DL-Methionine Introduction:
H&Z® DL-Methionine is one of the physical forms of methionine. 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.

DL-methionine Function:
1. DL-methionine can be used as nutional supplement. DL-methionine has the same effect with L-methionine, but DL-methionine is cheaper.
2. DL-methionine can be formulated as a flavoring agent.
3. 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. DL-methionine has a myocardial protective effect.
5. DL-methionine has an antidepressant effect.
6. DL-methionine has a blood pressure lowering effect.
7. DL-methionine has an antivirus poison eradicates effect.
8.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%.
DL-methionine Application:
1. Food grade:
DL-methionine can be used as nutrition enhancer, flavouring agent, improving food nutrition value and flavor.
2. Feed grade:
DL-methionine can improve animal production, health and quality of animal products.
3. Medicine grade:
DL-methionine can protect liver and myocardial, fight depression, fall blood pressure.
