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
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.
Supporting Supplements
Folate (Vitamin B9)
Folate is genuinely required for DNA synthesis and repair, and correcting deficiency reduces measurable chromosome damage.
NMN
NMN raises NAD+ levels in humans, but DNA repair benefits remain unproven outside animal models.
