MTHFR testing reveals whether you carry genetic variants that affect methylation—a critical biochemical process for mental health, detoxification, cardiovascular function, and more. This DNA-based test helps identify your capacity to activate folate, make neurotransmitters, and regulate homocysteine.
If you’ve struggled with anxiety, depression, hormonal imbalances, or chronic fatigue, knowing your MTHFR status can unlock personalized treatment strategies to support methylation efficiency and brain chemistry balance.

MTHFR stands for methylenetetrahydrofolate reductase, an enzyme that activates folate into 5-MTHF (methylfolate)—the form your body needs to fuel methylation.
Two common SNPs (genetic variants) are tested:
These variants can result in:
This is a one-time saliva or blood test—once you know your genetics, you can tailor your nutrition and supplementation for life
Methylation is a foundational process for mental health, influencing how the body produces neurotransmitters, detoxifies harmful substances, and regulates homocysteine. When MTHFR function is compromised, these critical pathways can silently become disrupted, contributing to symptoms such as:
While MTHFR testing is not a “magic bullet,” it provides critical insight into how well your body can activate and utilize folate, informing decisions on:
In functional psychiatry, MTHFR testing isn’t about genetic determinism—it’s about understanding your biochemical starting point and crafting interventions that work with, not against, your genetic profile.






Gene | SNP | Result Possibilities |
MTHFR | C677T | Normal / Heterozygous / Homozygous |
MTHFR | A1298C | Normal / Heterozygous / Homozygous |
🧠 These two SNPs affect folate metabolism and methylation efficiency.
