Background
Nicotinamide adenine dinucleotide (NAD) is a crucial coenzyme involved in cellular energy homeostasis whose levels decline notably with aging, which has prompted interest in NAD+ boosting to help combat age-related diseases and dysfunction. Numerous clinical trials have demonstrated safety and efficacy for B3 vitamins, such as nicotinamide riboside (NR), to increase NAD+ levels and augment the NAD+ metabolome. Limited impact on clinically relevant outcomes or quality of life have been demonstrated, however.
Objective
This randomized, double-blind, placebo-controlled, remote pilot study examined the effects of supplementation with Qualia NAD+® on whole blood NAD+ levels and quality of life measures.
Methods
Study participants consumed Qualia NAD+ daily for 28 consecutive days. NAD+ levels were the primary outcome and measured using a self-administered, non-invasive blood spot assay test conducted at baseline and at study end. Quality of life questionnaires were the secondary outcomes and reported bi-weekly. NAD+ levels and questionnaire data were analyzed using a linear mixed-effects model to compare within-group and between-group differences over time as compared to baseline. Independent t-tests were utilized to compare safety and tolerability between study groups.
Results
Twenty-five healthy adults aged 40 - 65 (56% female) consumed Qualia NAD+ (n = 9) or placebo (n = 16) Overall, Qualia NAD+ significantly increased NAD+ levels an average of 74% compared to a 4% increase observed in the placebo group (p < 0.001). Within-groups comparisons for Qualia NAD+, and changes in NAD+ levels comparing Qualia NAD+ and placebo were also significant (p < 0.001). Improvements in the overall and somatic categories (p = 0.02 and p = 0.04) were observed for males only comparing baseline to the end of the study. No adverse events were reported.
Conclusions
Qualia NAD+, a novel nutraceutical formulated with multiple vitamins, nutrients, and botanical compounds, effectively increased whole blood NAD+ levels and may improve some symptoms of aging in males. Clinicaltrials.gov identifier: NCT06812416 .
