R/O is a great source of water! It does however lack minerals. Calcium and magnesium primarily.
If you're concerned about the missing minerals take a quality multi-vitamin or as Diana said get your minerals the best way, through healthy foods.
Water has always been a huge debate in the health food arena. Alkaline, spring water and others all claim to be the fountain of youth. To be honest, it's all hogwash IMO. Drink plenty of water and eat right. Get your minerals and vitamins through the foods you eat. If that ever fails that multi-vitamin is simply insurance. No harm in them regardless of whether we need them or not.
