    • 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. 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

    2. 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

    3. 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

    4. 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



    6. 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

    7. 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
