Over the years, the view of collagen and wellness has changed substantially. It was often overlooked, but today people are taking notice and seeking the benefits. Are you taking collagen and notice changes to your hair, skin and nails? Many of the amino acids in collagen may improve skin elasticity, growth of hair and nails and may provide additional beauty benefits. Adding collagen to your diet is a great way to stay on top of your self-care routine.
How do collagen supplements benefit skin?
Collagen Hydrolysate benefits the skin as it is easily absorbed into bloodstream as small collagen peptides or free amino acids. They travel all throughout the body including distribution to the dermis (which is a layer of skin). The skin is made up of two main layers: the epidermis and the dermis. Fibroblasts cells, found in the dermis layer of skin, produce collagen and elastin. These amino acids that have been absorbed into the bloodstream are the building blocks for collagen and elastin fibers, they also stimulate the production of new collagen, elastin and hyaluronic acid (3).
Ever wonder why your skin when pinched or stretched bounces back so fast? It’s because of Elastin! It is a protein in connective tissue that helps skin return to its normal position when enduring such things. Hyaluronic acid, which the body naturally produces, improves skin hydration since it helps to retain water within the cells of the skin and it also helps to maintain skin elasticity. Like collagen, as we age, the amount we produce diminishes. Therefore, increasing the amount of collagen, elastin and hyaluronic acid may result in tighter skin and less wrinkles.
One study found that after 3 months of taking a collagen hydrolysate-based supplement, participants had improved skin elasticity and dermal structure. Large pores and wrinkles were noticeably reduced as well*(1). Observations after a 6-week clinical trial where subjects took 10g of collagen hydrolysate once a day showed an increase in skin hydration, decreased formation of deep wrinkles and improved skin elasticity* (4). Consuming a collagen-based supplement along with vitamins A, C, E and zinc improved aged skin appearances* (1).
How do collagen supplements benefit hair and nails?
Great Lakes Gelatin Co. customers have reported increased hair growth, shinier, and fuller hair when taking collagen hydrolysate. If the hair follicle is still viable, there is a good chance that you will see new hair growth, but it can take months. Customers also have reported that their nails have become stronger, longer and less brittle. A 24-week study found that subjects had an increase in nail growth, a decrease in broken nails and an improvement in brittle nails. 80% of the participants agreed that there was an improvement in their nail’s overall appearance* (2).
There are several different amino acids in collagen that may aid with skin, hair and nails by preventing water loss and improving skin moisture as well as improving skin elasticity. With improved moisture and skin elasticity, skin may look less wrinkled and go back into place quickly after pinched or pulled. The free peptides may also help to make hair shinier, thicker, and aid in its’ growth as well as helping to make nails stronger and less brittle.
