Acin­na­mon sup­ple­ment can help against skin ag­ing, con­cluded bio­chemists at Osaka Pre­fec­ture Univer­sity in Ja­pan from a study in which they ex­posed skin cells to ex­tracts of ten ed­i­ble herbs in test tubes. If you’re a sup­ple­ments or cos­met­ics man­u­fac­tur­erer look­ing for prod­ucts to re­duce skin ag­ing, there are two fac­tors ors you need to take into ac­count: col­la­gen and IGF-1. Skin owes its sup­ple­ness and youth­ful­ness to a high level of col­la­gen syn­the­sis by the skin cells, and the hor­mone that stim­u­lates the skin cells to pro­duce col­la­gen is IGF-1. There are in­di­ca­tions that molecules in our food can en­hance the ef­fect of in­sulin – which in many re­spects re­sem­bles the ef­fect of IGF-1. That’s why th­ese re­searchers won­dered whether they could find th­ese molecules in ed­i­ble herbs. When the Ja­panese ex­posed skin cells to ten dif­fer­ent herb ex­tracts in test tubes, they no­ticed that fenugreek, cin­na­mon and Ira­nian cumin in par­tic­u­lar boosted col­la­gen pro­duc­tion. Cin­namalde­hyde in par­tic­u­lar en­hanced col­la­gen syn­the­sis, the re­searchers dis­cov­ered. Cin­namalde­hyde im­proves the per­for­mance of IGF-1, the re­searchers dis­cov­ered. They dis­cov­ered more phos­pho­ry­lated IGF-1 re­cep­tors in skin cells that had been ex­posed to IGF-1 rather than to cin­namalde­hyde. So cin­namalde­hyde doesn’t lead to the cre­ation of more IGF-1 re­cep­tors, but does en­sure that, once e IGF-1 has at­tached it­self to its re­cep­tor, that the sig­nal is trans­mit­ted bet­ter to the cell. The same ac­tu­ally also hap­pened in ex­per­i­ments with­out IGF-1, so it would seem that cin­namalde­hyde can re­place IGF-1 in skin cells. [Hmm... we won­der if cin­namalde­hyde does the same in mus­cle cells...] Ref­er­ence: J Agric Food Chem. 2012 Feb.
