You probably came for MTHFR. Most people do. But your C677T or A1298C result doesn’t mean much on its own. How your folate cycle runs depends on the genes that feed MTHFR and the genes that depend on it.
So this MTHFR test reads both common MTHFR variants alongside 17 other methylation genes, across all five methylation cycles. You see the whole system, not one data point, and so does anyone (or any AI) you share your results with.

Each cycle gets its own report, showing your result for every gene and what it’s linked to.
Turns folate from food into the active form your cells use.
Recycles homocysteine back into methionine, with B12 and folate.
The other route out for homocysteine, towards glutathione.
Links methylation to the enzymes that handle neurotransmitters.
Connects methylation to nitric oxide and antioxidant enzymes.
Most people take their MTHFR result to ChatGPT and ask what to do. Your Stride protocol does that for you, using all 18 genes: it reads your results, connects the ones that relate, and ranks what to focus on first. Every action links back to the gene behind it. Then your specialist goes through it with you in your 1:1 consultation.

Everything about the MTHFR & Methylation Test in one place.
This test reads 18 methylation genes, including both MTHFR variants, and gives you 5 reports. The StrideDNA Optimal Health Test reads 110 genes and gives you 45 reports, adding nutrition, fitness, sleep and skin. Both tests include your reports in MyStride, an AI-powered protocol and a 1:1 consultation.
Yes. Upgrade in MyStride for £97.50 and your extra reports use the same sample, so there is no new swab and no new wait.
No. It reads gene variants linked to how your body uses folate and B vitamins. It doesn’t diagnose or predict any condition. If you have symptoms, speak to your GP.
MTHFR variants are common. One or two copies change how efficiently one enzyme works; they aren’t a diagnosis. Your report shows the result alongside your other 17 genes, and your specialist talks it through with you.
Your report and consultation cover which forms of folate and B vitamins suit your results. Check with your GP or pharmacist before starting any supplement, especially if you take medication.
You don’t need to provide another sample! Our Stride Link service allows you to upload your existing 23andMe raw DNA data and receive personalised Stride DNA reports without another test. You can find out more and get started here.
About 10 working days after the lab receives your swab. Your data is encrypted, pseudonymised and stored in the EEA. It’s never sold, and we delete it on request.
