What does a urine with no bubbles mean?
Well, the existence of bubbles in urine is a sign of excess protein, so the lack of bubbles must mean that you don't have an excess of protein.
At any rate, having "no bubbles" is not a bad thing.
To shorten what Colleen said,no bubbles means your probably eating a drinking healthier,I noticed the exact same thing when I started drinking a lot more water,certain things changed about it.
