1. What is Keratin?
Keratin is a fibrous structural protein found in many places throughout the human body, most notably in the hair, skin, and nails. It is crucial for providing strength, protection, and resilience to these biological structures.
1.1 Composition of Keratin
Keratin is composed of amino acids, which are the building blocks of proteins. The primary amino acids in keratin include cysteine, methionine, and glycine. The structure of keratin allows it to form a protective layer in the various tissues it comprises.
1.2 Types of Keratin
There are two main types of keratin: alpha-keratin and beta-keratin. Alpha-keratin is found in mammals, mainly in the hair and skin, while beta-keratin is typically found in birds and reptiles, providing them with feather and scale structure.
1.3 Sources of Keratin
While the body produces keratin naturally, there are additional sources such as keratin-rich foods, including eggs, nuts, and dairy products. These foods can help bolster the body’s keratin production.
2. The Role of Keratin in the Body
Keratin serves numerous essential functions in the human body. Understanding these is crucial for grasping the potential benefits of keratin supplements.
2.1 Structural Role
As a structural protein, keratin provides rigidity and strength. In the hair, it forms a protective layer against environmental damage, while in the skin, it helps prevent water loss and shields against microbial invasion.
2.2 Barrier Function
Keratin’s role in the skin also includes forming a barrier against environmental harm, making it essential for overall skin health and integrity.

Keratin aids in the growth and repair of tissues. In the scalp, sufficient keratin is vital for hair growth cycles, while in nails, it contributes to their strength and durability.
