🧬 SNP spotlight: MTHFD1 - the gene that powers methylation and DNA repair
Meet the multitasking enzyme that keeps your cells healthy.
MTHFD1 converts folate into the active forms needed for:
✨ Methylation
✨ DNA synthesis
✨ Energy + redox balance
But when SNPs like rs2236225 (R653Q) slow this process, the effects ripple across the body, from fatigue and fertility issues to elevated homocysteine and anaemia.
🚨 Functional red flags:
🔺Poor tolerance to folic acid
🔺Recurrent miscarriage or NTD history
🔺Unexplained fatigue or high homocysteine
🔺Placental or methylation-related complications
💡 Support the cycle:
5-MTHF, folinic acid, B12, P5P, choline, betaine, antioxidants + NADPH support.
When MTHFD1 functions properly, everything else flows more smoothly: your methylation, your mood, and your mitochondria.
