We hear about collagen everywhere, this discreet superhero of your body : in beauty supplements, anti-aging treatments, wellness routines.
But have you ever asked yourself the question: What is collagen really used for? What your body expects from it (without you even knowing it)? We'll tell you everything!
Naturally present in the human body, collagen is a structural protein , much like steel in concrete: invisible, but essential. It alone represents approximately 30% of the body's total protein , and up to 80% of connective tissue .
What exactly is collagen?
The word "collagen" comes from the Greek word kolla , meaning glue. It is what connects and supports our tissues: skin, tendons, ligaments, cartilage, muscles, intestinal walls, blood vessels…
There are several types (I, II, III), but the most important for everyday use are:
Type I : skin, bones, tendons
Type II : cartilage
Type III : blood vessels, young skin
The problem? We lose them... as early as age 25.
From the age of 25-30, natural collagen production decreases by 1% per year . The result? Tissues lose elasticity, tone, and suppleness.
And this can be seen or felt through:
less firm , thinner skin
wrinkles that appear faster
joints that "creak"
slower muscle recovery
a more fragile digestion
brittle nails , dull hair
What is collagen really used for? What your body expects from it (without you even knowing it)
Here are the main roles of collagen , often underestimated:
1. Maintain the skin's elasticity and youthful appearance
Collagen forms a supporting framework for the skin. It's what makes it smooth, firm, and bouncy . When its levels decrease, wrinkles, fine lines, and sagging skin appear.
2. Strengthen the joints and tendons
It is the basis of articular cartilage : knees, hips, shoulders… A good reserve of collagen = more joint comfort, more mobility.
3. Support the muscles and bones
Yes, collagen is also present in muscles and bones ! It contributes to strength, recovery, and injury prevention .
4. Promote gut health
Collagen helps repair the intestinal lining , particularly in cases of permeability or chronic inflammation.
5. Improve the quality of hair and nails
Thicker, shinier hair, stronger nails? Thank you, collagen!
Why choose organic, porcine, and naturally flavored collagen?
At CrystalÔ , we have chosen to offer organic pork collagen, sourced from respectful farms, and flavored with certified organic lemon for a pleasant intake each morning.
✔️ Why this choice?
Porcine collagen is very similar to human collagen (better affinity, assimilation and bioavailability)
It has a more neutral taste than marine collagen
It is certified organic , without additives.
The aroma of organic lemon aids digestion and makes the treatment pleasant.
When and how should I take it to ensure it is effective?
You want to see results after a week... Sorry, collagen doesn't work miracles... It works thanks to regularity and the duration of the treatment.
Instructions for use:
2 teaspoons morning and evening
In a glass of cool or room temperature (not hot) water , a smoothie, juice—whatever you prefer. We recommend drinking it quickly, before it thickens.
For at least 12 weeks (3 months), the minimum to address collagen deficiencies.
In synergy with good hydration and natural vitamin C (acerola, lemon, parsley…)
Does everyone have to take it?
Not necessarily. But it can be useful:
from age 30 , as a preventative measure
after an injury , an operation , weight loss
during periods of intense stress , when regeneration is slowed down
in postpartum , to support connective tissues
to rebalance the acid-base balance
after age 40, as a continuous or seasonal treatment
For anyone wanting to improve the quality of their skin/hair/nails
For athletes, for their muscles, tendons and joints
For anyone wishing to improve joint comfort
What is the real purpose of collagen? What your body expects from it (without you even knowing it): in short, collagen is your silent ally!
Collagen isn't a trend. It's a cornerstone of your body's structure . And while it may be subtle, it's absolutely essential for maintaining a supple, stable, toned body... and radiant skin.
So, what is collagen for? To keep you upright, flexible, comfortable in your skin… and in your tissues !
Yours naturopathically, Frédéric
