Marine collagen is a fibrous protein extracted from marine fish like salmon and cod. It is a great source of many nutrients and bioactive substances with the most commonly recognised including collagen. The term collagen usually makes us think of skin and anti-aging products, but it also supports and strengthens joint health. It comes as no wonder why many people with joint pain take collagen supplements to improve their quality of life.
What is Collagen?
Collagen is not only present in marine fish and other organisms; it is a naturally-occurring substance in a human body. Different cells in the body secrete collagen, particularly connective tissue cells. Collagen is found in bones, muscles, skin, blood vessels, tendons, and digestive system. All these areas of your body need collagen to do their job, which only emphasizes the importance of supplementation.
Factors that Affect Joint Flexibility
To truly understand what collagen supplementation can do for a person who experiences joint pain or discomfort (or even individuals who simply want to maintain joint health) we have to outline common factors that affect the flexibility and strength of joints.
- Overweight/obesity – carrying excess weight increases pressure on joints, thus causing pain and limiting a person’s range of motion
- Joint articulation – the way the bones, ligaments, tendons, and muscles are oriented in joint to permit certain range of motion
- Arthritis – in most cases, joint pain and inflammation are associated with arthritis. There are over a hundred types of arthritis with osteoarthritis and rheumatoid arthritis being the most prevalent
- Body asymmetry – usually occurs in individuals who play asymmetrical sports like baseball or tennis
- Age-related wear and tear – during natural process joints may lose their lubrication and a person starts experiencing pain when moving or performing daily activities.
Joint Health and Collagen
Have you ever felt like your joints are stiff when you try to move after sitting down for a while?
This can naturally happens with age due to loss of collagen. As we lose collagen, our tendons and ligaments find it more difficult to move as easily as they used to. In turn, an affected individual experiences more stiffness in joints, swelling, and pain. It is needless to mention pain, stiffness, and swelling prevent you from performing your everyday activities that affecting your quality of life.
Collagen is important for joints because it acts like glue that covers and holds bones together. The gel-like substance allows the ease of movements and supplementation can help you achieve this effect.
Scientists from the Penn State University carried out a study to investigate the effect of collagen on activity-related joint pain in athletes. They discovered that supplementation with collagen reduces the risk of joint deterioration in a high-risk group.
Besides the ability to prevent joint deterioration and help athletes improve their performance, collagen also proves to be effective in the management of osteoarthritis, the most common form of arthritis. Studies show that orally administered collagen stimulates a statistically significant increase in synthesis of extracellular matrix macromolecules by chondrocytes. These findings led scientists to conclude that supplementation with collagen is effective for osteoarthritis and other arthritic conditions. A study of patients with osteoarthritis-related joint pain discovered that collagen supplementation showed significant improvements in daily activities like walking up the stairs, sleeping, and general quality of life. Oral administration of collagen also benefits patients with rheumatoid arthritis.
Marine Collagen from NutriNZ
Daily intake of Marine Collagen from NutriNZ can really work to support overall joint health, strength and overall function. The supplement helps improve joint mobility, your range of motion, and decrease the intensity of pain, but it is also beneficial for active individuals who want to protect their joints from strenuous activity that can put additional and intense pressure on the body.
Furthermore, NutriNZ Premium Grade New Zealand Marine Collagen is made up of premium grade hydrolysed Type II Marine Collagen powder, sourced from the pristine coastal waters of New Zealand. The grains of the extracted Collagen are smaller than what is found in most other brands – which is important as it helps it to be absorbed faster.
The peculiar thing is that collagen tissues such as skin, bone and scales constitute about 30 percent of marine fish processing waste. So utilizing this extremely beneficial aspect of marine fish helps to offset what is perceived as waste in the fishing industry.
