Aug 28, 2025Leave a message

Gelatin empty capsules are a crucial component in the pharmaceutical, nutraceutical, and cosmetic industries. They serve as a convenient and effective way to encapsulate various substances, including medications, supplements, and herbal extracts. One of the key aspects of gelatin empty capsules is their different sizes, which are designed to accommodate different volumes of fill material. In this blog, as a gelatin empty capsule supplier, I will explore the various sizes of gelatin empty capsules, their applications, and how to choose the right size for your specific needs.

Standard Sizes of Gelatin Empty Capsules

Gelatin empty capsules come in a range of standard sizes, which are typically designated by a numerical system. The most common sizes are from size 000 to size 5, with size 000 being the largest and size 5 being the smallest. Here is a detailed breakdown of these standard sizes:

Size 000

Size 000 is the largest standard size of gelatin empty capsules. It has a capacity of approximately 1.37 ml, making it suitable for encapsulating large volumes of powders, granules, or liquids. This size is often used for supplements or medications that require a high dosage. For example, some herbal supplements that are taken in large quantities may be encapsulated in size 000 capsules.

Size 00

Size 00 capsules have a capacity of around 0.95 ml. They are also commonly used in the pharmaceutical and nutraceutical industries. This size is a popular choice for encapsulating a variety of substances, including vitamins, minerals, and herbal extracts. It provides a good balance between capacity and ease of swallowing.

Size 0

With a capacity of approximately 0.68 ml, size 0 capsules are another widely used size. They are suitable for a range of applications, from encapsulating small to medium doses of medications or supplements. Many over - the - counter medications are available in size 0 capsules due to their moderate capacity and relatively easy ingestion.

Size 1

Size 1 capsules have a capacity of about 0.5 ml. They are often used when a smaller dosage is required. This size is also easier to swallow for some people, especially those who have difficulty taking larger capsules. Nutraceutical products that are formulated in lower concentrations may be encapsulated in size 1 capsules.

Size 2

Size 2 capsules can hold around 0.37 ml of fill material. They are commonly used for encapsulating substances that require a relatively small dosage, such as some homeopathic remedies or high - potency supplements where only a small amount is needed.

Size 3

Size 3 capsules have a capacity of approximately 0.3 ml. This size is suitable for encapsulating very small doses of medications or supplements. It is often used in the production of specialized pharmaceutical products or for substances that are highly concentrated.

Size 4

Size 4 capsules can hold about 0.21 ml of fill material. They are used for encapsulating extremely small doses, typically for substances that are very potent. Some pharmaceutical research products or experimental medications may be encapsulated in size 4 capsules.

Size 5

Size 5 is the smallest standard size of gelatin empty capsules, with a capacity of around 0.13 ml. It is mainly used for encapsulating very small amounts of high - potency substances, such as certain hormones or rare herbal extracts.

Applications of Different Sizes of Gelatin Empty Capsules

The choice of capsule size depends on several factors, including the nature of the fill material, the required dosage, and the target market. Here are some common applications for different capsule sizes:

Pharmaceutical Industry

In the pharmaceutical industry, the size of the capsule is carefully selected based on the dosage of the active ingredient. For example, medications with a high dosage, such as some antibiotics or painkillers, may be encapsulated in larger sizes like 000 or 00. On the other hand, medications with a low dosage, such as some anti - anxiety drugs or hormonal therapies, may be encapsulated in smaller sizes like 3, 4, or 5.

Nutraceutical Industry

The nutraceutical industry uses gelatin empty capsules to encapsulate vitamins, minerals, herbal extracts, and other dietary supplements. Larger capsule sizes like 000 and 00 are often used for multi - vitamin supplements or herbal blends that require a high dosage. Smaller sizes like 1, 2, or 3 are used for single - ingredient supplements or those with a lower recommended dosage.

Cosmetic Industry

In the cosmetic industry, gelatin empty capsules can be used to encapsulate cosmetic ingredients, such as essential oils or plant extracts. The size of the capsule depends on the amount of ingredient to be encapsulated and the intended use. For example, a single - use cosmetic capsule may be a smaller size, while a larger capsule may be used for a more concentrated formula.

Factors to Consider When Choosing a Capsule Size

When choosing the right size of gelatin empty capsules for your product, there are several factors to consider:

Dosage Requirements

The most important factor is the dosage of the fill material. You need to ensure that the capsule size can accommodate the required amount of the active ingredient. If the dosage is too large for a particular capsule size, it may not be possible to fill the capsule properly, or the capsule may burst during the filling process.

Ease of Swallowing

The size of the capsule also affects its ease of swallowing. Larger capsules may be more difficult to swallow for some people, especially children or the elderly. Therefore, if your target market includes these groups, you may want to consider using smaller capsule sizes.

Fill Material Properties

The properties of the fill material, such as its density, flowability, and particle size, can also influence the choice of capsule size. For example, a dense powder may require a larger capsule size to achieve the desired dosage, while a free - flowing powder may be more easily filled into a smaller capsule.
