The gold standard
MLux phase time is the most accurate measure of your body clock.
- Melanopic Lux phase time (MLux) is the moment melatonin begins rising in the evening — the most reliable circadian biomarker in clinical research.
- Traditional MLux phase time requires hourly saliva samples under dim light over 6-8 hours. Clinically impractical at scale.
- DIOS derives a MLux phase time passively — from sleep architecture, autonomic data, and smartphone sensors. No saliva sample required.
- Every personalised output in DIOS — medication windows, supplement timing, zeitgeber cues — is driven by MLux phase time.
The DIOS method
Clinical grade first — three layers, one body clock reading.
The calculation
How MLux phase time is calculated.
- 1.Sleep onset anchor: MLux phase time typically occurs 2 hours before sleep onset.
- 2.REM latency correction: Delayed REM beyond 85 minutes shifts MLux phase time estimate later by 0.25 minutes per minute of delay.
- 3.ANS correction: Low parasympathetic activity at sleep onset indicates melatonin has not fully risen.
- 4.AHI modifier: Apnea events above AHI 15 reduce confidence score — sympathetic activation suppresses the PNS signal.
- 5.Rolling average: Each additional night narrows the confidence band.
Confidence builds nightly
More nights. More precision.
The VDR connection
Vitamin D is not just for bones.
- VDR response elements are present on CLOCK and BMAL1 genes — the master regulators of circadian rhythm.
- Low D3 below 150 nmol/L dampens circadian amplitude, fragments sleep, and reduces medication efficacy.
- The Gominak protocol targets D3 at 150-200 nmol/L. The Coimbra protocol uses supervised high-dose D3 at 200-400 nmol/L for autoimmune conditions.
The medication evidence
Eight medications. Published timing evidence.
