    Doctor Recommended Probiotic - Prebiotic Blend

    620mg per capsule, available in bottles of 60 or 90 capsules ~ 1 or 2 capsules per serving

    New look, same great probiotic!

    A few years ago, Safer Medical, the manufacturer of Prescript-Assist, allowed Enviromedica to take over the marketing and distribution of their popular soil-based probiotic. Recently, Safer Medical of Montana decided to bring the marketing and distribution back in house. They had to change the packaging because the previous packaging look was created by Enviromedica. We get our Prescript-Assist from the manufacturer and are now carrying the bottles with the new look. The formula is the same, only the packaging is different. 

    What Is Prescript-Assist?

    Prescript-Assist is a powerful blend of probiotics and prebiotics with 65 million soil-based microorganisms in each 620 mg capsule. This broad spectrum probiotic is recommended by doctors for a variety of digestive concerns and other gastrointestinal diseases.

    Backed By Research

    The gold standard for a solid scientific study is one that is double-blind, placebo controlled, and peer-reviewed. A published trial adhering to these standards found that Prescript-Assist can:

    • Keep the gastrointestinal tract healthy
    • Restore healthy microorganisms in the gastrointestinal tract
    • Ease abdominal discomfort, nausea, and indigestion
    • Regulate bowel patterns
    • Decrease bloating and flatulence
    • Promote overall health

    Why is Prescript-Assist the best probiotic?

    Prescript-Assist is a probiotic/prebiotic blend that is backed by five years of double-blind university clinical trials. These laboratory studies concluded that the probiotic/prebiotic blend found in Prescript-Assist outperformed all other probiotics on the market, including the popular lacto and bifido bateria. Prescript-Assist is gluten free, soy free, dairy free and yeast free. 

    Probiotics vs Prebiotics 

    Probiotics are bacteria and yeast found naturally occurring in the human gut. Modern medicine has embraced supplementing with probiotics for the treatment of many digestive disorders and GI illnesses. Doctors often recommend probiotics like Prescript-Assist to boost the immune system and maintain optimum health. 

    Prebiotics increase the number and the activity level of the beneficial microorganisms already established in the gut. Different prebiotics affect different microorganisms. 

    Prescript-Assist Shelf Life: 

    Prescript-Assist capsules retain at least 95% of their potency two years after their date of manufacture. Refrigeration is not required. 

    Prescript-Assist Dosage Instructions: 

    Take 1-2 620 mg capsules per day. Prescript-Assist can be taken alone or with food.

    1. Excellent product!

      I have used Prescript-Assist for several years. Unlike many other similar products, I never have a reaction to this one because it is so pure. And it makes a difference in my digestion and elimination. With Lyme and leaky gut, I find that this product gives me a better chance to heal. on

    2. Prescript-Assist

      Excellent product! Have been using it for several years. Very good to build healthy flora in the intestines. Very pure. I am often unable to use products because of their additives, but this one is great. Good for GAPS diet patients. on

    3. Really Made a Difference

      This product is one of the best probiotics on the market. Functional Medicine Practitioner, Chris Kresser, recommended it and it is the probiotic he prescribes to several of his patients. It's been very effective for my elimination problems. I don't want to be without. I also love how you don't have to refrigerate it. It's very stable under severe conditions of heat/cold. on

    4. Great product!

      I'm taking this based on Dr. Carolyn Dean's recommendation as the best probiotic out there. I have had no ill effects whatsoever, and believe it is helping round out the Completement Formula from Dr. Dean. Also, great customer service! on

    5. Best probiotic I've ever taken!

      I'm in my sixties and have taken many different brands and types of probiotics over the years. This is the only one I've ever taken that has had a significant, supportive effect. I notice a difference within 24-36 hours after taking it. on



    7. Great Option for Gut Health

      I've been taking this probiotic, Prescript Assist, for a full year now. It has healed my leaky gut issues, and resolved most of my bowel issues. I take one a day at the advice of my functional medicine doctor. I like that it doesn't have to be refrigerated, thus travels well. on

    8. good soil based probiotic

      I feel this is one of the better soil based probiotics out there. I take it every day and it keeps my gut healthy and keeps me healthy overall. I haven't been sick in years! on
