What to remember :
- Collagen is the most abundant protein in the human body.
- Marine collagen is one of the best sources of collagen.
- It has many health benefits for skin, joints and muscles.
- Taking marine collagen in the form of food supplements is highly recommended after a certain age to combat skin aging.
- Combine collagen with hyaluronic acid and vitamin C for long-lasting effects
What is collagen?
Collagen , the most abundant protein in the human body, is present in many tissues such as bones, joints, tendons, skin and many others.
There are several types, here are a few:
- Type 1 present in bones
- Type 2 present in cartilage
- Type 3 present in muscles and blood vessels
In addition, collagen has a toning action and hyaluronic acid helps smooth and hydrate the skin.
And what about marine collagen?
Marine collagen is collagen extracted from marine fish tissue. Unlike vegan collagen, animal-derived collagen has higher bioavailability and absorption rates. Furthermore, unlike bovine collagen, and according to several scientific studies, marine collagen has better absorption and avoids potential contamination caused by bovine spongiform encephalopathy.
Sources of marine collagen
Marine collagen is derived from the generally uneaten tissues of fish and crustaceans, such as skin, bones, and scales. Indeed, as in humans, this protein is found in the bone and cartilage tissues of these living beings.
This collagen is therefore mainly consumed in the form of broth or food supplements . The broth is prepared using these tissues which are immersed in water for several hours (6 to 24 hours) to which vegetables, herbs, spices are added to give more flavor. It is then filtered to be consumed as a juice, at the start of a meal.
The benefits of marine collagen
Marine collagen has many benefits for the body.
Due to its abundance in the body, it is essential to have sufficient quantities to compensate for potential losses.
Marine collagen and skin beauty
The skin is composed of almost 80% collagen . It can be subject to numerous external aggressions such as pollution, temperature, prolonged exposure to the sun, but also internal aggressions such as diet, stress, and an imbalance in the intestinal microbiota .
Over time, collagen density and synthesis decrease . Scientific studies attest to the effect of collagen on increasing the production of hyaluronic acid as well as strengthening the skin barrier. This strengthening helps keep the skin hydrated.
Marine collagen and anti-aging properties
Marine collagen, which has effects on elasticity and hydration, contributes significantly to combating skin aging . Indeed, aging leads to a loss of elasticity, density and collagen synthesis. Regular intake therefore helps to reduce the depth of wrinkles as well as strengthen the elasticity and density of the skin.
Collagen constituents protect against skin damage caused by exposure to UV-B rays.
Marine Collagen and Joint and Muscle Health
During aging, a reduction in muscle and bone function and mass occurs. This leads to greater fragility and ultimately to osteoporosis and sarcopenia.
Marine collagen acts as a cement block and therefore promotes bone formation by releasing specific molecules. In addition, marine collagen supplementation allows for better calcium fixation on bones.
Marine collagen also has benefits in increasing the rate of muscle protein synthesis and reducing the breakdown of these same proteins after sports.
Other effects are still being studied, such as strengthening capillary tissue and treating wounds and burns.
What are the dangers of marine collagen?
In the case of poor quality collagen, it is possible to experience some digestive discomfort. This is why we pay particular attention to the quality of our ingredients to promote good assimilation of the product and good effectiveness.
Apart from these digestive disorders, there is no risk of overdose .
Although adequate supplementation with collagen or collagen precursors can help protect against the development of cancer, it is important to remember that in the case of cancer that is already present, collagen can interact with cancer cells and activate their development.
Indications and dosage of marine collagen
Collagen production decreases with age , so it's important to keep your body supplied with it to promote healthy skin, joints, bones, and muscles.
To counter this loss of collagen, consuming foods rich in collagen , which are good for the skin, is a very effective solution. In addition, it is sometimes difficult to provide sufficient doses of collagen through food. This is why supplementation in the form of a food supplement to preserve the beauty of the skin based on marine collagen is strongly recommended.
For optimal effectiveness, it is essential to combine collagen with hyaluronic acid and vitamin C , a precursor of this protein.
An average of 3 months of supplementation is necessary to improve skin elasticity and hydration. The dosage is 2.5 to 10g of pure collagen per day . If included with other compounds, its dosage can be greatly reduced because these other compounds will stimulate its production and thus lead to a higher final dosage within the body.
NB: Collagen-based cosmetic products generally fail to reach the deeper layers of the skin and therefore have a transient and superficial effect. For long-term and deep effects, oral supplementation is much more suitable.
Bring marine collagen to your body with DIJO
At DIJO, we have developed our Radiant Skin , a true ally of skin beauty , to protect the skin from loss of collagen, elasticity and hydration. Prebiotics are the food of good bacteria, called probiotics , naturally present in our body. These good bacteria form our intestinal microbiota, this set of microorganisms which contributes to good digestive, immune, metabolic and cerebral health.
In addition, due to its optimal concentration of marine collagen , vitamin C ,hyaluronic acid , our Skin Focus is the ideal product for beautiful, healthy, invigorated skin.
⚠️Before any supplementation and in case of pathology or specific situation (pregnant woman, elderly person, allergies) it is important to seek advice from your doctor.
