What do you know about your
Your biological age is how old you are physically, rather than just chronologically, and it’s what’s most correlated with age-related disease and longevity

The lab tests and bio-age algorithms we offer hold up to close scrutiny
In a field that is fast-changing, we care deeply about offering the most reliable laboratory tests currently available. That means that the results are reproducible, highly accurate and have been well-validated in scientific studies. They are based on DNA methylation, the most studied epigenetic imprint for age-related assessment.
The bio-age laboratory results you’ll receive are:
- Your current pace-of-aging (your aging “speedometer”) using the DunedinPACE test
- Your telomere length
In addition to laboratory testing, we’ll also review your subjective biological age as calculated through our online health habits questionnaire.
Changing your bio-age is possible with diet and lifestyle tweaks
Dr. Fitzgerald is at the forefront of biological aging research, having conducted the first-of-its-kind clinical trial that demonstrated diet and lifestyle can reverse aging.
In her ongoing work, she and her team incorporate that knowledge with the broader advancements being made in the field of biological age reversal. Their goal is to help individuals reduce and optimize their biological age using primarily straightforward dietary, supplements, and lifestyle adjustments.
Tap into this knowledge and you too can start to get younger.
A consult with our clinical team to review your results and learn what you can start to change is included in your package purchase.
