China H&Z® Quality DL-Methionine is one of the physical forms of methionine. Quality DL-Methionine is not the natural form of methionine.Methionine is one of essential amino acids constituting the human body, involved in protein synthesis. Because it can not be generated in the body itself, it must be obtained from outside.

Quality DL-Methionine Function:
1. Quality DL-Methionine can be used as nutional supplement. Quality DL-Methionine has the same effect with L-methionine, but Quality DL-Methionine is cheaper.
2. Quality DL-Methionine can be formulated as a flavoring agent.
3. Quality DL-Methionine has a protective role of the liver. Methionine has effects of anti cirrhosis, fatty liver, and a variety of acute, chronic, viral, jaundice liver.
4. Quality DL-Methionine has a myocardial protective effect.
5. Quality DL-Methionine has an antidepressant effect.
6. Quality DL-Methionine has a blood pressure lowering effect.
7. Quality DL-Methionine has an antivirus poison eradicates effect.
8.Quality DL-Methionine is the feed nutrition enhancer.Livestock and poultry lack of methionine, can lead to stunted growth, weight loss, liver and kidney function abate, muscle atrophy, fur, metamorphism and so on.Add 1 kg methionine, feed of 50 kg fish meal nutrition value.Feed in the general content of 0, 05 % to 0.2%.
Quality DL-Methionine Application:
1. Food grade:
Quality DL-Methionine can be used as nutrition enhancer, flavouring agent, improving food nutrition value and flavor.
2. Feed grade:
Quality DL-Methionine can improve animal production, health and quality of animal products.
3. Medicine grade:
Quality DL-Methionine can protect liver and myocardial, fight depression, fall blood pressure.
