Oregon Cranberry Extract (Cranberex)
Our cranberry extract is sourced from Oregon cranberry bogs, where the unique growing conditions of the Pacific Northwest produce berries with exceptionally high concentrations of proanthocyanidins (PACs). These specialized compounds help prevent bacteria from adhering to urinary tract walls - the first critical step in maintaining urinary tract health.* At 36mg PACs per serving, UrinaGuard delivers the precise dosage shown effective in clinical research.*
D-Mannose
D-Mannose works through a different mechanism than cranberry. This naturally occurring sugar binds to E-Coli bacteria (responsible for up to 90% of urinary concerns), creating a complex that is easily flushed from the urinary system during normal urination. The 1 gram dose in UrinaGuard represents the full therapeutic amount shown in effective in clinical trials* - unlike many competing products that provide suboptimal levels.
Standardized Green Tea Extract (400mg)
Our Green Tea Extract delivers antioxidant polyphenols that support the health of urinary tract tissues.* These compounds work in harmony with the additional ingredients to help maintain the integrity of this delicate system.* The 400 mg dose was selected based on research showing optimal urinary tract support at this level.
Why Choose UrinaGuard
Most urinary tract products either provide inadequate levels of active ingredients or take a single-ingredient, single-approach strategy. UrinaGuard supports urinary tract health with 3 different approaches at full clinical dosages of Cranberex® Cranberry Extract, D-Mannose and Green Tea Extract in one single, easy-to-take formula.
