NPQ Plus Supplementation for Skin Health and Antioxidant Status

Effects of NPQ Plus Supplementation on Skin Health, Antioxidant Status, Fatigue and Self-Perceived Well-being: A Single-Arm Prospective Interventional Study

This study evaluated the effects of NPQ Plus supplementation on skin health, antioxidant status, fatigue, and self-perceived well-being in healthy adults with skin concerns. NPQ Plus is a multi-component nutraceutical formulation containing polyphenols (Oligonol®), nicotinamide mononucleotide (NMN; RevAge®), pyrroloquinoline quinone (PQQ; PureQQ®), coenzyme Q10 (CoQ10), and a trace mineral complex (Ioniplex), which are known to possess antioxidant and cellular protective properties.

This was a single-arm, open-label, prospective interventional study involving 55 participants. Subjects consumed one sachet of NPQ Plus daily for 12 weeks. Assessments were performed at baseline and at Weeks 4, 8, and 12. Skin health was evaluated using the Patient-Oriented Eczema Measure (POEM), visual analogue scale (VAS), and objective skin biophysical measurements including skin elasticity, hydration, transepidermal water loss (TEWL), pigmentation, inflammation, and sebum secretion. Antioxidant status was assessed by measuring total antioxidant capacity (TAOC), malondialdehyde (MDA), 3-nitrotyrosine (3-NT), and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Fatigue symptoms and self-perceived improvements in skin health, sleep quality, and overall well-being were also evaluated.

Skin aging is influenced by intrinsic aging processes and environmental stressors, including ultraviolet radiation, pollution, and oxidative stress. These factors contribute to impaired skin barrier function, reduced hydration and elasticity, inflammation, pigmentation changes, and increased oxidative damage to lipids, proteins, and DNA. Nutraceutical supplementation containing antioxidant and mitochondrial-supporting bioactive compounds has emerged as a potential strategy to mitigate these changes by enhancing endogenous antioxidant defenses and supporting cellular repair mechanisms.

NPQ Plus is a multi-component nutritional supplement comprising polyphenols (Oligonol®), nicotinamide mononucleotide (NMN; RevAge®), pyrroloquinoline quinone (PQQ; PureQQ®), coenzyme Q10 (CoQ10), and a trace mineral complex (Ioniplex). These ingredients have been reported to possess antioxidant, anti-inflammatory, and mitochondrial-supportive properties that may improve skin condition, reduce oxidative stress, and alleviate fatigue.

This completed study employed a single-arm, open-label, prospective interventional design. Fifty-five healthy adults with skin concerns were enrolled and instructed to consume one sachet of NPQ Plus daily for 12 weeks. Clinical assessments were conducted at baseline and after 4, 8, and 12 weeks of supplementation.

The primary evaluations included objective skin biophysical measurements using the Multiprobe Adapter (MPA) system, consisting of skin elasticity (Cutometer®), skin hydration (Corneometer®), transepidermal water loss (Tewameter®), skin inflammation and pigmentation (Mexameter®), and sebum secretion (Sebumeter®). Patient-reported skin outcomes were assessed using the Patient-Oriented Eczema Measure (POEM), visual analogue scale (VAS), and self-perceived improvements in skin health.

Systemic antioxidant status and oxidative damage were evaluated using saliva biomarkers, including total antioxidant capacity (TAOC), malondialdehyde (MDA), 3-nitrotyrosine (3-NT), and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Fatigue was assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) Scale, while participants also reported changes in sleep quality and overall well-being.

The study aimed to characterize longitudinal changes following NPQ Plus supplementation across multiple domains, including skin health, antioxidant status, fatigue symptoms, and participant-reported outcomes, over the 12-week intervention period.
