Dr. Gerson felt strongly about the use of increased amounts of niacin (Vitamin B3) in cancer patients from the beginning of treatment and without too much interruption. However after using 50mg six times a day for four to six months, it should not be diminished too fast. Niacin helps to bring back sufficient glycogen into the liver cells. It also helps in protein metabolism, acts to open small arteries and capillaries (of course it would be discontinued with any bleeding problems.) It raises electrical potential in cells. You can find more information on page 209 of A Cancer Therapy: Results of Fifty Cases.NIACIN may also assist liver metabolism and lower blood cholesterol levels.
