We are currently observing slow but constant progress in extension of human life due to many factors (including achievements in conventional medicine) but the percentage of our lives spent in good health is getting smaller.
In December 2013 edition of a scientific journal Cell, a group of scientists (led by David Sinclair, a professor of genetics at Harvard Medical School), published data suggesting that not only is extension of life possible but we can also do something to improve its quality and even reverse aspects of aging.
Researches point to loss of communication between the genetic material of nucleus and mitochondria as the main reason of aging. It seems to be caused by dropping level of NAD+ also observed with aging.
It was shown that supplementation which raises the level of NAD+ inside proper compartments of our cells, may fix the problem in communication between nucleus and mitochondria and improve the effectiveness in energy production, as well as increase the number of mitochondria in our cells. Better metabolism may be visible as reversal of aspects of aging.
Because NAD+ itself does not cross cellular wall it cannot be used as a supplement. The only scientifically proven dietary supplement (available since 2013) which can efficiently raise the level of NAD+ in our cells is Niagen.
