Ok, I have found an odd thing in several of my recent bowel movements.

I release normally, but have found sort-of cylindrical white objects, which crush into a kind of white chalky powder when pressed. What do people think they are? What are they from? What damage might they cause and why are the coming out?

Im trying to be healthy, juicing, good diet. My supplements are, lecithin, cal mag zinc by solaray (I dont really eat enough dairy / high calcium foods), iron on non calcium days and plenty of organic fruits and veg. Will be starting the drink next week when my kelp arrives.

Any advice really appreciated!
