Collagen, by definition, is actually a protein already found in your body (science anyone?) More on that soon.
So let's first agree on science.
Now, before you supplement your depleting collagen production (if you're over 25 years old, yes it's unfortunately decreasing), first learn about what collagen is, its important functions, and how your body manufactures it!
What is Collagen? (Protein, anyone?)
Collagen is the most abundant type of protein found in all mammals, including humans.
It is located in many parts of our bodies including hair, nails, skin, bones, muscles, tendons, our blood vessels, many vital organs including the heart, lunges and our digestive system, most notability the small intestine.
Collagen's important functions
One of the critical functions of collagen is to simply makeup our skeleton — bones are made of collagen calcium and phosphorus. Collagen also holds our skin in place and allows muscles to be attached to bones and other muscles (tendons and ligaments are made of collagen).
If you had to guess, what do you think your teeth and eyeballs are made of? Yup, collagen. Want a crazy statistic?
Collagen makes up nearly 1/3 of your body's protein composition.
Many like to call it the "glue" that holds it all together. And actually, for you language and history nerds, collagen comes from the Greek word “kólla”, which literally means glue.
Our body's manufacturing of Collagen (insert sad face here)
Even as a day old new baby, your body was already manufacturing collagen.
But, then the wheels start to fall off.
Our bodies are really, really good at making collagen itself, until about 25-30 years of age.
This decrease in collagen materializes as wrinkles, aches in our joints, skin issues, digestive problems (that we blame on many different things, but never make the collagen connection), loss of hair, heart problems, and more.
So, collagen is super critical to our bodies but our bodies manufacturing of it decreases as we age.
