Softgel Capsules 101: What They Are and How They Work

What are Softgel Capsules?

Softgel capsules, often simply referred to as softgels, are a type of encapsulation that contains a liquid or semi-liquid substance within a soft, flexible outer shell.

The outer shell of a softgel capsule is typically made from a blend of gelatin, water, and a plasticizing agent, like glycerin, which provides the capsule’s softness and flexibility. In recent years, alternatives to gelatin have been developed to cater to vegetarian and vegan consumers, using substances like agar or modified starches.

In essence, soft gel capsules offer a versatile, protective, and often more palatable way to deliver a range of active ingredients, making them a popular choice in both the health supplement and pharmaceutical industries.





Components of Softgel Capsules

Softgel capsules consist of two primary components: the outer shell and the inner fill. Here’s a breakdown of these components:


1. Outer Shell

The outer shell of a softgel capsule is soft and pliable, designed to encapsulate liquid or semi-liquid contents. Its main components include:

  • Gelatin: Traditionally, gelatin is the primary ingredient used to produce the outer shell of softgel capsules. Gelatin is derived from collagen obtained from various animal by-products, making it a natural protein. It offers the softgel its characteristic elasticity and strength.
  • Glycerin (Glycerol): Glycerin is used as a plasticizer, giving the softgel its soft and flexible nature. It helps in maintaining the moisture content, ensuring the capsule remains soft and doesn’t become brittle.
  • Water: Water is used in combination with gelatin and glycerin to form the gel matrix of the outer shell.
  • Opacifying Agents: In cases where the contents need protection from light, opacifying agents can be added to make the softgel shell opaque.
  • Colorants and Dyes: These can be added for aesthetic reasons or to differentiate dosages.
  • Preservatives: These might be added to prolong the shelf life of the capsule.
  • Alternative Materials (for vegetarian/vegan softgels): For those who avoid animal products, there are plant-based alternatives to gelatin, such as carrageenan, starch, or agar, used to form the outer shell.

2. Inner Fill

The contents inside a softgel can vary widely based on the intended use. They can include:

  • Oils: Many softgels contain oils, whether it’s fish oil for omega-3 supplements, flaxseed oil, vitamin E, or CBD oil, among others.
  • Active Ingredients: This refers to the primary component or components that provide the therapeutic or nutritional effect, such as vitamins, minerals, herbs, pharmaceuticals, etc.
  • Solvents: These can be used to dissolve certain ingredients to ensure a homogeneous mixture.
  • Preservatives: These may be added to maintain the stability and longevity of the contents.
  • Emulsifiers and Surfactants: These agents help stabilize the contents, especially if combining oil and water-based ingredients.
  • Flavoring Agents: In some cases, flavors might be added to mask any undesirable taste of the active ingredients.


Advantages of Softgel Capsules

Softgel capsules offer a range of advantages over other delivery forms, making them a popular choice in both the pharmaceutical and health supplement industries. Here are the primary benefits of softgel capsules:

  1. Enhanced Bioavailability: Due to their lipid-based outer shell and the ability to encapsulate oil-soluble ingredients, softgels can improve the bioavailability of certain compounds, ensuring better absorption in the body.
  2. Ease of Swallowing: Their smooth and soft texture often makes softgels easier to swallow compared to hard-shell capsules or tablets. This can be especially beneficial for elderly individuals or others who may have difficulty swallowing larger or more rigid forms of medication or supplements.
  3. Odor and Taste Masking: The sealed outer shell of a softgel can effectively mask any unpleasant tastes or odors of its contents, making the consumption experience more palatable.
  4. Protection of Sensitive Ingredients: Softgels can protect ingredients from exposure to light, air, and moisture. This is crucial for ingredients that are sensitive to oxidation or degradation, as it ensures the ingredient retains its potency and efficacy.
  5. Precise Dosing: Softgels provide a consistent and precise dose of the active ingredient, ensuring that users receive the same amount in each capsule.
  6. Flexibility in Formulation: Softgels can house a wide variety of ingredients, from oils to suspensions. This flexibility allows for diverse formulations that might not be suitable for other dosage forms.
  7. Aesthetic Appeal: With the option to customize the color, size, and shape, softgels can be made visually appealing to consumers. Their often transparent or translucent nature can also give a “pure” or “clean” impression, potentially increasing consumer trust.
  8. Potential for Controlled Release: Softgels can be formulated to allow for controlled or targeted release of their contents, ensuring a sustained or specific site of action in the body.
  9. Stability: The hermetically sealed environment of a soft gel can enhance the shelf life of certain products by reducing the risk of ingredient interaction or contamination.
  10. Consumer Preference: Due to their ease of use, visual appeal, and the absence of an aftertaste, many consumers prefer softgels over other forms of supplements or medications.


