Bloodwork · When-X · 8 playbooks
What to discuss when the number is off
Each playbook starts from a pattern in your blood test and names the markers. It points to compounds worth asking about. Then it sends the blood draw to a doctor or to our bloodwork partners. None of them is a plan you should follow without that talk.
Read this first
- Coach, not doctor. Aaron Cuha is a coach, not a doctor. No medical credential is claimed for him, or for these pages. A number on a blood test is something to talk over with a doctor, not something to diagnose yourself with. Nothing here is a prescription, a plan to follow, or a reason to start or stop a medicine. Educational use only. This database summarizes published research and is not medical advice. Where a dose appears it is a record of what a trial or clinic ran, or what people describe doing, with its source attached. Nothing here is a recommendation for personal use.
- Knowledge stays free. Knowledge stays free. Every page, every guide and every tool is free to read and stays free. No partner paid for a place on these pages.
- Three kinds of lab page, kept apart. /bloodwork is blood tests for people. /testing and /prices/labs are lab tests on peptide vials. /supplements/quality is what is in the bottle.
- Low
When the omega-3 index is low
A low omega-3 index usually means oily fish and EPA/DHA have not been part of the week. It is a food-and-capsule status number, not a heart-attack diagnosis.
Open - Low
When 25-OH D is low
A low 25-hydroxy vitamin D means you are in the group the huge prevention trials mostly did not enroll. Repletion is a real clinical conversation. It is not proof that a bottle will prevent cancer or death.
Open - Low
When RBC magnesium is low, or symptoms plus a useless serum
Serum magnesium can look fine while tissue is not. The owner's rule is to read RBC magnesium. Cramps, poor sleep, or a GLP-1 / low-carb week do not replace the lab.
Open - High
When ferritin is high
High ferritin is the most important negative on this site. The owner publishes his own at 435 and takes no iron, including inside a multi. Do not supplement iron because a bottle said 'men's health'.
Open - High
When HbA1c or fasting glucose is high
A high A1c or fasting glucose is metabolic medicine. Food, training, sleep, and prescribed therapy come first. Berberine is the owner's marker-tied option, not a metformin replacement you start from a podcast.
Open - High
When ApoB is high, or LDL looks fine and pattern B is not
ApoB counts particles. LDL-C counts cargo. The owner's bergamot rule is written for small-dense LDL / pattern B. Psyllium can nudge LDL a little as an adjunct to diet. Neither is a statin.
Open - High
When hs-CRP stays high
A stable high hs-CRP is an inflammation conversation. JUPITER used 2 mg/L and above as an entry criterion for a statin trial. The owner's curcumin rule uses the same marker for a very different bottle.
Open - High
When homocysteine is high
Homocysteine is the marker the owner's methylated-B rule waits on. B vitamins can lower it. HOPE-2 and NORVIT then showed that lowering it did not deliver the vascular-event benefit people wanted.
