Is homocysteine on the low side harmful?

Low homocysteine is generally harmless.

Homocysteine is an intermediate product of methionine and cysteine metabolism. Under normal circumstances, homocysteine values are 5-15μmol/L. Low homocysteine generally refers to homocysteine values below 5μmol/L. In theory, the lower the homocysteine value, the better. Therefore, low homocysteine generally has no harm.

If homocysteine is low and obvious discomfort symptoms occur, it is necessary to see a doctor in time for systematic examination. After a clear diagnosis, treatment is standardized according to the cause.
