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]
Zinc and vitamin D are also essential for bone health but have the added benefit for men over 50 by reducing the risk of erectile dysfunction, a condition commonly affecting men over age 40 ...
Tweaking your diet is one of the main ways you can lower disease-causing cholesterol, especially your LDL, explains Ira Monka, D.O., an osteopathic physician specializing in family medicine and ...
Increased intake of these vitamins can lower homocysteine levels and reduce the risk of these conditions. [173] According to the National Health and Nutrition Examination Survey , about 6% of elderly Americans over 70 are severely deficient in vitamin B12, and more than 20% of those over 60 are mildly deficient.
The roaring growth of the over $4 trillion wellness industry over the last decade has been largely fueled by women consumers. But within that larger wellness framework, the competitive ...
Hypertension: which affects up to 50 million people in the United States alone is the major treatable risk factor associated with silent strokes. [29] Homocysteine: elevated levels of total homocysteine (tHcy) an amino acid are an independent risk factor for silent stroke, even in healthy middle-aged adults. [30] [31] [32]
