## Questions & Answers

**Q: What is the actual amount of Serrapeptase and Nattokinase in this supplement?**
A: I don’t know exactly but my family and I have used this brand for years. We take as directed on the bottle. Bulk Supplements sells the powder form you can measure out but they are sold separately.

**Q: Nattokinase is an enzyme found in nattō, a Japanese breakfast dish made of fermented soybeans. so Is it really soy free?**
A: Hello! Though nattokinase is an enzyme derived from fermented soybeans, it has been isolated to ensure safety and purity. Extra microfiltration steps in the manufacturing process leave no functional soy or microorganism particles available for human consumption. Customers with soy allergies should not be deterred from products with nattokinase as the finished product does not contain added soy. It is, of course, always advisable to monitor oneself for any reaction if allergies are severe.

**Q: Why isn't the serracor-nk blend listed on this bottle? the other bottle i looked at has 500 mg listed on it.**
A: When it comes to enzymes, the most important level of measurement is the activity level. There are 15,000 FU in Serracor-NK.

**Q: "We do not disclose amounts of serrapeptase and nattokinase in Serracor-NK since it is a proprietary blend." Seems shady?**
A: Let me put your mind at ease. We do have a case study on Serracor-NK and it has been on the market for over 10 years. You can see on the reviews on how it has helped people.
