Carrageenan is a natural substance derived from red seaweed. It is widely used in supplement capsule shells as a plant-based alternative to gelatin. Its primary function is to give capsule structure and stability without relying on animal products, making it ideal for vegetarian and vegan supplements.
Some concerns about carrageenan arise from confusion between two forms: undegraded carrageenan, which is safe, and degraded carrageenan (poligeenan), linked to potential health risks. Importantly, only the safe, undegraded form is used in food and supplements.
Why Is Carrageenan Safe?
Regulatory bodies like the FDA and EFSA confirm that undegraded carrageenan is safe for use in food and supplements. It has undergone extensive testing and has been cleared for use within acceptable limits. The concerns often stem from studies on degraded carrageenan, which is not allowed in consumable products.
Misconceptions About Carrageenan
The confusion between degraded and undegraded carrageenan has led to some misconceptions about its safety. Degraded carrageenan, also known as poligeenan, has been linked to inflammation and other health issues in animal studies. However, poligeenan is not used in supplements. The form used in softgels and food products is undegraded carrageenan, which does not exhibit the same risks and is widely regarded as safe.
Why Is Carrageenan Used in Capsule Shells?
Carrageenan is used because it provides a reliable, stable structure for softgel capsules. Unlike gelatin, which is derived from animal sources, carrageenan is plant-based, offering a vegan-friendly alternative. It helps to preserve the integrity of the capsule and ensure that the supplement is delivered effectively.
Conclusion
Carrageenan is a safe, natural alternative to gelatin, approved by regulators, and used in countless products. By choosing carrageenan-based capsules, manufacturers can cater to the growing demand for plant-based supplements without compromising on quality or safety.
Understanding the difference between safe, food-grade carrageenan and problematic poligeenan is essential for dispelling myths and providing consumers with accurate information.
