How many milligrams of CBD should I take

Okay, so we’re going to go ahead and apologize in advance if that title was a little bit, erm… ‘misleading.’ The fact is, there is no exact “right” amount of CBD to take in terms of how many milligrams you should be dosing on a daily basis.

Considering the endless amount of variables that are at play, it would be naive to dish out some random number (say 25 mg oral CBD taken twice daily), and say that that amount will be effective for everyone.

For instance, here’s just a small list of some of the things that might affect how many mg of CBD it will take for you personally to start noticing therapeutic effects:

  • How old are you?
  • How much do you weigh?
  • What is your normal diet?
  • What symptoms are you trying to treat?
  • How are you consuming the CBD (vaping, smoking, oil, edible..)?
  • Is it a full-spectrum CBD or a CBD isolate?
  • Is this your first time taking CBD?
  • Are you a previous cannabis user?
  •  Do you already have a tolerance built up?

And this is just an ‘off-the-top-of-my-head’ list to boot – there are many, many other things that a serious doctor (which we most certainly are not) would probably take into consideration before issuing a dosage recommendation.

| But don’t let this discourage you; at the end of the day, the majority of CBD users will take a daily dose between 10 and 75 mg, with fairly effective results.

And of course, given the fact that CBD has been declared by the World Health Organization as “well tolerated with a good safety profile,” and having “no evidence of public health-related problems,” there is apparently very little risk in terms of adverse side effects if you take a dose that’s too large.

In this article, we will do our very best to set you off on the right path to finding an effect CBD dose that works for you and your condition. In other words, don’t let the question of ‘how much CBD oil do I take’ be an overwhelming or overly- complicated one. As you’ll see, it’s not all that difficult.

How Much CBD You Take Depends on What TYPE You’re Taking

Generally speaking, there are two main types of CBD oils out there: full-spectrum and CBD isolates.

Full-spectrum CBD oils are tinctures that incorporate the entirety of the raw plant material that the CBD is sourced from. In other words, in addition to containing the active CBD compound, a good full-spectrum oil will have other phytocannabinoids (such as CBG, CBC, CBN, etc), phytonutrients, terpenes, flavonoids, and omega acids included from the raw material – a veritable smorgasbord of “cannabis goodness.”

CBD isolate, on the other hand, is exactly what it sounds like it is: the active CBD compound all by itself, with no additional compounds. Which one is “better,” you might be wondering?

Well, several studies have surfaced in recent years showing that full-spectrum tinctures are generally more effective due to the “entourage effect” of cannabinoids – in other words, that CBD seems to be more potent and therapeutically effective when working alongside other natural compounds from the plant.

That being said, CBD isolates definitely have their place in the world of medicinal cannabis, and many people swear by them. If you’re just starting out using CBD oil and wondering how much to take, it’s typically recommended that you start with a good full-spectrum product rather than an isolate.

How Many Milligrams of CBD to Take

Once you’ve decided on a good, high-quality full-spectrum CBD oil, it’s then time to decide how many mg to take. This is where things can get a little bit frustrating, as cannabis extracts can indeed be a little finicky in terms of finding the perfect dose.

If you have access to a physician or other form of health professional with knowledge of medical cannabis, by all means do not be afraid to ask them – their knowledge is more valuable than you might imagine.

In any regard, almost any bottle of CBD oil you get will come with a dropper, as well as general guidelines for dosing. For reference, a standard 300 mg bottle of PureKana’s Premium CBD Oil contains 7.5 mg of CBD in a single “dose” (a dose being 15 drops of oil).

FAST FACT | 20 drops of CBD oil = 1 mL. Thus, a standard 30 mL bottle containing 600 mg of CBD would contain 1 mg of CBD per single drop.

Generally speaking, if you are just starting out with CBD oil you’ll want to start out with a small dose and work your way up from there. This is because taking an excessive amount could actually be less effective from a therapeutic standpoint, rather than taking just a moderate or small dose.

By “small dose,” we’re talking between 1 mg and 2 mg of CBD to start out with. Again, using the PureKana oil as a reference, instead of taking a full 15 drops of oil (which would equal 7.5 mg), you would want to start off with about two to four drops (each drop contains 0.5 mg of CBD, so two drops would equal 1 mg, and four drops would equal 2 mg).

Once you’ve taken this initial dose, wait several hours before taking another dose, and try and listen to your body as closely as possible for potential effects, as the “onset” of CBD is notoriously subtle.

Also, it’s worth pointing out that it’s better to take multiple low doses of CBD a few times a day, rather than a single large dose.

But What if You Don’t Feel Anything?

Truth be told, you’ll be unlikely to notice much (if any) effects from that initial 1 or 2 mg dose. However, you’ll want to stick with it for several days (3-5 days) before upping your milligram intake.

If you start upping your dose right away, you’ll have no idea if the compounds are working with your body’s endocannabinoid system or not, and you may run the risk of “overloading” your receptors before they even have a chance to start working. It takes patience finding the right dose, but trust us — it’ll be well worth it in the end.

If after several days you find that you still have not noticed any effects from the CBD, then try upping your dose – but only in small increments.

