No matter where you go, the odds are that a CBD product is nearby. Now sold at gas stations, drugstores and grocery stores, CBD seems to be everywhere due to its reported health benefits around chronic pain, sleep and anxiety. However, it’s important to know that the FDA has only approved one cannabis-derived drug product (with a prescription). Plus, according to a Penn Medicine study, almost 70% of CBD extracts sold online are mislabeled.
It’s no wonder why there is so much confusion surrounding CBD. To help you sort through the noise, we spoke with experts to learn more about CBD and how to find the right dosage.
What can CBD be used for?
Research, though limited, indicates that CBD has legitimate health benefits. While there is no FDA regulation, research has shown that full-spectrum and broad-spectrum CBD effectively treat pain and anxiety. There’s only one FDA-approved CBD product, called Epidiolex, that’s available by prescription. Epidiolex treats seizure disorders such as Lennox-Gastaut syndrome and Dravet syndrome.
However, there are several other benefits and uses of CBD products.
The most common uses of CBD
To lessen symptoms of anxiety and depressionPain relief for things like muscle pain or migrainesImproving sleepTo reduce chemotherapy-induced nausea Relieve inflammatory diseases Help with behavioral symptoms of dementia or Alzheimer’s diseaseManaging multiple sclerosis and improving mobility
The CBD market is continuously expanding with new products. However, there are four main types of CBD product categories. All of which will vary in potency and dosage per unit.
Oils and tinctures
CBD oils generally come in either a liquid or capsule form. You can take the extracts independently or use the dropper to add them to food or drinks. Liquid tinctures are usually taken directly under the tongue.
“Tinctures are generally taken at higher concentrations than oils. This means that if you were taking 1 milliliter of tincture, you would need to drop the concentration down to 0.5 milliliters. A good rule of thumb is to start with a small dose (0.25 milliliters) and slowly increase your dose over time,” says Reda Elmardi, a registered dietician and certified nutritionist.
Edibles
Edible CBD products are quickly becoming very popular, likely because of their convenience and flavor profiles. With edibles, you have several options in flavor, potency and price. They have everything, from gummies to cookies, chocolates and even granola bars.
Topicals
CBD is also available in topical creams and salves that can be applied directly to the skin. Popular forms are lotions, creams or ointments. Topical CBD products are good options for muscle pains, joint inflammation or nerve pain.
Topical CBD is one of the more difficult forms for determining dosage. Not only does potency vary by product, but also varies by how much you use each application. It’s important to follow manufacturer instructions carefully.

How to find the best CBD dosage for you
CBD products express dosage in milligrams. Epidiolex starts with a dosage of 2.5 milligrams taken twice a day. After a week, you can increase the dosage to 5 milligrams twice a day. Federal regulation makes determining dosage straightforward.
For the rest of the products on the market that are not regulated by the FDA, there are no established guidelines for CBD concentration, which makes determining how much you should take a little more difficult. There are a few key factors you need to keep in mind: your weight, what you’re treating and the concentration of the product.
The ideal dosage for you will vary depending on what you’re using it for and what form you’re taking. Don’t forget that different forms also mean how quickly it takes effect. Generally, edibles, oils and capsules will take roughly 30 to 60 minutes to take effect. Smoking or vaping CBD will bring it on significantly quicker since the CBD absorbs into your bloodstream rather than your digestive system.
CBD dosage will vary by condition
In general, the CBD dosage is dependent on the disease and its ability to be managed by CBD. The research that is available on CBD treatments has very varied dosage levels. Clinical studies have varied in oral doses from 100 to 800 milligrams a day. Others administer lower levels around 40 milligrams. A 2019 study investigating CBD for anxiety found that 300 to 600 milligrams reduced anxiety symptoms. However, that study was limited to 57 adult males.
“For generalized anxiety or sleep disorders, 25 to 75 milligrams per day is recommended, while for PTSD, 33 to 50 milligrams per day is recommended. In severe anxiety, a patient’s dose might be increased to 300 to 600 milligrams. If the patient is experiencing pain due to chemotherapy, 50 to 60 milligrams is recommended, with a maximum daily dose of 600 milligrams,” says Kimberly Langdon, a board-certified doctor.
How much CBD is best for you will depend on your body. Your body weight and existing medications will influence the ideal dosage.
Can you take too much CBD?
A clinical review of studies confirmed that people tolerate doses as high as 1,500 milligrams a day. We want to stress that the research around CBD dosage is still really young, so there is not much to point to about how much is too much for people. More research is needed to definitively conclude the ideal dosage for each condition.
Not a ton of known side effects associated with CBD products. Though fatigue, diarrhea and appetite changes have been reported. The FDA states that CBD can cause liver damage and potentially impact the other prescription medications you’re taking. If you’re starting your CBD journey, it’s best to slowly build your dosage so you can monitor how it affects you.
“The idea is to start very low (i.e., 5 milligrams per use) and increase daily usage by 5 milligrams every two days until you start feeling results. Then, stop increasing and keep using the same number of milligrams or drops. For many people, the amount that provides modest benefits in the first couple days will, after consistent use, provide more and more benefit over time,” says Dustin Sulak, an integrative physician and leading cannabis clinician.

How to calculate CBD dosage
For some forms of CBD, determining how much each unit is is simple. Capsules or gummies tend to have an expressed milligram content, making dosage much easier than oils or creams.
Oils or tinctures with a dropper bottle list the CBD content for the total liquid bottle. So instead of eating a gummy that’s 50 milligrams, it will look more like 7,500 milligrams of CBD in the 30-milliliter bottle. Some bottles will offer serving sizes — like one drop — to indicate dosage. This allows you to have greater control over how much you are taking, but even still, it’s not a perfect science.
Some bottles with a traditional nutrition label on the back will tell you exactly how much is in one dropper. If you are unsure, it’s a good idea to contact the company to find out. It can be difficult to figure out how much you’re intaking for the bottles that do not break down by serving size and offer only the total amount. It is difficult, but not impossible. It just takes a little bit of math.
Say you have a 30-milliliter bottle of CBD oil, and each drop is 0.05 milliliters.
To determine how many milligrams of CBD per milliliter, you divide the total milligram content by how much the bottle is. In this example, the math would look like this:
7,500 milligrams divided by 30 milliliters = 250 milliliters.
There is 250 milligrams of CBD per milliliter for this product. Next, you want to know exactly how much CBD is in each drop.
250 milliliters x 0.05 milliliters = 12.5 milliliters per drop.
This calculation works with any bottle of CBD. Once you know how much CBD is in each drop, you can accurately take your ideal amount. “To ensure the best results, keep track of how much you take, how many times a day you take it and rate your symptoms daily (by rating 1 to 10, 10 being best) to see if they are getting better or worse,” Sulak advises.
Too long, didn’t read?
CBD is a continually evolving field in both products and research. While research is lacking, what is available suggests that CBD does have therapeutic benefits and is generally very well tolerated by people. Still, more research is needed to really dig into the long-term side effects and best dosage markers for the average person.
In place of federal regulations, use your best judgment regarding how much CBD you are taking. Talking to your doctor about dosage is always a good idea when in doubt.
