Homocysteine is a non-protein amino acid, synthesized from methionine and either recycled back into methionine or converted into cysteine with the aid of the B-group vitamins [citation needed]. About 50% of homocysteine [ citation needed ] is converted back to methionine by remethylation via the methionine synthase major pathway.
Total plasma homocysteine. Homocysteine levels typically are higher in men than women, and increase with age. [15] [16] Common levels in Western populations are 10 to 12 μmol/L, and levels of 20 μmol/L are found in populations with low B-vitamin intakes or in the elderly (e.g., Rotterdam, Framingham).

Methylenetetrahydrofolate reductase deficiency is the most common genetic cause of elevated serum levels of homocysteine (hyperhomocysteinemia). It is caused by genetic defects in MTHFR, which is an important enzyme in the methyl cycle. [1] Common variants of MTHFR deficiency are asymptomatic and have only minor effects on disease risk. [2]
There are not enough studies on whether pills are as effective in improving or eliminating symptoms as parenteral treatment. [12] Folate supplementation may affect the course and treatment of pernicious anemia if vitamin B 12 not replaced. [65] In some severe cases of anemia, a blood transfusion may be needed to resolve haematological effects. [5]

Long-term effects are unknown. SAM is a weak DNA-alkylating agent. [25] Another reported side effect of SAM is insomnia; therefore, the supplement is often taken in the morning. Other reports of mild side effects include lack of appetite, constipation, nausea, dry mouth, sweating, and anxiety/nervousness, but in placebo-controlled studies ...
