D-Mannose Tablets is a urinary support supplement that may be helpful for recurrent UTI. 1 Full Gram of D-Mannose / Tablet. D-Mannose is a naturally occurring sugar, found in some plants and fruits. Research has shown that D-Mannose may provide urinary tract support by inhibiting the attachment of E. coli bacteria to the urinary tract. How D-Mannose works: Studies outside the body (in vitro) have demonstrated that E. coli may bind to D-Mannose molecules, rather than binding to the bladder wall. The free-floating molecules may then be flushed from the urinary tract during urination. Proudly Packaged, Manufactured AND Sourced in the USA.
