The medical industry began using capsules in 1968 as an alternative to tablets. Hard-shelled capsules are the most famous type of capsule. These capsules often contain dry powdered components. These capsules are divided into two halves. The smaller "body" is filled with the contents and sealed using a larger cap.
What is the source of capsules?
The capsule manufacturing companies make capsules with gelling agents such as gelatin or plant derivatives. Gelatin is created by boiling down parts of cattle. After boiling down the bones, hoofs, and connective tissue, cold water is used to cool it and allow it to expand in cool temperatures. After the process is completed, the remaining substance is tasteless, odorless, and colorless. This can then be made into gel capsules which are used every day by consumers.

How are capsules made?
Pure NSM has two capsule-making machines at the Supplement Factory. One is semi-automatic and one is fully automated.
A semi-automatic machine is used in conjunction with a human worker. Factory associates place capsule shells inside a capsule plate according to the size of the capsule being made. The powders are then sucked into the machine. Before the caps of the capsules are placed on each capsule, the machine presses on. The plate is removed and the capsules are packed into bags.
