Free tool · For APOE4 carriers

Your labs say normal. Are they optimal for APOE4?

Lab ranges describe the general population. Phoenix uses stricter brain-health targets for carriers. Enter a few numbers from your last blood test and see where you stand.

Private by design: your numbers never leave your browser.

Cholesterol and blood fats
  • Counts the particles that carry cholesterol into artery walls. Many lipid experts read it as a sharper signal than LDL cholesterol.

    Why this ApoB target

  • The cholesterol most labs report. APOE4 carriers tend to run higher LDL, and the 2024 Lancet Commission lists high LDL in midlife as a dementia risk you can change.

  • Fat carried in your blood. High levels often travel with insulin resistance.

    Why this Triglycerides target

Blood sugar
  • Your average blood sugar over about three months. Diabetes is one of the dementia risks you can change, per the 2024 Lancet Commission.

    Why this HbA1c target

  • Your blood sugar after an overnight fast. A one-day snapshot, best read beside HbA1c.

    Why this Fasting glucose target

    in mg/dL

  • Shows how hard your body works to keep blood sugar steady. It often rises years before blood sugar does.

    Why this Fasting insulin target

Inflammation and B vitamins
  • A sensitive marker of low-grade inflammation. A recent cold or injury can push it up, so read a single result with care.

    Why this hs-CRP target

    mg/Lin mg/L

  • Rises when B12, folate or B6 run low. Higher levels are linked to faster brain shrinkage and memory decline in older adults.

    Why this Homocysteine target

    µmol/Lin µmol/L

Nutrients
  • Low levels are common. The range here is the Phoenix target, not a dose target: going above it brings no extra benefit, and the right dose depends on your doctor and your other results.

    Why this Vitamin D target

    in ng/mL

  • The share of omega-3 fats in your red blood cells, a read on your intake over the past few months. Phoenix aims above the level research links to lower heart risk: a Phoenix choice for carriers, not a target proven for the brain.

Your results show next to each marker.

This is education, not medical advice. A result outside a target is a reason to talk with your doctor, not to change a medicine or supplement on your own.

Why no Lp(a)? It is mostly set by your genes, so Phoenix reads it once as a risk level (the National Lipid Association categories), not as a target to work toward.

Upload your blood test PDF. Phoenix reads every marker it supports against APOE4 ranges, tracks your changes over time and helps you choose what to try next, with other carriers beside you.

Common questions

Frequently asked questions.

Do my numbers leave my device?

No. The comparison runs in your browser. When the page opens it loads the ranges Phoenix uses, and after that nothing you type is sent anywhere: not to Phoenix, not to analytics.

If you ask for the free guide, the form sends your email and your APOE4 status. It never sends your lab values.

Where do the targets come from?

They are the same ranges the Phoenix app uses when members upload a blood test: the stricter brain-health targets Phoenix sets for APOE4 carriers. Most rest on research in the general population, read with APOE4 in mind. Few studies set targets for carriers alone.

What does "Room to improve" mean?

Your result is inside the usual lab range but outside the Phoenix APOE4 target. "Out of range" means it is outside the usual lab range itself.

Why is Lp(a) missing?

Lp(a) is mostly set by your genes, so it is measured once and read as a risk level, not a target to work toward. Phoenix uses the National Lipid Association risk categories for it, and the checker leaves it out rather than invent a target.

Where does the omega-3 index target come from?

Research links an omega-3 index of 8% or more to lower heart risk. Phoenix aims for 10-12% for carriers, above that level. That higher aim is a Phoenix choice, not a target proven for the brain. Above 12% is fine: going higher brings no extra benefit.

Is this medical advice?

No. It is education, to help you prepare questions for your doctor. Do not start, stop or change a medicine or supplement based on this page.
