In health food contract manufacturing, an "animal-based capsule" refers to a type of capsule made from animal-derived materials. These capsules are typically composed of gelatin, which is a protein obtained from the collagen found in the skin, bones, and connective tissues of animals.

Gelatin capsules are widely used in the pharmaceutical and health food industries for encapsulating various powdered or granulated ingredients. They provide a convenient and easy-to-swallow form for oral administration of dietary supplements, vitamins, and other active ingredients.

Gelatin capsules are preferred for their versatility, as they can accommodate both hydrophilic (water-soluble) and lipophilic (fat-soluble) substances. The gelatin shell of the capsule provides a protective barrier for the enclosed ingredients, helping to preserve their stability and enhance their shelf life.

It's important to note that gelatin capsules are derived from animal sources and may not be suitable for individuals following specific dietary restrictions or those with religious or cultural considerations. Alternative options, such as vegetarian or plant-based capsules, are available for those seeking non-animal alternatives.
