Gh8, also known as Gh8 or Gerovital 8, is another PABA and DEAE product from biochemist Robert Koch, DSc. This product provides the same PABA and DEAE complexes as the Gh7, providing the same benefits as the Gh7, enhanced by upgrading with some powerful natural antioxidants and free radical scavengers.
The OPC antioxidants (oligoproanthocyanidins) in the Gh8 are often referred to as Pycnogenol*. The antioxidant properties were discovered and patented by Jack Masquelier, PhD. The OPC extract is from grape seeds. In his research, Dr. Koch has found the grape seed extract to be superior to the pine bark extract because of its higher polyphenol content, containing the gallate esters of the proanthocyanidin, which are not in the pine bark extract in any notable concentration.
The flavanoids (from grape seed extract) along with the flavanoid glycosides (from Ginkgo biloba extract), the silymarin group (from Milk Thistle), combined with the bioflavonoids and cynarine (from artichoke extract), all work synergistically with the PABA and DEAE complexes to feed and protect damaged cells from free radical damage.
