## Overview

Cutting Edge Cultures LR Superfood Starter delivers a pure, lab-verified L. reuteri probiotic culture that ferments slowly over 36 hours to produce exceptionally high CFU counts—over 67 billion per half-cup serving. Designed for reuse, one box can yield up to 80 quarts of cultured dairy or non-dairy foods, making it a cost-effective, sustainable choice. Non-GMO, vegan-friendly, and crafted in the USA, this starter culture supports serious gut health enthusiasts seeking real results beyond typical yogurt blends.

## Description

Important: Not All “L. Reuteri” Starters Are the Same Many products labeled “L. reuteri” are actually blended yogurt starters that contain multiple fast-growing bacterial strains. In these blends, L. reuteri does not dominate and is quickly outcompeted during fermentation, leaving little (if any) L. reuteri in the final result. LR Superfood is different. It is made with pure L. reuteri only, specifically designed for extended, low-temperature fermentation so this unique strain can truly thrive. If you’re seeking the real benefits associated with L. reuteri, purity and process matter. What Makes LR Superfood Different Most yogurt cultures are designed for speed, not potency. They ferment quickly but limit bacterial growth. LR Superfood is different. It uses a low-and-slow fermentation process, allowing L. reuteri to multiply extensively over time and reach meaningful levels in the finished food. Not all “L. reuteri” products are created to deliver meaningful results. Lab-Verified Potency in the Finished Food Independent lab testing of the finished cultured dairy confirms 67+ billion live L. reuteri per half-cup serving. Each prepared batch contains approximately 560+ billion live cultures, and a full box can produce over 2.2 trillion live cultures from initial batches alone. With continued reculturing, a single pack can generate tens of trillions of live L. reuteri over time, far exceeding what is typically obtained from probiotic capsules or blended yogurt starters. Designed for Reuse and Long-Term Value Unlike one-time-use starters that must be repurchased each batch, LR Superfood is designed to be recultured again and again, dramatically reducing cost per batch. One box can yield up to approximately 80 quarts of cultured food over time, making it an exceptionally economical option for long-term use. Real cultures grow; disposable ones do not. Results, Not Just Yogurt This product is designed for people who want meaningful results, not just flavor or convenience. It supports maximizing L. reuteri intake using a proven fermentation method trusted by health-focused users. Crafted in the USA using carefully selected strains to ensure consistency, purity, and performance. Non-GMO. Vegan and Dairy-Free Friendly The culture itself is 100% vegan and dairy-free and can be used with dairy or non-dairy milks. Step-by-step instructions for both methods are included. For best results, we recommend pairing with Cutting Edge Prebio Plus, which provides the prebiotic fiber L. reuteri needs to thrive and develop optimal texture. Important Note Results depend on fermentation conditions and adherence to instructions.

Review: MUCH LESS NEEDED - I used one packet in 1 Gallon of 2% Milk The milk was heated in a crock pot to 180 degrees When cooled to 100F the ONE packet was added and the milk was fermented in a box with a heating pad for 36 hours. The temperature of the milk ranged from 108 to 90ish yet produced satisfactory results. Approx one half whey and one half casein (Greek Yogurt) when filtered through a fine filter mesh. Taste wise...the whey has a mildly pleasant taste so i mixed it with xanthan gum and fruit into a smoothie. The Greek Yogurt is creamy even with 2% Milk and also carries a mild taste so it takes fruit or Vanilla Extract pretty well. Haven't had a chance to add this to another gallon yet but have little doubt it will ferment this as the culture is pretty aggressive and seems resilient during my careless incubation cycle. Save the other 3 packets for a rainy day since only 1/4 their recommended inoculation was more than sufficient to obtain pretty satisfactory results BTW I added a1/4 cup Corn Syrup to the milk prior to fermenting and did not add any inulin but still achieved satisfactory results. The corn syrup was added as a little booster for the culture but probably not necessary since the bacterium feeds mostly on lactose in the milk itself. All in all pretty good results for my amateurish efforts
Review: Great Product - Great product. I’d purchase again.

## Questions & Answers

**Q: What strains of l.reuteri are used in this starter?**
A: How do you you use Dr. Davis’s name when he is specifically recommending the strain ATCC PTA 6475.
The L-Reuteri strain you sell is SD- 5865?

**Q: Since this product has to remain refrigerated how is it shipped to maintain proper temperature?**
A: Mine was shipped in a padded envelope, no ice pack. I was watching for it so it didn't sit in a hot mailbox all day. I have cultured it and it was highly active and did fine.

**Q: Can I use this product  to make kifer?**
A: Cutting Edge Cultures makes two products specifically for kefir. The Easy Kefir Starter, and the Kefir Soda Starter are both available from The Raw Diet Health Shop. They are stored in a refrigerator to keep cool. Amazon does not store these in the refrigerator.

**Q: Is prebiotic fiber mentioned in the instructions necessary to make the yogurt**
A: The prebiotic fiber is food for the L. Reuteri bacteria. To get the most healthy fermented dairy, it’s important to provide the inulin fiber. I don’t make L Reuteri

### ⭐⭐⭐⭐⭐ Great Product
*by M***D on January 7, 2026*

Great product. I’d purchase again.

### ⭐⭐⭐⭐⭐ Makes delicious thick and creamy yogurt
*by F***S on August 10, 2025*

This makes a really good tasting yogurt. The probiotics are packaged well and are very active. I am able to make at least 5 batches of yogurt per packet. I have not tried beyond that because I do not want to weaken the efficacy of the strain. The yogurt seems a little more runny on the 5th batch. This product works well in a yogurt maker, it produces a very thick rich and tangy yogurt that is very pleasant on its own. I can tell a difference in my mood and my digestion. I also use L gasseri strain in conjunction with this L reuteri. I do find that it feels kind of pricey but I do get quite a few innoculations out of it. Amazon does make sure that you get the product quickly. Be sure to refrigerate it once it arrives!
