A Double-Blind, Randomised, Placebo-Controlled Study Evaluating the Effects of a Novel Multi-Targeted Dermatologist-Formulated Oral Supplement on Skin, Hair, Sleep, Energy, Cognition, Libido, and Longevity

This study evaluated the effects of a daily oral supplement regimen (Advanced ID Brain, Heart and Eye Omega Gel Capsules taken with Advanced ID Longevity and Collagen Complex Powder) on measures of skin condition, hair, sleep, energy, cognition and sexual wellbeing in healthy adults aged 35 to 65 years. Participants were randomised in a 2:1 ratio to receive either the active supplement regimen or a matched placebo regimen once daily with food for 12 weeks. Instrumental skin measurements, trained-assessor visual grading and participant questionnaires were performed at baseline (Day 0), Day 28 and Day 84. Hair imaging and cognitive testing were performed at baseline and Day 84. Whole blood samples were collected at baseline and Day 84 for exploratory epigenetic DNA biological clock age analysis, reported separately. The study was single-centre, sponsored by IDI Skincare Limited and conducted by Eurofins Product Testing Services Ltd (trading as Eurofins Alba) in Edinburgh, United Kingdom.
