Shielding cells from the ravaging effects of oxygen free radicals is one route to a long cellular Youth; maintaining and repairing cells after the free radicals that pierced that shield have done their inevitable dirty work is another.
The most understood way that free radicals damage cells is through attacks on the DNA, the cell proteins, and the cell membranes. Fatty acids and phospholipids are specific fat like compounds that all of our cell membranes are composed of to a significant extent, and therefore they are needed in order for the cells to maintain and repair their cell membranes.

Phosphatidylcholine (PPC) is a phospholipid that has been found to be especially useful in repairing and stabilizing the cell membranes of liver cells. Your body makes PPC, but it is very energy-demanding, and studies of people with existing liver disease suggest we don’t make enough of it for maximal health of our liver cells.
Taking PPC is a particularly good idea if you drink alcohol, a major liver toxin. In fact, Dr. Charles Leiber, at the Mount Sinai School of Medicine in Manhattan, has shown that baboons consuming alcohol along with PPC supplements for several years were significantly less likely to progress to fibrosis and cirrhosis of the liver than those baboons drinking alcohol and not getting PPC.

Phosphatidylserine (PPS) is a naturally occurring substance that is essential to all cell membranes, but is found in particularly high concentrations in the cell membranes of the brain.
Clinical studies have shown that PPS works by supporting certain brain functions that decline with age, possibly by enhancing neurotransmission by neurons and stabilizing neuronal cell membranes.
Until recently, PPS was available only from animal sources (their brains), and was found in trace amounts in commercial lecithin, but a plant source of PPS has now been found. Read the rest of this entry »
The role of omega-3 fatty acids in enhancing youth is basically twofold. First, several studies have shown that high intakes of omega-3 fatty acids seem to decrease the incidence of heart disease.
This was first described in 1978, when John Dyerberg published a paper demonstrating that the fish that Eskimos consumed were very high in omega-3 fatty acids.
He had begun this study because it was very puzzling that Eskimos had much lower rates of certain types of heart disease than people in the continental United States, despite the fact that their diets consisted almost exclusively of meat and fish.
Since then, several papers have suggested that omega-3 fatty acids decrease heart disease—but the question remains as to just how they do it. Several studies have shown they do it by blocking the synthesis of a special enzyme called thromboxane A2 (TAX). One of the jobs of TAX is to cause the small cells in our blood known as platelets to clump together whenever we cut ourselves. Read the rest of this entry »
