• Polyphenol extracts
• Essential oils
• Antioxidant complexes
• Lipid-sensitive nutrients
• Carotenoid formulations

Packaging Synergy Engineering

For oxidation-sensitive formulations, capsule technology alone is often insufficient.

Integrated stability systems may also include:

• Nitrogen flushing
• Oxygen absorbers
• High-barrier blister films
• UV-protective bottles
• Desiccant-integrated packaging

This combined engineering approach helps improve product stability throughout international shipping and commercial distribution.

Organic-Compliant Plant Capsules
