How to Calculate CBD Dosage -Holland and Barrett Example

I’ll show you how to calculate CBD Dosage so that when you buy a CBD Oil you know you are buying the best CBD Oil for you.


No matter who you are or your reasons for using CBD we all start on the same amount of between 0-25mg a day.

In my experience, the vast majority of people are fine to start on 10mg CBD a day. However, if you are sensitive to supplements or feel wary then by all means just start with 5 mg.

After 7 days we can then double the amount we are using and 7 days later we can double again if we feel it necessary. The maximum daily allowance for CBD in the UK is 70mg.

When you buy a CBD oil the CBD supplier will give you some dosage instructions on the label. However, these are only guidelines as they don’t know how much CBD you need and neither do I. The only person who knows what’s best for you …. is you. And you find this out by starting on a small amount and increasing gradually until you find your own personal CBD Sweet spot.

There are some theories of thought that how to calculate CBD Dosage is based on your body weight. There isn’t any science to back this theory up though and that’s because we are all wonderfully unique.

With so many differences between us you can’t give a one size fits all dosage. It’s not possible and that’s because there are so many differences. We all have different bodies and lifestyles.

Plus we also add more variety by

  • Using Different CBD Suppliers
  • CBD Oil Strengths
  • Qualities of CBD Oil

So no matter why we are starting CBD we all start small and gradually increase. Listening to our bodies and adjusting accordingly.

To do this though we need to know how many MG we are taking so then we can decide if we want to increase or decrease the dosage. Or we may decide to change CBD Brands. To choose an alternative CBD Oil you first need to know how much CBD in MG you are currently using.

Reputable CBD Suppliers will give this information on the label so you don’t need to calculate it yourself. As you can see here with Canabidols 500mg CBD Oil.

You can see from the label to get 25mg of CBD you would need to have half a pipette

You get 20 servings of 25mg so this would last 20 days if you used 25mg a day or 10 days if you used 50mg a day.

This information is vital so you can understand how much it will cost for you to use that amount and also how long the bottle will last.

If for example you started to use CBD Oil and came to the understanding that you personally needed 50mg a day (which is a large amount in my experience) then you may want to buy the next strength up like a 1000mg or 2000mg bottle.

You would move up to the next strength because it would last longer and because usually higher strengths have more MG per serving so you don’t need to have as many drops.

How to Calculate CBD Dosage – Holland & Barrett Example

If the CBD oil doesn’t give you the amount of MG CBD you get per serving then here is a calculation for you to work it out for yourself. I’ll use the 2.75% CBD Oil from Holland and Barrett as an example.

  • Firstly we need to take the total MG of CBD in the bottle
  • Second, we divide this by the number of drops or pipettes in the bottle. A 10ml bottle will usually hold 240 drops. 
  • This then gives us MG CBD Per drop/pipette
275mg CBD In Total in the Bottle 
240 drops In Total in the Bottle 
275mg/240drops = 1.14mg CBD Per Drop 



So if you want to use 10mg a day you will need 9-10 drops a day
