Potassium Phosphate (Mono / Di / Tri)

Debatable Keto Ingredient

What is Potassium Phosphate?

Potassium phosphate refers to various inorganic salts of potassium (K+) and phosphate (PO43−). It includes monopotassium phosphate, dipotassium phosphate, and tripotassium phosphate. Phosphates are obtained from naturally occurring phosphate rock. Potassium phosphate is commercially derived from the neutralization of phosphoric acid with potassium hydroxide or potassium carbonate. Dipotassium phosphate can be found on many jar and packet labels due to its use as a food additive. Its role here is to lower the acid levels in processed foods, along with lowering the sodium levels in low-sodium cheeses. It is also used as a stabilizer in non-dairy creamers to prevent coagulation.

Keto Status?



Low carb, but synthetically produced in a lab and linked to potential health risks (see side effect below). As a workout supplement, phosphates can play a role in the production of ATP (adenosine triphosphate), which is a high-energy molecule that your body requires for energy. Provides health benefits including:

  • Increased energy in workouts
  • Helps increase your intake of potassium

Possible Side Effects From Ingesting Potassium Phosphate?

Can worsen kidney disease
Can worsen edema
Can cause digestive issues

*Phosphate additives in dietary sources are potentially problematic for people who have conditions that require them to limit their phosphorus levels. The type of phosphorus found in disodium phosphate and other food additives is more easily absorbed than the kind that is naturally found in food sources, so it can potentially rapidly increase phosphorus levels too much in people who eat a lot of processed foods containing these additives.
Can cause headaches, digestive issues, confusion, and dizziness in some.

I Heart Keto Mart Rating Guide

I Heart Keto Mart rates all ingredients through a “keto diet” & “low carb diet” lens. As an example, peas would be rated as “Acceptable” on a non-keto healthy diet; however, due to their carbohydrate level, we rate them “Objectionable”. We also rate all sweeteners that typically cause a rise in blood sugar and insulin levels as “Objectionable”. If you prefer a natural sweetener, like honey, over a sugar alcohol like erythritol, you may not agree with our “Objectionable” rating. I Heart Keto Mart rates all ingredients based first and foremost for those that have a sugar/carbohydrate addiction. Ingredients are rated for those who must moderate if not completely abstain from any sugars. If you have questions about this, please refer to this article: Why Some Whole Foods Are Not Keto Friendly


I Heart Keto Mart is not a health care provider. We are an online keto educational site that shares keto approved products and low carb products and defines and rates their ingredients. I Heart Keto Mart’s hope is that our viewers will educate themselves on “all things ingredients” so they can easily identify keto approved ingredients and eliminate or greatly restrict unacceptable keto ingredients. I Heart Keto Mart is the best online keto store and online low carb store with 1000s of products and an informative blog that shares keto articles and keto recipes, interviews keto coaches and keto product manufacturers and so much more.  We are keto affiliates and each of the keto approved products we rate is linked to the vendor’s site where the product may be purchased. I Heart Keto Mart may earn a small commission from these sales. Amazon is one of these affiliates.
