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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Curcumin Alternative to Systemic Pain Relief *by on Reviewed in the United States December 15, 2019* I purchased this as an alternative to Turmeric/Curcumin because I am limited in how much I can take without side effects. Also, I am allergic to NSAIDS but pain relievers are essential in treating my degenerative disc disease, RA, and polyneuropathy. I found Serracor-NK to be comparable to Curcumin in terms of pain relief and it doesn’t interfere w/ the effectiveness of my other medications. I take 1 pill at bedtime, which is easier to do on an empty stomach, as recommended by the manufacturer. Personally, I didn’t have any issues w/ the smell noted by others—I have a divided pill case and kept this, along w/ my fish oil separate, but still they didn’t bother me—and I tend to be hyper sensitive to smells. I didn’t have any negative side effects and will definitely reorder. Excellence Curcumin alternative! ### ⭐⭐⭐⭐⭐ This is one good product. *by on Reviewed in the United States June 12, 2019* Helps keep my blood pressure under control. It also keeps my inner ear pressure from building up by keeping the inner ear fluid thinned out so it will drain properly. Keeps congestion in chest from building . It also disolved what I believe was a blood clot that I had in my right leg for over 10 years. It took about 6 months when I first started taking Serracor-NK for it to completely go away. Besure to follow direction for it to work. ### ⭐⭐⭐⭐⭐ Works great on small cysts! *by on Reviewed in the United States March 14, 2023* i have been taking for a few weeks and noticed it has reduced a cyst on my elbow by 99%!!! The cyst is almost completely gone!!!! ## Frequently Bought Together - AST Enzymes Serracor-NK –Proteolytic Systemic Enzyme Formula – Contains Acid-Resistant Serrapeptase and Acid-Resistant Nattokinase – 90 Vegetarian Capsules - Serra-RX 80,000 SPU Serrapeptase - Acid-Resistant Proteolytic Systemic Enzyme, Non-GMO, Gluten Free, Vegan, Supports Sinus & Lung Health, 90 Veg Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/50562835-ast-enzymes-serracor-nk-proteolytic-systemic-enzyme-formula-contains-acid](https://www.desertcart.sn/products/50562835-ast-enzymes-serracor-nk-proteolytic-systemic-enzyme-formula-contains-acid) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-25*
