Rutin is POSSIBLY SAFE when taken by mouth in the amounts found in medicine for up to 12 weeks. It can cause some side effects including headache, flushing, rashes, or stomach upset.
Studies have shown that Rutin may also be helpful in combating cataracts, macular degeneration, and free radical damage to the retina. Bioflavonoids are plant pigments that protect the eyes from sunlight damage and are powerful antioxidants that may enhance blood flow to the retina.

I also read online where rutin can release epinephrine into the system, and it did for me, causing heart palpitations every day I took it. The other major problem with this is that it caused constipation.
For adults, the recommended daily amount for vitamin C is 65 to 90 milligrams (mg) a day, and the upper limit is 2,000 mg a day. Although too much dietary vitamin C is unlikely to be harmful, megadoses of vitamin C supplements might cause: Diarrhea.
The HPLC analysis showed that the catechin concentration ranged from 109.98 to 5290.47 µg/g, and the rutin concentration ranged from 12.136 to 483.89 µg/g of apple fruit.
Some of the more common herbs for varicose veins are:
- Cayenne.
- Gingko biloba.
- Horse Chestnut Extract.
- Grape Seed Extract.
- Chromium.
- Butcher's Broom.
Bromelain may cause mild side effects in some people, particularly when taken in high doses. These include: diarrhea. nausea.
Using different formulations together increases the risk of an bioflavonoids overdose. If your condition does not improve, or if it appears to get worse, contact your doctor.
If you need to supplement your dog with vitamin C, the best form is the salt forms of vitamin C, known as mineral ascorbates (calcium ascorbate and sodium ascorbate). Ascorbates are easily absorbed anywhere in the dog's intestinal tract.
: a yellow crystalline flavonol glycoside C27H30O16 that occurs in various plants (such as buckwheat and tobacco) and is used in medicine chiefly for strengthening capillary walls.
Bioflavonoids are antioxidants. You may already be familiar with antioxidants, such as vitamins C and E and carotenoids. These compounds may protect your cells from free radical damage. Free radicals are toxins in the body that can damage healthy cells.
It is likely safe to use citrus bioflavonoids on the skin and to take them orally in small doses for a short time. Not enough studies have been done to say whether it is safe to use for a long period. It is also not known whether it is safe to take by women who are pregnant or breastfeeding.
Rutin, also called as rutoside, quercetin-3-rutinoside, and sophorin is a citrus flavonoid glycoside found in buckwheat (Kreft et al., 1997). The name 'rutin' comes from the plant Ruta graveolens, which also contains rutin.
Quercetin may help protect against heart disease and cancer. Quercetin can also help stabilize the cells that release histamine in the body and thereby have an anti-inflammatory and antihistamine effect.
Unfortunately, the potentially toxic effects of excessive flavonoid intake are largely ignored. At higher doses, flavonoids may act as mutagens, pro-oxidants that generate free radicals, and as inhibitors of key enzymes involved in hormone metabolism.
Quercetin is a highly concentrated form of bioflavonoids found in broccoli, citrus fruits, and red and yellow onions. Foods high in bioflavonoids may help you stay healthy. Hosts of experiments on bioflavonoids have suggested that these key nutrients help increase immune system activation.
Bioflavonoids are naturally occurring substances in plants best known for their antioxidant ability; they work in symbiosis with vitamins to neutralise free radicals in the body.
Citrus bioflavonoids and related substances are widely used in Europe to treat diseases of the blood vessels and lymph system, including hemorrhoids, chronic venous insufficiency, leg ulcers, easy bruising, nosebleeds, and lymphedema following breast cancer surgery.
The flavonoid rutin (RU) is a known antioxidant substance of plant origin. Its potential application in pharmaceutical and cosmetic fields is, however, limited, due to its low water solubility.
Rutin is believed to be especially helpful in preventing recurrent bleeding caused by weakened blood vessels, so it has been used in the treatment of haemorrhoids and varicose veins, helping to prevent blood vessel walls becoming fragile. Rutin is also taken by many as a preventative measure against thrombosis.
Hesperidin, alone or in combination with other citrus bioflavonoids (such as diosmin), is most commonly used for blood vessel conditions such as hemorrhoids, varicose veins, and poor circulation (venous stasis).
What's more, Vitamin P not only works to maintain healthy bones and teeth but it also helps build up the body's immune system. Combating the process in which cells become damaged and defective, getting your hit of Vitamin P can help stop chronic diseases such as cancer and heart disease in their tracks.
Background: Oxidative DNA damage is a known risk factor of head and neck cancer. Antioxidants, such as coenzyme Q10 (CoQ10) and quercetin, a member of flavonoids present in red wine and tea, are thought to play a significant role in protecting cells from oxidative stress induced by reactive oxygen species (ROS).
Quercetin is known for its antioxidant activity in radical scavenging and anti-allergic properties characterized by stimulation of immune system, antiviral activity, inhibition of histamine release, decrease in pro-inflammatory cytokines, leukotrienes creation, and suppresses interleukin IL-4 production.
When taken by mouth: Quercetin is POSSIBLY SAFE for most people when taken by mouth short-term. Quercetin has been safely used in amounts up to 500 mg twice daily for 12 weeks. It is not known if long-term use or higher doses are safe. When taken by mouth, quercetin can cause headache and tingling of the arms and legs.
In this report we show that quercetin inhibits thyroid cell growth in association with inhibition of insulin-modulated phosphatidylinositol 3-kinase-Akt kinase activity. Furthermore, quercetin decreases TSH-modulated RNA levels of the thyroid-restricted gene sodium/iodide symporter (NIS).
Inhibition of COMT activity by quercetin may be one of the mechanisms responsible for promotion of estrogen-induced carcinogenesis by quercetin.
In summary, this investigation demonstrated that 6 weeks of supplementation with 1 g/day quercetin did not affect energy, fatigue, or sleep quality in moderately trained men and women.
Common side effects of quercetin include:
- Headache (oral use)
- Numbness and tingling (oral use)
- Shortness of breath (intravenous use)
- Nausea and vomiting (intravenous use)
- Kidney damage (intravenous use greater than 945 mg/m2)
Quercetin is contained in abundance in apples, honey, raspberries, onions, red grapes, cherries, citrus fruits, and green leafy vegetables [2]. Among vegetables and fruits, quercetin content is highest in onions.
Quercetin has been proposed as an ergogenic supplement due to its capacity to increase aerobic exercise performance [9, 10, 17], because it may increase oxidative metabolism [9]. Moreover, quercetin may also decrease adiposity [1]. However, quercetin's effects on weight gain (WG) differ between studies.
