    Asparagus contains a chemical completely unique to its namesake called asparagusic acid. When our bodies digest this vegetable, they break down its acid into other, smaller, sulfur-containing enzymes. Because these enzymes are volatile, they can become gaseous at room temperature. Therefore, when you excrete them, they quickly interact with the air around you causing a rather unpleasant, sulfuric odor. [1]

    The more hydrated you are, the more the smell of your pee is diluted. Before or after eating asparagus, drink lots of water to help neutralize its scent. [2]

    Doctors recommend drinking cranberry juice to neutralize the scent of particularly smelly urine, because it makes your pee slightly more acidic. Try a little cranberry juice before you have some asparagus. Just make sure its sugar content is low. Otherwise, you might make the situation worse! [3]

    Vitamin C has been proven as an effective pee deodorizer. Taking a recommended dose of vitamin C tablets (whatever is advised on the bottle) can help counterbalance asparagus’ smell in your urine. Just make sure to talk to your doctor beforehand. [4]

    Because the foul-smelling compounds in asparagus pee are gaseous, neutralize them the way you would any other gas. Open up a window and allow the aroma to dissipate outside.

    Air fresheners are literally designed to promote good odors and mask bad ones. Keep an air freshener handy in your bathroom and it should make the scent of asparagus pee hardly noticeable.

    The bad news: the smell of asparagus pee will never be totally neutralized. The good news: the smell is totally normal and healthy. The best way to deal with the scent is to simply let your body digest this nutritious vegetable the way it needs to. Just let things be; in a few hours, the aroma should be gone anyways. [5]

    Scientists have been observing a change in urine aroma after eating asparagus for centuries. Approximately 20% to 50% of the population experiences this phenomenon. It’s simply a sign of your body digesting food healthily. [6]

    Believe it or not, between 58% and 61% of people can’t even detect a difference in the smell of urine after eating asparagus. With a genetic variation in their olfactory (smell) receptors, the majority of humans have what’s called “asparagus anosmia.” So, next time you feel embarrassed going to a public restroom after eating asparagus, relax because there’s a decent chance others won’t even notice. [7]
    • Some people have a metabolic mutation that makes them unable to produce the asparagus smell when peeing too. [8]

    Smelly pee is nothing to be concerned about after eating asparagus. However, if you have a runny nose or trouble breathing, you may be having an allergic reaction and should avoid eating the vegetable altogether. [9]

    Usually, the smell of asparagus pee will disappear after about 14 hours. However, if the smell lasts longer than 2 days, or you notice a major change in color, frequency, or sensation, contact a medical professional as there may be something more serious going on. [10]
