Smelly urine

Smelly pee (urine) on its own is not usually something to worry about. There are often things you can do to help your pee get back to normal.

Common causes of smelly pee

Pee is usually clear or pale yellow with a mild smell.

Common things that can make your pee smell stronger include:

  • certain types of food and drink, like asparagus or coffee
  • not drinking enough fluids
  • some medicines
  • vitamin B6 supplements

There are some things you can do to help keep your pee clear and smelling mild.

Do

Don't

  • do not eat a lot of garlic or asparagus - they contain strong-smelling chemicals that can pass into your pee

  • do not take more than 10mg of vitamin B6 a day
