How to read this

Phoenix research is longitudinal and observational: we follow real APOE4 carriers over time and compare each member with their own earlier self, with no placebo group, no randomisation, and members choosing their own interventions.

That means these are strong signals pointing at what to test next, not proof of cause. Most nutrition, supplement and lifestyle research you read online has exactly the same design. The difference is that we say so, and we show you the confounders.

HbA1c

Laboratory haemoglobin A1c result · Aim: lower

Magnesium threonate

✓Repeated positive

The same two magnesium-threonate cases nudged HbA1c lower, but Issue 01 does not publish their before-and-after values.

Selected member cases

  1. Magnesium Match · APOE4/4 · female · age 50-59

    HbA1c moved lower in the same clean window; public before-and-after values were not printed.

    What else changed: no nearby starts were recorded.

    Next study: repeat HbA1c after a dated Magnesium threonate window.

  2. Magnesium Mover · APOE4/4 · male · age 50-59

    HbA1c moved lower in the same clean window; public before-and-after values were not printed.

    What else changed: nearby starts included B-vitamin intake not captured.

    Next study: repeat HbA1c after a dated Magnesium threonate window.

Magnesium and homocysteine is 7 members from an answer.

Forty carriers with a dated start and a repeat blood test close it. Creatine, vitamin D3 and B12 sit further back. Your next blood test is somebody else's answer, and theirs is yours.
