What we need to know about "Collagen"

Okay people . . . so we've all heard about "collagen" making us look younger.
And it being called the "SECRET FOUNTAIN OF YOUTH"!
Well today . . . let's dig a little deeper and find out what's true and what's not.
First up . . . what exactly is "collagen"???
Well . . . Collagen is the most abundant protein in the human body and has great tensile strength. It's the main component of cartilage, ligaments, tendons, bone and teeth. And it strengthens blood vessels and plays a critical role in tissue and muscle development.
Simply said . . . it's the substance that holds the body together.
And the body actually produces "all" the collagen it needs "naturally" when we're young.
But . . . as we age . . . collagen production decreases by 1% per year, which contributes to aging, wrinkles and a reduced elasticity and hydration in the skin.
And this 1% loss is called "aging gracefully"
Collagen can even increase the body's hair building proteins, which can result in longer, thicker hair.
And guess what???
This is even one of the reasons some of us gray faster than others.
You see . . . collagen supports the healthy structure of the hair follicle, which is where the "pigment" that gives hair its color is produced.
So why do some of us age or gray faster than others???
