How to Know Which CBD Oil Strength is Best For You [BEGINNERS GUIDE]

Understanding what you need.

CBD oil strength

Deciding to use CBD oil as a natural therapy is one thing – figuring out which brand to use, what strength/concentration to use, and how much CBD to actually take is another thing altogether. Plus, with all of the products out there to choose from and their confusing mL/mg labels, it can be a nightmare trying to determine which one is best for you, or which one you should be taking for your specific condition.

In this article, we will go over how to choose the right strength CBD oil depending on the condition that you’re trying to find relief from. Thousands upon thousands of people everyday use CBD as a therapy for a range of medical conditions, but it is important to have an idea of the right concentration oil to use, in order to get the best results.

That being said, however, it is important to point out that CBD is not yet an approved substance by the FDA – in other words, it is not legally recognized as a drug or medicine. Thus, none of the information we provide here should be taken as clinical recommendation or medical advice – we’re not health professionals, and we certainly don’t claim to be. If at all possible, arrange an appointment to speak with a clinical professional about the proper use and dosing of CBD oil.

Different Strengths/Potencies of CBD Oil

Even though there are dozens of different CBD manufacturers out there to choose from, most of them will offer oils in at least two or three different potencies, or concentrations. Which concentration you choose should depend on what you’re looking to get out of the product, as well as what condition you’re aiming to find relief from.

For the purposes of this article, we will be using PureKana’s line of Premium CBD Oil Drops as a reference. PureKana has been a reliable manufacturer and one of the leaders in the CBD industry for a couple of years now, and their products typically receive excellent customer feedback.

As of right now they offer oil tinctures in three different strengths: 300 mg, 600 mg, and 1000 mg. Naturally, their 300 mg bottle is their lowest-potency option, and this is the oil that most people recommend to start out on – regardless of the condition that they’re trying to treat.

Generally speaking what ends up happening is people who use CBD oil daily as a relief from chronic conditions (i.e. chronic pain, inflammation, insomnia, depression, etc) will end up switching to the high-potency 1000 mg bottle or more. However, even if you do suffer from one of these chronic conditions, it’s still recommended that you start out with the low potency oil first, at least until you gauge how your body reacts to the CBD. It’s important to understand that because everybody’s biochemistry is different, not everyone will react the same or get the same therapeutic effects from CBD oil.

Also, starting off with the lowest potency oil lets you adequately gauge how much CBD it takes to relieve your specific condition. If you’re treating severe pain for example, and you jump right into the high-strength 1000 mg bottle, you’ll have no idea how much oil it actually took to provide relief, even if it ends up working well for you.

If you start with the low-strength option, on the other hand, you’ll be able to start off with a 1-2 mg dose, then if that doesn’t work you can increase to a 3, 4, or 5 mg dose and see what that does. If you jump straight into a heavy 15+ mg dose and receive adequate therapy, you’ll never know if a smaller dose would’ve worked just as well. This is important on two levels: A) it will save you money from not taking more CBD oil than you need, and B) it will reduce the likelihood and/or severity of developing a tolerance.


CBD Oil: 300mg, 600mg, and 1000mg Options

Like we said, once you start using CBD oil more frequently and are able to gauge how much you need to find relief or therapy, then you can jump up to the more high-potency products as needed.

Generally speaking, here is a quick rundown of each of PureKana’s three different CBD oil concentrations, and what the majority of people uses them for:

Low potency CBD oil (300 mg)

A lot of people have used the 300 mg oil for conditions like mild to moderate anxiety and minor body aches and pains. Also, the low-potency oil is great for individuals who’ve found that they’re highly sensitive to CBD (and/or cannabis in general) – some people have a more active endocannabinoid system than do others, so they will naturally not require as strong of an oil.

The low-strength 300 mg is also an excellent option to take as a daily supplement, and many people take a single daily dose of it for increased immune health, increased bodily balance, and general disease prevention.

A single serving of the 300 mg (30 mL) bottle is equivalent to 15 drops of oil, which translates to a 7.5 mg dose of CBD. A lot of people won’t even use a full dose though, as they’re able to find relief with as little as 5-7 drops of oil, which translates to about a 3.5 mg dose.

