If youāre reaching for cannabidiol (CBD) oil, odds are youāre looking for:
- pain relief
- better sleep
- relief from other symptoms while avoiding the intoxicating effects of cannabis or specific pharmaceutical medications
That being said, itās also nice to know that what youāre reaching for is strong enough to make a noticeable difference for your symptoms.
Keep reading to learn about the strongest CBD oils and how to safely use and shop for them.
Weāll also suggest a few of the best strong CBD oils.
Whatās considered āstrongā when it comes to CBD?
You can find CBD products ā whether broad-spectrum, full-spectrum, or CBD isolate ā in a number of different potencies. While thereās no one definition of āstrongā CBD, we consider high potency to be at least 50 milligrams (mg) of CBD per 1-milliliter (mL) serving.
However, keep in mind that CBD affects everyone differently, so what feels strong to you may not feel as potent to another person. Thatās especially true if youāre brand new to CBD.
How we chose the strongest CBD oils
Each product in this article contains at least 50 mg of CBD per mL of product.
There are lots of high-potency products out there, so we narrowed things down with criteria we think are good indicators of safety, quality, and transparency.

- is made by a company that provides proof of third-party testing by an ISO 17025-compliant lab

Food and Drug Administration (FDA) warning letter - whether the company makes any unsupported health claims

How to shop for CBD
For now, the FDA doesnāt guarantee the safety, effectiveness, or quality of over-the-counter CBD products.
You can avoid purchasing CBD products that are misrepresented or mislabeled by looking for products that come with an up-to-date COA from a reputable third-party lab.
Once you have the COA, review it to make sure the amount of CBD and THC thatās in the product matches whatās advertised.
Contaminant testing results are another important area to review. These vary by brand, but in general, itās good practice to keep an eye out for testing results for pesticides, heavy metals, and molds.
Itās also always a good idea to make sure youāre buying from a company thatās transparent about where they grow their hemp and how they produce their products.
This information should be readily available on the brandās website so you can review before buying.
How to use CBD oil
CBD oils can be used by placing them under your tongue using a dropper (most CBD oils come with one) or by mixing them into drinks and food.
Shake the bottle before dropping the dose under your tongue. If youāre looking for maximum absorption, keep it under your tongue for 30 seconds to a few minutes before swallowing.
To store, safely secure the cap on your CBD oil and keep it in a dry, cool place. You can also stick it in the refrigerator to extend its shelf life.
CBD dosage
To learn how many drops to use, follow the recommended dose provided by the manufacturer or your doctor.
Proper serving sizes for CBD vary widely depending on individual factors, like:
- intended use
- body weight
- metabolism
- body chemistry
The four factors listed above should be considered on a case-by-case basis as CBD can work differently on individuals.
Itās always best to start with a small dose so that, if needed, you can increase it over time until you reach your preferred results.
Doses should be spaced at least 4 to 6 hours apart but can be taken at any time of day. Of course, if youāre looking to improve sleep, take it before bed.
The immediate effects of CBD typically happen within 30 to 90 minutes. Depending on your preferred method of administration, the immediate effects may vary.
Long-term results may take a number of weeks to accomplish.
Safety and side effects
Though research suggests CBD is pretty safe to use, some people experience side effects. These include:
- fatigue
- diarrhea
- changes in appetite
- changes in weight
If you decide to mix CBD oil into drinks and food, this may affect absorption. If you take it with a high fat meal,
Itās a good idea to avoid touching the dropper to your mouth to prevent bacterial contamination and to safeguard the quality of the oil.
If you take any medications or supplements, talk with your doctor before trying CBD.
