    DNA Repair Enhancement

    Improved genetic maintenance and damage correction.

    TL;DR

    Folate, B12 and niacin are genuinely required for DNA synthesis and repair, and deficiency measurably raises damage markers. NAD+ precursors are biologically plausible but human repair-endpoint data remain thin.

    Why It Matters

    Accumulated DNA damage underlies cancer risk and cellular senescence. Folate deficiency causes uracil misincorporation and chromosome breaks measurable on micronucleus assay.

    How to Measure

    Biomarkers

    Homocysteine
    RBC folate
    Vitamin B12 / MMA
    8-OHdG
    Micronucleus frequency

    Optimization Protocol

    Ensure folate, B12 and niacin sufficiency and keep homocysteine below 9 umol/L. Limit the actual damage sources: alcohol, UV exposure, smoking, and excess visceral fat. Treat NAD+ precursors as optional and experimental at 250-500 mg daily.
