Enzyme Myths, Part 1

I see a lot of ads for enzymes on the Internet, many of them making absurd claims or just downright lying. But some of the "major" enzyme sellers have dubious information on their sites. I came across an interesting one that stated: "When taken between meals, it (the enzyme) will be stored in the liver and called upon as needed". Now that's interesting. Enzymes are proteins, and any protein, even an enzyme, will eventually be broken down by the body's own set of protease enzymes. No protein taken orally will survive intact for long (though plant enzymes are more resistant), even those that do get absorbed into the circulation. Our bodies would much rather use ingested proteins as raw materials to build its own proteins, when and where they are needed. Another question: How would one know that the ingested enzyme is being stored? And why in the liver? And how would the liver know when we "needed" the enzyme? The liver is an organ of detoxification and produces many of its own enzymes to metabolize drugs and remove toxins (which is why I don't eat livers, yuck!). It does not store anything. But yet I keep seeing that statement on this company's website, and it annoys me. They should know better. It could be that they subscribe to the unproven and debunked theory of enzyme conservation and mutation, whereby it is thought that a deficiency of enzymes in one part of the body can result in the recruitment of other enzymes in the body to compensate. But that is another myth to be scorned upon at a later date. Bottom line: Enzymes taken orally do NOT get stored anywhere in the body. The vast bulk of the enzyme will remain in the gut, loyally accompanying and breaking down the food it was eaten with until it is inactivated or pooped out. And this is a good thing, we would not want the enzymes we eat, which are in active form, to be stored as they are foreign to the cells of our organs . In other words, the organs would not know what to do with the enzymes except tear them up or activate the immune system and remove them which is what eventually happens to any ingested enzyme/protein absorbed into the circulation. More debunking to come...
