Cannabidiol (CBD) is growing increasingly popular, thanks to its many purported health benefits and non-intoxicating properties (most CBD products contain less than 0.3% tetrahydrocannabinol, or THC). In fact, 60% of U.S. adults have tried CBD at some point and believe it has medicinal benefits, according to a recent Forbes Health survey of 2,000 U.S. adults conducted by OnePoll. As research evolves and sheds light on CBD’s efficacy, especially for pain relief, more and more people are adding it to their daily wellness regimens.
Consumers can choose from a variety of CBD products, from oils to gummies to vapes to capsules. But figuring out the safe and effective CBD dose for an individual is a complex decision.

Here’s how to find the right CBD dosage for you and how to consume it safely.
Determining the Best CBD Dosage for You
With the exception of one CBD product, a prescription drug used to treat seizures associated with particular syndromes, the Food and Drug Administration (FDA) doesn’t regulate the use of CBD. (In fact, it’s illegal to market CBD as a supplement or add it to food.) Therefore, it’s best to consult a doctor with experience in CBD administration to determine your ideal dosage.
Expressed in milligrams (mg), CBD dosage largely depends on the conditions and symptoms you’re trying to treat and your unique endocannabinoid system, which is associated with motor control, behavior, emotions, the nervous system and homeostasis. CBD dosage remains an area of active research—more large, high-quality studies are needed in different populations to determine appropriate dosing, efficacy and safety guidelines.
“It’s best to start small and gradually increase your dose up to a level that gives you the desired effect,” says Cheryl Bugailiskis, M.D., a cannabis specialist at Heally, a telehealth platform for alternative medicine. Your starting point might look like half a CBD gummy or a drop of oil. Ideally, navigate this process under the guidance of a qualified physician.
If you’re still not sure where to start, mydosage.com offers a questionnaire and CBD calculator to help you based on your specific symptoms and usage goals.
How to Calculate CBD Dosage
When you consume CBD gummies, capsules or softgels, dosage is typically expressed per unit. For example, there may be 50 milligrams of CBD in each individual gummy. These products don’t offer much dosage flexibility since you can’t split up capsules easily. For instance, if one softgel capsule didn’t provide your desired result, you would have to take another full capsule, doubling the total dose.
CBD oil, on the other hand, makes it easier, to begin with a small dose. But calculating CBD oil dosage can be less straightforward. Oils and tinctures tend to come in a dropper bottle and, typically, only the total liquid volume and CBD contents are listed on the label. For example, the label might simply state there’s 1,500 milligrams of CBD in the 30-milliliter bottle.
But what does 1 milliliter look like? Due to the current lack of regulation of CBD, this calculation can be tricky. Start by figuring out the volume of a single drop in your dropper, which is usually 0.05 milliliters, according to Dr. Bugailiskis. If you’re unsure, ask the company.
Here’s where math comes in. Let’s continue with the 30-milliliter bottle with 1,500 milligrams of CBD and 0.05 milliliters in a single drop as our example.
1500mg÷30mL = 50 mg/mL
This bottle contains 50 milligrams of CBD per milliliter. Let’s see how many milligrams are in a drop:
50mg/mL ×0.05mL/drop = 2.5mg/drop
Each drop contains 2.5 milligrams of CBD.
Next, you can calculate how many drops you need to reach your goal dosage. Let’s say you want to consume 25 milligrams each day.
25mg÷2.5mg/drop = 10 drops
10 drops ×2.5mg = 0.5mL
With this CBD oil dosage calculator as your guide, you would find that you needed to consume 10 drops, or 0.5 milliliters, to reach 25 milligrams. And if you intend to consume 25 milligrams daily, you can expect this particular bottle to serve as a 60-day supply.
Some CBD products do some of this math for you and illustrate how many milligrams are in a milliliter, some even marking these points on the dropper so you know exactly what you’re taking.
CBD Dosage for Different Ailments
Without FDA approval, there is little guidance in the U.S. on how much CBD a person should consume for various conditions.
In many medical studies on CBD, you see administered doses reach hundreds of milligrams a day, which sounds severe compared to our starting dosage example of 25 milligrams. However, Steven Phan, founder of Come Back Daily, a CBD dispensary in New York, points out that patients in these studies are often dealing with serious flare-ups and pain-inducing conditions compared to everyday dispensary customers.
Below are clinically-studied CBD dosages based on different ailments and conditions. Note: Some of the formulations studied contained THC as well—not all available dosage research sticks strictly to CBD.
*Dosages are based solely on small, short-term clinical study results where CBD proved significantly successful over placebo. Much larger studies are needed to further strengthen the evidence.
FDA-approved Epidiolex administers CBD orally as a liquid to treat seizures associated with Lennox-Gastaut syndrome, Dravet syndrome and tuberous sclerosis complex. The dosage of Epidiolex is determined by taking the patient’s weight in kilograms (kg) into account.
Several countries, including Canada and those in the U.K., have approved the use of Sativex, an oral spray with equal amounts of CBD and THC, to treat pain stemming from multiple sclerosis. Canada has also approved it for treatment of cancer pain.
The medical and research community still has a long way to go before figuring out what dose works best for each condition. At an individual level, consumers can experiment with caution until they find what works best for them.

