Details and patient eligibility

About

A randomized, double-blind, placebo controlled, cross-over trial to investigate the effect of the Investigational Product "DailyColors™" (DC) on age-related pathways in adults.

The aim of this study is to measure the effects of acute treatment with DC on key pathways relevant to healthy ageing using blood biomarkers.

Based on power calculations a sample size of 20, is sufficient to detect an effect size of 0.46 at a power > 90%. To account for dropout the investigators will include 26 subjects in total.

Full description

Aims:

The aim of this study is to measure the effects of acute treatment with DC on key pathways relevant to healthy ageing using blood biomarkers.

Hypotheses:

There will be preliminary evidence that the IP has positive clinical effects on biologically relevant pathways related to healthy aging of brain and muscle including blood markers of inflammation, oxidative stress markers, and trophic factors.

Design:

A randomized, double-blind, placebo controlled, cross-over trial to investigate the effect of the Investigational Product (DailyColors™) on age-related pathways in adults. Participants will receive DailyColors™ or placebo for a week, then one week wash-out, and then placebo/Dailycolors™ for a week, in random order. In addition, participants will be invited to participate in an open-label extension study for 3 months.

Enrollment: 30 patients

Sex: All

Ages: 55 to 80 years old

Volunteers: Accepts Healthy Volunteers

• Subjects with unstable, life-threatening medical conditions
• Use of polyphenol or phytochemical supplements
• Use of dietary supplements last month, except from cod liver oil or other vitamin D supplements
• Vegetarians and Vegans
• Clinically significant abnormal laboratory results at screening
• Participation in a clinical research trial within 30 days prior to randomization
• Individuals with dementia and/or who are unable to give informed consent
• Individuals with unusual high intake of fruit, berries, vegetable and/ or coffee intake, > 5 portions of fruit, berries and/or vegetables per day or > 5 cups of coffee per day
• Any other condition which in the Investigator's opinion may adversely affect the subject's ability to complete the study or its measures or which may pose significant risk to the subject.
