How ker­atin has be­come a key in­gre­di­ent in sup­ple­ments for hair, skin, and nails.

Ker­atin is a pro­tein in our bod­ies that sup­ports the struc­ture of skin, nails, and hair, but a poor diet or sim­ply get­ting older leads to lower lev­els. Th­ese show up as dry and wrin­kled skin, brittle nails, and more frag­ile or thin­ning hair. Ker­atin has been an in­gre­di­ent in hair prod­ucts for many years, and more re­cently be­came avail­able in sup­ple­ments to boost lev­els— and beauty— from within.

The Break­through

Years of re­search led to a spe­cial process to make ker­atin ab­sorbable in sup­ple­ments. This form of ker­atin, called Cy­na­tine HNS is now found in many beauty for­mu­las, and has been shown to im­prove the health and ap­pear­ance of skin, hair, and nails.

To test out the eff ects of ker­atin on skin, re­searchers in Salt Lake City, Utah, com­pared the re­sults of 500 mg daily of a Cy­na­tine HNS ker­atin sup­ple­ment with a placebo among a group of 50 women. The study, pub­lished in the In­ter­na­tional Jour­nal of Cos­metic Sci­ence, mea­sured skin mois­ture, elas­tic­ity, wrin­kling, and over­all ap­pear­ance. Af­ter 90 days of daily use, women tak­ing ker­atin showed sig­nifi cant im­prove­ment.

In another study, pub­lished in The Sci­en­tific World Jour­nal, re­searchers from the U. S., Canada, and Aus­tralia col­lab­o­rated to test the same ker­atin sup­ple­ment for eff ects on hair and nails in a group of 50 women. They mea­sured hair loss, hair growth, hair strength, hair lus­ter, and amino acid com­po­si­tion, as well as nail strength and ap­pear­ance. Com­pared to a placebo, ker­atin pro­duced sig­nifi cant im­prove­ments in both hair and nails.

One mea­sure was a hair- pull test, mea­sur­ing how many hairs were lost on pulling. Among those tak­ing ker­atin, there was a 16.9 per­cent im­prove­ment af­ter 30 days, 38.9 per­cent im­prove­ment af­ter 60 days, and 46.6 per­cent im­prove­ment af­ter 90 days. Nail char­ac­ter­is­tics that were tested and showed sig­nifi cant im­prove­ments in­cluded hard/ soft, re­sis­tant/ frag­ile, bro­ken/ not bro­ken, rough/ smooth, and yel­low­ish/ white. All tests were car­ried out by li­censed der­ma­tol­o­gists.

Beauty Sup­ple­ment De­tails

In both of the above stud­ies, the daily sup­ple­ment tested con­tained 500 mg of Cy­na­tine HNS ker­atin plus 15 mg zinc, 1.65 mg cop­per, 18 mg vi­ta­min B ( niacin), 13.68 mg vi­ta­min B ( pan­tothenic acid), 2 mg vi­ta­min B ( pyri­dox­ine), and 300 mcg vi­ta­min B ( bi­otin). Com­bi­na­tions like th­ese are avail­able in mul­ti­ples brands of sup­ple­ments. Some for­mu­las also con­tain vi­ta­min C and other nu­tri­ents known to sup­port ker­atin pro­duc­tion and healthy skin, hair, and nails.
