Citrus Naringin is a type of flavonoid, a water-soluble pigment, found in grapefruits. By itself, it has little nutritional value, other than being responsible for giving grapefruit its bitter flavor, and possibly enhancing one’s sense of taste. As a dietary supplement, however, Citrus Naringin has a wide range of benefits.
Citrus Naringin appears to interfere with the activity of several enzymes that are responsible for the breakdown of certain nutrients in the intestines, along with many types of drugs, resulting in higher levels of those substances in the blood. As such, Citrus Naringin is used to enhance the effectiveness and increase the half-life of several supplements and related substances, such as caffeine.
How much Citrus Naringin should I take?
Most studies have shown that a dose of 25 milligrams of naringin is enough to increase the bioavailability and half-life of certain nutrients and/or drugs consumed with it.
What forms of Citrus Naringin are available?
The main source of Citrus Naringin is pure grapefruit juice. However, many types of grapefruit juice are either blended with other juices, or use grapefruits that have low naringin levels, to help remove bitterness and improve taste. Naringin supplements are also available, and are sold in pill, liquid and capsule form.
What can happen if I take too much naringin? Are there any interactions I should be aware of? What precautions should I take?
Because naringin can alter the metabolism of certain drugs so that they remain in the bloodstream longer, taking naringin supplements can result in higher-than-expected levels of those drugs in the blood, which may cause a variety of unwanted side-effects. As a result, patients should not take any drugs with naringin or grapefruit juice without first consulting a licensed health care provider. In addition, the effects of taking naringin and/or drinking grapefruit juice are cumulative; the more naringin that is ingested, the greater its interaction with certain drugs and other nutrients.
Among the drugs known to be affected by naringin are calcium channel blockers; estrogen supplements; sedatives; high blood pressure medications; and cholesterol-lowering medications. As always, make sure to consult with a licensed health care provider before taking naringin or any other herbal remedy or dietary supplement.
