Dietary Supplement: Dietary supplement GVG 2
2.670 g/day for 14 days
Other Name: GAVMATINE(TM)
Herniated lumbar discs exert pressure on nerves in the spine leading to pain, numbness, tingling and weakness of the leg, sometimes termed "sciatica". This syndrome affects about 1-2% of the population, usually at the age of 30 to 50 (the prime working years) leading to significant economic impact.
Injuries of nerves can lead to degeneration of the parent nerve cells, the neurons. Recent evidence indicates that herniated lumbar disc exerts mechanical pressure on spinal nerve roots that leads to local ischemia and inflammation resulting in nerve injury (i.e. neurotrauma). This neurotrauma can lead to degeneration of the corresponding nerve cells (dorsal root ganglia sensory neurons and spinal cord motoneurons), resulting in persistent deficits in motor functions, sensation and pain. Enhancing nerve cell survival capabilities (i.e., neuroprotection), therefore, should prove a novel therapeutic strategy for slowing or preventing degeneration of neurons resulting from herniated lumbar disc compression. Yet, in spite of an intensive search, clinically effective and safe neuroprotective therapeutic is not available.
The active ingredient in the dietary/medical food supplement under study was discovered to be an efficacious neuroprotective agent. The original findings, confirmed by laboratories throughout the world, indicate that the active compound is unique as it acts at multiple molecular targets to exert its robust neuropeotective effects.
The active ingredient is found in many plant, fish and meet foodstuffs and is being used and sold as a food supplement and nutraceutical. Its use as a neuroprotective agent is patented and thus, it constitutes an ideal candidate for neuroprotective treatment in herniated lumbar disc and other spine skeletal pathologies causing nerve compression.
The safety of the dietary supplement under study was clearly demonstrated in a recent clinical trial. Results of the trial demonstrated improvement in the general health status and indicated efficacy in alleviating symptoms in participants with herniated lumbar disc and other spine skeletal pathologies causing nerve root compression.
The present study is randomized, double-blind, placebo-controlled trial designed to ascertain the therapeutic efficacy of the dietary supplement in participants with herniated lumbar disc causing nerve damage symptoms. The study is being conducted in two medical centers in Israel. Eighty participants are presently being recruited and are screened under strict inclusion and exclusion criteria. Eligible individuals are invited to participate after signing a detailed informed consent prior to beginning of the study. The participants are being assigned randomly to receive either the dietary ingredient or placebo in a blind fashion whereby neither the treating physician nor the participant are aware of the type of treatment.
