- Eat vegetarian. Uric acid is often made as a byproduct of the metabolism of certain amino acids that are abundant in animal proteins. Adopting a vegetarian diet will help lower the amount of uric acid in the blood.
- Avoid caffeine. Not only does caffeine stimulate the production of uric acid, but it also dehydrates the body, leading to additional accumulation of uric acid in the blood. People looking to cleanse uric acid from their blood should minimize their intake of coffee, tea and caffeinated sodas.
- Eliminate alcohol. The metabolism of alcohol creates uric acid as a byproduct. It also dehydrates the body.
- Drink large quantities of water. Uric acid is processed and eliminated by the kidneys. Drinking lots of water will keep the kidneys active, which will then cleanse uric acid out of the blood.
How to Reduce Uric Acid With Vitamins
- Take vitamin C supplements. Research has shown that vitamin C is associated with reduced uric acid levels, such as a study published in the September 2008 issue of the Journal of Rheumatology. This study found that men taking up to 500 mg of vitamin C daily had lower serum uric acid concentrations than men who did not. Larger dosages did not result in more significant changes.
- Ask your health care practitioner about the appropriate dosage of vitamin C supplements for you. The Mayo Clinic explains that very high doses of this vitamin can increase uric acid levels. High doses of vitamin C also can cause digestive upset and diarrhea. The Linus Pauling Institute at Oregon State University lists the maximum tolerable amount of vitamin C for adults as 2000 mg daily.
- Eat more fruits and vegetables, as these contain vitamin C. Oranges, grapefruit, strawberries and juices from these fruits are especially beneficial. Cherries also are linked to lower levels of uric acid, according to the Mayo Clinic, and their website recommends adding other dark fruits for a uric-acid-reducing diet, including purple grapes, blackberries, blueberries and raspberries.
- Avoid taking large amounts of vitamin B3 (niacin) supplements, since doses of 300 mg and higher have been linked to increased uric acid levels. The recommended daily allowance, commonly included in multivitamins, is 100 mg.
- Avoid multivitamins that include high doses of zinc, which have been associated with increases in uric acid levels, as shown in a study published in the November 1986 issue of the American Journal of Medical Science. Recommended daily allowance of zinc is 11 mg for men and 8 mg for women.
