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

What is L-proline?

Proline is an amino acid that is used to build many proteins in the human body. The protein collagen is made of a significant amount of proline. Collagen is the primary supportive protein in skin and connective tissue. It is also the most readily available protein in the human body. In order to have collagen, we need proline in our diet. Collagen is a vital component in maintaining youthful 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.


Why is L-proline in my product?

As we age the body can gradually produce less proline leading to a decrease in collagen production. Certain plant-based diets can also lead to a reduction in proline intake. The addition of proline to a regular supplement ensures this amino acid is readily available for absorption and conversion to collagen.

Collagen is the beginning cellular ingredient for healthy skin, hair and nails.  Skin, hair and nails are the biggest indicators of our nutritional status. Decreases in proline either through the effects of aging or of a particular diet are directly reflected in our outward appearance. Nutrient deficiencies of proline can be easily remedied by a daily supplement.


What is the Role of L-proline for Hair?

The role of collagen in stimulating hair growth has been an area of investigation and is widely popularized in several vitamins. A 2015 article has confirmed that a type of collagen is increased at the site of new follicular growth in wound healing. When a new dermal layer is being formed with new hair follicles after a wound, collagen is an essential component for rebuilding both the skin and hair follicles. This study confirmed that collagen is deposited in hair follicles, and a deficiency in collagen reduces hair growth.

By taking a regular supplement, l-proline supplies are kept at optimum levels to expand hair follicle generation and collagen production. Thinning hair does not have to be an expected by-product of getting older. Ensuring maximum amino acid availability can combat the hair thinning that can commonly be seen in the aging process.


What is the Role of L-proline for Skin?

It is estimated that collagen decreases at a rate of 1% per year.  Delaying collagen reduction is one of the tools to reduce wrinkles and reduce age related changes in the skin. By supplementing one of the main components to build collagen L-proline works to maintain collagen stores in the body.

Collagen is also used to promote wound healing and prevent tissue damage. A proline deficiency could lead to an overall delay in would healing and slow skin repair. Skin regeneration goes through different phases. L-proline  is involved in all phases and is increased at the site of would healing at a greater concentration than in plasma. This suggests the body actively transports proline to the dermal layer to form new skin.


What is the Role of L-proline for Nails?

Proline can be considered amino acid food for our nails. A 2017 study confirmed that supplementing diets with collagen led to a 12% increase in nail growth and a large (42%) reduction in broken nails in participants taking a regular collagen peptide supplement.  L-proline is one of the largest amino acids in collagen and has shown effectiveness in increasing the body’s own production of collagen when taken as a supplement.

L-proline has a well documented effect on building new collagen in the skin, hair, and nails. Collagen is a strengthening protein and can reduce the signs of aging associated with collagen reduction. As we are our natural collagen reserves are decreased, and our collagen production decreases as well.

L-proline is an amino acid and is involved in almost level of tissue repair and hair follicle development. Certain conditions can cause the body to produce less proline than might be needed to repair hair, skin, and nail problem areas. By taking a regular supplement  we can ensure that adequate amounts of this critical amino acid are readily available for the healthiest hair, skin, and nails possible.
