For high homocysteine, a common medication is folic acid, which can be taken once a day at 0.4 mg to counteract elevated homocysteine. Another approach includes precision dosing with genetic testing, which is not yet widely available. Homocysteine is generally less than 6 μmol/L, which is the optimal healthy value, greater than 10 μmol/L is a mild risk value, and if it is greater than 15 μmol/L, it should be taken highly seriously. This is because homocysteine affects the level of atherosclerosis and long-term elevation can lead to cardiovascular diseases, such as coronary heart disease, angina pectoris, and even heart and brain infarction. While taking it, folic acid is often combined with vitamin B6 as well as vitamin B12, which can lower homocysteine levels. In addition, high homocysteine should be accompanied by good control of blood pressure, which should be below 140/90 mmHg, as well as regular review of blood lipids and blood glucose.
