Cystine is a white solid at room temperature and its source is identical to Cysteine. Cystine is a sulfur containing amino acid which is actually made from the two amino acid molecules of cysteine. This process is done via a reduction of the amino acid molecules.

Like its derivative chemical cysteine, cystine is found in large amounts in animal skeletal tissue, connective tissues and also in the digestive enzymes. Cystine may be used as a supplement and it may also be obtained through high quality food protein sources such as found in animal protein and plant protein.

History and Origin

Cystine is readily available in many animal proteins and plant proteins. Industrial manufacture of cystine on the other hand is done through the reduction of the disulfide link to harvest the corresponding thiol cysteine. Cysteine is further processed yielding cystine.

Ancient Uses

The use of cystine during the ancient times was unheard of but the natural sources of this chemical are used basically for food. Animal meat which is known to be a rich source of high quality protein are used mainly for food and plant protein sources are also used for food and may also be used for their health giving properties.

Modern Uses

Cystine is needed for the utilization of Vitamin B6 which is vital for the body’s many metabolic processes. Cystine may increase wound healing time and may also facilitate tissue healing in burns. Cystine supplements may also help people with increased mucus production as seen in chronic bronchitis and cystic fibrosis. Cystine may also help diabetics as this chemical promotes insulin production by the pancreas. This chemical may also be responsible in the increase of the level of glutathione in the major organs for the body like the lungs, kidneys and liver. Glutathione has an anti aging effect that may influence the body on a cellular level. Cystine may also help people who are addicted to alcohol and cigarettes. It has detoxification properties that can protect the lungs and liver from the damage of smoking and alcohol. Liver damage is prevented as well as reduces the feeling of hangovers after drinking excessive alcohol.

Side Effects

Cystine may have adverse reactions to medicines used to regulate blood sugar. It is therefore necessary to consult your doctor if you want to use this chemical supplement for your condition. Always remember to follow the recommended daily allowance for cystine to prevent serious medical interactions.

Pregnant and breastfeeding women must not take supplements that contain cystine unless recommended by a medical professional. Very young children are also cautioned against taking cystine for their illness; there is not enough research to back the effectiveness of this supplement to treat conditions in very young patients. It is also important to consult your doctor if you want to use this supplement for your condition. Taking supplements for any medical conditions must be under the care of a licensed medical professional to be able to know the right dosage and any adverse reaction with the medication you are currently taking.
