What’s the Best CBD Dosage?

Newcomers to the world of CBD might be confused about how much to take. After all, options range from 100mg per bottle to 5000mg per bottle – how can there be so much variation? CBD dosage is relatively straightforward, so we will break it down in this article.

First off, it’s essential to recognize that CBD is said to be generally well-tolerated by the World Health Organization, which means most people do not have an adverse reaction. Even extremely high doses of over 1000mg per day are well-tolerated in most people.

That said, the vast majority of users require way less than this. A smaller dose is better for your tolerance, and it’s kinder to your wallet. So, how much CBD should you take?

How Much CBD to Take

The amount of CBD you need varies between individuals. It can be tricky to determine your optimum dose if you have never used CBD before.


A range of factors will impact your required dosage; we cover them in more detail later.

Generally, people take 20mg or more of CBD each day. Many products, like capsules and gummies, come with a pre-measured dose of CBD. 25mg per capsule/gummy is pretty much standard, but this doesn’t mean it’s the best dose for you.

With oils, the matter is more complicated. First, you need to know how much CBD is contained per dropper.

How to Calculate Dosage

Sometimes, a product will state how much CBD it contains per serving on the label. At other times, you’ll need to do a bit of math.

One drop of CBD oil is usually about 0.05 milliliters (ml) – this is not one full dropper but a single drop of oil. In a 10ml bottle, there are 200 drops.

Let’s take the PureKana 1000mg CBD oil as an example. Our 30ml bottles contain 600 drops. That’s roughly 1.7mg of CBD per drop. In a whole serving of 15 drops, there’s roughly 25mg.

Factors That May Influence Dosage

An extensive range of factors can influence the dosage you need. This includes:

  • The reason for taking CBD
  • Height and weight
  • Metabolism
  • Genetics
  • General health

Every individual reacts differently to CBD, so determining a dose is quite tricky. As a general rule of thumb, it’s best to start with a lower dose of CBD (15-25mg) and increase it every few weeks until you experience the desired effects.

What’s a Safe Dosage?

Most human studies use dosages between 20mg and 1500mg per day on participants. It’s usually well-tolerated even in these high doses.

No specific studies have analyzed the long-term effects of high CBD doses. Furthermore, there are no thorough reviews on the optimal dosage for everyday users.

That said, the literature indicates that a safe dosage of CBD can extend beyond 1000mg per day. Still, taking this much every day is not necessarily a good idea; for a start, doing so could get incredibly expensive.

Secondly, taking enormous amounts of cannabidiol needlessly could cause your body to build a tolerance fairly quickly, nullifying the effects of the CBD.

Just because the dosage is considered “safe” by medical studies does not mean it’s a good idea to use it.

What Happens if You Take Too Much CBD?

There are a few side effects of CBD, which we discuss in more detail below. In general, taking ‘too much’ CBD will lead to the appearance of these side effects, which are usually minor and cease quickly when you stop taking the tincture.


The research noted above suggests that even those taking over 1500mg a day consistently tend to tolerate CBD well. However, there are concerns about CBD’s interaction with certain medications.

CBD can interact with certain liver enzymes that affect the metabolization of some medications. A simple rule of thumb is that if you’re taking medication that prevents you from eating grapefruit, you should also avoid CBD. Grapefruit and CBD interact similarly with liver enzymes.

If you have any pre-existing conditions and are using medication, it’s vital to discuss any new supplements with your physician. They will best be able to advise you about the ideal CBD dosage and if it’s suitable for you to take.

What Are the Side Effects?

For most people, CBD’s side effects are minor. The list includes:

  • Fatigue and grogginess
  • Diarrhea
  • Changes in appetite
  • Nausea

These are all very minor, and some people don’t experience them at all. When using CBD for the first time, use a small amount and keep an eye out for these side effects. If you experience drowsiness, avoid operating heavy machinery.

If you experience intense side effects, stop using CBD immediately and contact your doctor. In most cases, side effects can be abated by reducing the dose.

It’s worth noting that side effects and unpleasant experiences are more likely if you use CBD from a poor-quality brand. These items are more likely to contain toxins, heavy metals, and pesticides, triggering bad reactions.

Bottom Line

CBD is a unique experience for everyone. It can be challenging to accurately pin down the best dosage for you, a prospect that may intimate new users.

Never worry, though – finding your perfect CBD dose does not have to be a terrifying concept. Start with a low-strength CBD oil (around 1000mg is often a great place to start), and use a small amount each day. Keep a journal of how much CBD you’re using and what the effects are.

If you experience no benefits after a week or so, gradually increase the dose in small increments until you find that sweet spot.

Keep up the good work
