Product Description

WHAT IS UDO’S CHOICE ADULT’S PROBIOTIC? Part of our multiple award-winning collection of age-specific probiotics, Udo’s Choice Adult’s Probiotic is a medicinal blend of six human-adapted (aka resident or non-transient), adult-specific live probiotics. This special blend provides you with a safe and effective high-potency source of probiotics that naturally live and thrive in the healthy digestive tract of adults.

WHAT ARE PROBIOTICS AND WHAT DO THEY DO? The human body is a walking ecosystem: There are ten times more microbial cells living on the surfaces of our bodies — both inner and outer — than there are human cells.(1) Also known as ‘friendly’ bacteria, the probiotics that live in our digestive tract protect us from harmful bacteria. In addition, they help with digestion; make vitamins (B and K) and short chain fatty acids; stimulate the protective ‘mucin’ secretion in the gut lining; and break down cholesterol and toxins in our bowel. But their wide-ranging health effects extend beyond our GI tract, affecting our immune system, the liver and brain, the weight management system, and more.(2) Our very survival depends on them.

WHY ARE PROBIOTIC SUPPLEMENTS IMPORTANT FOR HEALTH? Throughout the human life cycle, the GI tract microbiome usually maintains a mutually beneficial relationship with its host. However, many factors can reduce and negatively affect the number of friendly bacteria in the adult gut: infection and other illness; antibiotics; aging; cooked and hyper-processed foods; stress; a fiber-poor diet; alcohol or chlorinated water, inadequate sleep, and taking NSAIDs and other medications, to name some.(3)

A reduced number of beneficial bacteria leaves you vulnerable to harmful bacteria that can overpopulate, creating an unbalanced state known as intestinal dysbiosis. Left untreated, symptoms of dysbiosis can become chronic and lead to bigger health concerns.(4) By restoring a disrupted gut balance, probiotic supplements keep various ‘bad’ bacteria in check and promote the functional state of the GI tract and its far-reaching metabolic, immunological, nutritional, and psychological effects.*(5-9)

WHAT MAKES UDO’S CHOICE ADULT’S PROBIOTIC SO SPECIAL? Our pioneering work with our Udo’s Choice probiotic blends started in the 1990s when we introduced the first-ever line of age-specific probiotics. Because we care about results, we tailored this high-potency formula to the specific needs of adults, since the types and amounts of probiotics found in a healthy gut change over the life cycle. And, like people, probiotics work better in teams, which is why we chose to use blends of strains.

All of our Udo’s Choice probiotics are human-adapted (or HA). Unlike the transient (aka non-resident) dairy- and plant-derived bacteria widely marketed, our HA probiotic strains successfully implant and colonize the human digestive tract for a longer period of time. Why? HA strains survive strong stomach acid and bile, reaching the intestinal tract at a better rate. Transient probiotics are far less effective.

Udo’s Choice probiotics deliver: When compared to four other well-known brands by an independent research group, the measured viable cells of Udo’s Choice ‘stood out from the rest numerically and statistically’, and ‘Udo’s Choice was the only brand for which the number of viable bacteria recovered met the recommendations for daily dosage of a probiotic regimen’.(10) No other company makes probiotics like we do.

19-54 years old


Minimum 17 billion viable cells per capsule at manufacture; 10 billion at date of expiry.


Udo’s Choice® Adult’s Probiotic blend contains the following human-adapted probiotic strains: Lactobacillus casei HA-108 (35%); Lactobacillus rhamnosus HA-111 (25%); Lactobacilius acidophilus HA-122 (20%); Lactobacillus plantarum HA-119 (10%); Bifidobacterium bifidum HA-132 (5%); Bifidobacterium breve HA-129 (5%). Non-medicinal ingredients: potato starch, silicon dioxide (to keep dry/ prevent damage to probiotics), ascorbic acid (as an antioxidant), stearic acid and hydroxypropyl methylcellulose. Encapsulated in plant-based capsules.


