It’s common for two people with identical weight to respond very differently to the same dose of CBD. One person may find the ideal dose for them is 30 mg of CBD, while the other responds better to just 10 mg.
The most common dose of CBD is 20 – 40 mg per dose. Some people take much less (as low as 1 mg), others take much higher (up to 100 mg).
CBD Oil Dosage Calculator
The optimal dose of CBD depends on the combination of your weight and desired dosage.
It’s best to start with a mild or moderate dosage of CBD oil for a few weeks before graduating to the heavy dose once you understand how CBD affects your body individually.
You can also find CBD oils that contain melatonin to make the oil even better for promoting sleep.
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.
Some of the most common side effects that people experience when taking CBD include:
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.
Is It Possible to Take Too Much?
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.
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.
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.
There have been a number of studies that suggest that CBD may have a number of different physical and mental health uses. However, more research is still needed to better understand the substance’s potential applications and possible long-term side effects.
Remember, because CBD oils are largely unregulated, there is no guarantee that a product is either safe or effective.
CBD is the short name for cannabidiol, one of the two chemicals—among the dozens in cannabis—that have the most health benefits. The other, tetrahydrocannabinol (THC), produces the psychoactive effects described as being “high.” CBD oil generally does not contain THC, although some trace amounts may be present in products sold in certain states.
Clinical research has shown that CBD oil can trigger side effects. Severity and type can vary from one person to the next.
What to Look For
In June 2018, the U.S. Food and Drug Administration (FDA) approved Epidiolex, a CBD oral solution used for the treatment of certain rare forms of epilepsy in children under 2—Dravet syndrome and Lennox-Gastaut syndrome. Both are exceptionally rare genetic disorders causing lifelong catastrophic seizures that begin during the first year of life.
Potential drug-drug interactions with CBD include:
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).
CBD shows promise in the treatment of anxiety disorders, suggests a 2015 review of studies in the journal Neurotherapeutics. According to the investigators, CBD demonstrated potent anxiolytic (anxiety-relieving) effects in animal research, albeit with counterintuitive results.
