How Much CBD Oil Should I Take?
One of the most common complaints we hear about CBD is not that doesn’t work, but that figuring out the right dose can be a real pain. So we created a CBD dosage calculator that figures it all out for you and makes dosing incredibly easy. Make sure that when you are entering in your information that you only enter numbers. If you enter letters (oz, mg, lbs), then you will not get a reading and it will say Naan.
Our calculator will show you:
- Your suggested minimum, average, and maximum daily dose based on your weight.
- How much CBD is in a single drop and how many drops you’ll need for the above doses.
- The concentration of your CBD bottle and how many drops your bottle has in total.
It’s safe to say our CBD dosing calculator shows you a lot, but don’t worry it’s incredibly easy to use.
All you need is three easy to find numbers, and in three steps you’ll be on your way:
- The first step is to input the size of your bottle in ml.
- Second step you’ll want to enter the total mg of CBD that is in the bottle.
- Last, you’ll need to enter your weight.
If you’re not sure what your weight is, that’s completely fine as long as you have a general guesstimate and preferably are using full spectrum CBD oil.
Dosing with full spectrum CBD oil allows you to work within a ballpark, so even when your dosage is off, you’re still rewarded with numerous therapeutic benefits.
Welcome to better health with CBD oil.
What dosing with CBD looks like?
There are so many ways people use CBD, and much of it comes down to personal preference and experimenting around to find what best works.
You can apply CBD in a number of ways, with different dosages for different medical conditions and it can really make your head spin. So let’s break it down in simple steps.
Use these steps as jumping-off points and feel free to customize any step for better CBD therapy. How much CBD you take and when, really comes down to what works best for you.
If that’s 5 mg for preventive health, that’s wonderful. If it’s 30 mg multiple times a day, that’s just as awesome.
Step 1. If you’ve never used CBD before try our Full Spectrum PurCBD+ Oil . This form offers a few extra benefits and makes up the bases for most other forms of CBD.
Step 2. Use our CBD dosage calculator and start in low dosing tier once or twice a day for the first week. Low tier = 0.022mg/lb or 0.05.mg/kg
Step 3. After week 1, feel free to increase your dose as needed. You can experiment by doubling or tripling your first-week dosage. You’ll likely find a certain amount were taking more CBD doesn’t really help that much more.
Pretty simple right! We recommend the oil form for first timers because when you hold it on or under your tongue for 30-60 seconds, you greatly speed up the rate when effects are felt.
This is great for judging how CBD is working for you. Plus, you can slowly increase your dose in small increments.
We always recommend using our CBD dosage calculator whenever changing your CBD dosage.
However, we don’t recommend this because of the dangers associated with high dosages.
Instead, we find that most people like having a few different dosages that they take depending on the severity of their medical condition on any given day.
For example, they may take a 15 mg CBD dosage for anxiety to help prevent it. However, if they are experiencing an anxiety attack, they may use 30 mg or more.
What happens if you take too much CBD?
The most likely thing that will happen is just a more potent and relaxing CBD session. There is a good chance you may feel tired if you go over 100 mg, but this isn’t a guarantee, and no harm comes from this side effect.
If your body isn’t used to taking CBD, throwing a lot at it can make your stomach upset. This is a normal biological response whenever something foreign enters the body the first few times, and once the stomach realizes CBD isn’t an irritant, nausea should pass.
CBD is a known inhibitor of CYP450 enzymes
This is the one side effect of concern and it only applies when taking a prescription drug metabolized in the liver. CBD inhibits CYP450 enzymes. Kale and turmeric can inhibit these same enzymes, along with grapefruit , red wine, and St John’s Wort.
When you inhibit CYP enzymes, you risk delaying the breakdown of drugs metabolized in the liver — about 50% of prescription pharmaceutical. By delaying their breakdown you raise their potency.
This is the one side effect of concern, and it only applies when taking a hepatic drug (metabolized in the liver).
How much CBD for anxiety, pain, epilepsy, and more?
This is one of the most asked questions we get, and we have an easy answer.
After your first week using a low tier dose of CBD, you’ll have a much better idea of how CBD works and feels. From here, many with chronic health conditions will jump up to a medium tier dosage and find that it equally helps with their anxiety, inflammation, appetite, etc. A generic average dose is 15-30 mg a day.
If you’re looking to treat chronic insomnia that isn’t related to external sleep disturbances — like pain, mood, etc. — a strong tier dose is recommended.
