DEPRESSION: Methylation Station

The best holistic approach to depression considers the mental/emotional as well as the biochemical. Let’s talk for a moment about the biochemical component:

Firstly, there are multiple biochemical components to consider when assessing depression. Specifically, this discussion will focus on the most common biochemical dilemma - the ability to methylate. What exactly is methylation? Methylation is when a ‘methyl group’ gets attached to a molecule in the body. This comes to fruition as DNA production, neurotransmitter production, energy production, histamine metabolism, and mood balancing just to name a few. DNA methylation has been shown to vary between regions of the brain and even possibly between cells in those regions [1].


Depression is a common symptom when the body’s ability to methylate becomes impaired. This occurs when the cells of the body methylate too much or too little. When the body ‘under-methylates’, symptoms may include depression, OCD tendencies, a calm exterior with a ‘tense’ interior, better with a SSRI medication, seasonal allergies, and high libido. The opposite may occur when the body ‘over-methylates’. Symptoms of over-methylation may include depression, high anxiety or panic, sensitivity to certain foods, adverse reaction to SSRI medications, sleep problems, absence of allergies, and low libido.

This is why understanding methylation status is an important component when considering the etiology of depression. A defect in an important gene (the MTHFR gene) can make methylation difficult for many individuals, contributing to a depressed mood. Another common denominator appears to be histamine. In fact, a recent study proposes that histamine might be a missing component when considering depression on a biochemical level [2]. High levels of histamine in the body (as well as low levels) may lead to symptoms of depression.


Through personalized guidance, methylation can be optimized and histamine levels can be brought back into balance. Could methylation or histamine be the reason for putting a damper on your mood? Book an appointment today!
