What is MTHFR and why does it matter?

MTHFR (methylenetetrahydrofolate reductase) is an enzyme that converts folate into its active form, which your body needs for countless critical processes including DNA synthesis, detoxification, and neurotransmitter production. Mutations in the MTHFR gene can reduce enzyme efficiency, leading to reduced folate metabolism and impaired health.

Who should get MTHFR testing?

Anyone interested in optimizing their health can benefit from MTHFR testing. It's especially useful for people with chronic fatigue, anxiety, depression, memory issues, chronic pain, or a family history of these conditions.

How is the test performed?

Order the MTHFR Genotype test from Cell Science Systems online through our Fullscript store, where every order is physician-authorized. Checkout takes a few minutes and needs no appointment. A collection kit ships to you, you collect a simple cheek swab at home following the instructions, and send it back to the lab. The lab processes your sample in about 10 business days, and your results are released to you securely online.

Can I order the test from any state?

The test ships to most of the US. It is not currently available in New York, New Jersey, Rhode Island, Hawaii, or Puerto Rico; checkout confirms availability for your zip code before you pay.

What happens after I get my results?

Once you receive your results, our healthcare professionals can review them with you and recommend a personalized supplementation protocol based on your specific MTHFR status and overall health profile.

Do MTHFR mutations mean I have a disease?

No, MTHFR mutations are genetic variants, not diseases. Approximately 30-40% of people carry at least one mutation. They only matter if you experience symptoms that improve with personalized nutritional support.

Can I take regular folic acid if I have an MTHFR mutation?

High-dose folic acid supplementation may accumulate and cause problems for some people with MTHFR mutations. That's why L-methylfolate, the active form your body can use directly, is often recommended instead.

What is MTHFR?

MTHFR (methylenetetrahydrofolate reductase) is an enzyme that converts dietary folate into its active form, L-methylfolate, which your body uses for critical processes including DNA synthesis, cell repair, detoxification, and neurotransmitter production.

Mutations in the MTHFR gene can reduce the enzyme's efficiency, making it harder for your body to process folate and creating a cascade of downstream effects on energy, mood, immunity, and overall health.

The good news? Once you know your MTHFR status, targeted nutritional interventions can compensate for genetic limitations and restore optimal function.
