MTHFR (Methylene Tetrahydrofolate Reductase) An important enzyme that helps biotransform 5,10 methylene tetrahydrofolate into methylated folate Some people have a variant of the normal gene known as the MTHFR gene (a single nucleotide polymorphism) which impairs proper methylation An MTHFR SNP can contribute to high homocysteine and related diseases MTHFR Variants (or single nucleotide polymorphisms =SNP) There are two relatively common SNPs: A1298C clinically irrelevant will not effect homocysteine levels does not require any specific supplementation C677T can effect homocysteine levels patient may need more folate or 5-methyl-folate Utilizing the methionine pathway by adding methyl donors like trimethyglycine and choline can bypass the problem of MTHFR variants Manifestations of Elevated Homocysteine Sources of Methyl Groups B vitamins folate, B-6, B-12 Trimethylglycine (betaine) Choline Methionine SAMe Metabolically Directed Approach to Elevated Homocysteine Look for root causes of homocysteine elevation chronic inflammation, hypothyroidism, poor diet, MTHFR variants When replacing needed B vitamins, take into account the patients individual metabolic needs For example, a Dysaerobic patient will benefit from folate, but may suffer from increased Dysaerobic imbalance from B-6 and B-12
What we know Vitamin B 12 deficiency is common in individuals over 60 years of age and may contribute to elevated blood homocysteine
Safety Advantage: Life Extension NAC There's still some debate surrounding NAC's long-term safety profile, which we'll discuss later in this guide.3 4 25 As a result, we favored products that make it easy for consumers to start conservatively and adjust their intake over time if needed

Binding the toxin to glutathione allows it to be easily moved out of the cell via several different transmembrane efflux pumps
