Our verdict

KAL D Mannose Powder 1600 mg works out to $0.61 per serving of d-mannose, at 1600mg per serving in powder form. That puts it above the median of the 16 d-mannose products we can price per dose, where the typical serving costs $0.18, a Value Index of 0.3 where the median product is 1.0. One container lasts 45 days at the label dose of 1 serving a day, about $18.19 a month. We could not verify a third-party certification for KAL in a public registry.
