General Daily Guidelines for CBD Dosage (Supported By 18 Studies)

There’s an incredible amount of confusion when it comes to finding the right CBD dosage. One of the first things you should determine when learning how to use CBD oil for the first time, however, is exactly how much of this healing substance you should ingest for your specific condition or ailment.

The problem is that there isn’t a clear answer when it comes to the right CBD oil dosage for medical conditions. There isn’t a single reliable CBD dosage chart out there that we’ve found, so we put together our own.

Part of the issue is that nobody reacts to CBD the same way. Different conditions likewise require different cannabidiol dosages⁠—the right CBD dosage for pain is very different than the proper CBD oil dosage for anxiety, for instance.

For seniors and others looking to try CBD for the first time, it’s essential to get an expert’s view on the subject.


The Current State of CBD Science

Here at Best Dosage, we’ve conducted vast amounts of research on CBD to try to bring sense to it all. We’ve looked at what major CBD brands have to say, and we’ve consulted with CBD oil users to get firsthand information on proper dosage guidelines. Lastly, we’ve gleaned insights from our own use of CBD products.

If you’re new to CBD, keep in mind that the staff at Best Dosage are not medical professionals, and none of the information on our website should be construed as medical advice.

What’s presented below is simply an honest opinion based on original research and hands-on experience with CBD products. You should always seek advice from your doctor with regard to your specific health condition.

It’s our hope that this guide will send you in the right direction and help you make the best decisions for your own CBD dosage.

We’re going to start with some general information, then we’ll jump in further with information on specific ailments, and lastly, we’ll get into proper CBD oil dosage for the different categories of products that are out there.


General Guidelines For CBD Dosage

The following can only be viewed as general guidelines for CBD dosage since there is no scientific consensus on the proper amount of CBD you should use. Remember, our bodies vary drastically in weight, diet, metabolism, genetics, and environment, and each of these factors plays a role when determining CBD dosage.

Just like there isn’t a “one-size-fits-all” diet, there also isn’t a single CBD dosage that’s perfect for everyone. Part of integrating CBD into your lifestyle is coming to terms with the fact that there will be some trial and error while gauging your proper dosage. A universal dosage for CBD or any natural supplement isn’t realistic.

That being said, we have found that there is a very broad rubric out there that is backed up with very real, scientific sources. Here’s a basic overview of how much CBD science says you might want to take,

There are a few points we should mention for new CBD users. First, we can’t verify the right CBD dosage for certain severe medical conditions. For instance, we don’t have enough personal knowledge about the right CBD dosage for epilepsy or schizophrenia to make an expert assessment.

Also, some of the above dosages seem a little low to us, like the General Health and Chronic Pain categories, while others seem a little high, like the Sleep Disorders recommendation. Keep in mind what we’ve prepared is a very general guideline even if it is backed by legitimate studies.

One last thing before we move on to specific dosage suggestions: If you’re new to CBD, always use the “start low and go slow” method.

You should start with a relatively small amount of CBD at a consistent pace and increase it slowly until you reach the point where you feel your treatment is working. Give it time! It could take days, weeks, or even months of patience and testing to fully determine how well CBD works for your body and your ailment.

Important Terms:

– Microdose. Taking a very low dose and increasing in small increments.

– MG count. The number of milligrams (mg) in a particular product/dose.

– Vape/vaping. Using a vaporizer to inhale CBD.


CBD Dosage For Inflammation

Turning to CBD for help with inflammation is very common. Whether you work in a physically-intensive profession, are an athlete, or simply suffer from inflammation of any kind, CBD might be the answer. It’s natural to struggle to find ways to get your inflammation under control, but cannabidiol has unique properties that might make it highly useful for inflammation and oxidative stress.

CBD dosage for inflammation tends to be a little higher than the dosage that’s recommended for some other ailments, but don’t be scared off; you’ll find the sweet spot for your body’s needs in due time.

Here is some information on how to use CBD oil to help with inflammation:

– CBD dosage for inflammation typically ranges between 50mg and 150mg per day

– Starting with 20mg per day is common, often split into 2-3 doses throughout the day

– It’s good to start with CBD oil drops since it’s easy to microdose with these products,

– Most people end up taking capsules as well due to the high CBD concentration

Seniors and others often use CBD as a replacement for ibuprofen.

While it doesn’t work for everybody, most people who try CBD report that they find relief from inflammation. For some, beneficial effects occur within just a few days, but for others, it can take weeks or more to feel an effect and find the right CBD oil dosage.

Some CBD products designed to help with inflammation and oxidative stress include turmeric in their formulas since this substance is known to be a natural inflammation-reliever.

