Niacin has the property of causing the small blood vessels to increase in size. These are the capillaries. Now, capillaries are often so small that the blood cells pass through them in single file. It is the capillaries that take care of the vast majority of all the cells in the body. You have large arteries near the heart, and they get smaller and smaller as they extend from the heart. But, at the end of every well-sized artery is a very large network of capillaries. They all start from the heart — but at the end of the line they are tiny, tiny capillaries. Just take an arbitrary number for the number of living cells in your body — perhaps one billion. The exact number is not critical for this purpose. Now, the question is: “How many of those billion cells are within a fraction of an inch away from one of the large arteries so that they can get rid of toxins directly into that artery, and to get nutrients from that artery?” I don’t know, but I’ll guess that it is less than 20% of al
