My noise in the ears is less what I want to count the quercetin. In addition, an increase in energy is recorded. The medical practitioner Lorenz Gesswein writes in his book "new strength" about the beneficial effects of quercetin on the mitochondria (ATP-producing power plants in the nucleus). They would also have the Bromelain, an enzyme of the pineapple, which is used against inflammation (Wobenzym). Unbeatable in price and quality.
