Filter by:The aim of the randomized, double-blind, placebo-controlled, one-period effectiveness study is to compare the effects of multiple-dose 16 weeks daily dietary supplementation with 5 g collagen alone or 5 g of collagen in combination with hyaluronic acid on skin in healthy human subjects in comparison to placebo product. The main objective is to show that test products have beneficial effects on dermis density, and also on other skin parameters and to investigate differences in the effects among test products.
The aim of the randomized, double-blind, placebo-controlled, one-period effectiveness study is to compare the effects of multiple-dose 12 weeks daily dietary supplementation with 10 g collagen alone or 5 g or 10 g of collagen in combination with MSM on skin in healthy human subjects in comparison to placebo product. The main objective is to show that test products have beneficial effects on dermis density, and also on other skin parameters and to investigate differences in the effects among test products.
The double-center, randomized, placebo-controlled, one-period effectiveness study will include 30 subjects (women, aged between 25 to 55 years, Fitzpatrick phototype II and III). Subjects will be divided in two groups, 15 in each. One group (test group) will receive investigational product - lutein syrup (4 mg/mL; daily dose 20 mg) and the other (placebo group) placebo syrup. Participants will test continuous administration of placebo or investigational product for 12 weeks in order to demonstrate and assess multiple-dose effects. The primary objective is to assess the photoprotective potential of the investigational product in relation to placebo product. The secondary objectives are to assess effects of investigational product on dermis density and skin viscoelasticity after 12 weeks of dietary supplementation.
Placebo controlled double-blind multi-dose comparative study of the effects of coenzyme Q10 and collagen formulation with improved water-solubility in healthy adults. One group (test group) will receive investigational product - test syrup (daily dose 10 mL: fish collagen: 4000 mg, water soluble CoQ10 (Q10Vital®): 50 mg, vitamin C: 80 mg, vitamin A: 920 μg, biotin: 150 μg) and the other (placebo group) placebo syrup without those active ingredients. Participants will test continuous administration of placebo or investigational product for 12 weeks in order to demonstrate and assess multiple-dose effects on skin condition and signs of skin aging.
