Gelatin capsules stay in good condition when you store them in the right environment. Heat, moisture, and direct sunlight can damage the capsules and affect their shape, strength, and performance. Always keep them in their original, tightly closed container. Store them in a cool, dry place with stable room temperature. Avoid places with high humidity, such as bathrooms or near kitchen sinks. If you follow the right storage steps, gelatin capsules can maintain their quality for a longer time.
