In this episode of The Ingredientsage Podcast, we take you inside the often-overlooked engineering behind vitamin capsules and explain why capsule design plays a critical role in safety, stability, and bioavailability.
From capsule materials and manufacturing methods to disintegration timing and moisture control, we break down what goes into a capsule long before it reaches a supplement bottle.
You’ll learn the differences between gelatin, HPMC, pullulan, and delayed-release capsules; how capsule selection affects ingredient compatibility; and why factors like oxygen transmission, hygroscopic actives, and fill weight precision matter.
We also discuss common capsule failures, testing standards, and how smart capsule engineering supports consistent dosing and regulatory compliance.
Whether you’re formulating supplements or reading labels more critically, this episode reveals the science and systems inside every capsule you consume.
Because understanding ingredients is the first step toward building better wellness.