CBD and Softgel Capsules

CBD, or cannabidiol, is a sensitive compound that can degrade when exposed to light, air, or heat. The protective nature of softgels makes them an ideal choice for CBD, safeguarding the compound’s integrity. Moreover, the lipid solubility of CBD aligns well with soft-gel encapsulation, potentially optimizing its absorption in the body.

There’s a myriad of CBD products on the market, from tinctures to edibles. Softgel capsules stand out for several reasons. Their bioavailability can often be superior due to the potential for better absorption. Softgel capsules also offer the convenience of portability and discretion, making consumption easy and unobtrusive. Moreover, each soft gel provides a consistent dose of CBD, ensuring predictable effects.




Production Process of Softgel Capsules

  • Raw Material Acquisition: The quality of a softgel capsule starts with its ingredients. Top manufacturers prioritize sourcing high-quality gelatin and premium-grade CBD oil to ensure the product’s effectiveness and safety.
  • The Encapsulation Process: Softgel encapsulation, especially via the rotary die method, involves the simultaneous preparation of the gelatin ribbon and the injection of the fill material. This ensures a consistent dose in each capsule and a seamless design that safeguards the contents.
  • Quality Control & Testing: Third-party lab testing is vital in verifying the potency, purity, and safety of CBD softgel capsules. These tests ensure that the product is free from contaminants and matches the labeled potency, offering peace of mind to consumers.



How to Choose the Right CBD Softgel Capsule

Choosing the right CBD softgel capsule involves several considerations to ensure you’re getting a quality product that fits your needs. Here’s a comprehensive guide to help you make an informed choice:


Strength or Potency

  • Dosage: CBD softgels typically come in a range of dosages, from 5mg to 50mg or more per capsule. Determine your dosage needs based on your specific health concerns, body weight, and advice from a health professional.
  • Lab Results: Always look for a product that has its potency verified through third-party lab testing to ensure you’re getting the amount of CBD stated on the label.



There are three main types of CBD extracts:

  • Full-Spectrum: Contains all compounds found in the cannabis plant, including CBD, minor cannabinoids, terpenes, and trace amounts of THC (usually below 0.3%).
  • Broad-Spectrum: Includes multiple compounds from the cannabis plant but has no THC.
  • Isolate: Pure CBD with no other cannabinoids or terpenes.
  • Additional Ingredients: Some softgels may contain added ingredients like melatonin for sleep, curcumin for inflammation, or other vitamins and minerals. Ensure these additions fit your needs and that you’re not allergic to any of them.


Brand Reputation and Transparency

  • Reviews: Look for brands with positive reviews and testimonials.
  • Source of Hemp: Quality CBD products often source their hemp from reputable farms, usually within the U.S. or Europe.
  • Extraction Method: The CO2 extraction method is considered the gold standard as it preserves the purity of CBD without using harmful solvents.
  • Third-Party Lab Testing: This is crucial. Always opt for brands that provide lab results confirming the product’s potency, purity, and safety.


Proper Storage and Shelf Life

  • Packaging: Look for softgels packaged in dark or opaque bottles to protect against light degradation.
  • Shelf Life: Check the expiration date. While CBD doesn’t typically “go bad,” its potency can diminish over time.

  • Price per mg: To determine the value, divide the price of the product by the total mg of CBD in the bottle. This gives you a cost per mg, allowing for easier comparison across brands and products.


Type of Softgel Material

For those who avoid animal products, ensure the softgel is not made from gelatin but from vegetarian or vegan-friendly alternatives.


Company Policies

  • Return Policy: A solid return policy indicates confidence in the product.
  • Customer Service: A responsive customer service team can be a testament to the company’s commitment to its customers.


Personal Preferences

  • Size of Capsule: Some might prefer smaller softgels for easier swallowing.
  • Additional Benefits: As mentioned earlier, some softgels might offer added benefits like aiding sleep or inflammation.
