Multi-ingredient supplement including omega-3s in 12-week RCT showed mixed effects on skin and self-reported outcomes.
A 12-week double-blind randomised controlled trial tested a multi-ingredient supplement regimen (containing omega-3 fatty acids plus collagen and other components) versus placebo in 35–65 year-olds. Outcomes included skin measurements, hair imaging, cognitive testing, and participant-reported sleep, energy, cognition, and sexual wellbeing. The abstract does not report which outcomes showed differences between groups or the direction or magnitude of effects.
