L-lysine is an essential
amino acid which is often deficient in vegetarian diets. L-Lysine may
help prevent glycosylation, the combining of a sugar and protein molecule
accelerated by elevated levels of sugar in the blood, which causes some
signs of aging. Linus Pauling has provided evidence that it may also
help prevent coronary heart disease and atherosclerosis by inhibiting
the accumulation of apolipoprotein (a) and (b) on arterial walls.
