How long does CBD oil last in the bottle? All you should know

Many people considered the interest in CBD to be a fad and never thought it would sustain this long. But in actuality, its popularity continues to grow. Every day, more people pick up a bottle of CBD oil or any other form of CBD and begin their journey with the supplement. But as always, there are questions. Many consumers often want to know how long does CBD oil last.

CBD enthusiasts want to know which quantity best suits them. They also want to know if there is a way to extend the shelf life of their current bottle of CBD oil. We all want to reap the maximum benefits for every pound we spend. Read on to find answers to all these questions and more.

How long does CBD oil last?

The simplest way to know how long the bottle you have just ordered will last is a simple calculation. Ultimately, there are two things you'll need to calculate:

  • the total amount of CBD in your bottle
  • and your daily dose of CBD
  • Side note: if you are new to CBD - use the recommended dose for your weight.

On the product label, you will find the information on the total amount of CBD in milligrams. Ideally, it should be there, but if you can’t see it, check out the website for a detailed description of the product. Once you have the two figures, divide the total amount of CBD with the daily dose. 

The answer is the number of days the bottle of CBD oil will last.

Assuming we have a bottle of CBD oil with a total CBD of 300mg and an individual who consumes 50mg per day. 

300mg/50mg = 6 days

Remember to add up the CBD if you take it several times a day to get the daily dose. For example, if you take 10mg three times a day daily - 30mg. Also, you should not exceed the recommended daily dose of 75mg.

What quantity should you buy to last a specific period?

You may not have many choices when it comes to CBD oil bottle sizes, as most come in the 30ml bottle. The quantity that varies widely is the amount of CBD in each bottle. You can find some containing as low as 250mg, while others may go as high as 3000mg.

Experts recommend beginners to begin with the low concentration CBD oil and low dose. You can calculate based on your weight and start from there. Experimentation is key in finding your optimum dose. Take the same dose for a week and record how you feel daily. Make necessary adjustments if need be.

To make these calculations, you need the number of days you want the oil to last and your daily dosage. By multiplying the two, you will have the quantity that you need to buy. For instance, if you need the CBD oil to last 15 days and you take a maximum of 20mg daily. Then;

15days * 50mg = 750mg, 

You will require 750mg of CBD.

Now that you know how to calculate the amounts you need, let’s find out how long before the bottle you bought last year goes bad.

Does CBD oil expire?

Buying CBD oil in bulk can be very cost-effective, and because you are using it daily, it makes sense. Most CBD products except edibles are viable for 14-24 months. CBD oil does not go bad in the usual sense, but it loses its efficacy. You can slow or speed up this degradation depending on how you take care of it.

Certain conditions, like exposure to sunlight and heat, can shorten the shelf life of your CBD oil so that you can enjoy the maximum benefits for the longest time. Using CBD oil past its expiry date is not harmful to you, but the CBD may not be effective.

But if your CBD oil smells funny, it has probably gone bad, which is rare - but it can happen. Do not take CBD oil in this case. CBD oil packed in dark green or amber bottles lasts longer. Science has proven that the colours protect the contents of the bottle from UV rays.

The choice of carrier oil also plays an essential factor in the shelf life of CBD oil. CBD oil using coconut MCT carrier oil lasts longer than those that use hemp as a carrier oil. Also, some additives may reduce the shelf life of CBD oil. The quality of CBD oil also matters, with low-quality oils having a reduced shelf life. 

Another factor that determines how long CBD oil lasts is storage conditions.

How to store CBD oil for prolonged efficacy

Though darkened bottles are favoured as they preserve the potency of CBD oil, you also need to store it under the right conditions to reduce speedy degradation. By following these simple instructions, you can extend the shelf life of your CBD oil.

The best place to store CBD oil is a cool, dark place. A cabinet or drawer in the bedroom is an ideal place away from sunlight. Avoid window sills at all costs.

Keep CBD oil away from heat. You can refrigerate, but it is not a must. Avoid places near oven and radiator as the temperatures around are high; the ideal temperature is about 250C

Oxidation also leads to degradation. To prevent it, keep the container tightly closed. Reduce the time you expose the CBD oil to the air when you are using it. Always keep the oil in an upright position.

Excess moisture and humidity are not good for CBD oil. Bathrooms and kitchens are not suitable as the risk of exposure to water are high. 

If you live in an area that experiences high temperatures and sunlight, do not store your CBD oil in the car. 

When you travel with your CBD oil, wrap it with aluminium foil to protect it from light. 

Can you use CBD oil past its expiry date?

On the product label or the CBD oil bottle, you will find an expiry date. The expiry date shows the time which the CBD oil loses its potency. However, the oil is not necessarily bad. Taking it is not dangerous for your body.

But, unless you are dealing with pure 100% CBD carrier oil and other additional additives added to CBD oil, it may spoil within that period. Additives may go bad because of the extended time, and it is wise to use the oil before the expiry period. 

Also, when buying, check the manufacturing date to avoid products that have been sitting for a long time.

How long does CBD oil last at room temperature?

When you store CBD oil at room temperature in the right conditions, it will remain potent for 24 months. However, if you expose it to sunlight, heat, or moisture, you reduce the efficacy significantly. Experts recommend using CBD oil before the best before date.

How long does CBD oil last in the refrigerator?

The fridge provides a cool dark environment for storing CBD oil. It is especially favourable if you live in a humid climate. The refrigerator can extend the shelf life of CBD oil for one to ten months. This is because it prevents the CBD oil from degrading as quickly. 

Can you freeze CBD oil?

Buying oil in bulk is very cost-effective, and you can freeze the oil for longer storage. Most CBD oil freezes without problems, but your suppliers will advise you better if you are unsure. But while it is okay for long-term storage, it is not suitable for everyday use as you have to keep thawing.

Takeaway on how long does CBD oil last

You can calculate the amount of CBD oil you require for a specific period and buy the oil in bulk. This is very cost-effective, and you can store the extra oil. When kept in favourable conditions, the CBD oil should keep for one to two years. You can check the expiry date of your CBD oil on the label or from the supplier’s website.

To extend the shelf life of your CBD oil, keep it in a cool, dark place away from moisture. The best places to store your CBD oil are in a drawer, cabinet, or cupboard in the bedroom or living room. The kitchen and bathroom are tricky because of the presence of moisture and heat. 

Ensure you buy your CBD oil from credible suppliers, as quality also impacts the shelf life.
