What’s the Normal Dose of CBD?
The most common dose of CBD is 20 – 40 mg per dose. Some people take much less (as low as 1 mg), others take much higher (up to 100 mg).
Depending on the strength of the product you’re using, this could be anywhere from a few drops to several milliliters of oil. It could also involve anywhere from 1 – 5 capsules or gummies per dose.
The truth is that the optimal dose of CBD is different for everybody.
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.
The ideal dose of CBD for you depends on a variety of factors, including:
- Your size and weight
- The severity of the condition you’re treating
- Your tolerance to CBD
- Your individual body chemistry
- The potency of the CBD oil, capsules, gummies, or other CBD products you’re using
The best way to find the right dose for your body is to start with a very low dose (2 mg, for example) and increasing by 2-5 mg per dose until you find what works best for you.
CBD Dosage For Anxiety
The effective dose of CBD oil for anxiety or chronic stress usually falls on the moderate to heavy range of the spectrum.
However, some people with anxiety disorders find they’re especially sensitive to CBD may only need a small dose.
When using CBD oil to manage anxiety levels, it’s best to start with a mild dose first to see how you respond. If you don’t see any improvement, move up to the moderate dosage next. Most people notice improvement with the moderate or heavy dosage according to their weight.
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.
CBD Dosage For Pain
The dose of CBD oil for pain can vary significantly. For mild pain, such as low-grade arthritis, mild PMS pain, or low back pain — a mild or moderate dose of CBD oil will usually do the trick.
For more severe pain, nerve pain, or treatment-resistant multiple sclerosis or cancer pain — you’ll likely need to use a heavy dose of CBD oil.
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.
The time it takes to notice improvement depends on the underlying condition that’s causing the pain.
Inflammatory pain, cancer pain, or pain from endometriosis can take a long time — while arthritis pain, digestive pain, muscle pain, and PMS pain usually improve within a few hours of taking CBD oil.
For arthritis or joint pain, you can get faster effects by using a CBD pain cream alongside your CBD oil.
CBD Dosage For Sleep
CBD oil has been shown to improve both the quality and duration of sleep — but studies have shown the effective dose of CBD oil for sleep is higher than other conditions. Aim for the heavy dose of CBD oil if the goal is to improve your sleep.
Low doses of CBD (less than 10 mg) can have a stimulating effect, while higher doses (20 mg or higher) are generally much more sedative. The more CBD oil you use, the stronger the sedative effect.
Certain types of CBD extracts also tend to have a stronger impact on sleep. For example, CBD oils that contain sleep-supportive terpenes such as linalool, bisabolol, lavandin, or myrcene have the strongest sedative action.
You can also find CBD oils that contain melatonin to make the oil even better for promoting sleep.
CBD Dosage For Depression
CBD oil is useful for managing symptoms of many mood disorders — including depression.
Finding the right dose of CBD oil for depression can take some trial and error. The underlying processes that cause depression don’t happen overnight, and they won’t disappear overnight either. It can take several weeks or months of steady CBD oil supplementation — along with other lifestyle modifications — before you can expect any real improvement.
It’s best to start with a mild or moderate dosage of CBD oil for a few weeks before graduating to the heavy dose once you understand how CBD affects your body individually.
Calculating the Dose of CBD Based on Your Weight (How This Calculator Works)
While the dose of CBD is unique for everybody, there is a general rule of thumb that can be used to determine an estimated dose based on your weight and the strength of effects you’re looking for (low, medium, and high strength).
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.
I recommend you start with the low-strength dose when using CBD for the first time and increase the dose slowly over time. When you find a dose that works, you’ve found the right dose for your body. If you experience side effects, you’ve found your upper limit. Reduce the dose to the last amount that didn’t produce side effects.
Calculating the Dose of CBD By Weight & Strength:
- Low strength → 1 mg CBD per 10 pounds (2 mg per 10 kg)
- Medium strength → 3 mg CBD per 10 pounds (7 mg per 10 kg)
- High strength → 6 mg CBD per 10 pounds (13 mg per 10 kg)
It’s important to note that this measurement is in pure CBD, not CBD oil.
We’ll go over calculating how much CBD oil this dose works out to later on. Once you know how much CBD you should be using, you can find the equivalent amount of CBD oil depending on the potency of the oil you’re using.
CBD Dosage Chart by Weight & Strength (in mg)
The optimal dose of CBD depends on the combination of your weight and desired dosage.
A smaller, 90 lb woman is going to need a much smaller dose than a large 250 lb football player — for example. And someone looking for mild relief from stress or anxiety isn’t going to need a high dose like someone looking to treat persistent pain.
You can use this CBD dosage chart to visualize how the dose of CBD changes according to your body weight and desired strength of effects.

The Calculator That Shows You How to Properly Dose CBD
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.
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.
