MyBody-X angle on MTHFR Kinder

MyBody-X angle on MTHFR in children: MTHFR variants (e.g., rs1801133, rs1801131) are common and affect folate metabolism. They are often marketed as linked to developmental issues, ADHD, or autism, but the evidence is mostly mechanistic or observational, not causal. A DNA test alone cannot diagnose or guide treatment. In children with symptoms, blood biomarkers (homocysteine, folate, vitamin B12) are more clinically useful. Supplementation with active folate (5-MTHF) is only indicated if deficiency or elevated homocysteine is confirmed. Many consumer tests overstate the significance. MyBody-X advises: interpret results with a healthcare professional familiar with the child. Avoid self-prescribing high-dose supplements without lab confirmation.
