What is the salivary cortisol test?

This simple test measures the cortisol levels in your body. It’s simple and painless to do! The Adrenal Stress Index (ASI), conducted through saliva, is the preferred method for assessing adrenal function. It’s widely recognized as a noninvasive and reliable test for measuring cortisol levels.

Four saliva samples are taken at specific times and then shipped to the lab for analysis. To collect the sample, you place a swab in your mouth and wait a few minutes until it’s saturated with saliva. We recommend you make an appointment with your dietitian to understand the results.


What is cortisol?

Cortisol is a hormone produced by your adrenal glands. Known as the stress hormone (fight-or-flight), cortisol aids in stress response and supports various bodily functions, including:

  • Combatting infections.
  • Regulating blood pressure.
  • Controlling blood sugar levels and metabolism, which affects how your body converts food into energy.

While most cortisol is bound to proteins in the blood, some remains “free” and can be found in urine and saliva.


What health problems are linked to elevated or depressed levels of cortisol?

Cortisol is a key determinant of wellness. In our fast-paced, stressed-out world, we provide nutrition therapy to so many who experience overload in their bodies. This can affect several functions, including:

  • fertility
  • gut health
  • cardiovascular health
  • weight gain
  • chronic fatigue and insomnia
  • thyroid disorders
  • the immune system
  • blood sugar imbalances and diabetes

The most effective way to control cortisol levels is by mastering stress management techniques and optimizing your diet.


Cortisol and Diet Therapy

As functional dietitian nutritionists, we can use cortisol tests to help identify underlying problems. Systematic inflammation causes elevated cortisol levels, so we prioritize giving our patients individualized anti-inflammatory diets. With modification, moderation, and by implementing sustainable changes to your diet plan and lifestyle, you can get your cortisol levels back under control and begin to heal.

Our goal is to empower you with the tools you need to make sustainable diet, nutrition, and eating behavior modifications to improve your health status. 

We can’t wait to get started!
