My partner used to suffer from continual and recurrent Thrush infections due to her health conditions (CF and Diabetes) and we suspected that the well known brand of lube was exacerbating the problem as it was so sticky and full of sugar. We googled the problem in an attempt to find a solution and discovered Yes. We were a bit sceptical at first as it is a bit more expensive than others but upon using the product and finding it to be absolutely brilliant and fixing our issue, we wouldn't now consider using anything else as it is totally perfect and the water lube mimics the real thing. A lot of the reviews on here mention a health problem or other but I would recommend this to anyone health condition or not, it is simply the best lube on the market.
