Excipients
Excipients are inactive ingredients used in making medicines and supplements. Think of them as the supporting cast that helps the main active drug (the star) perform better. They serve various purposes like helping pills hold their shape, making liquid medicines mix properly, or ensuring drugs stay fresh longer. When you see a tablet, the actual medicine might be just a small part of it - the rest is made up of excipients. These ingredients are crucial in pharmaceutical manufacturing, similar to how ingredients like flour and eggs are essential in baking, even though they're not the main flavor.
