Protocol-N infusion has been developed as part of the Cellsymbiosis Therapy concept and was originally produced by the Victoria Apotheke (pharmacy), in Saarbrucken. It contains amino-acids, trace elements and minerals (e.g., glycine, glutamine, taurine, cysteine, carnithine, carnosine, arginine, glutathione, etc.), trace elements and minerals (e.g., zinc, selenium, magnesium, calcium, potassium, etc.) and vitamins (e.g., C- and B-complex). For over ten years, the protocol-N infusion has proven its value in complementary medicine as an effective support for overall cell and mitochondrial performance.

Under certain circumstances it can be individually modified with further admixtures, if prior lab tests have indicated specific deficiency.
