diagnostic labs + personalized protocols
to help address root cause symptoms
Choose from over 200+ functional labs
Get access to functional lab testing that goes beyond what your doctor ordered like comprehensive hormone, thyroid and GI mapping tests- revealing what standard labs miss, because we're not looking for disease. We're looking for the root cause of why your body stopped working for you.
There is a version of your life on the other side of understanding your hormones and body as a whole.
Understand your results
Understanding your lab markers shouldn't be gate kept knowledge. We translate your data into plain language and actionable insights- what they mean, where the imbalances are, and what your body is trying to tell you about your hormones, thyroid, gut, or nutrient status.
You can review your results on your own, or schedule a lab review session with one of our functional practitioners to walk through them together. Either way, you're not left staring at a PDF wondering what it all means, and get the clarity you deserve.
Get a personalized protocol
Once you understand what's driving your symptoms, our team of functional practitioners helps build a protocol designed to address them.
Work with one of our experts for targeted nutrition and supplement recommendations as well as lifestyle interventions that fit how you actually live, all based on your labs and your life.

Your health is complex, and your symptoms are only part of the story. We listen, uncover the why, and help you address the root cause.
A more complete understanding of your health
Our connected, root-cause approach looks at how your body’s systems work together to support optimal health.
Low energy, weight gain, brain fog
Often linked to thyroid, metabolic, or hormonal imbalances that routine labs miss
We run deeper testing and connect patterns across your whole system to address the root cause
Bloating, skin flares, digestive issues
Frequently driven by gut inflammation, food sensitivities, or microbiome imbalance
We uncover hidden stressors and triggers and heal the gut to relieve and eliminate symptoms
Hormone issues, poor sleep, chronic stress
Often dismissed or treated in isolation instead of as part of a connected system
We assess hormones, stress, and lifestyle together to restore balance over time
Meet Zeinab Kristen, FDN-P
& Founder of Cync Health
Zeinab is a Functional Diagnostic Nutrition Practitioner and the founder of Cync Health.
After caring for her mother for over a decade while watching her symptoms repeatedly dismissed by modern health systems, one thing became painfully clear: there is a massive gap in women’s health knowledge, and far too often women are consistently gaslit by a system that doesn't believe their lived experience.
With 80% of women experiencing symptoms that can lead to chronic conditions if left unaddressed, and few meaningful solutions offered by conventional care, she decided to take matters into her own hands, and became a certified Functional Diagnostic Nutrition Practitioner with a mission to ensure other women don’t endure the same suffering her mother did.
She founded Cync Health, a functional health practice dedicated to helping women understand their bodies, advocate for themselves, and take control of their health- getting back the lives they are entitled to have, because every woman deserves that much.
