Daily beetroot juice showed early but promising signs of safely supporting pregnant women living with chronic kidney disease, according to a new UK research. Consequently, this simple, low-cost drink could soon offer a much-needed option for mothers who currently have very few safe treatments.
For a pregnant woman with chronic kidney disease, or CKD, protecting her own kidneys becomes significantly harder just as her body is supporting a developing baby. Many standard kidney treatments are considered unsafe during pregnancy and often require medication to be paused for at least nine months.
Why Is Pregnancy So Risky for Women With Kidney Disease?
Pregnancy naturally increases the workload placed on the kidneys as they filter more blood for both mother and baby. Among women with moderate to severe CKD, approximately half experience worsening kidney function while pregnant, which raises risks for both mother and newborn.
Yet, despite advances in medicine, outcomes for this high-risk group have improved little over the past three decades. Therefore, clinicians have been left with few safe and effective ways to reduce the risk of kidney decline during pregnancy. Researchers at King’s College London are now investigating whether a daily serving of nitrate-rich beetroot juice could provide a simple and accessible form of support.
How Could Beetroot Juice Help Protect Kidneys?
Beetroot contains exceptionally high levels of dietary nitrate, which the human body naturally converts into nitric oxide. This vital molecule relaxes blood vessels and improves circulation throughout the body, raising the possibility that it could ease some of the additional pressure placed on kidneys during pregnancy. The study, published in the peer-reviewed journal Kidney International Reports, examined this dietary nitrate approach as a possible option for supporting kidney health during high-risk pregnancies.
Researchers enrolled 108 pregnant women with stage 2-5 chronic kidney disease at eight hospitals across the United Kingdom. Before 25 weeks of pregnancy, participants were randomly assigned to receive either standard care alone or standard care with a daily nitrate-containing beetroot juice supplement.
What Did The Study Find? Early Results Show Fewer Complications
The trial was primarily intended to determine whether a larger clinical study could be conducted successfully and safely. Although it was not designed to provide definitive proof of effectiveness, the early results pointed to possible benefits for both mothers and newborns.
Kate Bramham, Consultant Nephrologist at King’s College Hospital and senior author, said: “For women living with chronic kidney disease, pregnancy has always meant navigating a difficult trade-off between preserving their own health and keeping their baby safe, often with few tools to do both.” She added, “These results are an encouraging first step toward a low-cost, low-risk intervention that could genuinely make a difference for this group of women, who have been underserved by research for far too long.”
Participants who received beetroot juice experienced about 70% fewer serious adverse events overall than those given standard care alone. Among the serious events recorded in the study, approximately half involved newborn babies, highlighting the need for maternal-fetal protection.
The researchers also observed encouraging patterns among women with more advanced kidney disease specifically. These included better kidney function after pregnancy, fewer newborn admissions to neonatal care, and less need for blood pressure medication during pregnancy.
Is Beetroot Juice Safe During Pregnancy With CKD?
Safety is the most critical question for any intervention during pregnancy, especially for women with kidney disease. Importantly, the beetroot juice supplement was not associated with any identified safety problems during the entire trial period. In particular, researchers found no increase in hyperkalemia, a potentially dangerous buildup of potassium in the blood that can affect heart rhythm. Some online guidance has previously warned pregnant women with CKD against consuming beetroot juice because of concerns that it might raise potassium levels.
However, this controlled study did not find a higher rate of hyperkalemia among participants who received the daily supplement.
Dr. Priscilla Smith, nephrologist and first author, said: “Pregnancy can put additional stress on the kidneys, and for women with chronic kidney disease there are currently limited options to protect kidney function during this time. Our findings suggest beetroot juice could offer a simple and accessible approach that is safe and worth exploring further.”
Analysis: Why This Low-Cost Drink Could Be A Game-Changer
This research matters because it addresses a major gap in maternal medicine for an underserved population. Currently, women with CKD face a difficult trade-off with little middle ground, and expensive new drugs are often not an option during pregnancy. Dr. Andrew Webb, co-author, said: “By increasing nitric oxide production, dietary nitrate from beetroot juice may help improve blood vessel function and support kidney health. These early findings provide an important foundation for future research.”
If larger trials confirm these benefits, beetroot juice could provide an inexpensive, widely available, and culturally acceptable option during pregnancy when safe treatments are extremely limited.
Q&A
Q: Can pregnant women with kidney disease drink beetroot juice?
A: Early results from King’s College London suggest daily nitrate-containing beetroot juice was safe and showed fewer complications, but women should always consult their nephrologist before trying it.
Q: How much beetroot juice was used in the study?
A: The study used a daily nitrate-containing beetroot juice supplement started before 25 weeks of pregnancy, but the exact commercial dose should only be replicated under medical supervision in future trials.
Frequently Asked Questions
1. Is beetroot juice safe during pregnancy with chronic kidney disease?
The preliminary UK trial of 108 women found no safety concerns and no increased potassium levels, but researchers emphasize larger trials are needed before it becomes standard care.
2. How does beetroot juice support kidney health in pregnancy?
Beetroot provides dietary nitrate that converts to nitric oxide, which relaxes blood vessels, improves blood flow, and may reduce the extra pressure placed on kidneys during pregnancy.
3. What are the risks of CKD during pregnancy?
About half of women with moderate to severe CKD experience worsening kidney function during pregnancy, increasing risks of high blood pressure, preterm birth, and need for neonatal care.
4. Will beetroot juice become a standard treatment for CKD pregnancy?
Not yet. Researchers say the findings remain preliminary and larger clinical trials must confirm whether it significantly limits kidney function decline and improves long-term outcomes.
Final Word: While not definitive, this study offers genuine hope for a low-risk, low-cost way to support mothers and babies when treatment options are severely limited.
