Bifido-Plus 90c is available by Progressive Labs.
The micro-organisms in Bifido-Plus are natural inhabitants of the intestinal tract. Bifido-bacteria live mainly in the colon while lacto-bacilli inhabit the small intestines. As much as 98% of the fragile, living organisms in many powders, liquids and capsules are destroyed by harsh stomach acids before they reach the lower intestinal tract.
Bifido Plus is acid restiant and heat tolerant to allow the product to pass through stomach acids intact to deliver maximum potency to the lower intestinal tract where it is needed to restore and/or maintain a balance of healthful organisms and inhibit the growth of pathogenic organisms.
