Who Shouldn't Eat Mangosteen? Key Risks and Precautions

3 min read

While celebrated as a superfood, research indicates that the xanthones in mangosteen can slow blood clotting. This critical effect is one reason why certain individuals, particularly those with bleeding disorders or those facing surgery, should avoid eating mangosteen.

Quick Summary

An overview of health precautions and risks associated with mangosteen consumption. Explore who should avoid this tropical fruit, including individuals with bleeding disorders, those taking blood-thinning medications, and pregnant or breastfeeding women. The article also covers potential side effects from excessive intake.

Key Points

  • Blood Clotting Concerns: Mangosteen contains xanthones that can slow blood clotting, posing a risk for individuals with bleeding disorders or those on anticoagulant medications like warfarin.

  • Surgery Prep Caution: Due to its blood-thinning effects, mangosteen consumption should be stopped at least two weeks before any scheduled surgical procedure to prevent increased bleeding.

  • Pregnancy and Breastfeeding Advisory: Insufficient safety data exists for pregnant and breastfeeding women; therefore, avoidance is recommended to mitigate potential risks.

  • Digestive Issues from Excess: Overconsuming mangosteen, particularly in concentrated forms, can lead to gastrointestinal problems such as bloating, constipation, or diarrhea.

  • Drug Interaction Potential: Concentrated mangosteen products may interfere with certain medications, including blood thinners and potentially some cancer treatments.

  • Diabetes Monitoring: Individuals with diabetes or insulin resistance should monitor blood sugar closely, as mangosteen supplements might affect glucose levels.

Mangosteen and Its Impact on Blood Clotting

One of the most significant reasons why some individuals should not eat mangosteen relates to its effect on blood clotting. The fruit, particularly its pericarp and concentrated supplements, contains compounds called xanthones. These powerful antioxidants have been shown in some studies to slow blood clotting. This effect is of great concern to several groups of people.

People with Bleeding Disorders

For individuals with existing bleeding disorders, such as hemophilia, or other conditions that impair the body's natural clotting mechanisms, mangosteen poses a serious risk. The xanthones can further inhibit platelet aggregation, potentially increasing the risk of prolonged bleeding and bruising. Even moderate consumption could worsen a person's condition and lead to complications.

Patients on Blood-Thinning Medication

Many people take anticoagulant or antiplatelet drugs (often called blood thinners) to prevent blood clots. This includes common medications like warfarin (Coumadin), clopidogrel (Plavix), and aspirin. Because mangosteen also slows blood clotting, combining it with these medications can lead to a dangerous interaction, significantly increasing the risk of bleeding. A healthcare provider should always be consulted before introducing mangosteen into the diet for anyone on these drugs.

Mangosteen and Surgical Procedures

The blood-thinning properties of mangosteen also make it a major concern for patients preparing for surgery. To minimize the risk of excessive bleeding during and after a procedure, doctors often advise patients to stop taking medications and supplements that affect blood clotting.

Precautions for Surgery Patients

  • Risk of hemorrhage: Consuming mangosteen up to two weeks before a scheduled surgery could increase the risk of bleeding.
  • Delaying healing: Post-surgery, improper clotting could also delay the healing process.
  • Informed decisions: Patients should inform their surgeon and anesthesiologist about all supplements they are taking, including mangosteen, well in advance of the operation.

Other Considerations and Special Populations

Beyond blood-related issues, other groups should approach mangosteen with caution, especially when it comes to concentrated products like juices and supplements.

Pregnancy and Breastfeeding

There is currently insufficient reliable information to confirm the safety of mangosteen consumption during pregnancy or while breastfeeding. The best course of action is to avoid it entirely during these life stages to remain on the safe side and prevent any potential harm to the mother or infant.

Diabetes and Blood Sugar

While some research suggests mangosteen may have insulin-sensitizing effects, it still contains natural sugar. Individuals with diabetes or insulin resistance should monitor their blood sugar levels closely, especially when consuming higher concentrations found in juices or supplements. A healthcare provider's guidance is recommended.

Comparison of Mangosteen Risks vs. Benefits

Feature Risks for Vulnerable Groups Potential Benefits for Healthy Individuals
Blood Health Increased bleeding risk, slowed clotting. Antioxidant support.
Surgical Outcomes Increased risk of hemorrhage, delayed healing. Not applicable.
Pregnancy Insufficient safety data, potential complications. Potential immune support (though high risk for supplement).
Diabetes Potential blood sugar fluctuations, especially with supplements. Potential for improved insulin sensitivity (research ongoing).
Digestive Issues Can cause constipation or diarrhea with excessive intake. Dietary fiber aids digestion.

Potential Side Effects from Excessive Consumption

Even for those without pre-existing conditions, consuming too much mangosteen can lead to adverse effects. A balanced approach is crucial.

Potential Side Effects:

  • Digestive discomfort: The fruit's high fiber content can cause constipation, bloating, or diarrhea if eaten in large quantities.
  • Lactic acidosis: One serious case study linked excessive mangosteen juice consumption to lactic acidosis, a severe buildup of acid in the bloodstream.
  • Nausea and fatigue: Overconsumption has been anecdotally associated with feelings of nausea and tiredness.

Conclusion: Consult a Professional

While the fresh mangosteen fruit is generally considered safe for most people in moderation, it's not risk-free for everyone. The powerful compounds it contains, particularly the xanthones, can have a significant effect on blood clotting, posing a real danger to individuals with bleeding disorders, those on blood-thinning medication, and patients facing surgery. Furthermore, those who are pregnant or breastfeeding, as well as people with diabetes, should exercise extreme caution or avoid it entirely due to a lack of sufficient safety data or potential drug interactions. As with any significant dietary change or new supplement, the best course of action is always to consult with a qualified healthcare professional. They can provide personalized advice based on your medical history and current health status, ensuring you make a safe and informed decision about whether mangosteen is right for you.