One such product is the Sunday Scaries CBD oil and gummy line. It’s geared more toward athletes but is a great option for getting your CBD dosage for inflammation.

Since this is your first time using CBD, make sure to check out other resources as well, such as this incredible inflammation dosage guide from the world-renowned cannabis advocacy non-profit organization, Project CBD. 


CBD Oil Dosage For Anxiety

Anxiety is yet another condition for which a growing number of people are turning to CBD for treatment. Whether your psychiatric condition is mild or severe, finding the right CBD oil dosage for anxiety will go a long way toward keeping it under control.

Anxiety is one condition in which a little CBD goes a long way, yet almost everyone reports that cannabidiol does indeed help for anxiety.

Here is some more information on how to use CBD oil to help with anxiety:

– As little as 5mg per day can help, but typical CBD oil dosage for anxiety is closer to the 20-25mg-per-day range. For more severe anxiety, 50-60mg per day is also common

– It’s best to start very low, between 2-5mg per day, and split that up throughout the day

– For more severe anxiety, it is not uncommon to use a CBD tincture or capsule in the morning and then supplement it by vaping CBD intermittently during the day

– Vaping is a very popular method for getting your CBD oil dosage for anxiety since it has an almost instantaneous effect

– In fact, those who vape CBD have reported that this cannabinoid can slow down or stop anxiety attacks pretty much right after taking a few puffs

– Often used to replace Xanax or similar medications

The number of people who are diagnosed with anxiety (or self-diagnosed) has skyrocketed in recent years. There are 40 million adults in America suffering from anxiety, which is an astonishing number.

Although only 36.9% of them receive treatment, that’s still money in the bank for pharmaceutical companies. At least, it has been until CBD came along.

Treating anxiety with CBD might be the fastest-growing segment of the entire CBD industry. Vaping is a great way to use CBD for anxiety since vapor has no smell and generally tastes better than CBD oil itself.

Social CBD is a brand that seems to target anxiety sufferers specifically, producing a disposable CBD vape pen called Relax.

However you decide to get your CBD oil dosage for anxiety, chances are your new natural health routine will have an impact. New CBD users should avoid going overboard with consuming this substance for anxiety, and always consult with your doctor before using cannabidiol if you’re already on benzodiazepines or other anxiolytic medications.

After consulting with 1013 CBD studies, researchers concluded that this cannabinoid is good for pretty much everything, so don’t be afraid to experiment with this new, natural tool for curbing your anxiety.


CBD Dosage For Pain

This usage of CBD is probably the trickiest. For one, pain is a subjective sensation. One person’s pain tolerance may not be the same as another individual’s, so while a certain dosage could work well for you, it might be woefully inadequate for handling the needs of your neighbor.

There are some generally-known facts about CBD dosage for pain which might help. People use CBD for all sorts of conditions that cause them pain, such as fibromyalgia, arthritis, neuropathy, and others. Here is some more information on how to use CBD oil to help with pain relief:

  • CBD dosage for pain varies widely
  • For some, as little as 20mg per day might be enough, but for others, 200mg per day is what they absolutely need just to get by
  • It’s still best to start low and slow
  • Depending on how much CBD you have and what kind, starting out somewhere between 10-20mg per day is normal, and you can quickly move higher if you don’t see results
  • CBD has been known to “untighten” muscles that have been locked in place for years
  • In addition to physical pain relief, CBD has generally been known to reduce stress and anxiety, which itself goes a long way toward pain relief
  • Often used to replace ibuprofen or even Vicodin

Getting the right CBD dosage for pain is harder than it is for some of the other ailments this cannabis component is used for. If you live in a state where THC is legal, consider trying a product that has a combination of CBD and THC since this approach might work better for your needs.

Regardless, CBD alone can be a gamechanger for those looking to get off pain medications or at least reduce their reliance on them.

If you’re enduring chronic pain and you want to try CBD for the first time, it’s worth trying CBD offerings from a few different brands to understand what works best for your body.

We’ve heard people raving about the brand Hemplucid, in particular, for being able to reduce pain. If that brand’s products don’t work for you, don’t give up, and try another offering we’ve reviewed here at Best Dosage.

Finding the right brand and the ideal CBD dosage for pain is a journey, but the payoff is huge. Remember that you can rely on online dosage guides throughout the process to make sure you stay on track with your CBD needs.


CBD Dosage For Rheumatoid Arthritis

Finding relief from rheumatoid arthritis can closely match the journey to relief from inflammation or pain. While there is some crossover, the ideal CBD dosage for rheumatoid arthritis isn’t exactly the same as it is for other conditions.

