Definition
What is collagen?
Collagen is the most abundant body protein that is found in mammals, and more widely in the animal kingdom. Collagen fibers are the major constituents of connective tissues, skin, tendons, cartilage and bones.
Collagen is an extracellular protein which maintains the structural integrity and the mechanical properties of tissues and organs. Collagen is an insoluble protein.
Fully digestible, Rousselot® Hydrolyzed Collagen is a 97% pure protein made of all essential amino-acids, except tryptophan, which makes it very suitable as a protein source in functional foods, low sugar, and low carbohydrate products.

How is hydrolyzed collagen manufactured?
Rousselot® Hydrolyzed Collagen is manufactured by an enzymatic hydrolysis process from collagen.
It is carefully extracted through a strictly controlled and repeatable process.

What type is Rousselot Hydrolyzed Collagen?
As most of the hydrolyzed collagens comes from skins and hides, Rousselot® Hydrolyzed Collagen is Type I collagen, the same collagen as that found in human bones and skin.
What is the difference between Type I collagen and Type II collagen?
Collagen types are a biological classification.
Type I collagen is found in bones and skin. It accounts for more than 90% of organic mass of bone and is also the major component of skin, tendons and ligaments.
Type II collagen is the main collagen of cartilage. Purified collagen II does not exist by itself, only in combination with glucosamine & chondroitin. It is thus a different product.
Main characteristics of Rousselot Hydrolyzed Collagen
What is the amino-acid profile of RHC?
Rousselot Hydrolyzed Collagen benefits from a high source of typical amino-acids and contains all essential amino-acids except tryptophan. It is characterized by the predominance of glycine, proline and hydroxyproline which represent around 50% of the total amino-acid content.
This very specific composition of amino-acids provides hydrolyzed collagen with nutri-functional properties which cannot be found with other protein sources.

How to choose the best RHC for my application?
Depending on your application, Rousselot Hydrolyzed Collagen is available from different raw materials sources and different molecular weights.
To find the product better suited to your application, we recommend you to use the Product Finder.
What are the main dosage forms for using RHC?
Rousselot Hydrolyzed Collagen is a versatile and easy-to-handle product. It disperses quickly and dissolves promptly in cold water.
It can be formulated in powder blends, capsules & tablets, bars and drinks.
RHC & Nutrition
How does RHC contribute to weight management?
Proteins are known to be the most satiating macronutrient for animals or humans.
A 97% pure protein, RHC can be used in a blend with other proteins, animal or vegetable, to increase the satiety effect of enriched protein food such as meal substitutes, protein bars, soups…
Fat-free, cholesterol-free and carbohydrate-free, hydrolyzed collagen will assist the formulator in development work for balanced food, as it helps to maintain the body and the texture of reduced fat and sugar products.
What is RHC used for in sports and energy nutrition?
A good source of protein, fat- and sugar-free, Rousselot Hydrolyzed Collagen provides an essential source of protein to replenish the body’s need during and after strenuous exercise programs. RHC is a primary source of proline and glycine, two amino-acids that are the building blocks for cartilage.
It is thus widely used in protein-enriched products, such as sports drinks as well as cereal and protein bars, for which its protein content and amino-acids balance is particularly useful.

What is RHC used for in anti-aging nutrition?
Osteoporosis and osteoarthritis are major causes of disability during aging. Bones, joints and skin have a common component which is collagen. A supplement of

What is the maximum daily intake?
As an ingredient, Rousselot Hydrolyzed Collagen has no maximum daily intake. Nevertheless, it should not be used as a unique source of protein and, as all other ingredients, is to be included in a well-balanced diet.
RHC & Bone Health
What is osteoporosis?
Osteoporosis is a general disease of the skeleton characterized by a low bone mass and reduction of bone density. Consequently, bone fragility and risk of fracture are increased dramatically.
According to the International Osteoporosis Foundation, 30 to 50% of women and 20% of men will experience osteoporosis fracture after their 50’s.
How does RHC contribute to bone health?
Collagen represents 90 % of the organic mass of bone. Several studies have shown an increase in bone mass density with a supplementation of 10g per day of hydrolyzed collagen for a period ranging from 4 to 24 weeks.

RHC & Joint Maintenance
What is osteoarthritis?
Osteoarthritis is a degenerative disorder of the joints characterized by a loss of articular cartilage and a destruction of articular and peri-articular structures (bones, muscles). Osteoarthritis is also known as degenerative joint disease. Osteoarthritis may be classified as primary, when there is no obvious cause, or secondary, when preceded by a related disorder. The prevalence of osteoarthritis is higher among elderly people.
How does RHC contribute to joint health?
Several studies suggest the evidence that Hydrolyzed Collagen, thanks to its amino-acid composition (glycine and proline in particular), has a preventive and regenerative effect on the cartilage. There are multiple potential applications since the target population may vary from athletes (whose joints are subjected to stress), to elderly people (the group the most affected by osteoarthritis).

How much time is needed to see the first effects on cartilage?
Several communities have discussed the benefits of hydrolyzed collagen for preserving joint health. Most studies show effects within 3 months.
RHC & Beauty from Inside
How does RHC act on the beauty of the skin?
The lower hydration of the skin is responsible of the loss of elasticity and the development of wrinkles.
Some studies have shown that an oral intake of hydrolyzed collagen or gelatine can improve the water-binding capacity of the skin.
