Mislabeling appears to be a fairly common problem with CBD products. In one study, 70% of the CBD products that were sold online contained significantly more of the psychoactive ingredient THC than the label indicated.
So what is the maximum amount of CBD you should take? Researchers have found that 600 mg per day appears to be safe, but one study suggested that doses of up to 1,500 mg a day are safe and tolerated well.

Before you try CBD, discuss your plan with your doctor. They may be able to recommend a dose and help you better understand any potential risks, complications, side effects, or interactions you might experience.
CBD is believed to have a range of positive physical and mental health effects. Because of this, it has become increasingly popular as a way to alleviate everything from anxiety to sleep disorders.
In studies, amounts vary from as low as 20 milligrams per day to up to 1,500 milligrams (mg) per day. The World Health Organization reports that dosages in clinical research studies typically range between 100 and 800 milligrams per day.
The amount of CBD found in a product may depend on different factors, including the formulation and method of administration. CBD products are available in a number of different forms including oils, capsules, tablets, nasal sprays, and gummies.
Is It Possible to Take Too Much?
One report by the Centers for Disease Control and Prevention (CDC) indicated that a number of people experienced negative unwanted side effects due to CBD products that contained synthetic CBD, although the products were not labeled as containing such ingredients.
One of the most popular ways to take CBD is as an oil. Such products are made by combining CBD with some type of carrier oil, such as coconut oil. Some more recently developed products include dietary supplements, foods, beverages, lotions, salves, and cosmetics.
CBD oil comes in different forms. Isolates contain only CBD, but full-spectrum oils have several compounds from the cannabis plant. This includes proteins, flavonoids, terpenes, and chlorophyll.
There are also CBD capsules, CBD gummies, and under-the-tongue CBD sprays.
CBD is the short name for cannabidiol , one of the two chemicals in cannabis with the most health benefits. The other chemical is tetrahydrocannabinol (THC).
However, CBD oil might change the way your body breaks down certain medications. This could make the drugs have a stronger or weaker effect, which can be dangerous. Talk to your doctor before you use CBD oil, especially if you take any medicine or have liver disease.
What to Look For
Epidiolex is used to treat two rare forms of epilepsy in children under 2: Dravet syndrome and Lennox-Gastaut syndrome. These are very rare genetic disorders that cause lifelong seizures that start in the first year of life.
Common side effects include:
Alternative medicine practitioners believe these compounds provide more important health benefits, but there's no clear evidence to support this.
What Is CBD Oil Used For?
However, there’s no evidence CBD oil can treat high blood pressure on its own or prevent it in people at risk. While stress can complicate high blood pressure, it can’t cause it.
Scientists believe CBD reduces nerve pain by binding to receptors in the brain that control the speed at which nerve signals pass between nerve cells.
