What keeps the stomach acids from digesting the probiotics we take? Do the enteric coated really work?

Question

It seems that the powdered and encapsulated probiotics would be digested before the bacteria made it into the small intestine. What is the best delivery method to ensure the live bacteria make it to a point where they can survive? Would a colonic with the live bacteria be helpful or harmful? Do the enteric coated probiotics really work? What keeps them from passing entirely through the digestive system? Is this too much for one question?
Thanks for your answers in advance.

Answer 1

There is one product that guarantees that the probiotics get to the intestines live - all natural Optiflora - This is a patented process.

This two-product system uses new technology to protect beneficial microflora during the rigors of shipping, storage, and the acidic journey through your stomach. Other products claim live microflora at the time of manufacture. Optiflora guarantees the delivery of live microflora (500 million) to your intestines and colon. The colon plays such an critical role to our overall health and getting the probiotic there live is the only way for us to see the real benefit.

This two-product system includes Probiotic (Bifidus & Acidophilus...microflora) + Prebiotic (FOS...food source for microflora).

Patented triple encapsulation uses only natural ingredients to protect microflora until they are released in the intestine.

Seamless outer shell protects microflora against stomach acid.

Middle layer protects against oxygen and moisture.

Inner core holds & protects microflora until they are released in intestine.

No artificial flavors, sweeteners, colors or preservatives and no refrigeration necessary.

It truly is a great supplement and I use it regularly.

Hope this helpful and feel free to contact me with questions.

Answer 2

SOME bacteria are resistant to stomach acid. Many probiotics are selected for that ability. Enteric coatings would also be a potential protective mechanism. Once viable bacteria reach the colon, they colonize it and reproduce, thus maintaining a presence.
(Yes, that's a lot for one question!)
