The Benefits of Collagen Supplements on Skin, Hair, and Joints

April 18, 2023 | Supplements and Nutrition

Collagen, a naturally occurring protein in the body, plays a vital role in maintaining the structure and elasticity of our skin, hair, and joints. With time, our body’s ability to produce this essential protein decreases, leading to various signs of aging and potential joint discomfort. To counteract these effects, many individuals opt for supplements containing this crucial protein, which come in a range of forms and sources. Understanding the importance of collagen and the different types available can help consumers make informed decisions when selecting the most suitable supplement to support their unique health needs.

What is Collagen?

Collagen is a family of fibrous proteins that provide strength and structure to various tissues in the body, including skin, hair, nails, bones, tendons, and ligaments. There are at least 28 different types of collagen, but types I, II, and III are the most abundant and well-studied. Type I is found primarily in the skin, bones, and tendons, while type II is predominantly present in cartilage, and type III is associated with skin, blood vessels, and internal organs.

Skin Health

The protein collagen is essential for maintaining the elasticity, hydration, and overall health of the skin. This vital protein forms a network of fibers that provide structure and support to the skin, helping to prevent sagging and the formation of wrinkles. As we age, our bodies produce less collagen, leading to visible signs of aging such as fine lines, loss of skin firmness, and the development of wrinkles.

Numerous scientific studies have demonstrated the benefits of taking supplements containing this crucial protein for skin health. In a study conducted in 2014, participants who consumed a hydrolyzed collagen supplement daily for eight weeks experienced a significant improvement in skin elasticity compared to a placebo group. Another study from 2015 discovered that women who took a supplement containing collagen daily for 12 weeks experienced a significant reduction in wrinkle depth and improved hydration levels in their skin. These findings highlight the potential advantages of incorporating collagen supplements into one’s skincare routine, particularly as we grow older and our natural collagen production declines.

Hair Health

Collagen also plays a vital role in maintaining the health of our hair. It provides the building blocks for keratin, which is the primary structural component of hair strands. In addition, this crucial protein supports blood circulation in the scalp, ensuring that hair follicles receive the necessary nutrients for growth and strength.

Although direct studies on supplementation and hair health are limited, anecdotal evidence suggests that supplements containing this key protein can improve hair thickness, strength, and overall appearance. This improvement is likely due to the protein’s role in supporting hair follicle health and providing essential amino acids for keratin production.

Joint Health

Collagen is a vital component of joint cartilage, providing strength and flexibility to the connective tissue. Age-related decline in collagen production can lead to joint discomfort and reduced mobility. Type II collagen supplements, derived from chicken or bovine cartilage, have been shown to improve joint health.

In a 2016 systematic review and meta-analysis, researchers found that collagen hydrolysate supplements significantly reduced joint pain in individuals with osteoarthritis. Another study from 2008 demonstrated that type II collagen supplements reduced joint pain and stiffness in individuals with rheumatoid arthritis.

Forms of Collagen Supplements

Supplements containing collagen are available in a variety of forms, such as powders, capsules, and liquid shots. A prevalent type of these supplements is hydrolyzed collagen, frequently referred to as collagen peptides. The production of hydrolyzed collagen involves breaking down the collagen fibers into smaller molecules known as peptides. This enhances the body’s ability to absorb and utilize the collagen, ensuring that the supplement is highly bioavailable.

These supplements can be sourced from a range of origins, including bovine (cow), porcine (pig), marine (fish), or chicken. Each source offers different types of collagen, providing distinct benefits for various aspects of health. Bovine-derived supplements primarily consist of type I and III collagen, which are beneficial for the health of skin, hair, and bones. On the other hand, marine-based supplements are rich in type I collagen, providing significant advantages for maintaining healthy skin.

In contrast, supplements derived from chicken contain type II collagen, which is known to support joint health. By understanding the differences in collagen types and their sources, consumers can make informed decisions when choosing the most suitable supplement to support their specific health needs.

Natural Collagen Generation via ch-OSA and Biotin

In addition to collagen supplements, natural collagen production can be supported through other dietary supplements such as ch-OSA® (choline-stabilized orthosilicic acid) and biotin.

ch-OSA is a highly bioavailable form of silicon, an essential trace element that plays a vital role in collagen synthesis. Research has shown that ch-OSA supplementation can improve skin elasticity and reduce the appearance of fine lines and wrinkles. A study from 2005 found that ch-OSA supplementation increased hair strength and thickness in women with fine hair.

Biotin, also known as vitamin H or vitamin B7, is a water-soluble vitamin that supports healthy skin, hair, and nail growth. Biotin is involved in the synthesis of keratin, the primary structural protein in hair and nails. Biotin deficiency can lead to hair thinning, brittle nails, and skin rashes. Supplementing with biotin has been shown to improve hair and nail health.

FitRenew, a powerful blend of clinically tested ch-OSA and biotin, is designed to boost your beauty from within. This unique formula supports collagen production, strengthens hair and nails, and promotes joint and bone health.


Collagen plays a crucial role in maintaining the health of our skin, hair, and joints. As we age, collagen production declines, leading to visible signs of aging and joint discomfort. Collagen supplements, along with other supportive nutrients such as ch-OSA and biotin, can help counter these effects and promote overall health and well-being. When choosing a supplement, consider the source and type, as well as the desired health benefits. As always, it is important to consult with a healthcare professional before starting any new supplement regimen.