Take 1-3 capsules daily, with or after meals. For best results: Open the contents of one capsule into food cool enough to eat, to ensure a continuing supply – starting in the mouth – of protective probiotics in every meal. We do this to mimic how it was in nature, when diets were rich in fresh foods covered with probiotics, before we started to kill them by cooking, processing, chemical farming practices, etc. Mixed into foods, probiotics benefit your entire digestive tract – including mouth, esophagus, and stomach – that swallowing capsules will miss.


Always keep refrigerated. At your local health food store or supermarket, you will always find it in the cooler. Refrigeration ensures maximum potency and stability of live bacterial cells, and guarantees number of cells listed at date of expiration on the label. Freeze to increase stability and prolong potency. For each day without refrigeration (at room temperature), about 1% of the viable cells will be lost.

  1. Meg

    My favorite brand of probiotic. The capsules aren’t ginormous (about the size of a Tylenol capsule). Has the most active strands in comparison to other brands I’ve used. Must be refrigerated.

  2. B. Fisher

    I have tried many different probiotics, and all seem to work well at first, but these are the only ones that have seemed to work for me long term, I take them daily and they drastically improve my digestion and mood, I love the difference… My friends grandmother swore by this brand and used them long term she is 90 and in great condition, so I will stick with her advice and stop trying all these other brands 🙂 Thanks for the consistent quality product

  3. Lisa Marie

    Udo’s really appears to be working out my digestive issues. I have tried many

  4. C. Vitosky

    Can’t live without.

  5. Krista F

    Excellent quality and quantity of probiotics! I’ve been taking these for a while now and they help so much!

  6. Michelle B.

    After being on a few rounds of antibiotics, I began taking this product and it helped restore the good flora in my stomach. I still developed a yeast infection so I doubled up on the dosage and the yeast left rather quickly. Great product and great price! Super fast shipping as well!

  7. Jesper Juhl Olesen

    Since 2005 I have been using Udo’s Choice oil, a product I’ve been a big fan of throughout the years.
    A few weeks ago, I bought their “Adult’s Probiotic” for the first time, after the owner of our local natural health store (in a small town in Denmark) made a recommendation to try this product.
    He explained the difference in quality between the various types of probiotics and I have already noticed a remarkable difference in the stomach region.
    So despite the fact that this was the highest priced brand on the shelf (in the fridge) I am already a loyal user!

    Thanks to the Udo’s Choice company for making another truly great product!

  8. J. Ryno

    Probably the highest quality pro-biotic out there. I only trust live cells that need refrigerated.

  9. JoJo

    Love getting my health in order and this Udo’s probiotic is great for making sure I get all that I need for my health needs. I only take one before breakfast and feel the difference after.

  10. Anil Kay

    I have a very good “gut” feeling now – pun intended ;o). A lot of improvement in overall health after I started taking it. Would definitely recommend it.

  11. Jojo

    Love getting my health in order and this Udo’s probiotic is great for making sure I get all that I need for my health needs. I only take one before breakfast and feel the difference after.

  12. sheila armlin

    Took these after three surgeries to repair my gut flora from all the antibiotic they put in me.

  13. Natia

    Besides good CFU and strain count, I really like that this product comes in a dark GLASS bottle. Capsules are small in size and easy to swallow. Remember to keep your probiotics REFRIGERATED for maximum potency. Mine arrived with a COLD PACK in the box.

  14. Kerri

    Love this probiotic! **Keep in the refrigerator for longevity

  15. Cynthia

    Great product.

The Bottom Line

A diminished number of probiotics in the gut can wreak havoc on our digestive and overall health. Taking a high-potency blend of probiotics — specifically human-adapted probiotics — is a safe and effective means for maintaining and restoring the various beneficial bacteria that naturally thrive in a healthy digestive tract. We created Udo’s Choice Adult’s Probiotic to give you all the ‘friendly’ bacteria you need, and provide additional protection from the harmful ones.*