Mid potency CBD oil (600 mg)

The 600 mg oil is a good step-up option for people who find that they’re having to take large (and/or multiple) doses of the 300 mg in order to get effective results. In general, a lot of people use it for more moderate cases of anxiety, pain, inflammation, and digestive issues. A single dose is still the same 15 drops of oil, but instead of containing 7.5 mg of CBD, the 600 mg bottle contains 15 mg per dose.

High potency CBD oil (1000 mg)

Of course, the 1000 mg CBD oil is the most high-strength option. People have used it successfully in the past to treat severe cases of insomnia, depression, anxiety/panic attacks, chronic pain, and/or as a buffer while weaning off heavy drug or alcohol addiction. It’s not recommended that first time users start out with this tincture.

Just like the 300 and 600 mg products, it comes in a 30 mL bottle, but a single 15 drop serving equates to a heavy 24 g dose of CBD – unless your condition is fairly severe, you likely won’t have use for this high-strength tincture.

Final Thoughts: Understanding Which Potency CBD Oil to Take

The main thing to consider when figuring out how to find the right strength CBD oil is to realize that everyone’s internal biochemistry is different – while your friend may be able to relieve her anxiety with just a single 3 mg dose, you may require several times that much in order to obtain the same results. Or, you may not find any relief at all. This is why it’s important to start off with the smallest possible dose, and work up from there.

Also, make sure you understand that CBD oil is not a recognized medicine, at least as of yet. Because it hasn’t been approved by the FDA, even the best CBD oils on the market have to put a label on their products saying something like “this product is not intended to diagnose, treat, cure, or prevent any disease.”

And lastly, don’t hesitate to speak with a marijuana doctor or health professional about using CBD oil. Please note,  it is not our goal for any of the information on here to come across as clinical advice or medical recommendations. If you live in a state with legalized medical marijuana, make sure you take full advantage of the resources that are available to you – getting a licensed MMJ card is easier than it has ever been before, and it could very well be one of the best decisions you’ve ever made for yourself.

    Love the 300mg

    Been using the 300MG. Honestly the 600mg was a bit strong for me. Fortunately I don’t have a serious condition and therefore it is enough. To everyone else, stay healthy and strong

  2. Merlin

    CBD will be different for everyone who takes. Be patient and take the time to figure out how your body responds to it. Doctors out there aren’t going to be able to help with anything. Unless they are a cannabis doctor that is familiar with CBD, and those are practically non-existent in most parts of the country

  3. Karl

    Really helpful article, thanks so much for sharing. I am going to start out with 5 mg and go up (or down) gradually from there. Hoping it will be effective for my back pain

  4. Glenn

    Most brands offer a range of potencies. if it’s your first time using, I’d start out with the middle-grade strength. That way you can go either way depending on the effects you feel (or don’t feel). I would recommend starting off with around a 5 mg dose then go from there

  5. Paul

    My advice after taking CBD oil for 5+ years for chronic back pain? Keep a log or journal of some kind while you figure out your doses. The effects of cannabinoids are non-linear, meaning if you take even a little more than what your body needs, the results can be counterproductive. Less is ALWAYS more when it comes to dosing CBD (and any kind of cannabis for that matter)

  6. Eva Gonzalez

    actually have used the Elixinol X-pens before and love them. 15 mg shot every time, I don’t need to use all that often so not bad for me in terms of cost effectiveness. take your time and find the right dose… good article

  7. greg v

    Always have heard you’re supposed to start out with as little as a single mg and work up from there but in my experience I usually have to almost double the recommended dose. Just my observation but I am a big guy (260+ lbs) so who knows

  8. Dylan

    The pre-dosed pens and capsules and stuff like that are great, but still prefer regular oil droppers in case you want to change up the dose on an as-needed basis. Still have found it tough to find an oil that is potent enough for me

  9. Clarissa


    Has anyone tried Floyd’s of Leadville? They were recommended by a friend but I would love a second opinion.


