What is collagen?
A structural protein
Collagen is called a “structural” protein because it ensures the integrity of the skeleton. Thus, it contributes to the maintenance and cohesion of tissues, joint function, and muscle regeneration.
It also has beneficial effects on the skin by providing suppleness, firmness, and elasticity.
Abundantly present in the body, it is mainly found in bones, cartilage, muscles, tendons, and the dermis.
It is naturally synthesized by the body, but its production decreases with age. Tobacco, alcohol, and pollution can also impact collagen synthesis.
A dietary supplement
Supplementation is therefore interesting to compensate for this loss and replenish collagen reserves.
Dietary supplements are available in capsules, tablets, powder, or liquid form. Marin and bovine collagen are available on the market.

However, collagen has contraindications. Its consumption is not recommended for certain people. It can also cause side effects.
In which cases is it contraindicated?
In case of allergy
Depending on its origin, collagen may cause an allergic reaction. This can manifest as itching, difficulty breathing, and/or vomiting.
Bovine collagen, for instance, may cause a reaction in people allergic to animal proteins.
Generally, its consumption is discouraged for people with a food allergy, particularly to fish, shellfish, or eggs.
In case of hypercalcemia
This condition results in excess calcium in the blood. Taking collagen increases calcium levels and helps it adhere to bones.
It is therefore not recommended for people suffering from hypercalcemia. In case of other calcium metabolism disorders (hypocalcemia), consult a doctor.
In case of renal failure
This disease is characterized by kidney dysfunction. The kidneys no longer manage to filter blood and properly eliminate toxins from the body.
In cases of renal failure, it is advised to limit protein intake. When converted to urea, they heavily burden the kidneys and exhaust them.
What are its side effects?
Main side effects
Because it is already present in the body, collagen is generally well tolerated. Nonetheless, some may experience side effects such as:
- digestive disorders
- diarrhea
- constipation
- bloating
- gastric acidity
In most cases, these symptoms are mild and quickly dissipate. Otherwise, reduce the doses and/or frequency of intake.
Stop your consumption and consult a doctor if the side effects do not subside.
Usage precautions
To avoid potential side effects, always adhere to the dosage indicated by the manufacturer. You can also start with small doses and gradually increase based on your response.
Collagen intake should last 3 to 6 months maximum.
