NCT01860547

Brief Summary

The study hypothesis is that the bioactive compounds of sea buckthorn berries (Hippophaë rhamnoides), their fractions, and bilberries (Vaccinium myrtillus). have positive effects on lipid and carbohydrate metabolism and will thus reduce the risk of developing metabolic diseases.
