The formula contains the 4 basic alkaline minerals that we need most. The pickling lime is calcium hydroxide which is extremely alkaline. The Magnesium sulfate is nearly neutral as is the potassium chloride. The sodium bicarbonate is mildly alkaline. However, all of the minerals will dissociate in solution and will be easily absorbed.
The calcium hydroxide is so alkaline in its powdered form that it can actually burn skin if left on it for a while. However, when diluted in water along with the other minerals, it is toned down to a safe level.
It took is a few weeks to bring my pH up from disastrously low levels ( 5.4 to 5.6 at one point and 6.8 to 7.0 at the end ).
