The £89 DNA Methylation Test That Could Explain Your Anxiety And low mood

If you've been struggling with low mood, anxiety, fatigue or brain fog and haven't found clear answers, there's a good chance nobody has looked at your methylation pathway. It's one of the most clinically significant areas in personalised nutrition — and one of the most overlooked in conventional medicine.

A genetic methylation test changes that. Here's what it involves, what it reveals and who it's most useful for.

What is methylation testing?

A genetic methylation test analyses your DNA for specific variants — known as SNPs, or single nucleotide polymorphisms — in the genes that regulate your methylation pathway. These tiny genetic differences influence how efficiently your body processes key nutrients, manages stress hormones, regulates mood and clears toxins.

Unlike standard blood tests, which show you what's happening right now, genetic testing shows you the underlying blueprint — the structural reasons why your body works the way it does. It doesn't change. You test once and the information is yours for life.

What does the test actually look at?

The methylation pathway isn't one single process — it's a network of interconnected cycles, each dependent on the others. A comprehensive genetic methylation test examines variants across all of them:

The folate cycle — how your body converts folate from food into its active form, which the entire methylation process depends on. Key genes include MTHFR, DHFR, MTHFD1 and SHMT1.

The methionine cycle — how your body produces SAMe, the primary methyl donor involved in neurotransmitter production, DNA repair and detoxification. Key genes include AHCY, MTR, MTRR, BHMT and TCN2.

The neurotransmitter cycle — how your body produces and breaks down serotonin, dopamine and adrenaline. Key genes include COMT, MAOA, MAOB and PNMT. This is where the mental health picture becomes particularly clear.

The transsulphuration cycle — how your body produces glutathione, its primary antioxidant and detoxification molecule. Key genes include CBS, CTH and GSS.

The urea cycle — how your body manages nitrogen and oxidative stress. Key genes include NOS and SOD.

Together, these cycles regulate how your body processes stress, mood, hormones, inflammation and environmental toxins. Variants in any of them can create downstream effects that show up as symptoms — often symptoms that have never been properly explained.

Who is methylation testing most useful for?

An imbalance in methylation — whether undermethylation or overmethylation — increases susceptibility to a wide range of conditions. The test is particularly relevant for anyone dealing with:

Psychiatric and mood disorders including depression, anxiety, bipolar disorder and autism spectrum conditions. Chronic fatigue that hasn't responded to other interventions. Poor detoxification — particularly relevant for those on hormone therapy, those with significant alcohol consumption or toxin exposure. Cardiovascular issues including hypertension and circulatory problems. Immune and autoimmune conditions. Fertility challenges. And anyone simply interested in understanding their biology more precisely and extending their healthspan.

What the test reveals

The results identify which SNPs are clinically significant for you — not just a list of variants, but a fully referenced report with descriptions of each gene's function, the effect of your specific variants, and colour-coded genotype information that makes the results readable rather than overwhelming.

You'll get insights into which nutrients your body has a higher demand for — whether that's B6, folate, B12, zinc, magnesium, betaine or choline — and which factors are likely to be inhibiting your pathway, including environmental chemicals, moulds, medications, hormones and heavy metals.

The cost — and why it matters

This is where it's worth being direct. Comprehensive methylation reports from specialist providers typically cost several hundred pounds — often £300–£500 or more when you include the interpretation session separately.

Our genetic methylation test is £89. It covers all five cycles, all clinically significant SNPs, and a fully referenced personalised report. Processed in an ISO certified UK laboratory, with all samples destroyed after six months and genotyping data completely destroyed by six months. Your data is never shared with or sold to third parties. Everything is processed in the UK.

The interpretation session — where we go through your results alongside your symptoms, health history and lifestyle — is where the real value lies. Raw data without clinical context tells you very little. With it, the picture becomes precise and actionable.

What happens after testing

Your results on their own are a starting point. The clinically significant variants only become meaningful when they're read alongside everything else we know about you — your symptoms, your diet, your stress history, your previous test results.

That's what the interpretation session is for. One of our BSc and MSc qualified Functional Medicine Nutritionists will map your genetic variants against your full health picture, identify where your pathway is under strain and build a plan around what your body specifically needs.

Not a generic supplement protocol. A precise, personalised response to what your DNA actually shows.

The genetic methylation test is available for £89. Order yours here or get in touch if you have questions before ordering.
