You’ve probably heard about the health benefits of CBD, but how much should you take to feel those?
CBD isn’t psychoactive — meaning it won’t get you “high.” Instead, research suggests that it may help:
No matter what condition you’re trying to treat with CBD, giving yourself an adequate dosage is key — or it might not work for you.
Here’s what you need to know about figuring out how much CBD to take.
CBD has been the subject of a lot of discussion and research over the past few years.
As this 2017 review 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.
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.
One drop is about 0.05 milliliters (mL). That is, not a full dropper — just a single drop.
A 2017 update to this review also confirmed this. However, a 2019 study done on mice did raise some safety concerns about CBD’s potential for liver damage and its interactions with other medications.
If you’re currently taking medication and would like to try CBD, it’s essential to discuss this with your doctor.
There are very few known side effects of CBD. When side effects do occur, however, they may include diarrhea, appetite changes, and fatigue.
Possible side effects
- changes in appetite
- changes in weight
If you’re looking for a quick and easy way to buy CBD, you can find many CBD brands online. But make sure you research each brand before purchasing. While pure, genuine CBD is considered safe, fake and low-quality products can be dangerous.
CBD isn’t regulated by the FDA, so it’s up to you to make sure that you’re only using high-quality products. Look for products from a reputable brand with third-party testing, and avoid companies that have a history of inaccurate labeling.
A 2018 report from the Centers for Disease Control and Prevention (CDC) noted that 52 Utah residents had bad reactions to certain CBD products. It turned out that most of them used products that included synthetic CBD. Some products contained no information about the manufacturer or its ingredients.
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.
Is CBD Legal? Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Check your state’s laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.
