CBD Dosage: How Much CBD Should I Take?

The optimal dose of CBD depends on your weight and the potency of the oil you’re using.

Everybody’s been talking about CBD oil and its long list of health benefits. You’ve shopped around and found a high-quality CBD oil to start yourself off with and you’re ready to get started.

So now what?


How much do I take? Can I take too much?

In this article, we’re going to talk about dosing CBD oil. We’ll cover how dosing can vary depending on factors like weight, age, the condition you’re treating, the potency of the oil you’re using, and more.

You’ll learn how to find the best dose for your body, and what to do if you experience side effects. 



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 CBD oil. 

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 oil, 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 NATURE SCIENCE ANMA DOL CBD cream alongside your CBD oil.


CBD Dosage For Sleep

NATURE SIENCE ANMA 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.



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 Nature Science Absolute 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

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).


These doses are estimates and should not be used to replace professional medical advice regarding dosage.

We 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.

What CBD Strength Should I Use?

The more CBD you take, the stronger the effects. Some conditions require relatively strong CBD doses to offer any benefit — others may only need a low strength to provide notable results.

Ask yourself, “what am I using CBD oil for?”

This is an important question to ask because it will guide you in the direction of the right dose to take.


Recommended Strength by Condition:


  • CBD Anxiety → medium to high strength
  • CBD Arthritis → medium to high strength
  • CBD Cancer → high strength or pharmaceutical grade
  • CBD Chronic pain → medium to high strength
  • CBD Colitis & Inflammatory Bowel Disease → medium to high strength
  • CBD Epilepsy → high strength or pharmaceutical grade
  • CBD General health → low strength
  • CBD High blood pressure → medium to high strength
  • CBD Migraine headaches → low to high strength
  • CBD Muscle recovery → low to medium strength
  • CBD Nausea → low to medium strength
  • CBD Polycystic ovarian syndrome (PCOS) → low to medium strength
  • CBD Premenstrual Syndrome (PMS) → low to high strength
  • CBD Insomnia → medium to high strength
  • CBD Weight loss → low to medium strength



Dosing CBD: 4 Steps to Finding the Perfect Dose of CBD Oil

You can use the calculations listed above to find the dosages based on your weight.

From here, you can gradually increase the dose each day until you find relief from symptoms or experience side effects (usually fatigue or grogginess). If you experience side effects, reduce the next dose to the last amount that didn’t cause any negative effects.

Never start at the high strength if you‘ve never used CBD oil before.

If you want to get even more accurate with your dosing, follow the four steps below.


Step #1: Find Your Optimal CBD Dose

The first step is to find the ideal starting dose of CBD to use. This is based on your weight.


Here’s the General Rule of Thumb for CBD Dosing According to Weight & Strength


Weight Metric

Low Strength

Medium Strength

High Strength

Imperial (pounds)

1 mg  every 10 lbs. (0.1 mg/lb)

3 mg every 10 lbs. (0.3 mg/lb)

6 mg every 10 lbs. (0.6 mg/lb)

Metric (kilograms)

 2 mg every 10 kg. (0.2 mg/kg)

7 mg every 10 kg. (0.7 mg/kg)

 13 mg every 10 kg. (1.3 mg/kg)



How To Calculate Dose From Your Weight


If you prefer metric, the formula changes only slightly:



Here’s an example of this in practice:

Let’s say you’re a 170-pound male, and you’re looking for a medium strength dose.

All you need to do is multiply your total weight (170 pounds) by the desired dose equivalent (0.3 mg per pound for medium strength).

[170] x [0.3 mg] = 51 mg CBD

So a good starting dose for you would be about 51 mg CBD per day in this case.

How much CBD oil is this? Next, you need to figure out how much CBD oil you’ll need to achieve this dose. You can measure this in drops or milliliters of oil.


Step #2: Determine the Potency of Your CBD Oil

The potency of the oil you’re using has a direct impact on the amount you’ll need to reach the optimal dosage.

For example, a high-strength CBD oil containing 1500 mg of CBD per ounce will require ten times less oil to reach a given dose of CBD than a low-potency oil with just 150 mg per ounce.

You’ll need to know how much CBD is provided in every milliliter of oil.

We make this super easy for you and tell you the concentration of CBD per mL of oil directly on the bottle. Other times, this information isn’t provided, but the formula to find the concentration of an oil is very simple to do yourself.

Here’s What You Need to Take Into Account:

  • Bottle size (in mL)
  • Amount of CBD listed on the bottle (300 mg, 600 mg, 1000 mg, etc.)

Use This Formula to Calculate Potency:



Let’s use an example.

A hemp oil that advertises 600 mg per bottle. The bottle size is 1 ounce (30 mL).

