A Complete Guide to L-lysine  for Hair, Skin and Nails 


What is L-lysine?

L-lysine is an essential amino acid, meaning your body cannot independently produce l-lysine and it must be obtained from food on a regular basis. Amino acids are used to generate proteins in the body. One of these proteins is collagen, a structural protein that is important for skin healing and regeneration. Collagen is approximately 30% of all of our proteins in our body.  Lysine works in a series of biochemical reactions that produce more collagen in order to boost skin, hair and nail health.

A deficiency of lysine has been found to be associated with a decreased in wound repair.  Regular supplementation of lysine is important to ensure enough collagen to fight the signs of aging and collagen reduction. L-lysine is the most bioavailable form of lysine and is equivalent to the kind found naturally in L-lysine rich foods.  An added benefit of lysine is its potential ability to help boost calcium absorption.


Why is L-lysine in my product?

Malnutrition or a deficiency in micronutrients is reflected in our skin, hair and nails. Certain diets that restrict meats and animal proteins can also lead to a reduction in lysine intake. In addition certain disease states can lead to a reduced uptake of lysine from food. The addition of lysine to a regular supplement ensures this amino acid is readily available for absorption and conversion to collagen.


Our connective tissues in our body are all supported by collagen, These connective tissue fibers are responsible for ligaments, joints, bones, teeth, and all skin surfaces are dependent on collagen to remain healthy. Providing the body the tools to build collagen maximizes these connective fibers ensuring healthy hair, skin and nails. A lysine deficiency will contribute to a cellular imbalance. Preventing a deficiency is the first step towards optimizing connective tissue health. 


What is the Role of L-lysine for Hair?

Scalp shedding and dermatological issues can affect the hair follicle. Most information on causes of hair loss comes from situations or studies with known vitamin deficiencies. These provide clues to the importance of amino acids and proper gastrointestinal absorption for healthy hair. Inadequate amounts of lysine are linked to hair loss and hair fragility. This can be from limited or restricted diets, from other disease states that prevent adequate uptake of lysine or other micronutrient deficiencies. 

Supplementing lysine is a safe and effective way to provide the body with the amino acids that are required for hair production. As we age hair loss is estimated to impact most people at some point in their lives past the age of 50. Stress or poor nutrition also affects hair loss at any age. Regular lysine intake is required for prevention of hair loss. 


What is the Role of L-lysine for Skin?

Studies have shown that a reduction in collagen due to either age or UV exposure has a direct impact on skin firmness and wrinkles. It is hypothesized that improving collagen levels can delay or improve the signs of aging in skin.  

Collagen is known to decrease steadily as we age.  By decreasing this continuing loss there is evidence we may be able to delay the formation or wrinkles and skin sagging. L-lysine begins the process of building collagen and maintaining our supplies even as we age. By increasing the collagen in the skin, skin may appear with less wrinkles and improved tone and texture.

An additional benefit of l-lysine is to increase iron uptake in women. Low iron stores is a well known factor in hair loss. In addition to increasing collagen, lysine can help prevent another deficiency that may damage hair and ensure decreased hair loss.


What is the Role of L-lysine for Nails?

One added benefit of lysine is its potential ability to help boost calcium absorption.  These benefits help keep nails strong and resilient. 

The role of L-lysine in skin growth and repair ensures a strong nail bed and uptake of essential amino acids in the cells generating new nail growth. Small dietary changes can unexpectedly limit the supply of lysine for absorption. Taking a dietary supplement allows the freedom for any diet preference while still receiving all essential amino acids.

L-lysine is described as the anti-aging micronutrient. With its roles in protein production and calcium absorption it delays some of the most common effects of aging. It is considered essential for body processes. As we age and our diets change, it is possible that adults are regularly not receiving enough lysine.  A regular supplement contributes to overall body health and ensures continuing new collagen production.