For the average person, this is anywhere over 100 mg — if you describe yourself as petite or are on the shorter/skinner side, you may feel tired with doses lower than 100 mg.
Remember, unless you’re on dosage sensitive drug metabolized by CYP enzymes, you will likely not run into any side effects even when taking several hundred milligrams of CBD a day.
Does dosing change when using different versions of CBD?
Yes, and no. The amount of CBD you find works best for you will likely not change when jumping between tinctures, capsules, or edibles.
The tincture can absorb into the bloodstream through the mucous membrane of the mouth — this greatly speeds up CBD start time and looks like it increases its bioavailability.
The former advantage is why many go with tinctures. The latter works in principle, but most people don’t seem to notice an issue with their dosage when changing to a version that passes through the digestive tract first like capsules.
When it comes to choosing which CBD is right for you, it really comes down more to personal preference. So let’s see which of our CBDs works best for your needs.
Choosing Which CBD is Right For You
Tinctures ( Full Spectrum PurCBD+ & PurCBD+ Isolate )
If you want precision dosing and fast relief, you want the original and standard CBD oil. You may feel CBD working with 5-20 minutes, and you can easily dose at whatever amount you prefer — be it 1 mg or 73 mg.
Full Spectrum: Right off the bat, if you’ve never used CBD before and don’t consider yourself a very picky eater we recommend Full Spectrum PurCBD+.
Full spectrum dosing works like climbing stairs — take more, and you’ll feel more. With the next form, you have to hit within a dosing window, which is unique to you and this takes trial and error.
We offer our Full Spectrum PurCBD+ in three different concentration sizes, and our CBD oil dosage calculator will help point you in the right direction. If you’re looking for just a bit of CBD go for a smaller size.
If you need to take a lot, grab a more concentrated version so you’re not consuming a lot of oil. Here is a chart to see how CBD is in each version.
How many mg in a drop of CBD:
- PurCBD 250 MG: 1 drop = 0.18 mg CBD
- PurCBD 750 MG: 1 drop = 0.54 mg CBD
- PurCBD 1500 MG: 1 drop = 1.08 mg CBD
Nano-enhanced CBD Isolate: U nlike full spectrum, CBD isolate doesn’t have the other molecules found in hemp that increase CBD’s bio-absorption.
We’ve nano-enhanced our CBD Isolate oil to improve CBD’s absorption in the body so unlike other isolates you have a much better chance at feeling CBD’s full effects.
It can still be tricky so we suggest full spectrum first because as long as you take enough, you’ll always feel it helping.
However, in rare cases, some people feel tired with full spectrum CBD at even with lower doses — the thought is they are more sensitive to one of the other phytocannabinoids in full spectrum.
Isolate provides you with two ways to avoid this:
- First, you can just take CBD isolate on its own which is only CBD.
- Second, you can boost the ratio of CBD to other cannabinoids by taking both isolate and full spectrum together.
Capsules (PurHemp Gold Extra Strength)
If you hate the taste of oils, capsules offer a great way for you to still enjoy CBD. Their biggest pro is they are flavorless and easy to take. A disadvantage is capsules will offer a one-size-fits-all dose at 15 mg per capsules.
But a majority of people don’t mind this at all and many find 15 mg and 30 mg perfect amounts for both mild and severe chronic conditions, respectively. In fact, this is why you see most CBD capsules on the market contain 15 mg a piece.
In our opinion, the only big negative is they can take up to an hour before providing relief. However, with an empty stomach, effects can be felt in just 30 minutes.
This is just like taking an over-the-counter medication in pill form, so most have no issues waiting up to an hour.
Topicals (CBD Skin Care)
Here’s where you can pretty much forget about how much CBD to take. Topicals will directly target the area they are applied to, and relief can happen within 10-20 minutes. Simply apply more CBD cream if needed.

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.
CBD Dosage Chart & Calculator
CBD dosage calculators & charts are essential to helping you find the right amount of CBD for you or your pets. CBD has made headlines for years now, ever since it was mostly legalized through the signing of the 2018 Farm Bill. Yet many people are still unaware of what it is, what it’s recommended for, and even what it’s really called. CBD is short for cannabidiol, which is just one of over 80 known compounds in marijuana. It’s also one of the main compounds found in hemp. It’s the CBD in hemp that is of interest to people who want its potential positive effects without the signature high from marijuana. Of course, CBD only has a chance to provide possible benefits if it’s used in the right dosage. Here’s what you need to know about CBD dosage before giving it a try.

