Reverse Osmosis water is very safe for human consumption.
Reverse Osmosis doesn't remove natural organic minerals from the water but but instead Reverse Osmosis removes contaminants and other inorganic minerals that we don't need.
Also purified water through Osmosis filtration can help to remove harmful bacteria and other contaminants that may be present in the non purified water which could be harmful to humans.
So actually Reverse Osmosis water is actually better for your health than tap water that hasn't been purified through Reverse Osmosis.