You can experience inflammation as a temporary side effect of physical labor or an injury, but the type of inflammation involved in rheumatoid arthritis can flare up for no reason at all.

More and more people are turning to CBD as a possible answer to their suffering. According to Consumer Reports, you shouldn’t expect miracles from your new CBD regimen, but nonetheless, thousands of people around the world have experienced relief from arthritis with CBD that’s nothing short of miraculous.

Here is some more information on how to use CBD oil to help with rheumatoid arthritis:

  • A combination of a CBD tincture and a CBD topical is very common and effective
  • Due to this synergy, correct CBD dosage for rheumatoid arthritis is harder to gauge
  • Generally, the range will be from 20mg to 120mg a day with additional CBD transmitted transdermally via a salve or cream
  • Starting with just a few drops of CBD oil taken sublingually under the tongue is a good way to go, and up your dosage as needed
  • Massaging a CBD salve or cream into your skin where you have joint pain can go a long way
  • Often used to replace Advil

The big difference between using CBD for inflammation and using it for rheumatoid arthritis is that the CBD dosage for RA practically demands a topical.

Inflammation can be helped with a topical too, but for this type of arthritis, you really should make topical administration of CBD part of your routine. Especially for new users of cannabidiol, trying multiple administration methods at once is a great way to get a grasp of how this non-intoxicating Cannabis sativa extract can help you.

There are quite a few incredible CBD salves and lotions out there, and we particularly appreciate the hemp salve offered by Endoca for its high CBD content. Test out all the possible combinations of oils, tinctures, and CBD topicals until you determine what works best for you personally.

Your safety should be your first priority as you select the right CBD product for arthritis, so remember to follow Consumer Reports’ 6 CBD Buying Guidelines as you proceed.


CBD Oil Dosage For Everything Else

Note: If you’re curious about the right CBD dosage for sleep, online guides can be very instructive.

While the above conditions are the most common applications of CBD treatments, there is a lot of other ways that CBD appears to be medically beneficial as well. We won’t get too heavily the right CBD oil dosage for cancer since we don’t know enough about this subject and it’s best to refrain from speculation.

The same goes for the best CBD oil dosage for autism, although there is a recent study that delivered incredibly promising results. Still, there are a few other categories that we can lump together in this section to provide some quick takes. Here’s some information on how to use CBD oil to help depression, ADHD, and even your pets:


CBD Dosage For Depression

The right CBD dosage for depression is comparable to the right dose for anxiety. Typically, you can start with as little as 5-10mg of CBD per day, and if you don’t note the desired effects, you can microdose up to get to the threshold where a real difference is felt.

Remember to continue consulting CBD dosage guides as you harmonize your daily CBD routine with your body’s needs.

It appears that full-spectrum CBD products work better for depression compared to isolate-only offerings. While you should never stop taking your existing depression medication without advice from your doctor or mental health professional, we know that many people have been using CBD to end their reliance on SSRIs and other pharmaceutical antidepressants.


CBD Dosage for ADHD

Many parents want to know the proper CBD dosage for children who suffer from ADHD, and we’re very cautious about providing advice about how to administer CBD to minors. In this section, we’re only addressing adults who want to replace or supplement common ADHD medications such as Adderall or Ritalin with CBD.

A little goes a long way when treating ADHD with CBD, and we’ve heard of 10mg, or even 5mg, being enough. However, it isn’t unusual for a CBD dosage for ADHD to be closer to the 20-25mg range.

Once you’ve found the right brand to cater to your needs, you can microdose with CBD to your heart’s content until you start to regain the focus you need to tackle the day effectively.


CBD Dosage For Dogs

Yes, even our furry friends benefit from CBD. In fact, a growing chorus of pet owners has eschewed traditional medications for animal anxiety and pain and order CBD instead. You’ll still need to know how much CBD to use even though you’re giving it to your pet instead of taking it yourself, so keep those CBD dosage guides handy.

The right CBD dosage for dogs is highly dependent on how big the dog is, so always keep that in mind before you give cannabidiol to your pooch.

We like that CBDfx makes a line of CBD pet products that includes various strengths for small, medium, and large breeds. As per CBDfx’s recommendations, CBD dosage for dogs should be 1mg of CBD for every 4lbs of your dog’s body weight.


Does CBD Bioavailability Matter?

Now that we’ve outlined the proper CBD dosage for each ailment above, we’re going to move on by breaking it all down by consumption method. After all, the way you choose to take CBD also plays a role in determining the proper CBD oil dosage for your needs.

