Cysteine

What is Cysteine?

Cysteine is a non-essential amino acid that contains sulfur, which is important for forming disulfide bonds in proteins. It acts as a precursor to glutathione, a potent antioxidant in the body. Cysteine supports detoxification processes, immune function, and the maintenance of healthy skin, hair, and nails.


Why do I have an intolerance?

Cysteine intolerance may arise from an inability to properly metabolize sulfur-containing compounds. This could result from genetic factors or impaired liver function. When cysteine isn't broken down efficiently, it can cause digestive symptoms such as bloating, abdominal pain, or even sulfur-smelling gas.


What can I do about it?

Managing cysteine intolerance involves limiting foods rich in sulfur, such as eggs, garlic, onions, and certain animal proteins. Adopting a low-sulfur diet can help reduce symptoms. Additionally, ensuring that your liver is functioning optimally through a balanced diet and possibly supplementation can help improve cysteine metabolism.
