Basic additive for drinking water

The invention discloses an alkaline additive system of drinking water, which consists of KOH and NaOH to modulate alkaline drinking water, wherein one part of dense alkaline additive solution is diluted into one ounce composition by several fractions of distill water; the scale of composition is 50-95% KOH and 5-50% NaOH; 75% KOH and 25% NaOH in one ounce bottle (diluted by distilled water) is loaded by small drop-lid to provide convenience to add the additive to normal glass of drinking water, which is easy to obtain the alkaline drinking water.