First, you’re going to need to know a little about CBD bioavailability. This is a topic that can get kind of complicated, but we’re going to keep things simple for you and focus on pragmatic results.

To become an expert on CBD bioavailability, you should start by learning that every milligram of CBD you put into your body needs to, at some point, get to your bloodstream to have an effect.

The route your body takes to deliver CBD into your bloodstream has a significant impact on the intensity and duration of the effects of this cannabinoid as well.

For instance, taking CBD oil drops sublingually (by placing them under your tongue) brings them into nearly direct contact with your bloodstream.

This factor increases the bioavailability of CBD you ingest using this method, which is a measurement of the total percentage of CBD that is absorbed by your body before it is excreted. Studies have shown that consuming cannabidiol in this way gives you a CBD bioavailability of somewhere between 12% and 35%.

Compare this absorption rate to that of a CBD gummy, which has a bioavailability of around 6%. Sounds rather clear-cut, right? Just use the administration method that gets more CBD into your bloodstream. In reality, however, it isn’t that simple.

Start by considering the different ways that consuming CBD will affect: 1. How quickly your body starts to feel the effects of the CBD, and 2. How long your CBD dosage will actually last.

Although CBD edibles may seem like a waste due to their comparatively low bioavailability, other people appreciate how long CBD actually stays in their bodies when they consume this substance orally.

You should also consider the ease of use of various CBD products. Sometimes it’s a lot easier to grab an edible or a CBD vape pen before you head out for the day than it is to figure out how to pack a whole bottle of CBD tincture and find a comfortable place to take your CBD oil dosage the proper way.

CBD bioavailability is a hot topic, and there are plenty of commentators who rail against one method or another, especially on Reddit. What matters in the end, however, is how CBD fits into your lifestyle and how it might make you feel better. Sure, the availability of CBD in your body does matter, but not nearly to the extent that some voices in the cannabidiol community might make you think. Always choose what works for you and your body while remembering that everyone is different.

Now, let’s get into some common questions regarding CBD oil dosage via the different methods of consumption. Instead of trusting the advice of anonymous message board users, always rely on Best Dosage whenever you need to learn more about the top ways to take CBD.


How Many Drops Of CBD Oil Should I Take?

Many people first experience CBD in the form of a tincture. Taking CBD oil sublingually by placing drops under your tongue for 30 seconds or longer is often cited as the most effective way to use this cannabinoid.

However, you may still be wondering: How many drops of CBD oil should I take? To understand the proper CBD oil dosage for you, you’ll first need to know how much CBD is in each drop.

This will vary by brand and also depends on the strength level you choose. Remember that sometimes it’s best to learn how much CBD you need directly from the company that makes it.

One example is the CBD oil dosage for NuLeaf Naturals. They list the serving size for their  725mg bottle of full-spectrum CBD oil as ½ of a dropper or 10-12 drops.

As each drop contains 2.4mg of CBD, that would work out to 24-29mg of CBD. If you’re new to CBD, this could be entirely too much. It’s also important to keep in mind that some conditions require more CBD than others.

We always recommend starting with just a few drops and then moving up after a few days to a week. Your body needs time to adjust to the CBD itself, and there will be some trial and error until you find the proper CBD dosage for your needs.

The good thing about CBD oil is that you can increase or decrease your dosage with single drops, which is the best way to microdose. CBD doesn’t appear to have any serious side effects, so feel free to use however much you want.

Regarding CBD bioavailability, taking CBD oil sublingually typically takes between 15 minutes and an hour to feel. You should feel the effects for a nice amount of time⁠—somewhere between 4 and 6 hours is normal.


How Much CBD Should I Vape?

One big advantage that vaping has over other CBD administration methods is the almost immediate effect provided when you inhale a cloud of CBD vapor. While the CBD availability of vaping is really high, it also goes away faster.

A few hours is probably the most you’ll get out of vaping CBD, so this might not be the right way to use CBD for sleep. Since you’ll be dosing more often, it makes it even more important to answer the question: How much CBD should I vape?

Like strength levels with CBD tinctures, determining the proper CBD dosage for your vape pen will also depend on how many milligrams of CBD it includes.

The nice thing about vaping when compared to other methods is that you can play it by ear a bit. Since vaporized CBD hits your bloodstream instantly, you can simply take a few puffs, see how you feel, and inhale more as needed.

Higher-milligram options like a Social CBD 250mg vape pen will require less vaping as you’ll get more with each puff, but there also isn’t ever really concern about your CBD dosage being too high with vapor.

You’ll know how the CBD you vape is affecting you based almost instantaneous sensations, so don’t be too concerned about having an exact answer to how much CBD should I vape.

