Unique value with immediate benefit in mental clarity, mental stamina, and feeling of being "clean" and balanced. Seems to store water in my body and only release when my body has made full use of water. Eg I urinate fairly dark urine even after maybe 2 litres of treated water each morning. Takes maybe 2 hours before I urinate a second time.
Contrasting with frequent light coloured urine soon after drinking water.
Pretty good indicator that water is penetrating cells. Filling them fully, then taking on toxins fully before being excreted.
Also I get a subtle and enjoyable boost of energy that feels smooth and natural
