Naringin

Naringin Benefits

There are many reasons for you to consume more naringin:

Citrus bioflavonoids may block the formation of cancer-causing molecules, according to Dr. Richard Beliveau in Canada. Beth Israel Deaconess Medical Center recaps many ways naringin may benefit health in recent medical research studies. The site says that bioflavonoids like naringin have been used in Europe to treat blood vessel and lymphatic system disease in Europe for many years.

That's why breast cancer patients may benefit from naringin and other bioflavonoids after surgery. The bioflavonoids may help to reduce swelling and reduce fluid collection. Importantly, breast cancer patients taking tamoxifen shouldn't use bioflavonoids without doctor approval. Supplements containing tangeretin are contraindicated for tamoxifen-users.

People with high cholesterol, high blood pressure, hemorrhoids, allergies and other conditions may benefit from naringin supplements, according to recent Beth Israel Deaconess research studies. The Journal of Science of Food and Agriculture also reports that studies suggest narigin may help reduce blood fats and high cholesterol.

Naringin’s role in bone health is part of a current human trials study. According to a study reported by PubMed in 2010, naringin helped to improve the bones of mice without ovaries.

Other people use naringin as part of a diabetes-management program. According to "There Is a Cure for Diabetes: The Tree of Life 21+ Day Plan" by Gabriel Cousens and David Rainoshek, narigin, quercetin and hesperidin help to avoid cataracts in diabetic patients. Research published by PubMed also reports possible benefits of naringin supplementation for diabetic people. Eating grapefruit and consuming naringin may help you lose weight, according to research published by the National Institutes of Health.

Naringin Drug Interactions

Discuss how often you eat citrus fruits like grapefruits with your doctor. Naringin’s ability to affect how your body uses some drugs is well-documented. According to previous research published by the National Institutes of Health, how your body metabolizes naringin affects the absorption or blockage of other drugs you take.

According to the Human Metabolome Database, naringin inhibits cytochrome 450 enzymes along with CYP3A4 and CYP1A2. Cytochrome 450 enzymes work in the catalyzing oxidation of organic molecules like steroids and blood fats, toxic chemicals and drugs.

For this reason, naringin’s potential to interact with prescription drugs or other supplements should be discussed with your doctor. The following drugs are known to interact with CYP3A4: sertraline (Zoloft), ritonavir (Norvir), benzodiazepines, triazolam (Halcyon), alprazolam (such as Xanax) and others.

Studies of naringin conclude that it inhibits the body's ability to use some beta blockers, such as talinolol. Other studies show that narinigin decreases the body's ability to use fexofenadine, an antihistamine drug, according to "Drug Transporters" by Martin F. Fromm and Richard B. Kim in 2010.

Naringin Supplement Interactions

Use care when consuming grapefruit or naringin supplements if herbs and other supplements form part of your daily regimen, according to “Meyler’s Side Effects of Herbal Medicines” by Jeffrey K. Aronson. The author says that six to eight glasses of grapefruit juice a day, or the equivalent amount of naringin supplements, may interact with CYP3A enzymes.

Naringin Side Effects

Other than potential drug interactions cited above, taking naringin is generally considered safe in reasonable amounts. Side effects from consuming grapefruits and grapefruit juice in excessive amounts may cause mild stomach upset or loose stool.

Naringin Dosage Recomendations

• As a teaching hospital affiliated with Harvard Medical School, Beth Israel Deaconess recommends up to 500 mg of mixed citrus bioflavonoids per day in healthy people.
• According to “Chinese Herbal Drug Research Trends” by Felix M. Ching, naringen supplement levels of 400 mg per day help lower blood lipid levels. The author says that naringen supplementation seems to support better bone health and protects the body’s lipid balance.
• Prolonged use of up to 1,250 mg/day of naringin in a Chinese study of rats showed no negative affects. Be aware that animal studies and human studies do not always get the same results.

If you’re taking prescription drugs or other supplements, ask your doctor about the best dosage of naringin for you. Some supplements, like St. John’s Wort, also affect the cytochrome P450 enzymes.
