Much better condition

2 people found this helpful

I enjoy the pleasant taste and appreciate its purity as it is just D-Mannose without any other ingredients. After taking one teaspoon in water every morning and evening, my irritable bladder problem has improved significantly.

Helps significantly

I am using this for my chronic UTI and irritable bladder syndrome. I believe it is helping me a lot, which is encouraging.

Minimal effect

I purchased this for my irritable bladder symptoms. The powder is very fine and quite soft, dissolving easily in water with a subtle taste, perhaps a little sweet. I feel it has a slight effect on my irritable bladder, but I don't expect too much from it.
