Water within cells, particularly around organelles like mitochondria, may exist in a fourth, structured form.

“A lot of people who are interested in structured water as it relates to biological function, have I hypothesized or like to debate rather whether or not in the body water is not just present in its liquid form or gaseous form. We know it's not present in its solid form unless you gulp down some ice cubes, for instance. But, There is a cohort of people out there, including some fairly accomplished scientists that believe that within the body, the organelles of our cells act as a substrate for water to exist in this fourth form, this structured water form.”
