Methionine is controlling the level of helpful sulfur containing compounds found in our body. These compounds are vital in our defense against toxic compounds such as the heavy metals in our liver.

It can increase the levels of blood with the homocysteine chemical especially to people with low folate and Vitamin B6 and 12 in their bodies or with people that are having trouble in processing the homocysteine. Too much of it is linked to a higher risk of heart and blood vessel diseases.

Liver diseases such as cirrhosis: The liver disease might be worsened by methionine.

Deficiency of Methylene tetrahydrofolate reductase or MTHFR: This disorder is inherited. This disease changes our body’s way of processing the homocysteine.
