If you have an MTHFR variant and trouble sleeping, it can be tempting to assume that the answer to "Does MTHFR cause insomnia?" Is a simple "YES." Sadly, like everything else with MTHFR, it's complicated. MTHFR influences folate and one-carbon metabolism (methylation), which in turn affects homocysteine, methionine, S-adenosylmethionine (SAM), neurotransmitter biology and many methylation reactions throughout the body.Sleep itself also changes methylation patterns.

People with the MTHFR gene mutation often face challenges related to methylation, oxidative stress, and sleep quality. Glycine, an amino acid found in both food and supplements, plays a crucial role in addressing these issues. Glycine for MTHFR can act as a methyl balancer, which is crucial for good health.

Obviously, humans need oxygen, that fact isn't lost on us, but often, the factors that get in the way of getting good oxygen are overlooked. A few well-known causes of fatigue, like anemia and iron deficiency, are actually oxygen problems even though we don't really think of them that way, but there are breathing related problems as well. The solution might just be as silly as taping your mouth shut.

Vitamins can improve your sleep, reduce sleep disruptions and protect agains the negative effects of sleep deprivation.
