Empty Capsules

Empty Capsules allow you to combine powdered supplements into custom formulas, exactly as you want them. By encapsulating your own powders at home, it’s possible to cut out the additional costs associated with pre-encapsulated supplements, meaning you’ll save money while creating your personalized capsules.

How to create your own capsules?

Creating your own capsules is very easy. All you need is one of our easy to use capping kits, some empty capsules and the powder that you want to encapsulate. If you haven’t already got a capping kit, then you can find them here, along with a range of empty capsules.

Which size capsules?

Our most popular empty capsules are size 00 which hold around 380-950mg of most powders. If you are making your own capsules for the first time, then size 00 would be a good size to try first.

Our full range of empty capsules goes from size 000 to 4. Our largest capsules are size 000, holding approximately 550-1350mg of powder. Our smallest empty capsules are size 4, which hold approximately 75-150mg of powder. Empty capsules are measured in terms of the volume they can hold, that is the amount of space inside the capsule. However, the exact amount of powder a capsule can hold is dependent upon the density of the powder you are using. If your powder is very dense then your capsules will hold more powder. If your powder is not very dense then your capsules will hold less powder. The table below shows how much each size of capsule can hold for different powder densities.


Size 000 Size 00 Size 0 Size 1 Size 2 Size 4

Powder Density Approximate Fill Weight
0.4g/ml 548mg 380mg 272mg 192mg 148mg 75mg
0.6g/ml 822mg 570mg 408mg 288mg 216mg 126mg
0.8g/m 1096mg 760mg 544mg 384mg 288mg 168mg
1.0g/ml 1370mg 950mg 680mg 480mg 360mg 210mg

What if I don’t know my powder density?

As a general rule of thumb, most powders fall around the 0.6-0.8g/ml mark. However, very fluffy powders should be considered to be around the 0.4g/ml mark, whereas fine granular powders (similar to sugar) would be 0.8-1g/ml.

Vitamin C has a powder density of 0.95g/ml. A 00 capsule will hold approximately 950-970mg of Vitamin C powder. A size 0 capsule will hold approximately 680-700mg of Vitamin C powder.
