBD oil provides benefits to symptoms such as:

  • Mild to moderate anxiety.
  • Body pains.
  • Mild headaches.
  • Insomnia.
  • Mild stress.

The low potency CBD oil is a good option for those who want to add it to their regular supplements.

Medium CBD Oil Strength (15-30% CBD)

This potency is a good choice if you want to increase your CBD intake. In case the low-dose CBD does not benefit you, you can try using this type of potency. It can be used to treat symptoms such as:

  • Chronic inflammation.
  • Moderate headaches.
  • Digestive issues.
  • Moderate anxiety.

High Strength CBD Oil (30-60 Percent CBD)

Everyone cannot tolerate this type of potency. It is used to treat specific conditions which require high-strength CBD oil. They include:

  • Epilepsy.
  • Severe insomnia.
  • Cancer.
  • Frequent headaches.
  • Multiple sclerosis.

The Best CBD Oil Potency

Smart et al. (2017) explained that there is no definite amount of the best CBD oil potency that you can consume. Therefore, find the best CBD oil potency for you; it depends on your condition. Since different CBD oil strengths treat different conditions, you cannot consume CBD oil with low strength if you have serious medical conditions. The person needs a high CBD oil potency to feel well. 


Choosing the right CBD oil strength for your body depends on the condition that you are facing. That is why there is no answer for the best CBD oil strength. By giving you the tips on different CBD oil strengths, we hope you will get to choose the right CBD oil for your body. You can also calculate its strength using the trick that we provided above. Always consult your doctor since your doctor will help you decide the right strength of CBD oil that your body can tolerate. Make sure not to consume CBD oil with low or high potency for your body.
