What Is the Difference in CBD Oil Strengths?

When you are shopping for CBD, the first thing that you will notice is that CBD oil strengths vary. If it is your first time buying, it can be overwhelming to figure out the potency that best suits your needs. 

This guide will help explain what each strength of CBD oil stands for and how you should choose a CBD tincture of a specific strength range, and it will provide some tips on finding the right product for you!

CBD Oil Strength

CBD strength/potency refers to how strong your CBD product is regarding its effects. If your CBD is rated 150 mg, it will be half as potent (strong) as the same tincture rated at 300 mg CBD. 

However, there is more to potency as it can rely on the actual quantity of CBD in a bottle. The total amount of mg CBD listed refers to the dose in the entire bottle. The potency should be high if your CBD is in a small bottle.

For instance, 150 mg in a 20 mL bottle should be twice potent as 150 mg CBD oil in a 40 mL bottle. Don’t get confused; we will make it all clear. Keep reading!

How Do I Choose CBD Oil Strength?

Choosing the right strength of your CBD product is essential as finding the best CBD oil for you. Like most things, choosing the one that’s right for you is to consider your personal needs and preferences.

The most common question we get from customers is, “how much mg of cbd is in my cbd oil?” CBD percentage to mg (or “mg/ml”) is one of the easiest ways to determine how much CBD is in a product  (1ml = 1000mg). The higher the percentage, the more milligrams of CBD you can find in each serving size. 

Below is how you can calculate the CBD potency before choosing a product 


  • Low-strength products often have around 5-15% i.e.  5 mg/mL will be (10%)
  • Mid-range strength are 15-30%, i.e 15 and 30 mg/mL
  • CBD high-strength products typically contain 30-60%. Ie 30 mg/mL to 60mg/mL

This can provide some guidance as far as quantity go. Concentrates are considered ultra-potent as they range higher than 60%; however, not everyone will need or want precisely those amounts of CBD in their bodies at once.

CBD Percentage to Mg

One of the most important things to know about CBD is how much CBD it contains. If a bottle’s label says 100 mg of CBD, that means there are 100 milligrams of Cannabidiol in each ounce (or 30 mL) of oil. 

It is common to see a potency value in milligrams (mg). Therefore, if you are looking at an item with 20 mg/ml, that means there are 20 milligrams per milliliter—or 0.05% strength!

Low Strength CBD Oil (10% or less)

 Low strength CBD comes in 300 mg of a 30 mL bottle (10%). Low-strength cbd oils are usually good for beginners or people who want to try it out without getting too much of a hit from the active ingredient. These oils have lower levels of CBD but just enough to affect your body. 

Mid-Range Strength CBD Oil (15-30%)

At the mid-range level, more than 300 mg (30ml) is a good amount for most people. The dose is ideal for anyone taking low potency CBD but wants effects that are more potent.

High-Strength CBD Oil (30-60%)

High-strength CBD oil is for those who want a highly potent dose of CBD. It comes in various forms, but the most common is an oral tincture that can be taken sublingually. You can also use high-strength CBD oil topically for your skin.

If you’re looking for something more potent than 1500 mg of CBD per bottle, we recommend trying high strength CBD products.

Which CBD Oil Is Right for Me

The right strength of Cannabidiol depends on your body and the effects you are seeking. As a rule, the lower the mg number on a bottle of CBD, the higher its potency will be. 

We recommend starting with a lower dose and working your way up until you reach the desired results to find the correct strength.

Wrap Up on Different CBD Potencies

Choosing the right product can become challenging with the significant number of CBD products and different potencies/strengths available. There is a lot of information about CBD dosing, but if it is not broken down, you may not understand it.

We hope this guide on CBD potency helps you understand the difference between different strengths before you buy CBD online so that you can make an informed decision about which one works best for what purpose(s).
