Effects of a Multi-Targeted Oral Supplement on Skin, Hair, Sleep, Energy, Cognition, Libido and Epigenetic Biological Clock Age

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.

Evaluation of the Effect of Seasonality on Biological Age in Adults

This research aims to provide insights on how seasonal variations influence biological age and enhance the design and analysis of long-term lifestyle interventions targeting biological clocks. Aging is a gradual decline in cellular and organ functions, significantly increasing the risk of non-communicable and infectious diseases. Recent research has focused on identifying aging biomarkers that can better predict functional capability in healthy individuals. Biological age clocks, which can be measured from samples like blood or saliva, are emerging as valuable tools for assessing the pace of aging and calculating age acceleration-the difference between chronological and biological age. These clocks utilize molecular and clinical data, including DNA methylation and plasma proteomics, to predict future health outcomes, such as disease risk and mortality. Various DNA methylation-based clocks have been developed, with the Dunedin Pace of Aging (PoAm) offering a more precise modeling of physiological changes over time. Lifestyle factors, including diet and physical activity, can influence age acceleration, suggesting that lifestyle interventions may impact biological aging. Current evidence indicates that three specific epigenetic clocks-PhenoAge, GrimAge, and Dunedin PACE-are particularly effective in detecting beneficial effects on aging trajectories. However, the stability of these clocks during long-term lifestyle interventions remains unclear, as they can exhibit variability over short periods and may be affected by factors influenced by seasonal changes, such as Vitamin D levels, climate, and white blood cells composition. To investigate these seasonal effects on biological age, a proposed observational study will track changes over a 12-month period in middle-aged and older adults.

Aging, Sleep, Cognitive Process

The aim of the study is to determine the impact of aging, circadian rhythms and sleep deprivation on executive performances. Volunteers will complete a 40-hour extended wakefulness period in constant condition (semi-recumbent posture in bed, constant dim light levels \< 10 lux, food and liquid intake at regular intervals) in order to control the circadian system. The volunteers will not be allowed to sleep in the sleep deprivation protocol ("high sleep pressure protocol") and will adopt a short wakefulness/sleep cycle (150/75 minutes) in the multiple nap protocol ("low sleep pressure protocol"). Tests and scales will be repeated every 3H45
