CBD has been the subject of a lot of discussion and research over the past few years.
As this 2017 review Trusted Source shows, a great deal of research has found that it’s a relatively safe treatment. The studies analyzed in that review didn’t show that there’s one universal dosage of CBD that everyone should take. Instead, it underscored the fact that different people (and, in the animal studies, different animals) respond to different dosages of CBD. Most of the human studies use dosages anywhere between 20 and 1,500 milligrams (mg) per day.
It’s worth remembering that there’s still a lot about CBD that we don’t know. As the cannabis industry grows, researchers will likely conduct more studies on cannabis, including marijuana and hemp, and its derivatives.
Figuring out the right amount for you
The amount of CBD you should take depends on a range of factors, including:
your body weight
the condition you’re treating
your individual body chemistry
the concentration of CBD in each pill, capsule, drop, or gummy
In other words, there are a lot of variables that go into deciding how much CBD to take. Before trying CBD, be sure to talk to your doctor about an appropriate dosage and any potential risks. If your doctor tells you how much to use, stick to their recommendation. This is especially important if you’re taking a prescription medication that contains CBD, such as Epidiolex, a form of seizure medication.
If your doctor doesn’t provide a recommendation, it’s best to start with a smaller dosage and gradually increase it. This could mean starting with 20 to 40 mg a day. After a week, increase this amount by 5 mg. Continue this until you feel that it’s effectively treating your symptoms.
For example, you might start off with 40 mg to treat severe pain. You can take 40 mg on days when you’re in a lot of pain. After a week, you increase it to 45 mg, and after a second week, you use 50 mg. At this point, you might feel that your pain is bearable.
It might be wise to keep track of how much CBD you’re taking and whether your symptoms are getting better. Write it down on paper or in a notes app on your phone.
Start with a small dosage of CBD and increase slowly until you reach your desired effect. Your ideal dosage of CBD depends on a lot of factors, like your body weight, body chemistry, the condition you’re treating, and the concentration of CBD in the product you’re using.
How to calculate dosage
Some products, such as CBD gummies, capsules, or pills, tell you how much is in a single serving. For example, the packaging on a bottle of CBD capsules might indicate that there are 5 mg of CBD per capsule.
If you’re using CBD oil, it’ll likely come in a dropper bottle. The packaging might specify how much CBD is in a single drop. From there, you can figure out how many drops you need to use.
Sometimes it’s harder to figure out how much CBD is in one drop because the packaging specifies the total amount of CBD in the entire bottle, but not the amount that will be in a single drop.
One drop is about 0.05 milliliters (mL). That is, not a full dropper — just a single drop.
This means that a 10-mL bottle of CBD oil contains 200 drops. And if the packaging for that 10-mL bottle says that the bottle contains 1,000 mg of CBD, each drop will contain about 5 mg of CBD.
So, to have 20 mg of that type of CBD oil, you should take four drops.
When it comes to working out which dosage of CBD you should use, talking to your doctor is your best bet. While not all doctors will be able to provide information on CBD — depending on the laws in your state — some may be able to help recommend dosages or high-quality brands. Speak with your doctor before trying CBD, especially if you’re currently taking any medications.
