Pros/cons?** A: I think nattokinase has prevented more blood clots in my legs. However, I switched some time ago to the NOW brand, which I am convinced is just as effective as Allergy Research's product, and much cheaper. But since then, I also stopped using the NOW nattokinase and switched to Dr. Frank Shallenbergers' Circutol, which contains 50 mg of nattokinase, but is more effective than nattokinase by itself, Shallenberger claims. I put a lot of faith in him because he introduced prolozone therapy (ozone injections) in this country, as far as I can tell, and it has proven quite salutary for me. **Q: Is this interact form?** A: I'm not sure what you mean by that question. I took nattokinase from Allergy Research Group for several years before discovering that I could save a lot of money with a different brand. I chose the reputable NOW brand, which serves me every bit as well. ARG is the brand used by researchers, but I'm not a researcher, and don't feel the need for anything that refined. I began taking nattokinase after experiencing four blood clots in my legs over a period of about 12 years, and haven't had any clots for about eight years now. **Q: What is the expiration date?** A: No expiration date but you can contact allergyresearchgroup.comor call 510 263 2000. not sure why not expiration date ## Frequently Bought Together - Allergy Research Group - Nattokinase Supplement NSK-SD 2000 FU, 100mg - Cardiovascular/Circulatory Health - 180 Softgels - Calroy Health Sciences Arterosil HP Professional - Endothelial Glycocalyx Support - Heart Health Support - Artery Health Support - Circulation Support – MonitumRS® Rhamnan Sulfate - Monostroma Nitidum - Allergy Research Group Lumbrokinase Supplement - Circulatory System Support, Supports Blood Circulation Already in The Normal Range - 60 Delayed Release Vegetarian 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.us/products/3159322-arg-nattokinase-100-mg-circulation-support-180-capsules](https://www.desertcart.us/products/3159322-arg-nattokinase-100-mg-circulation-support-180-capsules) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-19*
