Testing the Body’s pH (Acid/Alkaline) Level

The human body functions best in a slightly alkaline environment. The optimum alkalinity varies in different parts of the body: The blood and tissues want to be slightly alkaline; the lower bowel, slightly acid; urine, slightly acid to neutral; saliva varies. Urine and saliva pH (acid alkaline measurement) can be easily checked and can be a somewhat accurate indicator. The most accurate measurement of the pH balance in the body is blood pH.

Today there are many sources recommending the measurement of urine and saliva pH using paper strips that change color according to the amount of acid in the fluid. The dilemma has been that every source seems to recommend a different optimal pH range for both urine and saliva, and levels fluctuate during any 24-hour period.

According to Robert O. Young, Ph.D., D.Sc., the normal pH range for Saliva is 6.8-7.2, but it can range between 6.0 and 7.2. It is best to test saliva at least two hours after eating or drinking any fluids—first morning saliva is probably easiest.

The normal pH for urine is 6.8-7.2 but can range from 4.5-8.0. The urine pH will normally be lowest in the morning and peak in the evening.

Checking pH can be a useful tool for someone who wishes to assess the general pH balance of the body as a preventive tool, and can be especially key to someone who is ill with cancer or any other health challenge. It can also be used to verify results of an alkalizing program over time.

If saliva and/or urine pH are consistently outside the normal range, it is best to address this issue through nutritional supplementation and dietary changes—and to assess other lifestyle habits. See a healthcare practitioner if there are health concerns.
