Effect of Prebiotics on Hyperuricemia
Study Details
Study Description
Brief Summary
Hyperuricemia is a major risk factor for many chronic diseases. Recently, dysbiosis of gut microbiota has been reported to play an important role in the pathogenesis of Hyperuricemia. Animal studies have demonstrated that administration of prebiotics help delay the progression of Hyperuricemia through several mechanisms. This trial aims to examine its protective effect in humans.

Detailed Description
Hyperuricemia is a major risk factor for many chronic diseases. Recently, dysbiosis of gut microbiota has been reported to play an important role in the pathogenesis of hyperuricemia. Animal studies have demonstrated that administration of prebiotics help delay the progression of hyperuricemia through several mechanisms such as reduction in endotoxemia, and enhanced production of short-chain fatty acids.
However, whether administration of prebiotics also has a protective effect in subjects with Hyperuricemia remain unknown.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Dietary Supplement: anserine Subjects are instructed to take one capsule of anserine daily for a total of 3 months |
Dietary Supplement: anserine
During the study period, subjects are instructed to take one capsule of anserine daily for a total of 3 months. Aside from the prebiotic supplement, all participants are instructed to continue their normal routine and not make any changes to their exercise habits but reduce purine intake.
|
| Experimental: Dietary Supplement: Sunflower peptide Subjects are instructed to take one capsule of Sunflower peptide daily for a total of 3 months |
Dietary Supplement: Sunflower peptide
During the study period, subjects are instructed to take one capsule of Sunflower peptide daily for a total of 3 months. Aside from the prebiotic supplement, all participants are instructed to continue their normal routine and not make any changes to their exercise habits but reduce purine intake.
|
| Placebo Comparator: Dietary Supplement: Placebo control Subjects are instructed to take one capsule of placebo daily for a total of 3 months |
Dietary Supplement: Placebo control
During the study period, subjects are instructed to take one capsule of placebo control daily for a total of 3 months. Aside from the probiotic supplement, all participants are instructed to continue their normal routine and not make any changes to their exercise habits but reduce purine intake.
