Symptoms, conditions and causes

Why do I have an abnormal color urine?

Typically, your urine should be a straw yellow color. If it is different, various causes can underlie those unusual colors.

Dark urine

Dark urine could mean that the urine is too concentrated. This could indicate that you need to drink more water.

Clear urine

This probably means it’s too diluted, which could mean you’re consuming too much water. You could actually be diluting your electrolytes, weakening the heart.

Bright yellow urine

This could happen after consuming too many synthetic B vitamins. Reduce the amounts or substitute with natural B vitamins in this case.

Red/Rust urine

Dark red could indicate blood in the urine, kidney stones, UTI or prostate problems. Also intense running can cause it by moving your kidney up and down for a long time, causing it to have hard time to properly filter the blood.

Dark orange or brown urine

This could point to liver/gallbladder issues. Potentially it could come from flagyl (an antibiotic), muscle injury, excessive exercise, kidney damage, excessive fava beans or eating rhubarb. Consuming more vegetables may help.

Pink urine

This could happen after eating beets or come from a small amount of blood in the urine. Potassium citrate may help.

Green urine

This could come from eating asparagus.

Foamy urine

This could mean there is too much protein in the urine. It can happen from consuming too much protein, or you may need to support your kidneys.

Blue urine

This could mean there is too much calcium in your body. It can come from consuming a lot of vitamin D. Too much intake of B vitamins can also cause it. Consuming vitamin K2 and reducing amounts of calcium should help.

Black urine

If your urine is black, the cause could be an antibiotic called flagyl or it could be the herb cascara laxative or the sweetener sorbitol.
