简要总结
Study to determine the effect of 12 weeks daily consumption of Superba Boost as compared to placebo on changes in Trans-Epidermal Water-Loss (TEWL).
详细描述
This study is a randomized, double-blind, placebo-controlled, parallel group trial in 70 healthy adult male and female subjects between 20 and 50 years. The primary objective is to assess whether Superba Boost krill oil administered at a dose of 1 g per day for 12 weeks (84 days) has a positive effect on the TEWL, skin hydration and elasticity. At screening, the subjects must have TEWL values of >10 g/m2/h and <24.9 g/m2/h when measured by a TEWAmeter, i.e. within the range defined as normal and healthy skin. The change in omega-3 index, defined as EPA and DHA as percentage of total fatty acids in red blood cells, will be measured and correlated to the changes in the skin parameters.
The study consists of 4 visits: the screening visit (V1), baseline visit / week 0 / Start of treatment (V2), Interim / Week 6 (V3) and week 12 / end of treatment (V4) . In this study, subjects must have a low habitual consumption of fatty fish and seafood, defined as a frequency of twice per month or less will be recruited. Each subject must fulfill all inclusion criteria and will not be allowed to meet any of the exclusion criteria.

结局指标
主要结局
12 weeks daily consumption of Superba Boost as compared to placebo on changes in Trans-Epidermal Water-Loss (TEWL) will be measured.
时间窗: 12 weeks.
Trans-epidermal water loss (the loss of water that passes from inside the body through the skin to outside the body) measured at baseline and after 12 weeks of intervention using a TEWAMetre will be considered. This measurement provides information on the integrity of the skin protective barrier functions. Subjects eligible for the study will have a TEWL value \>10 and ≤ 24.9 g/m²/h. In comparison, A TEWL value between 0-9 is classified as a "very healthy" barrier function and values between 25-34 are in the "strained" range. These participants will therefore be deemed ineligible for the study. Additionally, subjects with a TEWL value of \>35 will have a skin barrier function classified as "critical" and will also be ineligible for the study.
