Experience

The Discovery

Together, Juliana and Dr. Green used the saliva strip to guide her dietary choices—focusing on nitrate-rich foods like beets and arugula to optimize her nitric oxide levels. By tracking her progress and fine-tuning her nutrition, Juliana became a National Speedskating Champion in the 1,000m and came within striking distance of breaking the 5-minute mile at UC Berkeley. Inspired by this success, Dr. Green went on to create MyFitStrip, the innovative company behind Berkeley Life and Berkeley Test, and co-inventor of Calroy Health Sciences' Vascanox. Today, these premium formulations can be found through Designs for Health, Fygg, and other leading providers of clinically supported nitric oxide nutraceuticals.

Why MyFitStrip

MyFitStrip is a pioneer in developing prebiotic formulas to enhance nitric oxide and restore a healthy oral microbiome. The beneficial bacteria in your mouth play a critical role in how your body processes prebiotic nitrate—a step that is vital for oral health, vascular blood flow, and immune support. Unfortunately, conventional harsh toothpastes and antiseptic mouthwashes can disrupt these friendly bacteria, inadvertently reducing your natural nitric oxide production. As an elite athlete, Juliana experienced this setback firsthand, completely reshaping how she viewed her oral wellness routine and its direct impact on her athletic performance.

So, they built something better. MyFitStrip introduces a new generation of science-backed oral wellness products—including slow-release lozenges, bioactive chewing gum, and 10-second saliva biomarker strips. Together, they are engineered to support a balanced oral ecosystem that feels enjoyable, easy, and like a ritual you actually look forward to every single day.

Supports a healthier oral microbiome: Prebiotic nitrate exposure shifted the oral microbiome toward increased levels of beneficial nitrate-reducing bacteria.

Helps support nitric oxide production: Nitrate-reducing oral bacteria play an important role in converting dietary nitrate into nitrite, a key step in the body’s natural nitric oxide pathway.

Promotes a balanced oral environment: The study observed reductions in certain bacteria associated with oral inflammation after exposure to a nitrate-based formulation.
