Regular question at the pharmacy: Collagen

So, during the last weeks I have gotten a lot of questions about collagen. I do not know if it is the advertising in general or the doctors’ recommendations or a combination of the two, but it has gotten quite interesting. Many advertisements recommend the intake of collagen orally through capsules or powder. Let us have a look at collagen’s chemical structure for a quick moment:




It is a huge protein molecule that would never cross the barriers of the intestine. The only way this molecule could be absorbed is if it injected directly to the blood stream, or else the body’s own molecules will just break it down. So I would never recommend to use collagen in capsules or powder form, it is just a waste of money.
