I take it regularly just to keep me balanced now. ### ⭐⭐⭐⭐ Subtilis? *by N***B on June 18, 2026* Love the brand, but experienced difficulties acquiring Subtilis. Ordered, but was sent Coagulans with a "Subtilus" Amazon bar-code sticker on it. Requested and received refund and told to reorder. Same thing happened a second time, ...and a third, ...and a fourth. Alway received Coagulans, despite every Amazon representative promising they'd corrected the problem. This appeared to be an Amazon problem, not a Natural Foundation problem, so... Wrote the company seeking clarification and an actual bottle of Subtilis, along with asking which strain of Subtilis (which wasn't provided in the listing at that time). Natural Foundation's sent boilerplate "pound-sand" response to both questions. If Natural Foundation reads this, more research was done on this subject, because Subtilis MB40 is a potentially life-saving strain, which Deerland produces under an apparently trademarked name, DE111. ADM owns Deerland and viciously protects their Intellectual- property, which terrifies everyone, including apparently, Natural Foundation. However, ADM does not own Subtilis MB40, because it is a naturally occurring probiotic and can't be patented. Presumably, ADM threatened everyone in the industry and nobody wants to spend years in court fighting a bully like ADM (even though ADM has no legal claim to MB40). That doesn't help people who need Subtilis MB40 (which kills the dreaded Staph-Aureus, Osteomyelitus, bone-infection crippling millions around the world. Virtually every paralyzed person and most type2-diabetics who lose limbs, lose them to Staph-Aureus. Staph, which eventually turns into MRSA (Antibiotic-Resistant flesh-eating bacteria). Resistant to Antibiotics, but not resistant to Subtilis MB40. Implore Natural Foundations to produce Subtilis MB40? It'll save limbs and lives. And let buyers know if and when Amazon begins shipping Subtilis MS31 and not sticker'd-over Coagulans? ## Frequently Bought Together - Lactobacillus Plantarum Probiotic Supplement 240 Tablets 3 Billion CFU Probiotics for Men & Women Supports Intestinal Digestive & Gut Health Made in The USA (240, Lactobacillus Plantarum) - Vitamatic Lactobacillus Plantarum - 20 Billion per DR Capsule - 60 Count - Digestive Support - Made with Prebiotic Inulin Fiber - Vitamatic Bacillus Subtilis 10 Billion per DR Capsule - 60 Count - Digestive, Gut & Immune Health Support - Made with Prebiotic Inulin Fiber --- ## 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.is/products/652579153-bacillus-subtilis-probiotic-240-tablets-4-month-supply-researched-strain](https://www.desertcart.is/products/652579153-bacillus-subtilis-probiotic-240-tablets-4-month-supply-researched-strain) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-09-02*
