hello justy
it is mentioned in the document. If you do a search (Edit -Find) with 'liposomal', it should point you to it.
And here is the result:
Superoxide Dismutase and Catalase
The best success has been reported with injections of liposomal-encapsulated SOD. But due to the cost and our desire to avoid injections, we have to look to an oral source. But oral supplements are said to be completely destroyed in the intestines. There is a sub-lingual lozenge available, which would send free SOD more directly into the blood stream, but the dosage is very low.
There is a product manufactured by a company called Biotec which is supposed to increase the body's production of SOD, catalase, and GSH-Px. The tablets, called "Cell-Guard", contain a concentrate of genetically-engineered wheat sprouts, and are marketed as the best alternative to injections. Literature from Biotec describes the results of several studies on which they base their claims. The first is a study of the effect of the Biotec tablets on the erythrocyte SOD levels of ten healthy, elderly subjects. After about two weeks, the subjects showed an average 230% increase in erythrocyte SOD levels; the minimum increase was 32%, the greatest 730%. Six tablets were taken daily upon rising, one hour before breakfast, for the first two weeks, three daily for the second two weeks.
Another study showed increases in serum SOD levels averaging 40%, increase in catalase 60%, and serum glutathione peroxidase up 78% in the age range 41-50. Placebos showed virtually no increase. The company literature also cited more subjective studies indicating reduction of pain and increase in overall feeling of well-being among almost all customers surveyed by participating physicians.
Since we have no other good oral means of improving SOD levels and catalase levels, this "Cell-Guard" product seems worth trying. Take according to directions, which is upon waking and an hour before eating the first meal. Eight glasses of water per day is important.
