Do Collagen Supplements Work – A Detailed Analysis
Collagen holds the distinction of being the most prevalent protein within the human body. Its structure, reminiscent of fibers, serves the purpose of forming connective tissue.
As its name suggests, this type of tissue establishes connections between different tissues and is a crucial constituent in bones, skin, muscles, tendons, and cartilage.
Within food, collagen is naturally present solely in animal sources such as meat and fish, which possess connective tissue.
However, a diverse range of animal and plant-based foods provide essential collagen production components within our bodies.
But what about collagen supplements? Do collagen supplements work? This article aims to answer the question with a detailed science-backed analysis.
Different Types of Collagen Supplements
Initially, collagen debuted as an ingredient in skin creams and serums. However, even among dermatologists, doubts regarding its efficacy as a topical application arose because collagen is not naturally present on the skin's surface but rather in the deeper layers.
The structure of collagen fibers is too large to penetrate the outer layers of the skin.
Conversely, oral collagen supplements in the form of pills, powders, and specific foods are believed to be more efficiently absorbed by the body and have gained immense popularity among consumers.
These supplements are often marketed as Collagen Peptides or Hydrolyzed Collagen, indicating that the collagen has been broken down into more easily absorbable forms.
In addition to containing amino acids, which serve as the building blocks of protein, some collagen supplements may include additional nutrients that promote healthy skin and hair, such as vitamin C, biotin, or zinc.
How do Collagen Supplements work?
It is important to maintain a protein-rich diet to naturally enhance collagen production. Incorporating collagen supplements can provide additional benefits for the skin.
According to several nutritionists, consistent use of collagen supplements can help regulate skin function and prove advantageous in treating aging skin, particularly regarding marine collagen.
Collagen functions in two ways within the skin. It facilitates the cohesion of cells in the skin's connective tissue, thereby generating collagen, elastin, and hyaluronic acid. Marine collagen too exhibits anti-aging properties on human skin.
- Enhancing Skin Health
Many individuals who incorporate collagen supplements into their routine aim to enhance their skin's appearance and overall well-being.
There is a belief that collagen supplements can mitigate the effects of aging by improving skin moisture, reducing wrinkles, and enhancing elasticity.
What does the research indicate?
Research supports these assertions to some extent. For instance, a study published in the Journal of Medical Nutrition and Nutraceuticals involved several women consuming a blend containing vitamins, minerals, hydrolyzed collagen, and hyaluronic acid.
The results revealed a significant reduction in wrinkle depth among the women who consumed the mixture compared to those in the control group. Additionally, their skin hydration and elasticity showed significant improvement.
A recent clinical trial revealed a significant improvement in skin elasticity among women aged 35-55 who consumed marine collagen daily.
The same group of researchers also observed a notable reduction in skin wrinkles following the regular consumption of collagen hydrolysate.
Another study, featured in the journal Skin Pharmacology and Physiology, explored the effects of collagen supplements on women's skin.
Over eight weeks, the participants took either a collagen supplement or a placebo. At the end of the study, the women who consumed the collagen supplement exhibited higher elasticity and moisture levels in their skin.
Claims have also been made that collagen could help prevent skin conditions such as acne.
- Enhanced Muscle Mass
Research indicates that using collagen supplements may potentially contribute to an augmentation in muscle mass.
What does the research indicate?
Analysis conducted on a small group of 53 men unveiled compelling results regarding the benefits of collagen supplementation in conjunction with exercise.
During the study, participants were administered either 15 grams (g) of collagen or a placebo pill daily. Over 12 weeks, the participants engaged in regular exercise routines.
Upon completion of this period, those who received collagen supplements demonstrated a notably more substantial increase in muscle mass and strength than those who received the placebo pill.
The researchers postulated that collagen played a crucial role in stimulating the production of muscle growth-related proteins.
While this study presents promising findings, further research is imperative to comprehensively ascertain collagen's positive effects in terms of muscle growth.
- Prevents Bone Loss
Collagen plays a vital role in the composition of bones, contributing significantly to their strength and structure.
As individuals age, collagen production diminishes, weakening bones due to the insufficient collagen necessary for their support.
This decline in collagen can contribute to the development of conditions such as osteoporosis.
What does the research indicate?
Research suggests that consuming collagen supplements may have a preventive effect on bone density and strength deterioration.
In a noteworthy study, a group of women was divided into two groups: one taking calcium supplements alone and the other taking a combination of calcium and collagen supplements over one year.
The researchers observed that the women who consumed both calcium and collagen supplements exhibited lower levels of a protein responsible for the bone breakdown in their bloodstream.
However, further research is required to establish conclusive evidence regarding the specific impact of collagen on promoting and maintaining strong bone health.
- Promote Cardiovascular Well-being
Integrating collagen supplements into one's routine may support maintaining a healthy cardiovascular system.
What does the research indicate?
A study involving 30 participants shed light on the potential benefits of collagen supplementation for heart health. Half the participants were administered 16 g of collagen tripeptide daily for 6 months.
The reduction in arterial stiffness holds potential significance in fostering optimal heart health.
Nevertheless, additional research is indispensable in establishing comprehensive evidence regarding the specific effects of collagen on supporting heart health.
Are Collagen Supplements suitable for vegans and vegetarians?
Most collagen supplements are unsuitable for vegans and vegetarians because they are typically made from animal bones and protein.
Nonetheless, alternatives are available for those following a vegan or vegetarian lifestyle, although they may not be widely accessible and can often be found online.
Moreover, individuals adhering to a keto diet can also incorporate collagen supplements into their regimen.
Like vegan options, it is advisable to seek out a collagen supplement specifically formulated to support the requirements of a keto diet.
