2. Description of the Related Art In recent years, with the westernization of dietary habits, the intake of fat, particularly animal fat, and the accompanying increase in cholesterol intake have been remarkable. In addition, the burden on the liver, which controls metabolism, is increasing due to the imbalance in nutrition and alcohol intake. The liver has circulatory, excretory, metabolic, protective / detoxifying, and hematological functions.If any of these functions is impaired, fatigue, malaise, anorexia, jaundice, and mild fever And various symptoms specific to liver dysfunction will appear.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
Lactoperoxidase and lactoferrin used in the present invention are derived from milk of mammals such as cow's milk, human milk, goat's milk and sheep's milk. Lactoperoxidase and lactoferrin contain a large amount of basic amino acids such as lysine and arginine, and are sometimes collectively called basic proteins. This basic protein can be obtained by purifying milk raw materials such as skim milk and whey using a cation exchange resin. After separating and purifying lactoperoxidase and lactoferrin, respectively, from milk, each can be blended according to the required amount.In particular, it contains lactoperoxidase and lactoferrin obtained using skim milk or whey of milk as a raw material. It is preferable to use a basic protein fraction from the viewpoint of economy and the like.
