Naringin

What Is It?

A flavonoid compound found in grapefruit, naringin gives grapefruit its characteristic bitter flavor. Grapefruit processors attempt to select fruits with a low naringin content, and often blend juices obtained from different grapefruit varieties to obtain the desired degree of bitterness. Naringin is believed to enhance our perception of taste by stimulating the taste buds (some people consume a small amount of grapefruit juice before a meal for this reason).

Health Benefits

Naringin may be instrumental in inhibiting cancer-causing compounds and thus may have potential chemotherapeutic value.

Studies have also shown that naringin interferes with enzymatic activity in the intestines and, thus, with the breakdown of certain drugs, resulting in higher blood levels of the drug. A number of drugs that are known to be affected by the naringin in grapefruit include calcium channel blockers, estrogen, sedatives, medications for high blood pressure, allergies, AIDS, and cholesterol-lowering drugs. Caffeine levels and effects of caffeine may also be extended by consuming grapefruit or grapefruit juice.

While the effect of naringin on the metabolism of a drug can increase the drug’s effectiveness, it can also result in dosages that are inadvertently too high. Therefore, it’s best not to take any drugs with grapefruit juice unless the interaction with the drug is known. In addition, the effects of drinking grapefruit juice is cumulative, which means that if you drank a glass of grapefruit juice daily with your medication for a week, the drug interaction would be stronger at the end of the week than at the beginning.

  • Ten Drugs Doctors Should Consider De-Prescribing

    Physicians use the word polypharmacy when a patient is taking five or more prescription drugs daily. A recent survey showed that half of women Medicare recipients were taking five or more drugs daily, and 12% of them were taking ten (!) or more. New patients frequently arrive at WholeHealth Chicago carrying bags stuffed like piñatas with prescription drugs and nutritional supplements, the latter recommended by Read More

  • Toxic Metals, Heart Disease, and Chelation Therapy

    In last week’s Health Tip I reviewed the well-researched health dangers of environmental toxic metals (also called heavy metals). They’ve always been a serious health risk, but with the Trump Administration’s recent rollbacks of clean air and water regulations we can expect even more trouble ahead. Statisticians predict an astonishing 160,000 unnecessary deaths over the next decade from the reversals of clean air and water Read More

  • Heavy Metal Toxicity and Your Health

    For those who were otherwise preoccupied that day long ago in high school chemistry, the heavy metals refer to a group of especially dense metals or metal-like substances (called metalloids) found in the environment. These metals–specifically lead, mercury, arsenic, cadmium, and aluminum–can all be absorbed by your body and stored there. Our environment is already quite toxic (Trump’s EPA deregulations aren’t helping) and it’s getting Read More
