I tried sprinkling half a teaspoon of calcium carbonate in while I was cooking it (I cook it low and slow after bringing to a boil) along with salt and some coconut oil.
It was just an experiment regarding any phytic acid content (Calcium carbonate being an alkali) and it really made a difference, the porridge got that pleasing lighter colour and really hearty consistency. Whether it 'reacted' with the oats or something, I don't know.
Total calcium addition wouldn't be much as calcium carbonate contains a smaller amount per mg.