CBD Dosage Calculator
Our CBD dosage calculator below provides a very general range of dosage suggestions. Many people only need a few dozen milligrams of CBD at first, while others may need to start out at a few hundred at a time to see any results. The exact conditions you have affects the suggested dosage in many ways. Consider using our reliable CBD dosage calculator to make sure you’re getting a customized recommendation.
Adjusting your CBD dosage as you experience different effects will help you narrow down your own personal best range for daily use. With conditions like arthritis or anxiety, you may need different dosages on different days. Try our CBD Dosage Calculator.

How Are CBD and THC Different?
THC is the cannabinoid that receives the most attention for its effects. However, it’s only found in high concentrations in marijuana. The main difference with hemp plants is that they don’t produce much THC. Instead, many varieties are rich in CBD. CBD offers many potential positive effects without the noticeable high that comes from THC, which may include:
- Pain relief
- Reduced inflammation
- Anxiety management
- Nausea reduction
Before worrying about a specific CBD oil dosage, it’s important to know that the products you’re choosing are safe. When CBD is properly extracted from hemp, it is believed to be safe according to current studies on its effects on human health. However, these studies are limited. Within the next few years, more studies will complete and publish research that helps us understand exactly how to best use CBD and its long-term safety. The main concern is for people taking blood-thinners, who should avoid CBD products of all kinds.
Is CBD Legal in Your Area?
Don’t make the assumption that the legalization of medical or recreational marijuana in your state means it’s legal to buy every form of CBD. CBD products were made federally legal to sell and buy in 2018 by that year’s Farm Bill. However, the states still retain the right to limit the purchase of CBD any way they want. Some states have made it illegal without a license or prescription, which complicates the matter since the FDA has only approved one CBD-based treatment to date. Check into the legal status of CBD in your area before assuming it’s available without limitation.
Long-Term CBD Use
CBD oil dosage can be tricky to get just right. Not only do you want to take enough CBD on a daily basis that you receive any possible positive effects, but you want to avoid taking too much. Higher than necessary doses of CBD oil run the risk of negative side effects and is a waste of your money. Getting the dose just right is the key to safe long-term CBD use as well. Don’t be afraid to adjust your CBD oil dosage over time or as your condition fluctuates to help you get the best effects from it.
Choosing the Right Form of CBD
Aside from the precise CBD dosage you need for your condition, you also need to consider the format you take it in. As of 2021, CBD is not allowed to be considered a dietary supplement by the FDA. However, it can be used for “cosmetic purposes” with no specific claims to any health benefits. This leaves you deciding the right delivery method for your needs on your own. The following tips should help you choose the type of CBD oil product that will work for you:
- CBD Oil: The direct extraction of the compound from hemp mixed with a carrier oil. May be unflavored or flavored, isolate or broad spectrum.
- CBD Tincture: A mixture of the extracted CBD oil and an alcohol base. Easier to mix into drinks and food than oil. May also be called drops.
- Patches and Creams: Releases CBD through the surface of the skin, usually for direct application. Works well for conditions like arthritis.
- Vapor Liquids or Cartridges: Designed for vaporizing to help the body absorb the CBD as quickly as possible.
- Gummies, Candies, and Baked Goods: Easy to eat but slower to kick in than other methods. Must be kept away from kids and pets who shouldn’t ingest large doses of CBD.
- Powders and Capsules: Either mix the dry CBD powder into your food and drink or try it contained in a capsule for mess-free dosing on the go.
CBD Dosage Chart
CBD dosage is generally calculated by the day based on the weight of the person taking it. The following CBD dosage chart is based upon recommendations from multiple sources. The wide ranges are due to more than just weight variations. Some conditions call for using lower amounts of CBD than others. Start at the lowest range listed for your weight and work your way up slowly to avoid negative side effects or wasted CBD.
- 80 to 100 lbs — 180 mg to 450 mg
- 100 to 120 lbs — 225 mg to 545 mg
- 120 to 140 lbs — 272 mg to 636 mg
- 140 to 160 lbs — 318 mg to 727 mg
- 160 to 180 lbs — 363 mg to 818 mg
- 180 to 200 lbs — 409 mg to 909 mg
- 200 to 220 lbs — 454 mg to 600 mg
- 220 lbs and above — Up to 600 mg per day
These amounts are based on the FDA’s recommended dosage for the only approved CBD-based treatment for epilepsy, Epidiolex. They’re a good place to start, but you will need to experiment on your own to see what works best for other conditions like chronic pain, fatigue, insomnia, anxiety, and more.
