Digestion of any food was an uncomfortable process with a constant feeling of burning through my gut and stomach always feeling off. I love a coffee in the morning but it would cause serious discomfort and at least for the rest of the day. Since I take 2 of these every night however, within a week or two my stomach and gut feels calmed. Now after long-term use, I still eat healthily, fresh foods, low sugar etc, but can also enjoy a full life again coffee every morning, couple of glasses of wine, spicy foods, it's just amazing! They say your gut is your second brain, all health, even mood comes from there. This definitely feeds the right stuff. I ran out for a while and all the discomforts came back, I won't be without this now, a keeper for life! N.B You can take them anytime, they don't disrupt sleep and can be taken with or without food. Review: Suffer from acid reflux, GP prescribed Lansoprazole but low dose wasn't sufficient, higher dose I just wasn't comfortable taking. Did some research & found this instead, it works extremely well for me & been using it every day for about a year, no problems with the reflux. I take one after main meal in the evening, sometimes 1 after lunch but not often as lunch is a much lighter meal than the evening. ## Features - MAXIMUM STRENGTH 20 BILLION CFU SOURCE POWDER SACCHAROMYCES BOULARDII SUPPLEMENT: Saccharomyces Boulardii is an extremely well documented and proven strain of natural and safe yeast, which has been shown to reach the gut alive.

Did some research & found this instead, it works extremely well for me & been using it every day for about a year, no problems with the reflux. I take one after main meal in the evening, sometimes 1 after lunch but not often as lunch is a much lighter meal than the evening. ### ⭐⭐⭐⭐⭐ Review *by N***R on 21 August 2020* I normally take a probio complex which is comprised of six different types of bacteria. The main one being Lactobacillus Acidophilus which is particularly good at combatting the dreaded candida or yeast overgrowth. However, candida can build up a resistance to just about anything making it difficult to control particularly if you have been on antibiotics which kills off all the good stomach bugs. That’s why I have changed to Saccharomyces Boulardii which is related to baker’s yeast to help prevent the bad stomach bugs building up a resistance, after taking these for a while I will probably switch back again. In tests, S. Boulardii has been shown to secrete caproic, caprylic, and capric acid, these are fatty acids also found in coconut oil. Interestingly, by comparison with an S. Boulardii extract the most effective compound was capric acid in reducing candidal adhesion and biofilm formation although it was three times less effective. ## Frequently Bought Together - Natures Zest High Strength Saccharomyces Boulardii 20 Billion CFU with Prebiotics 120 Capsules Friendly Bacteria Probiotic Yeast Supplement, Vegan & Gluten Free, up to 4 Month’s Supply - Bio Cultures Complex Probiotics & Prebiotics - 60 Billion CFU - 2 Months Supply - 120 Capsules - 20 Live Bio Cultures - Lactobacillus & Bifidobacterium Strains - Vegan Probiotic Complex 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/462577669-high-strength-saccharomyces-boulardii-20-billion-cfu-with-prebiotics-120](https://www.desertcart.us/products/462577669-high-strength-saccharomyces-boulardii-20-billion-cfu-with-prebiotics-120) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-22*
