Can germs become resistant to Grapefruit Seed Extract as they can to antibiotics?
There is no evidence that any type of micro-organism has ever developed a resistance to Citricidal® or Nutribiotic grapefruit extracts. In fact it is believed that such resistance is not possible because of Grapefruit Seed Extract’s mode of activity. Because Grapefruit Seed Extract actually disrupts the cytoplasmic membrane, changes in genetic make-up in the pathogenic organism would be irrelevant. What is still not known is how Grapefruit Seed Extract can be effective against viruses, inasmuch as a virus has no cell membrane of its own.
