Product Description

 

Product Description

Introduction:L-cysteine is an amino acid antidote, which participates in the reduction process of cells and phospholipid metabolism in the liver, protects liver cells from damage, promotes liver function recovery and vigorous pharmacological effects. It is mainly used for radiopharmaceutical poisoning, heavy metal poisoning, antimony poisoning, hepatitis, toxic hepatitis, serum sickness, etc., and can prevent liver necrosis. If this product is used for the rescue of antimony poisoning, it should be administered in time and in sufficient quantities, so that it can be excreted with antimony ions to the greatest extent possible to generate non-toxic soluble complexes.

Function:
1.Amino acids are of great help to the human body.
First of all, amino acids can help us regulate our own immunity.
Some amino acids can also help us effectively achieve brain health.

2. Fitness, supplemented with sufficient branched chain amino acids, can strengthen muscle synthesis ability, improve recovery ability, and reduce part of fat.

In addition, because branched-chain amino acids make up almost one-third of protein, enough intake of branched-chain amino acids can help reduce muscle loss

3.3. Some amino acids can also help us achieve the purpose of anti-fatigue. Improve physical fitness and vitality.

Application:
Mainly used in medicine, cosmetics, biochemical research and other aspects.

1. Used in bread to promote gluten formation and promote fermentation, mold production, prevent aging, etc.

2. Used in natural fruit juice to prevent vitamin C oxidation and prevent the juice from turning brown.

3. The product has detoxification effect and can be used for acrylonitrile poisoning and aromatic acidosis. The product also has the effect of preventing radiation damage to the human body, and is also a drug for the treatment of bronchitis, especially as a phlegm reducing drug (mostly used in the form of acetyl L-cysteine methyl esterate.

4. Cosmetics are mainly used for beauty water, perm liquid, skin cream for sun protection, etc
