How to use the CBD potency calculator

The potency calculator measures a product’s CBD concentration. This is important to know because products with a higher potency will have stronger effects. Potency is the concentration of CBD in a product. For oils and other liquid products, it’s represented in milligrams (mg) of CBD per milliliter (ml), whereas for capsules, gummies, and similar products it’s in mg per piece. Higher potency means greater effects.

Some people find that low-potency products don’t give them the desired effects and look for stronger options. We divide potency into three ranks: low (0-25 mg per ml/piece), moderate (25-35 mg), and high (>35 mg).

If you’re using a CBD oil, vape e-liquid, or beverage, enter the total volume in milliliters (ml) and the total amount of CBD in milligrams (mg). If you’re using gummies or capsules, switch to (pcs) and enter the number of pieces per bottle and the total CBD amount. The calculator will then show you the potency of the product in either mg per ml or mg per piece and give it a low, moderate, or high strength rank.

CBD Potency FAQ

  • What is CBD?
    CBD is a phytochemical found within the cannabis plant. CBD is short for cannabidiol, one of the two most plentiful cannabinoids found in cannabis, the other being THC. CBD interacts with the endocannabinoid system found in all animals and fish, including humans.
  • Is CBD safe?
    CBD is found to be generally safe. There have been no deaths attributed to ingestion of the cannabis plant, including CBD. The FDA has approved one CBD based drug called Epidiolex used for epileptic seizure reduction. The FDA reports that CBD can cause liver injury and interact with other medications. There have been no reports of liver injury in humans who have taken CBD even at high doses. Side effects of taking CBD may include drowsiness, diarrhea, loss of appetite, and change in mood. There is more research needed around the safety and efficacy of CBD. Consult your health care provider before taking CBD to ensure it is right for you.
  • What can CBD help with?
    The National Institute on Drug Abuse (NIDA) states CBD has been shown to reduce stress in animals including rats. Other studies show that participants with social anxiety disorder (SAD) experienced overall reduction in anxiety levels after taking CBD. CBD is also known to help with PTSD symptoms including replaying negative memories and enduring nightmares. People with anxiety may have lower levels of anandamide. Introducing CBD can help decrease the reuptake of anandamide and cause it to hang around longer which could decrease anxiety symptoms. CBD is also thought to stimulate serotonin receptors. Serotonin is a neurotransmitter that plays an important role in mental health. Having insufficient serotonin can also contribute to anxiety. This study found a significant decrease in insomnia symptoms for participants taking CBD and other cannabinoids. Research also shows that CBD inhibits inflammatory molecules in the body that contribute to pain. The Arthritis Foundation states CBD appears fairly safe and might help certain types of pain.
  • What does potency mean?
    Potency refers to the amount of CBD present in the product. For example, a one ounce 500 mg tincture is more potent than a one ounce 100 mg tincture. Since one ounce in 30 ml, a 500 mg tincture would have 16.7 mg/ml of CBD and a 100 mg tincture would have 3.3 mg/ml.
  • Why is it important to know the potency in your product?
    It is important to know the potency of your product so that you know exactly how much CBD you are getting with each dose. This will be important if your health care provider wants you to take a certain dosage of CBD. Knowing the potency of your product is also important so that you know how much CBD you need to consume in order to get the relief you are looking for.
  • Is higher potency always better?
    The short answer is it depends. If you need a higher level of CBD, then a higher potency will be best so that you can take less product to achieve the desired result. This will allow you to conserve your product, making it last longer. If you need a low dose of CBD, a lower potency may be a better option because it will be cost effective to buy a lower potency product. The potency of your selected product should be based on how much CBD is recommended for you.
