If you're looking for urinary tract support, this product combines two ingredients with some clinical backing — but neither hits a strong dose. The 500 mg of **Cranberry** whole fruit powder falls short of the 36 mg proanthocyanidins (PACs) threshold used in most positive UTI prevention trials, and whole fruit powder is a less concentrated form than standardized extracts.
The probiotic blend delivers 1.2 billion CFU across four strains including **Lactobacillus acidophilus** and **Bifidobacterium bifidum**. That's on the low end — most clinical studies on gut and urinary health use 5–50 billion CFU. You also get 60 mg of **Vitamin C** (as ascorbic acid), which is below the supplemental range but covers your baseline RDA.
For you, the main limitation is potency across the board. Both the cranberry and probiotic doses sit well below what clinical research typically uses for measurable urinary or digestive benefits.
