The Effects of a Probiotic Food Supplement in Hyperuricaemia

The overall aim of the project is to determine whether a daily intake of health-promoting bacteria, known as probiotics, with or without a dietary fiber, affects uric acid levels in individuals with elevated levels of uric acid in the blood (hyperuricemia). Additionally, the project will investigate which individuals benefit from this dietary supplement and which do not, based on factors such as gut microbiota composition and function, dietary habits, genetic factors, and inflammatory status. The ultimate goal is to develop a personalized therapy for hyperuricemia. At the beginning of the study, blood samples will be taken to determine uric acid levels and 99 individuals with hyperuricemia will be invited to participate in a 6-week intervention study with daily intake of dietary supplements. To examine the effect of the supplement on various health variables, blood, urine, stool, and breath samples will be collected on several occasions. To better understand the underlying factors of hyperuricemia, questionnaire data and results from biological will be compared between participants with normal versus elevated uric acid levels. Furthermore, different outcome parameters from questionnaires and samples before and after supplement intake will be compared. In addition, various methods for estimating dietary intake will be investigated and compared with each other.
