Now that you have the perfect formula to add to your product line, what solid dosage delivery form should you choose? Capsules, tablets, softgels or powder? The answer—it depends! This is a decision every brand marketer must make during product design. Each delivery form has its place in the dietary supplement arena. Several factors should be considered when selecting a delivery form to ensure the ingredients are delivered to the body in the most befitting form and the product is convenient and user friendly.
The two-piece hard-shell capsule is the most common delivery form in the supplement space. Most allow a rapid release and require fewer processing aids. Tablets are also widely used, which can be packed with a larger quantity of ingredients, allow time-release delivery and offer a variety of shapes and sizes. A softgel typically consists of a soft gelatin or vegetarian-based shell surrounding a liquid fill. This delivery form is particularly suitable for oil-based ingredients. Powders, as the name implies, consist of a single ingredient or mixture of ingredients in powder form.

These solid dosage delivery forms have specific manufacturing processes as well as advantages and disadvantages in form and function.
