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.
The dosages used in research studies vary and there is no consensus on how much should be used for specific conditions. If you do decide to try CBD, it is also important to note that there is no universally agreed upon dose. Research also suggests that people may respond differently to various dosages, so the amount that is right for your needs might vary.
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.
In order to determine if CBD is right for you, it is important to consider its potential benefits, side effects, and available research on safe dosages.

Some people experience the painkilling benefits of CBD oil immediately, others need to take the oil for a few days or weeks before noticing any improvement.

Our dosage calculator is based on the calculations listed below. These doses are estimates and should not be used to replace professional medical advice regarding dosage.
For best results, take CBD oil first thing in the morning, and repeat around lunch time. Many people will take a mild “booster dose” about 30 to 60 minutes before engaging in activities that trigger their anxiety.
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.
For this study, nine healthy men took either 600 mg of CBD or the same dose of a placebo. According to the researcher, those treated with CBD had lower blood pressure before and after exposure to stressful stimuli (including exercise or extreme cold).
Proponents claim that CBD oil can treat a wide variety of health problems, including:
In addition, the stroke volume (the amount of blood remaining in the heart after a heartbeat) was significantly reduced, meaning that the heart was pumping more efficiently.
CBD oil should be avoided during pregnancy and breastfeeding. A 2018 study from the American Academy of Pediatrics warned women to avoid marijuana during pregnancy due to the potential risks to a baby’s development. Although it is unclear how CBD contributes, CBD is known to pass through the placental barrier.
To use CBD oil, place one or more drops under the tongue and hold the dose there for 30 to 60 seconds without swallowing. Capsules and gummies are easier to dose, although they tend to be more costly. CBD sublingual sprays are available as well.
There are no guidelines for the appropriate use of CBD oil. CBD oil is usually delivered sublingually (under the tongue). Most oils are sold in 30-milliliter (mL) bottles with a dropper cap.
CBD oil may also increase liver enzymes (a marker of liver inflammation). People with liver disease should use CBD oil with caution, ideally under the care of a doctor who can regularly check blood liver enzyme levels.
