OSTÉOCALM®, a unique formula
Marine collagen peptides, Promerim® Chondro
A product of Laboratoire Dielen research, this hydrolyzed marine collagen is produced in Brittany from a selection of fish caught in the North Atlantic. The original production process is patented by Laboratoire Dielen. It produces small collagen peptides known as "Low Molecular Weight" (LMW). These peptides weigh less than 1500 daltons.
These BPM collagen peptides have special properties because they are bioavailable, i.e. assimilable by the body. Their properties have been studied in studies published in scientific journals.
Promerim® collagen peptides® Chondro collagen peptides differ from other collagens in :
- Geographical origin: French (Brittany)
- Marine origin: selections of wild fish species
- Structure: low molecular weight (LMW) collagen peptides
- The production process: patented gentle hydrolysis
- Bioactivity: joint studies
Laboratoire Dielen has selected everyday fish species whose resources are not threatened. Their sustainable fishing in France is controlled by European regulations. These fish are not caught specifically for this production. Instead, Laboratoire Dielen extracts bioactive collagen peptides from certain collagen-rich by-products.
An active complex from 2 tablets a day
Osteocalm® and Dielen® Collagen are the only dietary supplements made with PROMERIM® collagen peptides. Several studies have demonstrated their benefits with a daily intake of 1 to 2 tablets. This sets them apart from other collagen powders packaged in jars or sachets, which often require higher, more expensive doses. Thanks to the PROMERIM® peptides contained in Ostéocalm® and Dielen® Collagen, high doses of hydrolyzed collagen are not necessary - 2 tablets a day are enough!
Developed by Laboratoire Dielen and produced in Brittany, these PROMERIM® marine collagen peptides are patented and distinguished by their very low molecular weight (700 Daltons), guaranteeing optimal bioactivity.
The properties of nutrients
Ostéocalm® nutritional complex has been studied in in vitro, in vivo and clinical trials in France and abroad.
Each nutrient in the formula is selected for its nutritional role:
- Calcium is needed to maintain normal bone structure
- Vitamin D contributes to theabsorption of calcium and phosphorus
- Vitamin C contributes to cartilage collagen synthesis
- Zinc contributes to normal protein synthesis
Dielen gastro-protective film coating
Osteocalm® tablets benefit from a film coating developed by Laboratoire Dielen. This protects the nutrients from gastric acidity by delaying their release into the intestine. The film coating uses no chemical additives, only gums of natural origin.
Health benefits :
Marine collagen peptides
Promerim® hydrolyzed collagen ® hydrolyzed collagen developed by Dielen is exclusively of marine origin. It is characterized by its high content of low molecular weight (LMW) collagen peptides. They are composed of 2 to 15 amino acids. Their low molecular weight is the source of their biological properties. The smaller the collagen peptides, the more bioavailable they are.
The benefits of collagen
Collagen is an abundant protein in the body. It plays an important role in joint cartilage:
- Collagen and cartilage
Cartilage is a smooth connective tissue between bones. It ensures the mobility of the bones in the joint. It is rich in collagen. Collagen helps maintain cartilage's strength and elasticity.
- Cartilage, the protector of joints
Cartilage forms a protective shield around the joints. It protects them from shocks and excessive pressure. It facilitates mobility.
Collagen for athletes and the elderly
From the age of 25, collagen production begins to decline. It is estimated that the average adult loses 1% of collagen every year. This natural aging process also affects motor function in bone and cartilage.
Deterioration of the collagen-rich cartilage can lead to a lack of flexibility and varying degrees of sensitivity. As a result, joint functionality and mobility are impaired.

The science behind it: Osteocalm® - The scientific proof of Laboratoire Dielen
Collagen is our body's most abundant protein. It accounts for 30% of total proteins in the human body. It's a protein naturally present in skin, tendons, bones, cartilage and ligaments. This protein ensures maintenance and solidity.
There are around 20 types of collagen in the human body, 3 of which are predominant in the organism:
- Type I collagen, found in tendons, bones, skin, ligaments and corneas.
- Type II collagen, found in cartilage.
- Type III collagen, found in muscles, internal organs and vessel walls.
Collagen is a large protein made up of 3 polypeptide chains. It cannot be assimilated in its present state.
Hydrolyzed collagen (HC), or collagen hydrolysate, is produced by hydrolysis. This process, which uses water and food enzymes, cuts the large collagen protein into segments called peptides.
The size and molecular weight of the segments or peptides depend on the hydrolysis process used. Peptides can be of varying sizes.
The "gentle" hydrolysis process developed by the Dielen laboratory produces small collagen peptides known as low molecular weight (LMW). Various scientific studies show that BPM collagen peptides are bioavailable and assimilable as they are.
*Vitamin C contributes to normal collagen formation to ensure normal cartilage function.
**Vitamin D and calcium help maintain normal bone and muscle function.