  10. Chaya

    In my experience the dosing “recommendations” on most brands are very much on the low side. I’ve had to at least double most recommended doses before noticing any effects. Thanks for the article

  11. Sumati SOOKDEO

    Hi now started Lazarus natural brand standard potency 225mg .15ml /15mg cbd per ml. I took a full stopper . Is that good ?… just have minor pains. Is this a good brand ?…

    1. Vivian B

      Never heard of this brand, so i would watch out. A few of them on this article are ok but it depends what you want to treat

  12. Geoff

    I have never consumed and form of Marijuana before but I have chronic back pain caused by disc and vertabrae damage, pinched nerves and muscle spasams. No doctor has given me anything that will help and physiotherapy seems to have its limits.

    Any recommendations on oCBD products that could help?


  13. kyle

    so with cbd is the strength set to per ml? so like if i have a 300mg bottle i take 1ml am i getting 300mg of cbd

  14. Troi

    Hello I’m new to using CBD I have 200 mg oils and a salve. Mainly to treat rheumatoid arthritis swelling and pain but also use as sleep aid. I’ve been using it for about a week and a half…not sure I have the right dose or maybe it’s not working for me. How soon are you supposed to feel if it’s working? Hand has been achy used some salve and oil still achy. I don’t think I’ve had much luck for sleep use either. Should I go up in dose…or does it take awhile to build up into system before you feel results?

    1. Adam

      Not sure which brand you are using, but 200mg is normally used for anxiety, stress and mild conditions

      1. Troi

        Hi Adam I’m using Biologix Super CBD tincture it’s actually 250 mg and the helping friendly salve 200 mg. So for my RA and Sleep do you think I should go up in dosage?

  15. Rose A

    I have decided yo trt cbd beginners oil but im not sure if this is right fir me. In august 2017, i had a stem cell bone marrow transplant due to cancer. My platelets constantly drop and i need weekly transfusions.
    Does anyone know which oil is best for a beginner? How do i know what to get?

  16. Jane Orozco

    Been using CBD for a while. I started with the 300mg and then moved to the 600mg. I then bought the 1000mg, but it was to strong for me. Just didn’t sit right. I think I’ve found that sweet spot with the 600mg. I take it twice a day, half the dropper. Works well for my anxiety and I have been sleeping better

  17. Pat Nash

    I started taking CBD oil 300mg the problem I had I could not sleep anyone else have this side effects?

    1. Adam

      Which brand you using?

  18. Medeah Chew

    I just ordered Go Green Hemp Premium CBD Oil Orange.
    Do you know anything about this brand, good or bad?
    Thank you.
    By the way, I have MS if this means you would recommend a different brand.

    1. Adam

      Sorry Medeah, we’ve never heard of them

  19. Jay

    I having trouble fully understanding the measurements. I’ve seen 500mg CBD 10ml bottles and 500mg 30ml bottles… is one more portant than the other? Is the mg mesurment per bottle? Would that make the 500mg 30ml bottle less potent then the 500mg 10ml bottle? Would I have to use less from the 10ml bottle to get the same amount from the 30ml bottle?

    1. Adam

      Yes there is 500mg in 10ml vs 30ml. So the 10ml bottle will be more potent and will require 1/3 the amount of product to give the same result.

  20. Char

    Hi I’m canadian. Was just wondering if you mail to Canada

    1. Adam

      Hi Chris, we don’t actually sell any products, but I am sure most of the brands do ship.

  21. Joan Williamson

    Someone said that Charlotte’s Web was slow to deliver. I have a sob story to tell you. I’m new to CBD oil and had no idea what that company was like. I ordered on the 5th of the month and received the package on the 28th of the month. As you can see, that’s pretty darn slow. They ended up sending me a second package because they claimed the first one was lost. It wasn’t being tracked at all from day one, which I still can’t figure out. I ordered on the 5th and the invoice said I ordered on the 12th. Please avoid this company if possible. The oil is also too weak to be any good for me. I’m so disappointed but will keep trying. I’m sick to death of pills. Hang in there everyone. I thought this info might be useful to anyone thinking of ordering from CW. They do state it takes three weeks to deliver; add two weeks and you’ve got it.

    1. Steve

      website States that it will take 2-3 weeks to ship, customer service I hear is lacking from many customers. But the product was weak ,What do you mean? CW is said to be the very best did you buy the lowest strength?
