Water Soluble Flavonoids

Methods for obtaining a stable solution to enhance bioavailability of flavonoids (e.g. Taxifolin/Dihydromericetine, or Quercetin) include the following steps: -mixing, in predetermined amount, the flavonoid with Citric acid, obtaining a first mixture, grinding the first mixture for 10-15 minutes, mixing the first mixture with a predetermined amount of L-Arginine, obtaining a second mixture, grinding the second mixture for 15 minutes, and either adding water to the second mixture, thereby obtaining the stable solution, or storing the second mixture for further use. Exemplarily, there are disclosed specific weight amounts for each ingredient of the solution.
