Beets, pink pee, and why this gets confusing
If your urine turns pink or red after eating beets, you may have beeturia—a benign color change caused by beet pigments (betalains) passing through your gut into your bloodstream and then your urine. Up to about one in ten people notice this, and the chance is higher in those with iron deficiency or certain malabsorption states. The pigments responsible are chiefly betacyanins such as betanin. [1]
Beeturia looks alarming because it mimics hematuria (blood in the urine). But food pigments, medications, and even vitamins can color urine without any bleeding. Distinguishing a harmless tint from true hematuria matters, because actual blood—especially when persistent—needs a risk-based medical work-up. [2]
Beeturia 101: what it is, what it is not
- What it is: Pink to deep red urine appearing hours after eating beets or beetroot products; color can last up to a day or two depending on how much you ate and your stomach acidity. It is harmless, though it may be more common if you have iron deficiency or malabsorption. [1]
- What it is not: It is not an infection, kidney disease, or bleeding by itself. If color persists when you are not eating beets—or if you have pain, clots, fever, or urinary symptoms—treat it as possible hematuria and get checked. [2]
Why some people get beeturia (and others do not)
Older and newer studies point to an interaction between gastric acidity, intestinal transit, and iron status. Beeturia is reported more frequently in iron deficiency anemia and in some malabsorption conditions; betanin is better absorbed and less degraded in these settings. The association is not perfectly consistent across studies, but the signal is strong enough that classic papers and reviews note it explicitly. [3]
Quick science: the pigments behind the pink
Beets contain betalain pigments. Betacyanins (like betanin) are red-purple; betaxanthins are yellow-orange (more abundant in golden beets, which rarely tint urine red). Betacyanins can survive digestion in some people and appear in urine as “beeturia.” [4]
Food color vs true blood: practical ways to tell
The goal is not to self-diagnose serious conditions, but to avoid panic when a clear food trigger exists—and to seek care promptly when it does not.
1) The timing check
- Suggests beeturia: Pink/red urine starts within hours after a beet-containing meal and fades within 24–48 hours. [5]
- Suggests hematuria: Color persists beyond two days without more beets, or appears without any beet exposure.
2) The “no-beet challenge”
Skip beets and red dyes for 48 hours. If color disappears, beeturia is likely. If it persists or returns without beets, arrange a urinalysis. [2]
3) The dipstick–microscope rule (for clinics)
A urine dipstick positive for heme should be confirmed by microscopy to verify red blood cells; heme can be positive from free hemoglobin or myoglobin even without red blood cells. Conversely, food pigments (beeturia) will yield heme-negative urine despite striking color. Some dipsticks also give false negatives for blood with high vitamin C. Your clinician knows these pitfalls. [6]
4) Look-alikes you should know
Foods and drugs that color urine red or orange include beets, blackberries, rhubarb, food dyes, phenazopyridine, rifampicin, and hydroxocobalamin (vitamin B12 injection). These can mimic hematuria at a glance. [2]
What doctors do when “it might be blood”
Modern urology uses risk-based algorithms to work up blood in urine. The American Urological Association guideline (2020, amended 2025) stratifies patients by age, amount of microscopic blood, smoking history, and other factors to decide on imaging and cystoscopy.
Translation: If your urine is pink after beets and clears in a day, you likely do not need scans. If color persists or the urinalysis confirms blood, clinicians follow a structured pathway so you do not get under- or over-tested.
A calm, step-by-step plan when your urine turns pink after beets
- Pause and recall your last meals. Beets, beet juice, beet chips, smoothies, and even red-velvet foods with beet powder can do it. If yes, you can observe for 24–48 hours. [5]
- Check for symptoms that trump the food explanation. If you have pain with urination, fever, back or flank pain, visible clots, or an inability to pass urine, seek care now—regardless of beets. Those are not typical for beeturia. [2]
- Hydrate normally and watch the color. If the color resolves without more beets, you have your answer. If it persists or returns without beets, get a urinalysis with microscopy. [6]
- Bring a smart list to your visit. Note any foods (beets, blackberries, rhubarb), supplements (vitamin C), and medicines (phenazopyridine, rifampicin, new prescriptions). These help your clinician interpret test results and avoid false alarms. [2]
- If you truly have hematuria, expect a risk-based work-up. Your clinician will apply the AUA microhematuria framework to decide on imaging and cystoscopy based on your risk profile.
