What is the correct dosage of CBD?
Cannabidiol (CBD) is available in many forms, including oils, tablets, and creams. The ideal dosages vary depending on both its form and usage. There is little research, though, so doctors are not yet able to confirm the safe, beneficial dosages for each use.
CBD is an active ingredient in the cannabis plant. Products that contain CBD may provide some health benefits, but they can also pose risks.
The CBD market is growing at a fast rate, and the body of research is expanding. However, there is still confusion about the laws, how to use CBD, and its safety and effectiveness.
CBD products are legal, though their legal status varies among states. The Food and Drug Administration (FDA) do not control most CBD products. As a result, the quality, amount of CBD per dose, and safety of the products can vary dramatically, and it is difficult to calculate an optimal dosage.
This article looks at the dosages of CBD, including the research into which dosages are safe and effective, as well as the possible risks of using CBD products.
Before using any other CBD products, a person should speak to their doctor about appropriate dosages.
The dosage that a person takes will depend on the method of administration that they are using and the specific product. Methods of administration include:
- CBD oil solutions
- CBD capsules
- tablets that a person places under the tongue (sublingual)
- nasal sprays
Recently, a wider range of products containing CBD has become available. These items include food products, dietary supplements, cosmetics, and animal health products.
Research into CBD therapy is still in its early days, and scientists need to conduct many more research studies to determine the benefits and risks of CBD products. Importantly, researchers need to work out the ideal CBD dosages that are both safe and effective for each condition.
As a therapy, CBD oil has gained a high level of research interest. At Medical News Today, we have covered what the research to date has shown about the role of CBD in the following conditions:
- weight loss
- attention deficit hyperactivity disorder (ADHD)
According to a World Health Organization (WHO) report, research has suggested that CBD oil may also have therapeutic benefits for the following conditions:
As the FDA have only approved the use of CBD for specific forms of epilepsy, doctors know little about what dosage people should take when they use it for other reasons. As with any drug, the appropriate dosage is one that provides a therapeutic effect and is well-tolerated.
In clinical studies, researchers have used various oral dosages of CBD, ranging from 100–800 mg per day.
Some studies use even higher dosages. According to a review, an individual reported an improvement in psychosis after taking 1,200 mg per day for a few weeks. In another study, people with schizophrenia reported benefits after taking increasing dosages of 40–1,280 mg per day for 4 weeks.
In a study into the effects of CBD in people with Parkinson’s disease and psychosis, six participants showed significant improvement in symptoms with a dosage of 150 mg per day of CBD.
The following table lists the method of administration and dosage of CBD that researchers have used to study its therapeutic effects on different medical conditions.
|Medical condition||Dose of CBD||Form|
|bowel disease||5 mg twice daily||sublingual|
|type 2 diabetes||100 mg twice daily||oral|
|pain due to cancer||50–600 mg per day||oral|
|Parkinson’s disease||75–300 mg per day||oral|
|Huntington’s disease||Up to 12 sprays per day||Sativex nasal spray (contains CBD and THC in 1:1 concentration)|
To find out whether a CBD product is safe and to determine the effective dosage, people should consult a doctor.
