Methylation is the process by which nutrients are broken down into usable particles that are then taken into the cells of the body for nutrition. Methylation can be impaired by toxins, sickness, and/or nutritional deficiencies. These problems with methylation contribute to depression, anxiety, bipolar disorder, and other mood disorders as well as fatigue and sleep disturbances. MTHFR is a gene that greatly affects methylation when it is not working well, and many people are affected by this when the gene is not fully functioning. Simple testing can determine your methylation status and how you are breaking down your nutrients. If you struggle with a mood disorder, looking at methylation disorders could help!