For example try a 5 mg dose taken two or three times per day (morning, afternoon, evening) if you don’t get anything from the 1-2 mg dose. Also, as we mentioned earlier it’s important to spread out your CBD intake over the course of the day in a few small doses, rather than dumping one big dose down your throat in the morning and waiting for some “miracle effect” to kick in.

If you don’t notice anything from the 5 mg dose, then up it to 7.5 mg, then 10 mg, then 12.5 mg, etc — until you start noticing positive effects.

Also, it’s key to spread those doses out over the course of the day; even if you get up to 15 or 20 mg without noticing any effects, keep administering three doses a day (i.e. 20 mg in the morning, 20 mg in the afternoon, 20 mg in the evening). This not only gives your body time to adjust to the amount of cannabinoid receptors it needs to ‘activate,’ but it also allows you to keep a more keen eye on whether any effects are taking place or not.

It’s worth mentioning, however, that you may not need to take two (or three) doses per day – many people find that just a single morning dose will offer plenty of therapy to get them through the day. (Or if you’re taking CBD for sleep issues, that a single evening dose is all that’s needed to get you through the night).

Figuring out how many mg of CBD to take is a process that requires time, effort, and a keep ability to listen to your body — don’t get frustrated, don’t overdo it, and most importantly of all, be patient.

Other Considerations on How Many Mg CBD Oil to Take

One thing about CBD that’s important to understand is that it affects everyone differently. This has to do with the fact that each and every one of us has a unique endocannabinoid system, and a unique makeup of CB-1 and CB-2 receptors throughout our bodies. While one person may experience extraordinary effects for their chronic pain using a 50 mg twice-a-day dose, another person with the same exact symptoms may experience far less.

And of course, there unfortunately are the people who won’t experience any effects at all – no matter how much CBD oil they take. This could be down to the fact that they have no active cannabinoid receptors in the afflicted system or body part that they’re trying to treat, or that there is some sort of dysfunction with the receptors that are there, that’s not allowing them to interact with the CBD compound. (This is why you can be reading customer reviews from a high-quality brand, and come across some person that says, “this product is terrible — doesn’t do anything AT ALL!”

At the end of the day, there is still much to be learned in terms of proper dosing for CBD. This article is just a simple, basic “jumping off point” that will hopefully help get you going in the right direction. (And again, we must reiterate the fact that we are NOT doctors or healthcare professionals, and as such, nothing herein should be taken as clinical advice or medical recommendation).

Lastly, we want to mention the fact that it’s common for people to take doses of CBD much larger than those that we have been mentioning throughout the article. For instance, while we said earlier that “most” people find decent therapy with doses between 10 and 75 mg (taken once, twice, or three times daily), there are plenty of people out there who self-treat with doses well over 100 mg (taken multiple times a day). In fact, many epilepsy patients will consume well over 1 gram (1,000 mg) of CBD in a single day, with no adverse side effects.

CBD Oil Mg Conversion Chart

In order to know the dosing/serving size of any bottle of CBD oil, we must know two things:

  1. Total CBD content that’s in the bottle (mg)
  2. Size of the bottle (mL)

Since there are 20 drops in 1 mL of oil, you can multiply the size of the bottle by 20 in order to get the total number of drops in the whole bottle. For example, a 30 mL bottle would contain 600 total drops (30 x 20 = 600).

| In order to figure out the amount of CBD you’re getting in a single drop, divide the total mg of CBD in the bottle by the total # of drops in the bottle.

For example, say you have a 10 mL bottle of CBD oil that contains 300 mg total CBD. We know that there are 200 total drops in the bottle (10 mL x 20 drops in a single mL = 200 drops total). Then, we divide 300 mg by 200 drops to get 1.5 mg of CBD per single drop.


5 mL 100 drops
10 mL 200 drops
15 mL 300 drops
20 mL 400 drops
30 mL  600 drops

Final Thoughts: How Many Milligrams of CBD Should I Take?

Another thing that most new CBD users don’t realize is that cannabinoids are compounds with biphasic effects. This means that rather than producing effects in a predictable, linear path (i.e. the more CBD you take the stronger the results), low and high doses of the compound actually have opposite effects.

In other words, if you’re taking CBD to help you sleep, you could totally exacerbate your symptoms (i.e. make them worse) if you take too small of a dose. This is due to the fact that small doses of CBD are known to have stimulating effects, while large doses of CBD are known to have sedative effects (at least according to an article published by Project CBD).

We have heard countless people complain that their CBD oil made things “worse than they were before,” and we don’t doubt them at all. However, 99% of the time it just comes down to a simple dosing mistake. Like we said, listen to your body, have patience, and don’t overdo it.

CBD is a wonderful, safe, therapeutic, 100% natural plant compound that we genuinely hope you can experience the positive effects of. And after all this if you’re still wondering how many mg to take, shoot us a message or comment below and we’ll help you out.

    Start with 7 to 8 drops

    If you are not sure of how much you must take, and you are an adult of average weight, start with 7 to 8 drops daily, and then see what works out for you. CBD is different for different people, and there are many factors in your body that would affect the decision. So just try.

      Before I say anything, I think i must know how old are you and how much do you weigh. For example for a 40 year old person, who weighs around 60 Kgs, about 3-4 drops of this would be sufficient.
