Body pH Changes

by Mary

Hi there.

I was wondering if you could tell me if your body pH changes throughout the day? I have been very sick and I am trying to maintain a healthy balance but mine keeps changing. Any advice would be a blessing.

Thank you!


Hi Mary,

The pH of your urine and saliva definitely does change throughout the day. We are at our most acidic around 2am and our most alkaline at 2pm. This is a natural, normal part of our physiology.

To figure out your body pH:

Test your saliva first thing in the morning when you get out of bed - before you put anything in your mouth (food, water, toothbrush). Your saliva pH should never be below 6.8. If it is, it means that your alkaline mineral reserves are way too low and the body does not have the minerals necessary to properly process food.

Check the pH of the first and second urine of the day. The first urine reflects the acid load from the day before. The lower the number the higher the acid load. The second urine should be just slightly acid (about 6.8), a sign that the acids from the day before have been flushed out. If not, it means that your kidneys are overwhelmed and your body is burdened by excess acidity - there are too few alkaline minerals left in the body to increase the pH.

Check your saliva pH 5 minutes after eating something at breakfast. This number should be higher than what it was when you woke up. Ideally it should be 8.5 or higher after breakfast. If not, this also tells you that your alkaline mineral reserves are dangerously low.

Check your urine pH between meals as well. It should be in the range of 7.0 to 8.5. After a meal, the stomach secretes hydrochloric acid to digest the food. This stimulates the pancreas to make the alkaline compound sodium bicarbonate. The urine pH 1 to 2 hours after eating should show that enough sodium bicarbonate is being produced, and register as alkaline. If your pH is less than 7, you have too much acid waste and are more likely to have symptoms of acidosis.

Hope this helps.
