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 the 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 CBD dosage and gradually increase your CBD dosage. 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 millilitres (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.
A 2011 review of trusted Source on the safety and side effects of CBD found that continuous use of CBD, even in high doses like 1,500 mg a day, is tolerated well by humans.
A 2017 update of trusted source 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 diarrhoea, 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 labelling.
A 2018 report from the Centers for Disease Control and Prevention (CDC)Trusted Source 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.
