| Abstract: | Dietary supplementation with collagen has been gaining popularity as an anti-ageing remedy. The aim of this randomised, double-blind placebo-controlled four-way study was to investigate and compare the effects of 12-week daily dietary supplementation with products containing 10 g hydrolysed fish collagen (HC) or a combination of 5 g or 10 g HC with 1.5 g methylsulphonylmethane (MSM) on dermis density in healthy human subjects. The secondary objectives were to investigate the effects on a variety of other skin parameters. The study results showed improved dermis density, skin texture and reduced wrinkles for all the active products. However, products containing MSM were superior in the improvement of skin thickness and roughness, and a higher dose of HC combined with MSM was crucial for improvement in hydration. On the other hand, no significant effects of the supplementation on viscoelasticity and transepidermal water loss were determined with any of the products. |

Dodajanje kolagena prehrane je vse bolj priljubljeno, dokazi na tem področju pa so omejeni. Cilj randomizirane, dvojno slepe, s placebom kontrolirane študije je bil raziskati in primerjati učinke 12-tedenskega dnevnega dopolnjevanja prehrane z izdelki, ki vsebujejo 10 g hidroliziranega ribjega kolagena (HC) ali kombinacijo 5 g ali 10 g HC z 1,5 g metilsulfonilmetana (MSM) na gostoto dermisa pri zdravih ljudeh. Sekundarni cilji so vključevali raziskovanje učinkov na različne druge parametre kože. Rezultati študije so pokazali izboljšano gostoto dermisa, teksturo kože in zmanjšanje gub za vse testirane aktivne izdelke. Izdelki z MSM so se izkazali kot učinkovitejše pri izboljšanju debeline in hrapavosti kože, višji odmerek HC v kombinaciji s MSM pa je bil ključen za izboljšanje vlažnosti. Po drugi strani pri nobenem od testiranih izdelkov nismo ugotovili pomembnih učinkov dopolnjevanja na viskoelastičnost in transepidermalno izgubo vode.;