How to Take CBD
Popular ways to take CBD include:
- Oils and tinctures (extracts of plant material dissolved in ethanol): A liquid that comes in a bottle with a dropper
- Gummies: A soft, chewable candy that’s often fruit-flavored
- Sprays: A liquid that comes in a bottle with a nozzle for spraying into the mouth
- Capsules: Tablets or softgels that are ingested by mouth
- Vapes: CBD oil that’s heated without ignition, resulting in an inhalable vapor
- Flower: Dried hemp plant that’s often ignited and smoked
- Edibles: Any food that CBD oil has been added to, such as brownies or chips
- Drinks: Any beverage that’s infused with CBD, often in the form of hemp extract
Your CBD product of choice will largely depend on your personal preferences, as well as your budget since prices vary depending on the potency of ingredients and manufacturing processes. Different mediums also offer varying levels of bioavailability—or how much of what you take is actually absorbed into your bloodstream to have an effect. For example, if you ingest 10 milligrams of CBD via 1 milliliter of liquid, your body might absorb about 60% of it, or about 6 milligrams.
Cannabinoids generally have a low bioavailability compared to other substances, according to Jordan Tishler, M.D., a physician specializing in cannabis treatment in Massachusetts. However, “products that contain emulsifiers like egg yolk (brownies) or lecithin (some gummies) do better,” he says.
With that said, ingesting CBD via gummies or other edibles may take longer to take effect since the CBD has to travel to your digestive system to be broken down and absorbed.
Can You Take Too Much CBD?
Like with any substance, you can take more CBD than your body can handle. Studies show doses up to 1,500 milligrams a day have been well-tolerated, but every person is different  Bergamaschi MM, Costa Queiroz RH, Zuardi AW, Crippa JAS. Safety and side effects of cannabidiol, a Cannabis sativa constituent. Current Drug Safety. 2011;6(4):237-49. . Ingesting too much CBD can cause unpleasant side effects, such as dry mouth, nausea, diarrhea, upset stomach, drowsiness, lightheadedness and general disorientation. While rare, liver damage can also occur.
What’s more, CBD can have serious interactions with certain medications. In evaluating available information on five prescription CBD-based medications, researchers found 139 medications could have a potential drug-drug interaction with CBD  Kocis PT, Vrana KE. Delta-9-Tetrahydrocannabinol and Cannabidiol Drug-Drug Interactions. Medical Cannabis and Cannabinoids. 2020;3:61–73. . People who take certain blood thinners, heart rhythm medications, thyroid medications and seizure medications need to be particularly careful.
At the end of the day, not all supplements are created equal, which is why it’s important to work alongside a health care provider when adding CBD to your wellness regimen and research reliable brands. And while emerging research and anecdotal evidence is promising, more large, randomized-controlled trials are needed to further understand the benefits of CBD and its dosing.
1,500mg Broad Spectrum CBD Oil
Our 1,500mg CBD Oil contains 50mg per 1mL (bottle size is 30mL) and is perfect for those people who have a more serious case or if their body naturally requires higher doses. Our CBD tinctures are mixed with organic MCT Oil (from coconut), a healthy fat called medium-chain triglycerides that converts into energy your body uses. MCT’s also have a variety of health benefits.
Start by using 1-2 servings per day (50-100mg of CBD) for the first 7 days and see how you feel. If you’d like, you may increase the dose slowly. However, if you suddenly don’t notice a difference or effect, it means you built a tolerance. If so, we recommend taking a 3-day break and starting at a slightly lower dose than before and, if needed, increasing the dose slowly to find your optimal dose.

- Be consistent in taking it every day.
- Shake bottle before opening
- Fill dropper to desired serving size.

Frequently Asked Questions
How to use this CBD Oil tincture?
Using CBD oil tincture is a breeze. Our measured dropper tells you exactly how much you’re taking, allowing for better dose control.
To take the tincture, just follow these quick steps:
- Gently shake the bottle
- Place dropper inside the oil, then squeeze and slowly release the rubber bulb

What are the benefits of CBD Oil tinctures?
There’s a long list of benefits with CBD oil tinctures. Some include:
- Precise dosing with our marked droppers
- Easily mixes with drinks, smoothies, and anything else you see fit
- Faster action compared to other oils and edibles
- General wellness for your body and mind
How much of this 1,500mg CBD oil should I use?
This all depends on your case, but you may start with half a dose, which is 0.5mL, or a full dose of 1.0mL.
Start with 0.5mL to 1.0mL for the first 5-7 days, and if needed, you may increase your dose by 0.5mL every 3-4 days per day to find your “sweet spot.”
If you feel you need a higher dose from the start, of more than 1.0mL per day, by all means, you may do that.
One thing to note is that you may build a tolerance to CBD, where the effects are not as noticeable as before or that you don’t feel it at all, and it’s 100% normal. If this happens, take a 2-4 day break, and start back at a lower dose. This will allow your body’s tolerance to reset.
Other CBD dosing tips:
- Take regularly in order for the CBD to accumulate in your system
- Be patient. The best goals take time and precision. Most people notice effects in a few days. A fewer number of people report waiting two to four weeks.
- Avoid consuming on an empty stomach, as research shows food can exponentially improve absorption.
How to know how much CBD you’re taking?
Each 30ml bottle includes a handy dropper with marked measurements at 0.25ml, 0.5ml, 0.75ml, and 1.0ml for precise dosing.
For this 1,500mg CBD Oil:
- 0.25mL contains 12.5mg of CBD
- 0.5mL contains 25mg of CBD
- 0.75mL contains 37.5mg of CBD
- 1.0mL contains 50mg of CBD
How long does it take for CBD Oil tinctures to work?
CBD oil tinctures are the fastest option for oral administration. Unlike regular CBD oil and edibles such as gummies or softgels, tinctures partially absorb through capillaries in the gums, cheeks, and tongue. This allows some of the CBD to directly hit the bloodstream before the rest metabolizes through the liver. As a result, tinctures take effect within 15-20 minutes.
Gummies, conventional oil, and softgels (among others) only go through your digestive tract. It takes a minimum of 30-45 minutes to make the trip from your stomach to the bloodstream.
