Have you heard of those little alkalinizing drops & what do you think of them? People report they surely change the color on the little ph papers (mine is way too acidic) & some say they help with weight loss.
Alkaline drops and even alkaline waters contain either caustic hydroxides, or carbonates. Neither one is healthy. The first thing they will come in to contact with is the stomach acid either neutralizing or reducing stomach acid. This will lead to a number of health issues such as poor protein digestion, lower nutrient absorption, increased Candida growth, etc. Here are a posts on the subject.
As for the pH papers it is important to understand that urinary pH and salivary pH DOES NOT reflect blood pH. If you want to know your blood pH you need a blood test. But even blood pH can change in a matter of seconds. Just look at what happens when you hyperventilate. It causes the pH to rise excessively (go alkaline) and you pass out from the lack of blood flow to the brain.
