Brief Summary

This interventional, double-blind, randomized, placebo-controlled pilot study aims to evaluate the effect of a dietary supplementation of a fish hydrolysate Peptidyss on sleep quality and anxiety.

Detailed Description

A total of 44 healthy participants (n=22 female, n=22 male) aged 35-60 years inclusive are included into the study, in a cross-over design. The participants will take both products, the fish hydrolysate Peptidyss and the placebo during a period of 4 weeks per product. The total duration of the study per participant is 127 days. The study visits are defined as Screening Visit and Study Inclusion (V0), Pre-Intervention-1-Visit (V1), Post-Intervention-1-Visit (V2), Follow-up-Intervention-1-Visit / Pre-Intervention-2-Visit (V3), Post-Intervention-2-Visit (V4) and Follow-up-Intervention-2-Visit (V5). The 4 weeks between V2 and V3 will serve as a washout phase between Intervention-1 and Intervention-2. No further follow-up visit is planned.

The primary objective is to evaluate the efficacy of Peptidyss® on sleep quality.

The secondary objectives are to evaluate the efficacy of Peptidyss® on sleep quality, anxiety, perceived stress and quality of life.

Dietary supplement : fish hydrolysate

The experimental product is a dietary supplement composed of a hydrolysate of fish containing low molecular weight peptides (4 capsules/day providing 1,4 g of fish hydrolysate)

Group Type: EXPERIMENTAL

Fish Hydrolysate

Intervention Type: DIETARY_SUPPLEMENT

The participants take 4 capsules/day of the study product. Two capsules should be consumed orally every morning with breakfast and/or with a glass of (plain, not sparkling) water and not with fruit juice or hot food/drink while ingesting the capsules; and two capsules should be consumed orally every evening with their dinner and/or with a glass of water.

Participants receiving the fish hydrolysate the fourth first weeks will then receive the placebo during another 4 weeks. A wash-out period of 4 weeks is included between each phase of supplementation.

Placebo

The placebo product containing mainly silica is presented in the same form as the active product, so that people handling the product cannot distinguish both formula (4 capsules/day)

Group Type: PLACEBO_COMPARATOR
