Follow this link to the details:
Kaqun water helps to increase oxygenation BUT it is not high in electrolytes (minerals). People who are already low in electrolytes may not feel like drinking more water since they will be diluting their minerals even further. Kaqun water should not be your only drinking water. It is important to use other water containing minerals or add sea salt or celtic salt to your water and food to improve mineral status along with drinking Kaqun.
