Customer Reviews

  1. AWESOME! Review by lindarenee1964

    I have been taking the Probiotic Advantage for years now, and love it. But I wanted to give this new improved formula a chance, and have to say, I am thrilled with it. I have been suffering since 1997, and this week is the best I have felt in 13 years. My stomach actually feels normal..........I had forgotten what that feels like, to be honest. I would SO recommend this to anyone who has trouble with their stomachs..........from diarrhea, to constipation, to bloating and gas, and on and on..........this stuff is gold!!!!!!!!

10 billion probiotics for extra-strength digestive relief


Some digestive and regularity issues require “extra strength” support—which is where Probiotic Advantage Extra Strength comes in. To create it, Dr. David Williams began with ten of the most powerful strains of probiotics to boost your digestion and support your immune system and help with regularity—the same strains you get in Probiotic Advantage. But he increased the level of good, live bacteria to a 10 billion CFU (colony forming unit) dose.

Then he added Actazin™, a newly discovered green kiwi extract from New Zealand—which contains prebiotics, enzymes, and insoluble fiber. All of these “digestive boosters” work together to strengthen the probiotics—to give you extra strength support for healthy digestion, and enhanced or improved regularity.

Together, this powerful four-in-one solution gives you:

Prebiotics: to feed and strengthen the probiotics, boosting the level of digestive protection to give you more powerful relief.
Enzymes: to help your body break down protein, aiding healthy digestion.
Insoluble Fiber: to fortify the probiotics and keep them moving through your system.
10 Billion CFU’s of Good Bacteria: for better digestion, regularity, and immune support.

Plus, the new controlled-released tablets give you all-day support!


To create Probiotic Advantage Extra Strength, Dr. Williams used a special technology called BIO-tract™ to create a tablet that protects the good bacteria and helps each of the ingredients in this formula get to the right place in your gut for maximum effectiveness. When the tablet comes into contact with the moisture in your mouth, it becomes a fully-sealed gel, making it easy to swallow.

Plus, this new tablet is controlled release—slowly dissolving as it moves along your intestinal wall. So not only are you getting “extra strength” support, you’re getting all-day relief. From the time you take it in the morning, it keeps working to give you better digestion and regularity.

If you have chronic digestive issues, this is the formula for you. Dr. David Williams developed Probiotic Advantage Extra Strength so it contains 10 billion healthy, live bacteria in the 10 most powerful strains for advanced relief.

Dr. David Williams

Dr. David Williams has a hard-earned reputation as one of the world’s leading authorities on natural healing. Often years ahead of the conventional medical establishment, he has traveled worldwide to locate, evaluate and formulate supplements that work, and write about proven treatments and cures for practically every major health concern today.

Dr. Williams likes to recall that, when he was a kid, people were close and family was important. Since he was raised in a small, hard-working farm community in the Texas panhandle, most people didn't have a lot of the nicer things in life. But they did have something far more important than money; they had values. The people in his community relied on honesty and lived by the Golden Rule—they took care of each other.
Dosage: Take 1 controlled-release tablet every day prior to any meal.
