Cysteine is an amino acid, which plays a crucial role in the synthesis of proteins, detoxification, and the production of glutathione, a powerful antioxidant.

Cysteine is an important amino acid that plays a crucial role in the formation of proteins. It is a component of the antioxidant glutathione, which helps protect the body from oxidative stress and damage.

Cysteine is a non-essential amino acid, meaning the body can produce it on its own. However, the recommended amount of methionine is usually expressed as the sum of methionine and cysteine in your diet. Generally, adults should aim to consume about 19 milligrams of methionine plus cysteine per kilogram of body weight per day.

Vegans can obtain cysteine through plant-based sources. Plant-based foods such as legumes, lentils, tofu, tempeh, quinoa, nuts, seeds, and whole grains are excellent sources of protein for vegans. By including a diverse range of protein-rich foods in their diet, vegans can meet their protein and amino acid needs.
