Causes of High Homocysteine Levels (Hyperhomocysteinemia) Many factors contribute to high homocysteine levels: Insufficient folate, vitamin B 6 , vitamin B 12 , betaine, vitamin B 2 , and magnesium Certain prescription drugs (including cholestyramine, colestipol, fenofibrate, levodopa, metformin, methotrexate, high-dose niacin, nitrous oxide, pemetrexed, phenytoin, sulfasalazine) High-methionine diet (including red meat and dairy products) Smoking High coffee consumption Alcohol consumption Advancing age Obesity Genetic variant that causes an impaired ability to metabolize active folate from folic acid Note: Life Extension believes that the optimal range for homocysteine levels is 11 mol/L) has been associated with a substantial increase in risk of dementia in the elderly

Deficiency in vitamin B6 is commonly linked to malnutrition, alcoholism, malabsorption syndromes, or as an adverse effect of certain medications, such as cyclosporine, hydralazine, cycloserine, penicillamine, isoniazid, levodopa, phenelzine and chemotherapy treatments ( Pyridoxine is crucial for the biochemistry of the nervous system, playing a significant role in amino acid biosynthesis and degradation (57, 58)
