SKU: M250 Category:


Electrical Stimulation Direct Current SIS Technology


The Low Intensity Direct Current (LIDC) SIS technology can be applied to generate a low intensity electron flow for general body antioxidant enhancing effects.

The SIS algorithmic software skin electrical resistance monitoring technology can also be utilized for non medical, general health and wellbeing applications such as hydration monitoring.

The M250 shares technologies from the SIS development medical devices.

Electrical Stimulation Direct Current SIS Technology

Free radicals are the products of normal cellular metabolism. A free radical is an atom or molecule containing one or more unpaired electrons and capable of independent existence. The odd number of electron(s) of a free radical makes it unstable, short lived and highly reactive. A steady flow of electrons has been shown to appear to act as a highly potent antioxidant.
