The Vitamin Deficiency That Looks Like Depression (MTHFR)

Summary

Key Points

• The MTHFR gene produces the MTHFR enzyme, which is crucial for converting folate into methylfolate, a form essential for methylation processes in the body. 0:34
• Folic acid, a synthetic form of folate, is not naturally occurring and requires transformation by a different enzyme (DHFR), which is less efficient in humans compared to mice, potentially leading to issues when consumed. 2:32
• Proper methylation is vital for regulating gene expression, turning genes on and off as needed, and disruptions can lead to various health problems, including mental illness. 2:56
• Low levels of methylfolate and B12 can lead to elevated homocysteine, which impairs the production and balance of key neurotransmitters like dopamine, serotonin, and norepinephrine, and increases anxiety-inducing glutamate. 4:44
• Glutathione, an antioxidant, may need to be supplemented to combat oxidative stress and help lower homocysteine levels when other interventions fail. 6:44
• Supplementing with methylfolate and methylcobalamin (B12) may not be sufficient if oxidative stress is high, as the enzyme at their intersection is sensitive to free radicals. 6:51
• High homocysteine levels are associated with low methylfolate and can be exacerbated by oxidative stress, which can shut down the enzyme responsible for recycling homocysteine. 7:11
• Riboflavin (Vitamin B2) acts as a co-factor for the MTHFR enzyme, meaning low levels of riboflavin can compromise MTHFR enzyme function even without a genetic variant. 8:31
• Individuals can develop 'dirty genes' or a functional MTHFR deficiency through lifestyle and environmental factors, such as consuming high doses of folic acid, nutrient deficiencies, or exposure to medical procedures like laughing gas, even if they don't have a genetic MTHFR variant. 9:04
