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.
Federal law prohibits the sale of products that contain more than 0.3% THC. States laws also vary, so you should always check with your state before buying CBD products online.

Looking at the dosage information for the CBD product that has been FDA approved can also be helpful. For Epidiolex, an FDA-approved cannabis-derived medication used to treat seizures in people with certain types of epilepsy, the starting dosage is 5 milligrams per kilogram of body weight. This dose can later be increased to 5 mg per kilogram of body weight twice a day.
Start With a Low Dose
It is important to remember that these benefits have not yet been conclusively proven. More research is needed to determine the role that CBD might play in the treatment of different disorders and health conditions.
Other CBD products are not FDA regulated and do not have officially recommended dosages. This can make it difficult to determine how much you might need, but there are some things you can consider that might help.
The tricky part is calculating the exact amount of CBD per milliliter of oil. Some tinctures have concentrations of 1,500 mg per 30 mL, while others have 3,000 mg per mL (or more).
Clinical research has shown that CBD oil can trigger side effects. The severity and type can vary from one person to the next.
CBD oil may also increase liver enzymes (a marker of liver inflammation). People with liver disease should consult their healthcare provider before taking CBD oil and use it with caution. Regular blood liver enzyme level checks are recommended.
Don't drive or use heavy machinery when taking CBD oil since some of them contain THC. This is especially important when you first start treatment or use a new brand.
What to Look For
However, there aren't many studies that examine the use of CBD in treating chronic pain in people. The studies that do exist almost always include THC. This makes it hard to isolate CBD's unique effects.
The men who took 300 mg of CBD oil showed less anxiety than those given a placebo. Interestingly, the men who took 100 mg or 600 mg of CBD oil didn't have these results.
However, CBD affected each type of addiction very differently.
Cytochrome P450 (CYP450) is an enzyme in your body that breaks down certain drugs. But CBD oil can block CYP450 from working the way it normally does. CBD oil can either make some drugs you take have a stronger effect than you need or make them less effective.
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.
