New Forces in Anti-Aging: A Comparative Analysis of Three Ingredients
NMN: Energizing Core of Metabolism
As a direct precursor of NAD⁺, nicotinamide mononucleotide (NMN) delays aging through multiple pathways.
Its primary mechanism is raising intracellular NAD⁺ levels, thereby activating sirtuin proteins that orchestrate mitochondrial biogenesis and metabolic homeostasis.
NMN also boosts PARP1 activity, accelerates DNA-damage repair, preserves telomere length and dampens aberrant expression of senescence-related genes.
In animal studies NMN improves vascular function and skeletal-muscle mitochondrial performance, crosses the blood-brain barrier and safeguards neurons.

PQQ: Fortifying Antioxidant Defenses
Pyrroloquinoline quinone (PQQ) excels as a potent antioxidant. It markedly increases the activities of SOD, GSH-Px and CAT, efficiently scavenges ROS and curbs accumulation of oxidative products such as MDA and NO.
Concurrently, PQQ suppresses release of inflammatory cytokines (IL-1β, IL-6), mitigating chronic low-grade inflammation.
Experiments in aging rats show that medium-to-high-dose PQQ restores appetite and mobility, protects thymus and spleen mass, and slows immunosenescence-delaying aging via combined antioxidant and anti-inflammatory actions.

Glutathione: Targeting Skin Aging
Glutathione anti-aging action is centered on skin health.
Both reduced (GSH) and oxidized (GSSG) forms inhibit melanogenesis, lowering melanin index and UV-spot count.
GSH also reduces wrinkle depth, improves elasticity and ameliorates photo-aging phenotypes, with benefits especially pronounced in subjects over 40.
Clinical trials demonstrate that 250 mg/day oral glutathione is safe and well tolerated, delivering whitening and anti-aging effects by modulating cutaneous oxidative stress and metabolism.
Distinct yet complementary, the three ingredients follow different anti-aging routes:
- - NMN provides systemic metabolic regulation and multi-organ protection, suited for whole-body aging intervention.
- - PQQ emphasizes antioxidant defense and immune modulation, ideal for individuals with prominent oxidative stress.
- - Glutathione specializes in localized skin rejuvenation, meeting the demand for brightening and wrinkle reduction.
