The collagen supplements you consume don’t even make it to your skin as collagen. Here’s why:
As Dr. Mike Nayak flawlessly explains it, collagen is like a whole paragraph. To build it, letters (amino acids) string together to form amino acid chains or words and sentences (peptides). These sentences will make up the paragraph (a.k.a. collagen, or any protein for that matter).
When you ingest collagen protein, your small intestine will use proteases (a type of enzyme) to break it down into peptides because it can’t absorb a whole protein.
After being absorbed through the small intestine, these peptides will further break down into single amino acids, entering your bloodstream and going to the rest of your body, including your skin.
In other words, the “paragraph” you ingested is already broken down into “letters” that in no way resembles the original paragraph once it starts circulating in your body. Therefore, what reaches your skin is not collagen but individual amino acids that do not carry its benefits.
After reaching the skin and other body parts, your body will have to reassemble these amino acids into proteins, but not necessarily collagen. Why? Because the body cannot recognize whether the amino acids came from a collagen supplement or a protein from the food you eat.
The body cannot put the amino acids back into the collagen you ingested. An amino acid is an amino acid; a letter A is just a letter A, no matter where it came from.
The bottom line is: taking collagen supplements is no different than eating protein-rich foods. It’s not true that when you ingest collagen, it will retain its entirety and bring wonders to your skin.
And if that’s the case, consuming a spoonful of those hydrolyzed ground-up animal parts, mixing it with water, and drinking it is not just extremely revolting but also pointless!
You read that right! Collagen powder and other form of collagen supplements are made from pulverized fish guts and bones, jellyfish, and animal bone broth. Blech!
