Development of an Innovative Health Ingredient From Marine By-products for the Healthy Aging

This interventional, randomised, placebo-controlled and double-blind study aims to evaluate the effect of a dietary supplementation with a blue fish hydrolysate derived from marine by-products, containing peptides and n-3 polyunsaturated fatty acids, on cognitive performance in a healthy older population, between 60 and 73 years old, with lower memory performance.

The main objective of this study is to evaluate the efficacy of a dietary supplementation with a hydrolysate derived from marine by-products compared to a placebo on the evolution of episodic memory at 3 months in healthy elderly people with lower memory performance. The secondary objectives of this study are to evaluate the efficacy of a dietary supplementation with a hydrolysate derived from marine by-products compared to a placebo on the evolution at 3 months of verbal recognition memory, working memory, perceived stress level, biological markers of nutritional and hormonal status in healthy elderly people with lower memory performance. Finally, participants' satisfaction with the product will be assessed. Participants have to take 4 capsules per day of the hydrolysate containing 770 mg (dose per capsule) or of the placebo for 90 days. Participants will have a phone screening interview and will attend 5 visits to the Bordeaux University Hospital on the Neuro-Psychopharmacological Research Platform.
