Unfortunately the cost means I cannot continue and have looked for other avenues to help her. ### ⭐⭐⭐⭐⭐ Wouldn’t be without it. *by on Reviewed in the United Kingdom 15 January 2026* I’ve had my tb x welsh D mare on this stuff for two years, she’s just turned 20- still acts like a 4 year old and never has many issues since she’s been on it. Have used the gut balancer when needed but this stuff in her regular feed keeps her as bouncy as a ping pong ball. (It doesn’t heat the horse up, mine just happens to act like Micheal Flatley on speed every waking minute regardless). I don’t use any other supplements and won’t need to with this in her diet. ### ⭐⭐⭐⭐⭐ Excellent product *by on Reviewed in the United Kingdom 15 November 2021* Love this. My horsecis doing so well.Keeps her in tip top condition ## Frequently Bought Together - Protexin Equine Premium Fifteen Plus 900g - Supplement for Older Horses, For Gut, Immune, and Joint Support - Protexin Equine Premium Gut Balancer 700 g - Protexin Equine Premium Acid Ease, 3 Kg, FE1016 --- ## 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/165360597-fifteen-plus-900g-supplement-for-older-horses-for-gut-immune](https://www.desertcart.us/products/165360597-fifteen-plus-900g-supplement-for-older-horses-for-gut-immune) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-18*
