It needs to be only small enough to swallow. It is easily reduced when it
hits the very strong acid in the stomach. Most "absorption" is by such
chemical reaction and not a mechanical entry into the blood if it is small
enough. For example, some fibers can be ground as fine as you want and
they still pass from the gut because they are not very subject to the
chemistry required for absorption. Some retail calcium pills come from
shells.
