how long should a bottle of cbd last?

how long should a bottle of cbd last? (with illustrations)

does a bottle of cbd last a long time? you may be looking into buying your first bottle of cbd oil, or maybe you recently did. either way, there are a lot of products out there at different sizes and prices, and we think it’s only right for you to be in the know on all the factors that can go into answering the following question: how long should a bottle of cbd last?

how long a bottle of cbd lasts depends on a variety of factors, including both the volume (in milliliters) and the concentration of cbd (in milligrams) inside the bottle, as well as the amount of cbd one takes in a setting and how often one is consuming cbd.

cbd is used for a wide range of reasons ranging from ailments to as a health supplement, and that number will continue to grow as as we keep learning more about cbd and its role with the human body (and all other animals too). different doses are optimal for different conditions and will have different effects on different people, with individual body chemistry only adding to the fun.  

 

high-potency cbd tinctures are critical

ever see a label on a cbd tincture that looks something like this: “1,000mg / 30ml” and wonder what it means? we gotchu - let’s first take a second to break it all down, and then we can tackle the more important -task of applying what it all means. 

the first number you see in that denotation (in this example it’s 1,000mg) is the amount of cbd present in a given bottle of cbd oil. as you can see, it is measured in milligrams (mg), which is a measurement of mass and is expressed in weight. this is similar to many other nutrients we consume regularly: vitamin c, calcium, sodium, potassium, and iron are only a handful of vitamins and minerals that are measured in milligrams. similarly, mind-altering substances such as caffeine and thc are also measured in milligrams.

like thc, cbd is fat-soluble. therefore, a given mass of cbd must bind to a fat in order to preserve its condition. enter carrier oils such as olive oil and mct oil: these “healthy fats” are the perfect means of keeping your cbd tincture potent (hopefully) and intact. of course, these oils are liquids, and we measure liquids in terms of volume, such as ounces or liters. here’s where the “milliliters” part of the formula comes into play: when all is said and done, the end formula has a certain mass (mg of cbd) that has been absorbed into a certain volume (ml of tincture).

to put that all into the aforementioned formula, “1,000mg / 30ml” means that there are 1,000 mg of cbd in the bottle, and that bottle contains 30ml of the finished product, which in this case is a cbd oil tincture.

 

understanding the potency of your cbd oil 

now that we know how to read a bottle’s ratio of mg per ml, we can do some simple math to understand the potency of a given bottle of cbd. and even if math scares you, you can probably proceed without doing any basic calculations. let’s look at two examples.

  • bottle 1: 1,000mg / 30ml
  • bottle 2: 500mg / 30ml

can you figure out which is more potent? obviously, both bottles are the same volume of 30ml, but the first example has 1,000mg of cbd and the second has half that amount. what that really means is you need to take twice as much of the 500mg tincture in order to consume the same amount (mg) of cbd s the 1,000mg tincture! so basic math shows us that if you were taking 25mg per day of cbd as an example, bottle 1 would last you 40 days, while bottle 2 would last you only 20 days.

some bottles of cbd will also tell you how many ml are in a full dropper, and the even cooler ones will a) do the math for you and tell you how many milligrams of cbd you’re getting in each dropper, and b) measure out the dropper so that you can accurately gauge a fraction of a full dropper. of course, we are happy to do all of these things because we want to help you eliminate the guesswork as much as possible: in a full-sized zadaka tincture, one full dropper is 1ml. the bottle itself is 30ml and contains 1,000mg cbd. let’s try another example.

  • bottle 1: 1,000mg / 30ml
  • bottle 2: 333mg / 10ml

did you come to the conclusion that these two examples have the same potency? both the amount of cbd and overall volume of the tincture are in the same ratio, meaning the tinctures in question have the same potency despite being differently-sized bottles. 

in both cases, a 1ml dropper contains 33.33mg cbd. a half-full dropper full would then have 16.66mg cbd, as it only contains 0.5ml of the overall tincture. knowing this information can help you figure out an accurate dosage size, and can furthermore help you assess how long a bottle of cbd will last you. mental math can do the trick just fine: for example, if you’re taking one full dropper a day (1ml) from a 30ml bottle, then your bottle will last you 30 days, or basically a month. 

bonus tip - this information can also help you assess the price value of your cbd oil. you can divide the price of a bottle of cbd by the amount of mg cbd inside it in order to figure out the price per mg that a bottle of cbd will cost you.

 

how much cbd are you taking, and how often?

since we learned that the potency of a tincture affects the volume of cbd you take (as well as how long a bottle will last), it’s also worth noting that you can figure out how long a bottle of cbd will last you in terms of number of doses as well. let’s stick to the example of a bottle that contains 1,000mg of cbd inside it. regardless of the volume, we can do some easy math to figure out the number of doses you would have in a given bottle. here’s a chart that illustrates this a little better. (we should make this a better graphic obv)

cbd size and number of doses

by looking at this chart, you can see how many doses your bottle of cbd will last you if your tincture is 1,000mg. this is true regardless of the volume (ml) of your tincture; it just means that a less-concentrated tincture will require you to consume more of the tincture for an equivalent amount of cbd. we can also compare some other sized tinctures to break things down a little more.

cbd doses per bottle

while the potency is important, the price per mg is also critical. this chart could be valuable if you find a less-potent tincture for a lower overall relative cost, and it’s important to see that the amount of cbd in a tincture has a direct relationship to the number of doses in said tincture, regardless of your dose size. 

lastly, knowing the number of doses you have in a bottle is also valuable when factoring in how often you are taking cbd. some people like to take it multiple times per day, whereas others may take it once in the morning and be done with it. it’s worth paying attention to your own consumption habits in this regard, as a person who takes one 1ml dropper once a day will go through a bottle less than a person who takes half a dropper three times per day. 

 

closing thoughts

all four of the factors mentioned in this article can help you figure out how long a bottle of cbd oil will last you. regardless, there is no one-size-fits-all model to cbd and the human condition. while we cannot medically recommend or prescribe dosage sizes for people who take cbd, we do hope to provide you with some information that can help make your cbd journey more navigable.

we know there are a lot of variables when it comes to your cbd journey. science continues to improve our understanding of the cannabis plant and our relationship with it, but there are still a lot of gray areas, especially when it comes to individual body chemistry and individual experiences with the cannabis plant as a whole. despite all of this, we hope to have given you all the information you need to combine with your own cbd experience to figure out how long a bottle of cbd will last.
