The level of homocysteine in the blood can be measured with a simple blood test that is often, but not always, done after fasting. Homocysteine levels of 12 mmol/L are considered normal and levels below 10 mmol/L are considered desirable.
Fortunately, homocysteine can also be converted into cysteine by the B vitamins, folate, B12 and B6. When an individual consumes large amounts of foods rich in these B vitamins, not only will homocysteine levels go down, but hydrogen sulfide levels can go up since the body uses cysteine to make hydrogen sulfide.he B vitamins folate, B6, and B12 are necessary cofactors in an essential cellular process called the methylation cycle. In this cycle, all three B vitamins are used to convert a potentially damaging molecule called homocysteine into the useful amino acid cysteine.
