Homocysteine provides no health benefits. The higher the level of homocysteine, the greater the risk of cardiovascular disease. Conversely, the lower the level of homocysteine, the better. There is no threshold below which homocysteine becomes okay. You want your homocysteine levels to be as low as possible. Many labs & medical literature reported certain normal range of but don’t get pacified by lab reports or your physician. However, you should keep your homocysteine level below 9 micromols per liter of blood if you have no sign of cardiovascular disease and below 7 if you already have evidence of cardiovascular disease or have other risk factors of heart disease.
