Your brain is the most important organ to track

Cognitive aging starts decades before symptoms

Homocysteine, omega-3 index, vitamin D, B12, and HbA1c are the five markers most predictive of cognitive aging trajectory. All five are included in the Intelligence and Protocol kits. None are included in a standard annual physical.

Test quarterly. Watch your biology respond.

90 days is enough time for lifestyle and supplement changes to show measurable shifts in your markers. Quarterly testing turns your dashboard into a longitudinal health record — not just a snapshot.

Common questions

Your samples are processed by CLIA-certified partner laboratories that meet all federal requirements for clinical laboratory testing. Cellnexa does not process samples directly — we partner with accredited labs that specialize in direct-to-consumer testing.
The kit includes a safety lancet device that automatically retracts after use. Most people describe it as feeling like a brief pinch. You collect a few drops of blood onto the collection card, let it dry, and mail it back in the prepaid biohazard envelope provided.
After your sample arrives at the lab — typically 1 to 2 business days after mailing — processing takes 3 to 5 business days. Results appear automatically in your Cellnexa dashboard with email notification.
No. Cellnexa provides educational health information to help you understand your biology — it is not a substitute for clinical care. We always recommend discussing results with a qualified physician, particularly if any markers are outside optimal ranges.
Yes. Your data is encrypted in transit and at rest. We never sell personal health data. You can request deletion of all your data at any time from your account settings.
Your dashboard will flag any markers outside clinical reference ranges and recommend follow-up. For markers significantly outside range we recommend consulting a physician. Our physician network can also review your results — see the Physician Review option.
Many HSA and FSA plans cover diagnostic testing. Check with your plan administrator. We can provide an itemized receipt for reimbursement purposes.
We offer a mobile phlebotomy option through our Getlabs partnership — a certified phlebotomist comes to your home for a standard venous blood draw. Available in most major metro areas. Contact us at hello@cellnexa.health for availability and pricing.
