Collagen, often called the body’s scaffolding, is the protein that literally holds us together.
Imagine it as the glue that binds our body’s structure, fortifying everything from our skin to our bones.
Collagen is not only abundant but also essential for maintaining the structural integrity of our connective tissues (Varani et al., 2006).
At the microscopic level, collagen is an amazing example of nature’s ingenuity.
It is made up of amino acids, which are the basic building blocks of proteins and is woven together in a distinctive triple helix structure.
This particular arrangement gives collagen the ability to be incredibly strong and elastic, which enables our tissues to endure stretching and stress.
It is the reason our skin bounces back when pinched and why our joints can move smoothly and withstand daily wear and tear.
Without sufficient collagen, our skin may become less elastic and more prone to wrinkles and sagging.
This natural decline, which typically starts in our mid-20s, can lead to some of the most visible and felt signs of aging.
Once plump and resilient, the skin starts to lose its elasticity, leading to wrinkles and fine lines.
Without sufficient collagen, our skin may become less elastic and more prone to wrinkles and sagging.
This is not just a cosmetic concern but a reflection of the deeper changes within our tissues (Shuster et al., 1992).
Joint discomfort is another common sign of aging linked to decreased collagen levels.
Our joints, which rely on collagen for cushioning and support, can start to feel the effects of years of movement and stress.
This can manifest as stiffness, discomfort, and decreased mobility, impacting our daily lives and activities.
But don’t worry; you can help your body maintain healthy levels of collagen by incorporating collagen-rich foods and supplements into your diet.
What are Collagen Supplements?
Collagen supplements have become increasingly popular in recent years as more people seek ways to improve their overall health and well-being.
Generally, collagen supplements are made from animal sources such as bovine, porcine, or marine organisms.
These sources are processed into smaller peptides for better absorption by the body.
The supplements come in different forms, such as powders, capsules, and liquids, and are marketed with various claims of improving overall health.
While collagen supplements are generally considered safe, it’s essential to speak with a healthcare provider before starting any new supplement regimen, especially if you have any underlying health conditions or concerns.
How Do Collagen Supplements Work?
When ingested, collagen peptides are absorbed into the bloodstream and distributed throughout the body.
These peptides can stimulate fibroblasts, cells responsible for collagen production in the skin, and chondrocytes in cartilage tissue, potentially promoting new collagen synthesis (Proksch et al., 2014).
This process can help replenish the declining collagen levels in the body, thereby contributing to tissue health and function.
Absorption and Bioavailability
The bioavailability of collagen peptides, meaning how effectively they are absorbed and utilized by the body, is a critical factor in their effectiveness.
Studies have shown that hydrolyzed collagen peptides have a high bioavailability due to their smaller size and are rapidly absorbed into the bloodstream after ingestion (Iwai et al., 2005).
This rapid absorption ensures that the peptides are available for use by the body’s tissues.
Benefits of Collagen Supplements
Anti-Aging Effects
Impact on Skin Elasticity and Hydration: Collagen supplements have been shown to improve skin hydration and elasticity significantly.
A study by Proksch et al. (2014) demonstrated that collagen peptide supplementation led to noticeable improvements in skin elasticity and hydration levels, attributed to the increased collagen density in the dermis.
Reduction of Wrinkles and Fine Lines: Regular intake of collagen supplements can also reduce the visibility of fine lines and wrinkles.
This effect is due to the ability of collagen to replenish the skin’s natural collagen stores, which diminish with age, thus improving the skin’s overall texture and appearance (Borumand & Sibilla, 2015).
Support for Joint Health
Collagen’s Role in Cartilage Regeneration: Collagen plays a vital role in maintaining the integrity of cartilage, the rubber-like tissue protecting the joints.
Supplementing with collagen has been found to support joint health by aiding in the regeneration of cartilage (Clark et al., 2008).
Studies on Joint Pain and Mobility Improvement: Clinical studies have shown that collagen supplements can significantly reduce joint pain and improve mobility.
This is particularly beneficial for individuals suffering from joint-related conditions like osteoarthritis (Benito-Ruiz et al., 2009).
Muscle Mass Building
Collagen’s Role in Muscle Repair and Growth: Collagen contains amino acids such as glycine and proline, which are essential for muscle repair and growth.
This makes collagen supplements particularly beneficial for athletes and individuals engaged in regular physical activity (Zdzieblik et al., 2015).
Research Findings on Collagen Supplements and Muscle Mass: Studies indicate that collagen supplementation, in conjunction with resistance training, can lead to an increase in muscle mass and strength.
This is attributed to collagen’s role in promoting the synthesis of muscle proteins like creatine and stimulating muscle growth after exercise (Jendricke et al., 2019).
What Types of Collagen Supplements Are Available?
There are multiple types of collagen supplements available, and each type can play a distinctive role in improving your joint, skin or overall health.
Additionally, different forms of collagen supplements, such as hydrolyzed collagen (powders and liquids) and undenatured type II collagen (found in specific joint supplements), vary in their absorption rates and efficacy.
Hydrolyzed collagen is generally considered more effective for skin and muscle-related benefits due to its high bioavailability.
In contrast, undenatured type II collagen may be more beneficial for joint health as it is thought to work through a different mechanism, potentially influencing immune responses in the joints (Bagchi et al., 2002).
BioCell Collagen
Composition and Unique Features: BioCell Collagen is a patented collagen supplement containing a unique hydrolyzed collagen type II matrix, chondroitin sulfate, and hyaluronic acid.
This combination is designed to support skin and joint health more effectively.
Scientific Studies and Findings: Clinical studies on BioCell Collagen have shown that it can significantly reduce skin dryness and wrinkles, as well as improve joint comfort and mobility (Schwartz & Park, 2012).
