Capsule Sizes
What's the importance of your capsule size?
Taking the proper amount of time to research the correct capsule sizes will save you valuable time and cost regardless of whether you are a seasoned professional or a new starter. At Arena Health we specialise in 2 piece capsules. The capsule sizing charts on this page are extremely helpful tools to help you decide what capsule size you need for your supplement, mineral or vitamin blend.We can manufacture in sizes 00, 0, 1 and 3 in both HPMC and gelatin capsules.For more information about the data below, please do not hesitate to contact us through our contact form or call us on 01425 550543
Mass
Empty weight of the capsule without product measured in milligrams (mg)
Tolerance
The allowable variance in dimensions that is allowed prior to a product being considered flawed and/or unfit for sale.
Volume
The total volume of the inside of the capsule in milliliters (ml)
Capsule Capacity
The total weight capacity of the capsule measured in milligrams (mg) depending on the density of your formulation.
Points to think about
- Maximum length and diameter of the capsule that can be ingested
- Intended dosage
- Density of your filler material
- The size of capsule your designated filler machine can take
- The type of capsule you want.
Understanding capsule sizes is the most important step in determining exactly how much dosage is in one serving. Capsule sizes are labeled with a numerical value, from 000 to 5.
The basics of capsule sizing:
Capsule Size 1-5: The higher #= smaller size
Capsule Size 0, 00 and 000: Less 0s = smaller capsule size
Capsule sizes can be selected on many factors, one being the actual size of the capsule. This is important to consider when choosing a capsule for a pet or a child who may have limitations as to the diameter or length of the capsule they can ingest. For other applications, additional factors such as aesthetics or dosage determine the size of the capsule.
Once you know the filler density and the dosage, use our capsule sizes chart to see which size capsule will best accommodate these needs.
To deliver the intended dosage, you can either try to fit multiple servings into a larger capsule such as the 000 or divide the serving among several smaller capsules such as 0s and 1s. Because these smaller capsule sizes are easier to swallow, they are most suitable for children and smaller pets.
