You can now easily and effectively test the pH for your body just like you would the pH in a pool, fish tank or soil!

pH test strips are a single plastic strip with indicator squares on one end that, when activated, show your body’s pH levels.  

Brightcore ® pH Test Strips give you results in just 15 seconds and conveniently allow testing by saliva or urine. Our test strips use a three-color system on a single plastic strip which increases accuracy and ensures no color bleeding as you may find with the pH paper roll strips (litmus paper).

What is pH and why is it important?

pH ( potential hydrogen) is how your body 's acidity and alkalinity are measured. The pH scale goes from 0-14, 0 being extremely acidic and 14 being very alkaline. A reading of 7.0 to 7.4 is optimal balance, with less than 7 indicating an acidic environment and greater than 7 an alkaline environment. A slightly higher alkaline level in the body has been linked to better overall health whereas an acidic level puts you at a higher risk for many health issues.

When your pH is balanced, your body is able to effectively absorb and utilize important vitamins, minerals and nutrients from your diet and supplements. By managing your pH range and moving toward a more alkaline environment, you will ensure not only better health, but also that you are getting the best possible results from your nutritional program.

pH is Logarithmic / One point is a huge difference:

Keep in mind when checking your results on the chart that pH works in a different way than a regular number scale. pH works logarithmically, which means for each point you drop away from or above 7.0, you’re actually experiencing a 10x decrease / increase in your pH!

This means just one point can make an incredible difference. As an example, someone with a pH of 6.0 is ten times more acidic than someone with a pH of 7.0. Someone with a pH of 5.0 is 100 times more acidic, someone with a 4.0 is 1,000 times more acidic and so on. 


As you can see, just a slight change can mean a world of difference. Thankfully, Brightcore pH strips give you the most accurate reading possible! 

Three color test strip for increased accuracy: 

Brightcore® pH Test Strips are made and calibrated specifically to test urine or saliva.* 


Because the reagents (the color squares) are affixed to a plastic strip it makes them extraordinarily convenient. There’s no paper, no bleeding, and no mess. In fact, Brightcore® pH Test Strips are one of the very few test strips on the market that can pass through a urine stream without having the reagent bleed, making them exceptionally easy to read.

Brightcore® pH Test Strips three test color system has two squares using two different pH reagents. The top reagent is more sensitive to higher pH ranges (7.0 – 9.0), the middle reagent is sensitive to the neutral range (6.0-7.0) and the bottom reagent is more sensitive to lower pH ranges (4.0 – 6.00). This combination gives you an ideal reading of your pH level.  

Simply put, our three test color system accurately measures a narrow pH range in .25 pH increments, so you’ll get a clear and concise reading of exactly what your pH is.   

Why choose Brightcore pH test strips over the pH test paper rolls (litmus paper)?

If you are going to spend the money and time to test you pH, then I am sure you would like to ensure you are getting the most accurate reading. If that is the case, we recommend using our Brightcore® pH Strips over others and this is why:

Brightcore® pH Test Strips:

  • Do not bleed as litmus paper will 
  • Are Medical GradeResults in only 15 seconds – Urine or Saliva 
  • Come in single plastic strips for ease of use and convenience 
  • Have a clear and concise, 3 color test system for the highest accuracy  


For unopened product: store in a cool, dry place out of direct sunlight. Once opened, store TrueFood in your freezer or refrigerator to maintain potency of the probiotics. 


If Testing By Saliva: 

As soon as you wake up, before anything else, test the pH of your saliva. Simply cover the three color squares in saliva (using a spoon is a common best practice for this) and wait at least 15 seconds for an accurate reading.

Important: Do this before you put anything else in your mouth! Don't clean your teeth, drink, eat or anything else. 

Compare your color squares against the ones listed on the included chart and find the closest match. Write down the pH level associated with your color match so you can keep track. 

If you want to test throughout the day, ensure you wait a minimum of 2 hours after putting anything in your mouth (water, food, etc.) before testing to get a more accurate reading. 

If Testing by Urine: 

It is important to ensure when testing urine that it is your second use of the bathroom for the day. Simply ensure you cover the three color squares with urine and wait at least 15 seconds for an accurate reading. 

Compare your color squares against the ones listed on the included chart and find the closest match. Write down the pH level associated with your color match so you can keep track. 

Why are there three colors on the test strip?

The three colors are used to obtain an average between the colors that coincide with the chart on the back of the pH strips.

How do I compare the strip to the chart on the bottle?

Holding the strip in your left hand and bottle in your right, hold the strip against the chart with the white handle part of the strip on the left side of the bottle.

How often should I test my pH?

pH testing with strips / rolls will not give a completely accurate result as a one-off test.To get truly accurate and meaningful results , you need to test and track changes overtime.

We recommend testing twice daily for 7 days in a row with either Saliva or Urine following the instructions we provide. You will then combine all of your results , divide by 7 and this will give you the most accurate result of your true pH level. 

If you are on an alkalizing nutritional program, you can continue testing this way for 30+ days to see your body becoming more alkaline in real time!   

When should I test my pH?

When testing urine: Test the first and second urine of the day and use the average. 

When testing saliva: Wait 2 hours after eating.

What do the results of the pH test mean?


The saliva tells us how effective your body is at dealing with the acidic foods you may have eaten the day and night before, and the overall ability of the body to respond to your lifestyle. It shows us how well the salivary glands (as well as the stomach, pancreas, gallbladder and liver) are performing in dealing with excess acidity from diet.

Saliva Goal pH: you want this pH to be at least 6.5 and ideally above pH 7.0.


The first urine of the day is the pee that has been stored in your bladder overnight and is a track record of the stored alkaline buffers you have that have been working while you sleep to neutralise the acids you've consumed and that your body has created overnight through bodily functions (such as metabolism).

Urine Goal pH: Your second urine should be at or above pH 7.0

If you are below pH 6.5 then we highly recommend you follow an alkalizing diet/ program to bring your body to a more alkaline state.
