Pullulan Capsules

What Are Pullulan Capsules?
Pullulan capsules are 100% plant-based, two-piece hard shells used for premium dietary supplements and pharmaceutical products. Unlike gelatin and HPMC, pullulan is a naturally derived polysaccharide produced through the fermentation of plant-based starches like tapioca or corn. This unique origin makes it the only capsule material eligible for USDA Organic certification.
Naturally crystal-clear and transparent, pullulan capsules offer a far better oxygen barrier than gelatin and HPMC capsules. As a result, they are widely used in premium clean-label formulations. The specialized fermentation process and higher production costs make them one of the most expensive capsule options on the market.

Recommended Uses & Key Considerations
Not every formulation requires pullulan capsules. Its premium positioning comes from a combination of plant-based origin, oxygen protection, and organic certification.
✔ Ideal Formulations
- Antioxidants & functional nutrients: Vitamin C, CoQ10, carotenoids, vitamin K2, and astaxanthin.
- Probiotic & microbial products: Probiotic blends, postbiotics, digestive enzymes, and other biologically active ingredients.
- High-value botanical supplements: Turmeric extracts, green tea extracts, premium Ginseng root powders, and saffron extract powders.
- Organic & whole-food products: Certified organic mushroom extracts, freeze-dried greens, maca root powder, and cold-pressed organic berry blends.
⚠ Factors to Consider
- Highly hygroscopic ingredients: Water-seeking powders may absorb moisture from the capsule shell over time. This can lead to shell brittleness.
- Water-based liquids: Pullulan is completely water-soluble. Any liquid formula containing water or glycerin will rapidly dissolve the pullulan shell.
- Value-oriented products: Pullulan capsules command a premium price. If you’re producing standard pharmaceutical or supplement products, gelatin or HPMC capsules may be a more economical choice.
