Maintaining nitric oxide for optimal heart and brain health requires both dietary nitrate from plant-based foods as well as friendly nitrate-reducing bacteria on your tongue.  

Nitric oxide is as important as the oxygen you breath.  It is a vital molecule produced in your body that helps blood vessels dilate to promote blood flow to the brain, lessen the stress to your heart, and improves exercise performance as you age.  

MyFitStrip is a patent-pending saliva test strip to help detect for the presence of the oral microflora or probiotics that are necessary to convert dietary nitrate to nitric oxide.

Your wellness journey starts here.

MyFitStrip 

Know your nitric oxide.

Nitric oxide is vital to life.

As we grow older, we lose the ability to make nitric oxide. As a result, plant-based diets become our primary source of nitric oxide. To replenish, we need nitrate-rich plant-based natural foods and friendly probiotics that help us make nitric oxide.  You can now check for both dietary nitrates and the corresponding nitrate-reducing oral microflora with MyFitStrip, the next generation saliva nitric oxide test strip. 

MyFitStrip

...Within 10-seconds of testing, MyFitStrip will detect whether dietary nitrate from your plant-based foods are being absorbed in your gut and whether the microflora on your tongue have begun the process of transforming nitrate into beneficial nitric oxide.

Your goal is to achieve two "pink test pads" for 

Optimal Diet + Optimal Probiotics  

This will signify that your diet is rich in plant-derived nitrate and your tongue has friendly nitrate-reducing bacteria

Know your nitric oxide.  If your diet is deficient, you may replenish with the DASH, MIND, or Mediterranean Diets that are nitrate-rich with leafy greens and beets.

MyFitStrip

Friendly bacteria living on your tongue is necessary to transform or reduce nitrate to nitrite, a necessary and required step for nitric oxide conversion

MyFitStrip checks whether the nitric oxide promoting bacteria are active 

The natural nitrate-reducing microflora on our tongue are essential for converting dietary nitrates in vegetables such as beetroot, spinach, arugula and other nitrate-rich whole plant-based foods.

Frequently Asked Questions -

Nitric oxide (NO) is a short-lived gas made by nearly every cell in the body.  It effects are widespread and diverse. NO is an important signaling molecule in our brain and a molecule that dilates our blood vessels.  It keeps our blood cells from sticking together, thereby helping the flow of blood throughout our body.   

NO helps oxygen get to the brain and oxygen-deprived muscles during exercise.  Insufficient NO is often associated with chronic diseases such hypertension, diabetes, dementia, and other metabolic and age related diseases.   

Where does nitric oxide come from?

As we grow older, our cells lose the ability to make adequate amounts of NO. Therefore, dietary inorganic nitrates, found in many vegetables, become a critical source.  Nitrates are absorbed in the gut and circulate to the saliva glands where they are released into the mouth.  Upon release, nitrate is converted to nitrite by the friendly nitrate-reducing bacteria living on the back of the tongue.   The nitrite is subsequently swallowed and further reduced in the gut and circulation to nitric oxide to exert its health benefits.

Similar to our gut, our mouths contain a mix of good and bad bacteria.  Having a 'good microflora' on our tongue that converts dietary nitrate to nitrite is critical in restoring vascular health. The presence or absence of nitrate-reducing microflora determines blood pressure levels. Eradication of oral nitrate-reducing bacteria through antiseptic mouthwash, such as chorhexidine, or overuse of antibiotics can result in hypertension. 

Studies have also found that periodic tongue brushing may provoke the growth of these healthy nitrate-reducing bacteria.   Others have found that increased dietary intake of inorganic nitrate shifted the oral microflora to a richer population of nitrate-reducing bacteria with improvements in cardiovascular health
