Niagen Bioscience Inc. has announced results from the first-ever randomized controlled trial examining Niagen®, the company's patented nicotinamide riboside (NR) supplement, in individuals with long COVID. The findings, published in The Lancet's eClinicalMedicine journal, indicate that daily supplementation with Niagen significantly increased NAD+ levels and was associated with within-group improvements in executive functioning, fatigue, depression, and sleep quality compared to baseline. The 24-week, double-blind, placebo-controlled study involved 58 non-hospitalized adults experiencing persistent symptoms following COVID-19 infection. Results from this clinical trial have already been presented.
