Beetroot juice has real nutritional value that can support your body during menstruation, but the benefits are more modest than many wellness sites suggest. It provides iron, folate, and vitamin C, all nutrients your body needs more of when you’re losing blood. However, there’s very little direct research on beetroot juice and periods specifically, and one study in women actually found a surprising downside for exercise performance. Here’s what the evidence actually shows.
What Beetroot Juice Offers Nutritionally
One cup (about 248 grams) of beetroot juice contains 1.4 mg of iron, which covers roughly 8% of the recommended daily value. That’s a meaningful contribution but not a game-changer on its own. During your period, you lose iron through blood, so any dietary iron helps replenish your stores. The iron in beetroot is non-heme iron, the plant-based form, which your body absorbs less efficiently than iron from meat. The good news is that beetroot juice also contains vitamin C, which is one of the strongest enhancers of non-heme iron absorption. Vitamin C forms a chemical partnership with plant iron that keeps it in a form your gut can actually take up, even counteracting substances that normally block absorption like tea or calcium.
Beetroot also delivers about 109 micrograms of folate per 100 grams. Folate is essential for producing new red blood cells, the very cells you’re losing during menstruation. Without enough folate, your body produces oversized, immature red blood cells that don’t function properly, a condition called megaloblastic anemia. While a glass of beetroot juice won’t single-handedly prevent this, it adds a solid folate boost alongside other foods in your diet.
Can It Help With Cramps?
This is where the claims get ahead of the science. Beetroot juice is rich in dietary nitrates, which your body converts into nitric oxide. Nitric oxide relaxes smooth muscle, including the muscles in blood vessel walls, and research has confirmed that this relaxation mechanism exists in uterine tissue. The logic goes: if nitric oxide relaxes the uterus, beetroot juice might ease menstrual cramps.
The problem is that no clinical studies have actually tested this. A 2023 review looking for research on beetroot juice and menstrual pain (dysmenorrhea) found essentially nothing. The uterine relaxation data comes from animal studies on pregnant rats, and those same studies found the effect disappeared during labor, when the uterus was actively contracting. Period cramps involve a different hormonal environment than pregnancy, so it’s genuinely unclear whether the nitric oxide from a glass of beet juice would translate into cramp relief. It might help, but right now that’s speculation, not evidence.
The Surprising Exercise Finding
Many people drink beetroot juice for an energy boost, hoping the nitrate content will improve blood flow and reduce fatigue. During your period, when fatigue often peaks, this sounds appealing. But a study published in the Journal of Applied Physiology tested beetroot juice supplementation in healthy young women across different phases of the menstrual cycle and found the opposite of what you’d expect.
Women who took beetroot juice actually performed worse on endurance tests, lasting about 48 seconds less (roughly 10% shorter) compared to a placebo. This effect showed up regardless of which phase of the menstrual cycle they were in. Exercise efficiency, meaning how much energy their bodies used for a given effort, wasn’t improved either. The researchers concluded that healthy women “should proceed with caution when considering supplementation with BRJ.” This doesn’t mean beetroot juice will make you feel more tired in daily life, but the idea that it reliably fights menstrual fatigue doesn’t hold up in the data we have so far.
Replacing Lost Nutrients After Blood Loss
Where beetroot juice makes the most practical sense during your period is as part of a broader strategy to replace what you lose. Menstrual blood contains iron and red blood cells, and your body needs raw materials to rebuild both. Beetroot juice delivers three of those raw materials in one drink: iron for hemoglobin production, folate for new red blood cell formation, and vitamin C to help absorb the iron.
To get the most from that iron, drink your beetroot juice on its own or with other vitamin C-rich foods rather than alongside tea, coffee, or dairy. These contain compounds that bind to non-heme iron and prevent your body from absorbing it. Timing matters more than quantity here.
Don’t Panic About Red Urine
If you drink beetroot juice during your period and notice your urine turning pink or red, you might worry it’s blood. This is almost certainly beeturia, a harmless condition where pigments from beets pass through your system and color your urine. It affects 10% to 14% of the general population and is more common in people who are iron deficient, which means menstruating women are more likely to experience it. Up to 45% of people with certain types of anemia notice beeturia. It’s not dangerous, but knowing about it in advance saves unnecessary alarm, especially when you’re already monitoring for menstrual symptoms.
Who Should Be Careful
Beetroot juice is notably high in oxalates, containing 60 to 70 mg per 100 ml. That’s dramatically higher than nearly all other fruit and vegetable juices, which fall below 10 mg per 100 ml. Oxalates bind to calcium in your body and can contribute to kidney stone formation. If you have a history of calcium oxalate kidney stones, even 500 ml of beetroot juice can meaningfully increase the oxalate load your kidneys have to process. High oxalate intake also reduces how well your body absorbs calcium and magnesium, which could work against you during your period when mineral balance already matters.
For most people without kidney stone history, a single glass of beetroot juice during your period is perfectly safe. Keeping your intake to around one cup (roughly 250 ml) per day is a reasonable amount that delivers nutritional benefits without overloading on oxalates. Drinking plenty of water alongside it helps your kidneys process the oxalate more easily.
The Bottom Line on Beetroot Juice and Periods
Beetroot juice is a genuinely nutritious drink that provides iron, folate, and vitamin C in a combination that supports blood rebuilding after menstrual loss. Those benefits are real but incremental. It won’t dramatically reduce cramps, and it won’t reliably boost your energy. Think of it as one useful piece of your diet during menstruation rather than a remedy. Pair it with other iron-rich foods, stay hydrated, and don’t expect it to do what a balanced overall diet does.
