Probiotics for enhanced tissue carotenoid status: A double-blind, randomized controlled trial.
The Journal of nutrition·July 10, 2026·PMID 42431406
Why it mattersCarotenoid status varies widely between individuals despite similar intake, and strategies to improve tissue deposition could optimize the health benefits of these phytochemicals. This study provides early evidence that a specific probiotic strain may modestly enhance skin carotenoid levels, offering a potential adjunct to dietary interventions for nutrition-focused clinicians.
