## Questions & Answers

**Q: how much serrapeptease is in this?**
A: Catherine,
Thank you very much for submitting your question.
Serracor-NK is a proprietary blend, and we do not disclose the activity levels of ingredients. The reason it is proprietary is because it was initially designed to be sold to doctors and therapists. Over the years, it became one of the most trusted products in the industry, and we decided to make them available online. One of the reasons for its popularity is that we enteric-coat serrapeptase in its powder form using a food-grade compound, which allows the enzyme to safely traverse harsh stomach environment without losing its potency. Most other companies place enzymes in thicker capsules or gel caps, which are unreliable or inefficient means of delivery. Some companies use phthalate to coat their product. Our products DO NOT use phthalates. Lastly, I like to point out that we have been producing enzymes in southern California since 1984, with a countless number of happy customers all over the world. If you like to know more about our products, please feel free to contact us at 1-800-608-1688, M-F 8:30-5:00 Pacific Time. We love to hear from our customers. Thank you for your patronage.

**Q: Where does the serrapeptase originate from?**
A: Silkworms

**Q: Is this product made with soybeans?**
A: Hello! The enzyme nattokinase in Serracor-NK is derived from fermented soybeans. However, once extracted it goes through a purification process and the finished product does not contain any soy.

**Q: Is this product gluten-free?**
A: Yes, Serracor-NK is gluten-free.
