Depending on the target market, formulation, and fill, manufacturers tend to control the type of raw material used. For example, some manufacturers use a combination of bovine and porcine. The former makes the capsule firm, and the latter contributes to the clarity and plasticity of the capsules.
Most hard capsules available today are made of hard gelatin type. This is associated with various benefits that are mentioned below.
Hard capsules allow a degree of flexibility in filling and formulation that is not possible with tablets.