Let’s put this into our formula:

[600 MG] ÷ [30 ML] = [20 MG/ML CBD].

Our Answer: 20 mg CBD for every 1 mL of liquid.

Now that you know how potent the oil is, you can determine how much you need to get a specific dose.

For example, if you want a dose of 20 mg CBD, take 1 milliliter of oil — which conveniently works out to one full dropper. If you want 10 mg, take half a dropper. For 30 mg, take one and a half droppers, and so on.



Step #3: Convert the Dose into Drops (Optional)

To make dosing easier, you can convert your dose into drops next. The number of drops you need to hit the dose will depend on how potent it is.

Knowing the drop dosage is useful when working with high potency CBD oils. It’s also useful if you’re using ANMA PET (CBD oil for pets) or with children where even slight changes in the dose can make a big difference.

Most droppers dispense 30 drops for every mL of oil — so you can find the dose per drop by dividing the dose per mL by 30.


Here’s the formula:


Using our example from above, which was a 600 mg CBD oil in a 1 ounce (30 mL bottle). The potency of this oil was 20 mg per mL, so we can calculate the CBD dose per drop by dividing this number by 30 (30 drops in 1 mL):

[20 MG PER ML] ÷ [30 DROPS] = 0.7 MG CBD PER DROP


How to Find the Number of Drops of CBD Oil You Need Based On Your Target Dose:

You can use all this information to find the number of drops needed to reach the target dose.

All you have to do to find the exact number of drops needed to get your dose of CBD is divide the total dose by the potency per drop of CBD oil:


Using our example from before, the calculation would look like this:

[51 mg] ÷ [0.7 MG/DROP] = 73 Drops of CBD Oil




Step #4: Tweak The Dose To Match Your Body

The steps listed above will help you find the ideal target dose in pure CBD and how much CBD oil you need to take to reach that dose.

The next step is to start taking this dose and slightly tweak the amount every day until you find what works best for you.


This is one of the most important steps.

As mentioned earlier, everyone responds to CBD oil differently. This means that you need to assess how it affects you individually, rather than going off the experiences of everyone else.

Your friend may find the right dose at 20 mg, while you may require far more or far less.

The only way to really identify this is to start with the dose calculated above, and then tweak it from there.

Perhaps you took 20 mg and didn’t find any relief in your symptoms — the logical step is to increase it to the next strength tier and reassess again.

In our example, we went with the medium strength — for the next dose, calculate the higher strength (6 mg per 10 pounds) instead;

[170] x [0.6 mg] = 102 mg CBD

Or perhaps you took the 20 mg and found excellent relief, but became a little too drowsy as a result, now it’s time to tweak the dose to a slightly lower amount.

This process is never finished — you’ll always be reassessing how it affects you and changing the dose slightly to accommodate.



Pro Tip: Match the Potency of the CBD Oil With Your Estimated Target Dose

CBD oils come in a wide range of potencies. It helps to match the potency of the oil with the most likely dose you’re going to be using.

For example, you wouldn’t want to use an ultra-high potency CBD oil if you planned on using a low dose of just 5 mg per dose. Each drop of oil may contain more than your desired dose, making it easy to take too much.

Likewise, if your goal is to use a high-strength of CBD, buying a low-potency CBD oil (300 mg or less) doesn’t make much sense because you’ll end up having to use a quarter of the bottle for every dose.

Here are some general recommendations for what potency CBD oil to use based on your target dose:


  • 5 mg CBD dose — 250 mg CBD oil or lower
  • 10 mg CBD dose — 250 mg CBD oil or lower
  • 15 mg CBD dose — 250 – 500 mg CBD oil
  • 20 mg CBD dose — 250 – 500 mg CBD oil
  • 25 mg CBD dose — 500 – 1000 mg CBD oil
  • 30 mg CBD dose — 500 – 1000 mg CBD oil
  • 35 mg CBD dose — 500 – 1000 mg CBD oil
  • 40 mg CBD dose — 500 – 1000 mg CBD oil
  • 45 mg CBD dose — 500 – 1000 mg CBD oil
  • 50 mg CBD dose — 1000 mg CBD oil or higher
  • 55 mg CBD dose — 1000 mg CBD oil or higher
  • 60 mg CBD dose or more — 1000 mg CBD oil or higher



Key Takeaways: How Much CBD Should I Use?

CBD affects everybody differently, so it’s best to start with a low dose when using Nature Science CBD oil for the first time and increase gradually every day.

The most common dosage range for CBD products is 20 – 40 mg per dose. Some people take one dose per day, others take two or even three doses in a single day.

The potency of the CBD oil, capsules, or other CBD products you’re using is very important. You’ll need a much smaller dose of a high-potency CBD oil compared to a low potency CBD oil.
