How Long Will a Bottle of CBD Oil Last?
A bottle of CBD oil can last anywhere from a couple of days to over a year. It all depends on how much CBD is in the bottle and how much you take per day.
This is a common question for people who are getting into CBD and deciding on the right CBD oil to buy to save money and the hassle of multiple purchases.
Here’s everything you need to know about how long a bottle of CBD oil will last you, its shelf life, and related questions.
How Long Will My CBD Oil Last?
To figure this out, you’ll need to know the total amount of CBD in your tincture and how much of it you take daily in milligrams (mg). Then, you can simply divide the CBD amount by your daily dose.
Let’s say your CBD oil contains 900 mg of CBD. If you take a 30 mg CBD dose once a day, this CBD oil will last you 900/30 = 30 days. Alternatively, let’s say you take a 15 mg CBD dose every two days. This means the oil will last you (900/15)x2 = 120 days.
If you need help figuring out how much CBD you’re taking per dose, many CBD products will list how much CBD is in a serving or one dropper, but that’s not always the case.
If the amount is not listed, you should check the volume of your bottle. Most CBD oils come in 30 ml bottles but sizes can range anywhere from 5 ml to 120 ml.
It’s also helpful to know that one full dropper of CBD oil is roughly equal to one ml of liquid or about 20 drops.
So if you have a CBD oil with 900 mg of CBD in a 30 ml bottle, that means one full dropper (1 ml) will contain 30 mg. Meanwhile, one drop of this oil will be roughly 30/20=1.5 mg of CBD.
Now, you can simply multiply the number of drops you’re taking to figure out your daily dose. Then, you can divide the total CBD content by that number to see how many days your 30 ml bottle will last.
How to Choose a CBD Oil That Will Last As Long As You Need
What about when you need to choose a product that will last you a certain length of time?
The amount of CBD in a tincture can vary greatly from as low as 250 mg to as high as 7500 mg. This means you need to find the product whose total CBD content matches your desired dosage and the length of time you need the oil to last.
Let’s say you’re a new CBD user who wants to take 10 mg of CBD per day and have the bottle last for 30 days. In that case, you’ll need an oil that will last 10 mg times 30 days, so it has to contain at least 300 mg of CBD.
Or, if you want it to last 90 days, then you need an oil with at least 10×90 = 900 mg. What about one year (365 days)? 10×365 = 3650 mg.
Meanwhile, if you’re an experienced CBD user, you’ll likely be using larger doses. In that case, simply multiply your daily dose by the number of days you need the bottle to last, and buy oil that contains at least that much CBD.
Again, keep in mind that if you don’t use CBD daily, you’ll need to do some additional calculations. For example, let’s say you use 50 mg of CBD per week and you want your CBD oil bottle to last you 3 months.
One month is roughly 4 weeks, so that’s 200 mg of CBD per month. Times that number by 3 months, which means you need a 600 mg bottle of CBD oil.
How Long is CBD Oil’s Shelf Life?
It’s also helpful to know the shelf life of CBD, especially if you want your product to last for months.
Assuming that you store your CBD oil properly — in a cool, dark, dry place away from any heat and humidity — most CBD oils have a shelf life of 14 months to over a year.
Your safest bet is usually the fridge, although you can also store CBD in a dark cabinet as long as the room doesn’t get too hot.
Another factor that will affect the shelf life is the carrier oil. All CBD oils contain a carrier oil, which is the ingredient that helps your body absorb CBD better. The vast majority of CBD oils use coconut-derived MCT oil, which is known for its long shelf life of about two years.
Other carrier oils, such as hemp seed oil, have a shorter shelf life, but it’s still more than long enough for most people’s needs.
In that sense, as long as you store CBD oil correctly, you don’t have anything to worry about.
Having said that, if your CBD oil smells very different from when you purchased it and the oil looks very cloudy, it may have gone bad and you should throw it away. It’s usually very apparent and easy to tell if your oil is expired.

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)
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.
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.
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.
