The MTHFR gene error can lead to a host of deficiencies that ripple through your health, impacting everything from your liver to your mood. A deficiency in the essential amino acid Methionine, for example, can manifest in elevated cholesterol, liver issues, and even dementia. This deficiency is closely linked with low levels of SAM-e, a crucial molecule in the body, and can inhibit the recycling of Glutathione, the body's master antioxidant.

Further complicating the picture are the roles of various B vitamins like B12, B9 (Folate), B6, and B2. An MTHFR gene error can disrupt these vital nutrients, leading to extreme fatigue, mood changes, and a cascade of other symptoms, including anemia and neuropathy. The gene error also affects the production of other important molecules and amino acids like L-Serine, which is critical for central nervous system function and Glutathione production. All told, the MTHFR gene error can have a far-reaching impact on your overall health.