Why beeturia can be more common in iron deficiency (and what to do)
Multiple studies observed more frequent beeturia in iron deficiency and malabsorption, possibly because low gastric acid or altered intestinal handling allows more betanin to survive and be absorbed. While not a diagnostic test, recurrent beeturia in someone with fatigue or pallor is a gentle nudge to screen for iron deficiency with your clinician. [3]
Clinic pearls: how professionals separate pigment from blood
- Color vs chemistry: Red urine that is heme-negative on dipstick strongly suggests pigment (beeturia, drugs, dyes). Heme-positive urine may reflect blood, hemoglobin, or myoglobin; microscopy clarifies whether red blood cells are present. [6]
- Beware vitamin C: High ascorbic acid can mask blood on some dipsticks (false negatives). Tell your clinician about supplements. [7]
- Food and drug list: Beets, blackberries, rhubarb, dyes, phenazopyridine (pain reliever for bladder irritation), rifampicin, and some medicines can color urine. [2]
- Persistent color, no beets: Treat as hematuria until proven otherwise—especially in adults over 35–40, those who smoke, or anyone with urinary symptoms. The AUA 2025 amendment supports risk-tailored evaluation.
Beeturia myths—answered quickly
- “If I get beeturia, I have kidney disease.”
No. Beeturia reflects pigment handling, not kidney damage. It is typically benign. Persistent pink urine without beets is a different story—get checked. [1]
- “Only red beets cause this.”
Mostly true. Purple/red beets contain betacyanins that can redden urine; golden beets contain betaxanthins and rarely cause red urine. [8]
- “Everyone with iron deficiency gets beeturia.”
No. The association appears more likely, not universal. Studies conflict, but several show higher rates in iron deficiency. Screening for anemia is reasonable if you have other symptoms. [3]
When pink or red urine is not from beets
Call your clinician promptly—same day, if possible—if you notice any of the following without a beet trigger:
- Visible clots or “tomato soup” urine
- Painful urination, urgency, fever (infection signs)
- Flank or back pain (possible stones)
- Recent injury or vigorous exercise with dark cola-colored urine (possible myoglobin from muscle breakdown)
- Persistent color over two days or recurring episodes with no clear food or drug link
Doctors will start with a urinalysis (dipstick plus microscopy), then apply a risk-based pathway (age, smoking, degree of microscopic blood, and history) to decide on imaging and possible cystoscopy, per AUA guidance.
For content skimmers: a concise “how-to” without panic
- Ate beets? Wait 24–48 hours; hydrate normally. If color clears, you likely had beeturia. [5]
- Still pink without beets? Get a urinalysis with microscopy; mention foods, vitamins, and medicines. [6]
- If blood is confirmed, your clinician will use the AUA 2025 risk model to plan imaging and further tests.
Frequently asked questions (SEO-friendly quick hits)
How long does beeturia last?
Usually less than 24–48 hours after eating beets, depending on dose and digestion. [5]
Can beeturia appear even if I only ate a small amount?
Yes. Sensitivity varies; some people color urine after modest amounts, especially with iron deficiency or malabsorption. [3]
Is there a quick at-home clue that it is pigment, not blood?
The timing (hours after beets, gone in a day) is the best clue. True confirmation needs urinalysis; food pigments typically produce a heme-negative dipstick. [6]
Which other foods or drugs cause red or orange urine?
Blackberries, rhubarb, food dyes, phenazopyridine, rifampicin, and vitamin B12 injections can color urine. [2]
Do I need a scan if I saw pink urine once after beets?
Generally no, if it clears and only follows beets. Persistent or recurrent color without beets warrants a urinalysis and a risk-based evaluation.
Key takeaways (for clinics and patient handouts)
- Beeturia is benign and common enough to encounter; it reflects betalain pigments in urine, not bleeding. [1]
- Do not ignore persistent color unrelated to beets—confirm with urinalysis plus microscopy; dipsticks have false positives and false negatives. [6]
- Follow AUA 2025 risk-stratified pathways for confirmed hematuria; they reduce unnecessary tests while catching important disease.
