Urinary Tract Infections (UTI)
Flush bacteria from the urinary tract, block E. coli from adhering to the bladder wall, and calm the burning, urgency, and frequency that come with cystitis and recurrent infections.
D-mannose
OtherStrong evidence2 g powder in water 2–3× daily at first symptoms (then 1–2 g/day for prevention). Binds E. coli fimbriae so bacteria are flushed out in urine instead of sticking to the bladder wall — the best-studied non-antibiotic option for recurrent UTIs.
Cranberry extract (PACs)
FoodStrong evidenceStandardized to 36 mg proanthocyanidins/day (capsule or unsweetened juice). Prevents bacterial adhesion; most useful for recurrence prevention rather than treating an active infection.
Uva ursi (bearberry)
HerbModerate evidenceStandardized leaf extract (≈400–800 mg/day arbutin) for ≤1 week at the first sign of a UTI; works best in alkaline urine. Not for pregnancy, breastfeeding, or long-term use.
Hibiscus extract
HerbModerate evidence200 mg/day standardized hibiscus (Hibiscus sabdariffa) has been shown in trials to reduce UTI recurrence by acidifying urine and exerting antimicrobial action.
Buchu
HerbTraditional useTraditional South African urinary antiseptic — tea or tincture used for cystitis, burning urination, and mild bladder inflammation.
Corn silk
HerbTraditional useGentle demulcent diuretic; tea (1–2 tsp dried silk per cup, 3× daily) soothes bladder irritation and supports flow.
Marshmallow root
HerbTraditional useCold infusion (1 tbsp root steeped in cold water overnight) coats and soothes an inflamed bladder and urethra during acute UTIs.
Goldenseal
HerbTraditional useBerberine-rich root (250–500 mg 2–3× daily, short-term) with antimicrobial action against E. coli; avoid in pregnancy and combine with a practitioner's guidance.
Vitamin C
VitaminModerate evidence500–1000 mg 2–3× daily during an acute UTI acidifies urine and supports immune response; combine with plenty of water.
Probiotics (Lactobacillus)
OtherModerate evidenceL. rhamnosus GR-1 and L. reuteri RC-14 (oral or vaginal) help restore the urogenital microbiome and reduce recurrent UTIs, especially in women.
Garlic
FoodModerate evidenceRaw clove or aged garlic extract (600–1200 mg/day) has broad antimicrobial activity, including against drug-resistant uropathogens.
Plenty of water
OtherStrong evidenceAim for ~2.5–3 L/day during an active UTI to mechanically flush bacteria; pair with frequent, complete bladder emptying.
