Hesperidin

Common Name: Hesperidin

Overview:

Hesperidin is a water-soluble citrus bioflavonoid. It is the principle flavonoid in lemons and oranges. The skin and membranes of citrus fruit contain higher concentrations of hesperidin than the fruit itself. While hesperidin is found in all citrus fruit, oranges and tangelos contain the highest concentrations of this bioflavonoid. It is a powerful antioxidant and helps increase the activity of vitamin C in the body. Although hesperidin is not an essential nutrient (a nutrient that is vital for life), a deficiency of hesperidin has been linked to an increase in capillary permeability, pain in the arms and legs as well as weakness and leg cramps. In Europe, this bioflavonoid is approved for the treatment of diseases of the blood and lymphatic vessels. This includes hemorrhoids, venous insufficiency, leg ulcers, easy bruising, nose bleeds and helping to alleviate lymphadema following breast cancer surgery.

Benefits

Many studies have been done on the health benefits of hesperidin. Studies have shown that hesperidin, because of its antioxidant properties as well as its ability to strengthen the circulatory system is proving to:

1. Help reduce the swelling of the arm following breast cancer surgery. A double blind study showed a significant decrease in swelling in those who received bioflavonoid therapy compared to those that took the placebo.
2. Improve venous circulation and strength in those who suffer from severe chronic venous insufficiency. This improvement was seen in a double blind study of over 200 individuals.
3. Decrease the healing time of a group of people who suffered from nonhealing leg ulcers
4. Significantly increase HDL-cholesterol while lowering total lipid and triglyceride in the blood. In a recent study, 25 people with elevated cholesterol levels where given hesperidin rich orange juice. One glass of this juice was taken every day for four weeks. This was then followed with two glasses a day for 4 weeks and finally three glasses a day for 4 weeks. The HDL levels of these individuals increased 21% while the LDL/HDL ratio dropped 16%. The folate levels where also seen to rise, a good thing, since folate causes a decline in the levels of homocysteine. Elevated levels of homocysteine are linked to an increased risk of heart attack. This positive effects persisted even during the 5 week washout period when the test participants where asked not to drink orange juice.
5. Improve acute internal hemorrhoids of pregnancy.
6. High blood pressure and act as a diuretic in animal studies.
7. Inhibit the growth of cancer cells in vitro (in the test tube) and in animal studies. In one of these tests the cancer inhibiting effect of dietary several bioflavonoids were tested against each other. The bioflavonoid hesperidin was the most potent.
8. Have significant antiallergenic and anti-inflammatory properties. This was seen in preliminary animal studies. More research is in progress.

Dietary Sources

Citrus fruit

Juice, especially juice with the pulp

Recommended Dosage:

The recommended dosage of bioflavonoids is 500mg twice a day.

Contra-indications

None. Extensive investigations of hesperidin have found it to be non toxic and free of any drug interactions.

Women who are pregnant or breastfeeding should consult a health care provider before using hesperidin.

Drug interactions

None
