Chronic alcohol ingestion is related with leaky gut syndrome. Colostrum is well-studied that it has a effect of decreasing the degree of leaky gut syndrome.

So the investigators are planning to find out whether Colostrum has a effect of decreasing the degree of leaky gut syndrome.

We randomly sort the participant as placebo group and colostrum group. Each group consists of 17 people. and the duration of our study for one participant is 3 weeks. (Participant takes colostrum for 3 weeks.)

When a person gets leaky gut syndrome, his or her endotoxin and lactulose/mannitol ratio (L/M ratio, in urine) can elevate.

So We will compare the value of those two parameters and LFT. etc. after the administration of colostrum or placebo.
