Soft gel capsules have become one of the most popular forms of oral dosage in the pharmaceutical and nutraceutical industries. Their smooth texture, easy-to-swallow design, and ability to encapsulate both oil-based and liquid formulations make them an ideal choice for consumers and manufacturers alike. But have you ever wondered what soft gel capsules are actually made of?
In this complete guide, we’ll explore everything about what soft gel capsules are made of, their components, formulation process, and why Capsoft Healthcare is one of the most trusted names in the softgel manufacturing industry.
Soft gel capsules often simply called softgels are a unique dosage form used to deliver vitamins, minerals, herbal extracts, and pharmaceutical ingredients. These capsules consist of a gelatin-based shell that encloses a liquid or semi-solid fill. They’re known for their appealing look, superior bioavailability, and easy ingestion, especially for those who find it difficult to swallow tablets or hard capsules.
At Capsoft Healthcare, we focus on producing high-quality softgels that meet global pharmaceutical and nutraceutical standards. With years of experience and advanced facilities, we ensure that every capsule delivers precision, safety, and effectiveness.
The core of every softgel capsule lies in two major components — the shell and the fill material. Each plays an important role in ensuring the capsule’s stability, strength, and effectiveness. Let’s break down each part in detail.
The softgel shell acts as a protective coating that holds the active ingredients inside and ensures the product’s stability. Typically, this shell is made of:
Gelatin is the primary ingredient in traditional softgel capsules. It is a natural, protein-based material derived from collagen found in animal sources such as bovine (cows) or porcine (pigs). Gelatin provides flexibility, elasticity, and transparency, giving softgels their distinctive smooth texture.
At Capsoft Healthcare, we use high-quality pharmaceutical-grade gelatin to ensure the safety, purity, and integrity of our softgel capsules. Our gelatin is carefully selected and processed to meet stringent quality standards.
Plasticizers are added to make the gelatin shell soft and flexible. Common plasticizers include glycerin and sorbitol. The amount of plasticizer determines the firmness or softness of the capsule.
Water acts as a solvent that helps dissolve and blend gelatin and plasticizers. It also contributes to the flexibility and strength of the softgel shell. After the manufacturing process, water content is precisely controlled to maintain capsule stability and prevent microbial growth.
To make softgel capsules more appealing and identifiable, coloring agents are used. Natural colorants such as iron oxide, beta-carotene, or titanium dioxide (for opaque capsules) are commonly added. These colors not only improve aesthetics but also help protect sensitive ingredients from light degradation.
Preservatives like methylparaben or propylparaben are sometimes added to prevent microbial growth and extend the shelf life of the capsules.
The fill material inside a softgel is where the active ingredients are stored. The composition of this fill depends on the intended use whether it’s a pharmaceutical drug, dietary supplement, or herbal formulation.
Here’s what the fill typically consists of:
This is the heart of the softgel the main compound responsible for delivering the desired therapeutic or nutritional benefits. Active ingredients may include:
Capsoft Healthcare formulates a huge range of softgel capsules containing premium-grade active ingredients to ensure efficacy and high bioavailability.
Since many active ingredients are fat-soluble, carrier oils are used to dissolve or suspend them. Common carrier oils include:
Emulsifiers such as lecithin are added to stabilize oil-water mixtures inside the capsule, ensuring a consistent and uniform fill throughout the batch.
To prevent oxidation and maintain product integrity, antioxidants such as Vitamin E, BHT (Butylated Hydroxytoluene), or BHA (Butylated Hydroxyanisole) are included in the formulation.
In certain nutraceutical formulations, especially those intended for chewable or flavored softgels, natural flavors and sweeteners are added to enhance palatability.
As consumer preferences shift toward plant-based products, Capsoft Healthcare also offers vegetarian softgel capsules. Instead of gelatin derived from animal sources, these capsules use plant-based alternatives such as:
These materials provide a similar soft, flexible shell while maintaining vegetarian and vegan compatibility. They’re ideal for customers who avoid animal products or have dietary restrictions.
Understanding what soft gel capsules are made of is only half the story. The process of making them is just as critical. At Capsoft Healthcare, we employ advanced encapsulation technology to ensure precision and quality in every capsule.
Here’s an overview of the softgel manufacturing process:
The gelatin or plant-based alternative is mixed with water and plasticizers in a controlled environment until it forms a homogenous, viscous gel.
Simultaneously, the active ingredients and carrier oils are blended under specific conditions to achieve a stable, uniform mixture.
Both the gel mass and fill material are fed into a rotary die encapsulation machine. The machine forms two ribbons of gelatin (or alternative material), which are then filled and sealed simultaneously to form softgel capsules.
The capsules are dried under controlled temperature and humidity conditions to achieve the right moisture balance. They are then carefully inspected for uniformity, shape, and quality.
Once tested and approved, the capsules are packed in blister packs, bottles, or containers ready for distribution and consumption.
