Provita UTI Complex - Contains Cranberry juice extract and D-Mannose. Both plants have been traditionally used for naturally preventing the re-occurrence of urinary tract infections, in particular caused by E. coli bacteria. The presence of a high dose of D-Mannose in this formula is essential. Both Cranberry and D-mannose prevent the bacterial fimbriae (outside hair) from attaching to the urinary tract wall and be easily flushed out through normal urine flow. Together they form the most powerful synergistic combination for naturally treating urinary tract infections. Diuresis (increased production of urine) is stimulated by Uva-ursi and Betula pendula and Juniperus communis. By stimulating diuresis, bacteria are flushed away. Juniperus communis also doubles as a powerful natural antiseptic.
