Efficacy of the Marine Based Nutritional Supplement Peptidyss® on Sleep and Anxiety

Efficacy of the Marine Based Nutritional Supplement Peptidyss® on Sleep and Anxiety : a Randomized Clinical Trial With a Cross-Over Design in Healthy Adults

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.

Study Overview

• Status: Completed
• Conditions: Sleep Disorder
• Intervention / Treatment: Dietary supplement: Fish Hydrolysate; Dietary supplement: Placebo

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Peptidyss; 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)	Dietary supplement: Fish Hydrolysate; 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_COMPARATOR: 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)	Dietary supplement: Placebo; 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 Placebo the fourth first weeks will then receive the fish hydrolysate during another 4 weeks. A wash-out period of 4 weeks is included between each phase of supplementation.
