A strong smell in urine is usually caused by dehydration, certain foods, vitamins, or medications. When dehydrated, urine becomes more concentrated, making its natural ammonia smell stronger. Foods like asparagus, coffee, garlic, and Brussels sprouts can impart a distinctive odor to urine. Vitamin B supplements and some antibiotics can also change urine smell. In some cases, a strong urine odor may indicate health conditions such as urinary tract infections, diabetes, or other metabolic issues, especially if accompanied by other symptoms like pain, cloudy urine, or frequent urination. Drinking plenty of water typically helps reduce the strong odor in urine.
