    The first reason I was drawn to Probiotic Advantage was the very small size of the caplets. I take two each morning before I eat. I am very pleased with the results, including the peace of mind with probiotics. I am aware of the need for everyone to use probiotics and it is one type of supplement that I would never do without. Also the price is reasonable, especially compared to many others. I trust Dr. Williams' opinions and products. He has been years ahead of many others in his reports and findings regarding health issues. Thanks Doc.

Probiotic Advantage is a supplement for everyday digestive relief

  • Helps ease occasional constipation and diarrhea
  • Relieves flatulence and uncomfortable gas
  • Promotes better nutrient absorption
  • Supports your immune system
  • Improves the breakdown of foods

Probiotic Advantage is like a multivitamin for your digestive system. Nurturing the delicate balance of beneficial bacteria in your digestive tract is absolutely critical for optimal health—critical, in fact, for life at all. Everyone should be taking a supplement for digestive relief, even if you don't have digestion concerns. It's cheap daily insurance!


They are delivered throughout your digestive tract--guaranteed. The patented BIO-tract® delivery system slowly releases the probiotics for all-day digestive relief. And special LiveBac® technology keeps the bacteria alive so they safely get to your intestines where they are needed to ease gas, bloating, and occasional constipation.

Many probiotic supplements only guarantee that the bacteria are live at the time of manufacturing—but won’t guarantee that the delicate bacteria survive all the way through bottling, delivery, and through the product’s expiration date.  Which means you could very well be taking probiotics that are dead—useless. Probiotic Advantage is guaranteed 100% potent with 2 billion live bacteria all the way through the expiration date clearly printed on the bottle.


Many digestive relief supplements contain just 1 or 2 strains of bacteria—giving you only partial coverage. But each Probiotic Advantage caplet gives you 7 extremely hardy, live probiotic strains, all backed by clinical research for more complete coverage.

  • L. fermentum: helps keep excess gas from forming and keeps uncomfortable bloating at bay.
  • L. acidophilus: helps form colonies of good bacteria to balance out the unwanted organisms in your gut and supports proper immune function. Plus, it helps reduce occasional diarrhea and supports vaginal health.
  • B. longum: plays a critical role in breaking down carbohydrates, and fighting free radicals.
  • B. bifidum: helps with the digestion of dairy products.
  • L. rhamnosus: helps improve vaginal and urinary health and reduces occurrences of traveler's diarrhea.
  • L. plantarum: produces hydrogen peroxide, which discourages growth of non-beneficial bacteria.
  • L. salivarius: has been shown to promote immune health.


PREBIOTICS help feed and strengthen these good bacteria.

The prebiotics "supercharge" the probiotics, so the good bacteria crowd out the bad bacteria. The specific type of prebiotics in Probiotic Advantage feed only the good bacteria—unlike ordinary prebiotics that feed both beneficial and non-beneficial good and bacteria in your gut.

Probiotics have always been a part of my core recommendations. I can't emphasize enough how important they are to your overall good health. And you'll feel the difference in your digestion with just one tiny caplet a day, I guarantee it.
