The Methylene Blue 90-Day Protocol

Precision longevity is not a guess — it's a closed-loop system. We use epigenetic biological age testing[1] to validate the cellular effects of Methylene Blue Ultra, measured by the Pace of Aging biomarker[2]. This protocol is grounded in peer-reviewed clinical evidence.

THE THREE-STEP LOOP

  1. 01

    BASELINE TEST

    Order your TruDiagnostic TruAge epigenetic age test before starting. This measures your biological age — not your chronological age — using DNA methylation patterns, the most validated biomarker of biological aging.

    Metric: TruAge biological age score
  2. 02

    90-DAY SUPPLEMENT

    Take methylene blue daily following the flat 5-10 mg/day titration schedule, up to a 20 mg/day routine ceiling. Track subjective markers (energy, focus, recovery) in parallel.

    Duration: 90 days continuous
  3. 03

    RETEST & MEASURE

    After 90 days, repeat your TruDiagnostic test (sold separately). Compare your biological age score before and after to track any changes in your biomarker data. This is what biomarker-compatible supplementation looks like.

No published randomized trial has tested chronic daily oral methylene blue in healthy adults for cognitive or mitochondrial endpoints. The 5-10 mg/day range is an extrapolation from single-dose human studies and from chronic dosing in patient populations, not a tested protocol.

What You're Measuring

These biomarkers track the core mechanisms of aging. For enhanced results, consider combining methylene blue with synergistic compounds like NAD+ precursors, CoQ10, or PQQ.

Primary
Epigenetic Age (DNAm)
TruAge biological age via DNA methylation — the gold standard for aging measurement.
Primary
Pace of Aging
DunedinPACE score measuring how fast you are aging right now — year over year rate.
Secondary
Telomere Length
Chromosome end-cap length as an auxiliary aging marker, tracked via TruDiagnostic panel.
Secondary
Immune Cell Composition
Epigenetic deconvolution of immune cell proportions — tracks immunosenescence markers.
Optional
NAD+ Levels
Intracellular NAD+ concentration reflecting mitochondrial metabolic capacity.
Optional
Mitochondrial Function
Markers of electron transport chain efficiency and ATP synthesis rates.

USP-GRADE PURITY

Unlike industrial-grade MB containing heavy metals (arsenic, mercury, lead), Methylene Blue Ultra will be USP-Grade, formulated to exceed USP purity requirements at >99.9% purity.

  • USP grade target: >99.9% purity
  • Precision-dosed capsules, strength confirmed at launch
  • Third-party COA testing planned for every production batch
  • cGMP-standard manufacturing
  • Full heavy metal panel published per batch at launch

Methylene Blue Ultra launches Q3 2026. In the meantime, see our 7-brand comparison.

Frequently Asked Questions

How long is the methylene blue protocol?+

The Methylene Blue Ultra protocol runs for 90 days. You take a baseline epigenetic age test before starting, follow a flat 5-10 mg/day methylene blue titration for 90 continuous days, then retest to quantify changes in your biological age. The total timeline including test processing is approximately 14 weeks.

What does the TruDiagnostic test measure?+

The TruDiagnostic TruAge test measures your epigenetic biological age using DNA methylation patterns — a validated non-invasive biomarker of aging. It also tracks the Pace of Aging (DunedinPACE score), which shows how fast you are aging year over year. Additional markers include telomere length and immune cell composition via epigenetic deconvolution.

How much does the methylene blue protocol cost?+

The planned protocol bundle includes two TruDiagnostic TruAge test kits (baseline and retest) and a 90-day supply of Methylene Blue Ultra capsules. Methylene Blue Ultra has not launched yet, so the bundle is not available for purchase today — join the waitlist for preferred pricing at launch.

What dose of methylene blue is used in the protocol?+

The protocol follows the site's flat oral titration schedule: start at 5 mg/day, hold at least 7 days, then move to the 10 mg/day target — that is the destination, not a step toward something higher. 20 mg/day is a routine ceiling, which is editorial judgment anchored to the servings sold in this category, not a study finding. Oral methylene blue is not dosed by body weight — every human oral study used a flat fixed dose. Methylene Blue Ultra capsules will be USP-grade, with third-party COAs published for each production batch at launch.

What biomarkers does the protocol track?+

Primary biomarkers tracked are Epigenetic Age (DNAm biological age via TruDiagnostic) and Pace of Aging (DunedinPACE score). Secondary biomarkers include telomere length and immune cell composition. Optional markers include NAD+ levels and mitochondrial function markers. The protocol delivers a quantified before-and-after delta rather than subjective assessments.
