Conditionally known as a semi-essential or non-essential amino acid, L-Cysteine is a proteinogenic amino acid, called such due to its involvement in the protein construction process within the body.

Conditionally known as a semi-essential or non-essential amino acid, L-Cysteine is a proteinogenic amino acid, called such due to its involvement in the protein construction process within the body.

L-Cysteine can be found in certain foods, most often high protein sources including:

– Chicken
– Eggs
– Diary
– Red Peppers
– Onion
– Broccoli

Important within various roles of the body, L-Cysteine is involved in the synthetising of certain proteins within both animals and plants. In relation to humans it is known for its benefits in the production process of keratin which makes up both hair and nails. With this being the case, L-Cysteine assists the protein keratin to hold its shape as it\u2019s carried around the body.

Involved in the systems of the body which deal with detoxification, this amino acid seems to provide anti-oxidative properties to protect the body from free radical related damage.

N-ACETYL L-CYSTEINE
More commonly known as NAC, N-Acetyl L-Cysteine is L-Cysteine which has been attached to an acetyl group.
In its native form it is a white powder like substance, which is generally recommended to be mixed with water (when sold in its pure form).

Other Possible Benefits
Cysteine has been suggested as a potential antidote for reducing certain effects from excessive alcohol use including liver damage and hangovers. The reason for this is due to Cysteine being involved in the metabolic process which turns acetaldehyde into the innocuous acetic acid, although no benefits are thought to be seen when alcohol consumption is low (Prince H, Parker CM, Smith GG, Gonzales LJ (April 1974). “Protection against acetaldehyde toxicity in the rat by L-cysteine, thiamin and L-2-methylthiazolidine-4-carboxylic acid”).
