7 Side Effects Of Drinking Beetroot Juice In Excess

Beetroot juice is mostly consumed as part of a healthy diet and has many benefits. But are you aware of the side effects of beetroot juice? The major side-effects include kidney problems and liver damage. For instance, beetroot (beta vulgaris or beet plant) is high in oxalates that bind with calcium and may trigger the formation of kidney stones in vulnerable individuals (1).

Accumulation of metal ions in the liver is also associated with excess consumption of beetroot (2).

Fun Fact

Beetroots are derived from sea beets or wild beets grown on the Mediterranean coast. European immigrants introduced the plant to Americans.

What Are The Side Effects Of Beetroot Juice?

Is beet juice good for you? The answer would be probably yes as it is mostly consumed as part of a healthy diet and has many health benefits. Packed with vitamin C, iron, manganese, folate, folic acid, oxalic acid, fatty acids, and fiber content, concentrated beetroot juice has several health benefits. However, it is important to know the side effects of drinking this juice too.

1. Might Cause Beeturia

Beeturia is characterized by the discoloration of urine following the intake of beets or foods colored with beta vulgaris. Urine may range from pink to deep red, and this condition could be prevalent in about 14% of the population and have increased frequency in those with iron deficiency (3).

A study conducted on eight older adults showed that the intake of beetroot juice supplements could lead to beeturia in all but one individual (4).

For the majority, beeturia is not a disease but a harmless phenomenon that resolves on its own once the individual reduces the intake of beet/beet juice (3).

Jordana Tobelem, Registered Dietitian/Nutritionist, says, “Beetroot juice is absorbed by the body quickly. Once you drink beetroot juice, you will feel the effects within 2-3 hours, and it may last up to 24 hours. For the best results, it is recommended to drink about 1-2 cups, which is around 310-560 mg.”

2. May Increase Kidney Stone Risk

According to Clinical Nutrition Research, beets are rich in oxalic acid and may contribute to stone formation (1). If you already have stones, your doctor might recommend you to stop or reduce beetroot extract/beetroot juice consumption.

Symptoms of kidney stones include fever, vomiting, nausea, diarrhea, sharp pains in the abdomen and groin, and discoloration of urine. There are four types of kidney stones, with calcium being the most common of all. The mineral can combine with other substances, especially oxalic acid, and form a stone. There is limited research available on beetroot causing decreased calcium absorption. While the beetroot is a good source of other nutrients like vitamins, iron, dietary fiber, and minerals, it is low in calcium.

Beetroot is high in oxalate and can directly contribute to kidney stones. It increases urinary oxalate excretion, which can lead to the development of calcium oxalate stones (1).

3. May Cause Anaphylaxis

Though rare, beta vulgaris may cause anaphylaxis, which is an acute allergic reaction to an allergen to which the body has become hypersensitive.

In a study, a young girl complained of urticaria (red rashes on the skin that itch intensely, sometimes leading to dangerous swelling) and asthma after ingesting boiled beetroot (5). The girl also experienced hivesⁱ  XRaised and itchy patches of skin caused by an allergic reaction to food, medicine, or other irritants. , throat tightness, and bronchospasmⁱ  XTightening of the muscles lining the airway in the lungs, which can result in wheezing, coughing, and chest pain. . She has advised a diet free of beetroot, and she had no symptoms again (5).

4. May Cause Colored Stools

Beetroot (and foods with red coloring, like grape juice and pomegranate juice) may cause stools to appear reddish (6).

There is some evidence that beetroot may also cause black and tarry stools due to the presence of altered blood (7).

Dark and tarry stools could also be a symptom of beeturia. You may want to visit your doctor and discuss your recent dietary choices and history of similar events (3).

Trivia

During ancient Greek and Roman times, beets were either white or black and were called Roman beets.

5. May Cause A Stomach Upset

Beetroot contains nitrates*. According to a publication by the U.S. Department of Health and Human Services, the nitrates in beetroot juice may cause abdominal cramps. Exposure to high levels of nitrate may lead to stomach cramps and vomiting (8). The increased nitrate level may result in adverse effects like decreased blood flow and increased heart rate.

The juice may also cause stomach problems in some people (9).

According to Jordana Tobelem, Registered Dietitian/Nutritionist, “The side effects of beetroot juice are rare, but some individuals have reported gastrointestinal side effects. The nitrates in the beetroot juice may cause abdominal cramps in those who already have sensitive stomachs.”

*Beetroot and certain other foods contain nitrates, which are converted to nitrites upon ingestion.

6. May Cause Problems During Pregnancy

The dietary nitrates in beets may cause a problem here. Pregnant women are more sensitive to the effects of nitrate. This can be attributed to the natural increase of methemoglobinⁱ  XA form of hemoglobin that cannot bind to oxygen, which hinders oxygen transportation to the tissues. levels in the blood during the later stage of pregnancy.

Excess dietary nitrate can lead to methemoglobinemia (elevated levels of methemoglobin in the blood), causing symptoms like lack of energy, headache, dizziness, blue-gray coloration of skin around the eyes, mouth, lips, hands, and feet (10).

Though most epidemiological studies of pregnant women having elevated nitrate levels in their groundwater did not show any negative effects on their offspring, one study found an association between dietary nitrates and an increase in neural tube defectsⁱ  XSevere deformities of the brain or spine that a fetus develops within the first few months of pregnancy. (10). Therefore, consuming the nitrate-rich beetroot juice is not a good idea for pregnant women.

7. Might Harm The Liver

Studies suppose that extreme intake of table beetroot may cause several disturbances not only in healthy patients but also in those dealing with metal-accumulating diseases (2).

Excess intake of the veggie can cause the accumulation of metal ions in the liver (2). Though it is a healthy juice, its excessive consumption may affect liver health.

In addition, there are no documented beet juice and drug interactions. “Beetroot juice does not have any known drug interactions. However, since beets can have a lowering effect on blood pressure, those who take blood pressure medications should avoid high amounts of beets. Combining blood pressure medications with beets may lead to low blood pressure,” says Jordana Tobelem, Registered Dietitian/Nutritionist.

How Much Of Beetroot Juice Is Too Much?

There is limited research and no official recommendation regarding the safe dosage of beetroot juice. Hence, it is best to consult with your doctor to know more about the daily intake, whether drinking beetroot juice is safe for you, and how many glasses of juice you can consume per day. Your doctor may be able to give you a personalized recommendation based on your health condition.

Fun Fact

During the mid-19th century, beetroot juice was used as an ingredient to add color to wines.

A Note On SuperBeets

SuperBeets is a popular health supplement that allegedly lowers blood pressure and improves circulation. This dietary supplement is made of beetroots that are dehydrated into crystals.

There only is one study about SuperBeets, and concrete evidence on its efficacy to lower blood pressure is lacking. This beetroot supplement may lower blood pressure levels, but more research is warranted (11).

Most testimonials from people state that the supplement can lower systolic blood pressure and diastolic blood pressure and improve red blood cell production. However, certain others reported no beneficial effect. Exact information on SuperBeets is lacking.

If you are vulnerable to the side effects of drinking beetroot juice, the supplement could do more harm than good. Hence, it is imperative to discuss this with your doctor.
