Red Urine? Why Your Body Is Reacting to Beets & What to Do Next

Seeing red urine can be alarming. Your first thought might be blood. But if you recently ate beets, there's a good chance the color change is harmless.

Still, red urine should never be ignored without thought. Sometimes it's diet-related. Other times, it signals a medical issue that needs attention.

Here's what you need to know — clearly, calmly, and based on credible medical evidence.

Can Beets Really Turn Your Urine Red?

Yes. This phenomenon is called beeturia.

Beets contain a natural red pigment called betalain (specifically betanin). In some people, this pigment isn't fully broken down during digestion. Instead, it's absorbed into the bloodstream and later filtered by the kidneys — turning urine pink, red, or even purple.

Important facts about beeturia:

• It can happen within 4–8 hours of eating beets.
• The color may last up to 24–48 hours.
• It can also cause reddish stool.
• It is usually harmless.

Not everyone who eats beets develops red urine. Studies suggest beeturia occurs in about 10–14% of the population, though it may be more common in people with:

• Low stomach acid
• Iron deficiency
• Certain digestive conditions

That said, beeturia alone does not automatically mean you have iron deficiency or a health problem.

Why Do Beets Affect Some People but Not Others?

The body's ability to break down beet pigments depends on several factors:

• Stomach acid levels – Higher acidity breaks down betalain more effectively.
• Iron levels – Some research shows beeturia may be more noticeable in iron deficiency.
• Gut bacteria composition
• How many beets you ate – Larger portions increase the chance.

For example, drinking beet juice, eating roasted beets, or having a beet smoothie can increase the likelihood of red urine compared to eating a small portion in a salad.

How to Tell If It's Just Beets — or Something More Serious

Red urine from beets usually has these features:

✅ Occurs shortly after eating beets
✅ No pain or discomfort
✅ Color fades within 1–2 days
✅ You otherwise feel well

However, blood in urine (called hematuria) can look very similar — and may signal something more serious.

Red urine is more concerning if you notice:

• Pain or burning when urinating
• Lower back or side pain
• Fever
• Frequent urination
• Blood clots in urine
• Red urine without eating beets
• Persistent discoloration beyond 48 hours

If you're experiencing any of these symptoms and need help determining whether your red urine is a medical concern, you can use a free blood in urine symptom checker to get personalized guidance within minutes.

This can help you decide whether urgent care is needed.

What Else Causes Red Urine?

1. Urinary Tract Infection (UTI)

• Burning with urination

• Cloudy urine

2. Kidney Stones

• Nausea
• Blood in urine

3. Bladder or Kidney Infection

• Fever
• Chills

4. Kidney Disease

6. Cancer (Bladder or Kidney)

When Should You See a Doctor?

Do not panic — but do not ignore red urine if:

• You did not eat beets
• The color lasts more than 48 hours
• You see clots
• You have pain, fever, or urinary symptoms
• You are over 40 years old and notice unexplained blood
• You have a history of smoking
• You have a personal or family history of kidney disease

Even painless blood in urine can signal a serious condition. It's better to check and be reassured than to miss something important.

How Doctors Evaluate Red Urine

If you see a healthcare professional, they may:

• Ask about recent foods (especially beets)
• Perform a urinalysis (simple urine test)
• Check for infection
• Order imaging (ultrasound or CT scan) if needed
• Refer you to a urologist in certain cases

If it's beeturia, no treatment is needed.

If it's blood, identifying the cause early makes treatment more effective.

Are Beets Safe to Eat?

Yes — for most people, beets are very healthy.

They are rich in:

• Fiber
• Folate
• Potassium
• Vitamin C
• Antioxidants
• Natural nitrates (which may support heart health)

Beets have been studied for potential benefits in:

• Lowering blood pressure
• Supporting exercise performance
• Improving blood flow
• Supporting gut health

If beets turn your urine red but you feel well, you do not need to avoid them unless advised by your doctor.

How to Test If It's Beeturia

If you suspect beets are the cause:

1. Stop eating beets for several days.
2. Wait for urine color to return to normal.
3. Reintroduce beets in a controlled amount.
4. Observe whether red urine returns.

If it consistently happens only after eating beets and resolves quickly, it's likely harmless beeturia.

If red urine occurs without beets, get checked.

A Balanced, Practical Approach

It's easy to jump to worst-case scenarios when you see red urine. But context matters.

Ask yourself:

• Did I recently eat beets or drink beet juice?
• Do I feel otherwise well?
• Is there pain or other symptoms?
• Has this happened before?

If everything points to beets and it resolves quickly, it's usually nothing to worry about.

If anything feels off — trust that instinct and seek medical advice.

The Bottom Line

Red urine after eating beets is common and usually harmless. It's caused by natural pigments that pass through your body unchanged.

However:

• Not all red urine is from beets.
• Blood in urine should never be ignored.
• Painless blood can still signal serious conditions.

If you're unsure what's causing your red urine, a quick and free blood in urine symptom checker can help you understand whether you need to see a doctor right away.

And most importantly:

If red urine is persistent, painful, unexplained, or accompanied by other symptoms, speak to a doctor promptly. Some causes can be life-threatening if ignored, but highly treatable when caught early.

Stay informed. Stay calm. And don't ignore what your body is trying to tell you.
