Gout
Vitamin C
Supplementing with vitamin C might reduce the risk of gout attacks, as it appears to help reduce uric acid levels.Dose:
0.5 to 8 grams dailyVitamin CIn one small study, people who took 4 grams of vitamin C (but not lower amounts) had an increase in urinary excretion of uric acid within a few hours, and those who took 8 grams of vitamin C per day for several days had a reduction in serum uric acid levels.1 Thus, supplemental vitamin C could, in theory, reduce the risk of gout attacks. However, the authors of this study warned that taking large amounts of vitamin C could also trigger an acute attack of gout by abruptly changing uric acid levels in the body. Another study showed that taking lower amounts of vitamin C (500 mg per day) for two months significantly reduced blood levels of uric acid, especially in people whose initial uric acid levels were elevated.2 For people with a history of gout attacks, it seems reasonable to begin vitamin C supplementation at 500 mg per day, and to increase the amount gradually if uric acid levels do not decrease.
Quercetin
In test tube studies, quercetin, a flavonoid, has inhibited an enzyme involved in the development of gout.Dose:
Refer to label instructionsQuercetinIn test tube studies, quercetin, a flavonoid, has inhibited an enzyme involved in the production of uric acid in the body.3 In a double-blind trial, supplementation with 500 mg of quercetin once a day for 4 weeks significantly decreased blood levels of uric acid by an average of 8% in men with uric acid levels in the high-normal range.4 Decreasing uric acid levels may help prevent gout attacks.
