Gelcaps

Gelcaps, also known as softgels, are a common dosage form for oral medications and supplements. They consist of a gelatin or vegetarian capsule that encloses a liquid, semi-solid, or powder fill. The outer shell is typically made from gelatin derived from animal collagen, although vegetarian alternatives using plant-based ingredients like carrageenan are also available.

The primary advantage of gelcaps is their ease of swallowing due to the smooth, pliable nature of the shell. The liquid fill can also lead to faster absorption of the active ingredient compared to solid dosage forms like tablets. This is because the contents are already in a liquid or semi-solid state, bypassing the need for dissolution in the stomach.

Gelcaps are suitable for a wide range of substances, including vitamins, minerals, essential fatty acids, and various pharmaceutical drugs. The liquid fill can also mask unpleasant tastes or odors of certain compounds. The manufacturing process involves encasing the fill within two precisely fitted halves of the gelatin shell, which then seals to form a complete capsule. They are generally stable and protected from degradation by environmental factors like light and moisture. Gelcaps are widely used in the pharmaceutical and nutraceutical industries for delivering a variety of active ingredients.