Is vaping CBD safe? There’s no indication that any of the recent vape injuries were caused by CBD, and this administration method is safe when CBD vape products are formulated correctly. If you want to read up further on vaping CBD, be sure to check out our Guide to CBD Oil Vape Pens and CBD Oil Vape Juice.


How Many CBD Edibles Should I Eat?

Really, the question shouldn’t be how many edibles should I eat, but how many milligrams of CBD you should ingest. New CBD users need to pay even more attention to the amount of CBD the edibles they use contain.

We often see this question posed the wrong way, so this is a good opportunity to make a clear distinction: How many CBD gummies you should take isn’t a valid question if you don’t know how many milligrams of CBD are in each gummy.

Your CBD dosage for edibles is going to rely significantly on the condition you are trying to alleviate. Unlike CBD tinctures or or vape juice, using CBD edibles is a really straightforward dosing proposition since there will likely be a set amount of CBD contained in each edible product you consume.

The CBD bioavailability of edibles is on the low end of the spectrum, however, which means it could easily take more than two hours to feel the effects of your CBD edible. Due to this delayed-release effect, it’s important to start low and work your way up slowly. That’s the rule for CBD in general but even more so with edibles.

On the plus side, users report that edibles last them a great deal longer than other CBD product types: CBD-infused edibles can stay in your system as long as 9 hours with 6-8 hours being typical. For CBD users who don’t want to deal with the annoyance of dosing throughout the day, higher-milligram edibles like 25mg Hemplucid CBD gummies are a great option.


How Much CBD Topical Is Enough?

If you’re using a CBD topical, chances are you’re using it either for pain, inflammation, or a skin condition. As a standalone, a CBD topical can work wonders if you’re dealing with a chronic skin problem that isn’t taking to treatment or if you simply want to find a more natural solution to your issue.

Determining CBD dosage for a topical essentially consists of putting a dab of lotion or salve on the affected area and watching how it reacts. Usually, you’ll know within a few days or a week if it’s doing the job since the CBD bioavailability through your skin is really high.

If your CBD topical doesn’t yield the desired results, try dosing more throughout the day, or use a different brand. If you’re dealing with localized pain or inflammation, often a combination of a high-quality CBD capsule along with a CBD topical will work wonders.

Expect a CBD capsule to take about an hour to fully absorb into your bloodstream, and then go ahead and add your topical into the mix. We like 25mg CBDPure Softgels since they go down easy without any aftertaste, and this brand backs up its products with a 90-day money-back guarantee.

Remember that CBD topicals aren’t very effective for widespread conditions like seizures. Supplement with an oral CBD product if you want to make sure all your bases are covered.


Final Words On CBD Dosage

We just threw a whole lot of information at you, but we did it in the hope that it would answer a lot of the questions you probably had about CBD dosage. There are a few things we want to make sure to leave you with that are important to keep in mind.

First, we didn’t completely address the full-spectrum versus CBD isolate debate. To make a very long story short, full-spectrum CBD-rich hemp oil has been shown to be more effective for most people due to a phenomenon known as the “entourage effect.”

The various cannabinoids and terpenes present in cannabis all work together to provide a final effect that is more than the sum of their parts. Typically, there will usually be trace amounts of THC in full-spectrum CBD oil products, but not always.

Being worried about failing a drug test is a common reason people give for choosing a pure CBD isolate product, which only has CBD, over something full-spectrum. Recently, a new form of CBD oil has been produced, broad-spectrum, that offers the benefits of full-spectrum while eliminating all but undetectable levels of THC.

Sometimes CBD isolate or broad-spectrum CBD just works better for certain people. We’ve encountered CBD users that were dealing with severe pain who insisted that a CBD dosage in isolate form works far better. It’s hard to argue with first-hand accounts like these despite the studies that say the opposite.

Even with all the suggestions we’ve given you based on our own research and experience (again, these are not to be misconstrued as medical opinions and we make no such claim), every single person is different. Whether it’s the right CBD dosage, the right product category for CBD bioavailability, or simply the right brand, every factor in the purchasing process plays a role.

CBD seems to be an unusually fickle cannabinoid, and one person’s panacea will be another person’s “snake oil.” If you’re determined to find a solution for what ails you with CBD, you’ll need to have some patience and deal with a little (or a lot) of trial and error.

Along the way, we’ll be here to help you in any way we can. Feel free to comment below with your feedback or any questions you might have. It’s been a pleasure taking you on a CBD dosage journey, and thanks for coming along for the ride. Here’s to making your own personal CBD success story a reality!
