Impact of Supplements on Blood pH?
Q I’ve just read Building Bone Vitality: A Revolutionary Plan to Prevent Bone Loss and Reverse Osteoporosis, by Amy Lanou and Michael Castleman. The writers contend that a high acid diet causes bone loss by leaching calcium from the bones to help neutralize it. The book is so well documented, and the theory so logically explained, that I find it compelling. Since I have been taking Personal Radical Shield along with other supplements for almost 20 years, I wonder what their impact on blood pH is and whether there is any way to ensure my supplement combo is neutral or slightly alkaline?

A It isn’t just food pH—it is food metabolite pH, too. As Durk Pearson & Sandy Shaw mentioned in their potassium bicarbonate interview (see
“Potassium Bicarbonate Supplementation” and the interview,
“Potassium Bicarbonate for Reduced Blood Pressure and Increased Muscle Mass,” both in the April, 2009 issue), loss of lean body mass is caused at least in part by burning protein to produce ammonia to neutralize acids. These acids promote both the loss of calcium and lean body mass—which is why potassium bicarbonate helps to prevent both.
Most organic acids (such as acetic and ascorbic and non-sulfur amino acids) can be metabolized to CO2 and water. One of the biggest offenders in many people’s diets is the phosphoric acid and acid phosphates in soft drinks. Note that the tricalcium phosphate in Durk & Sandy’s three-way calcium complex product is alkaline, not acid.
