    NMN Capsules OEM for Cellular Energy & Healthy Aging

    NMN (β-nicotinamide mononucleotide) is a direct precursor to NAD+, a critical coenzyme involved in energy metabolism, DNA repair, and mitochondrial function. NAD+ levels decline with age—by middle age, they may be half of early adulthood levels—leading to reduced energy and recovery. NMN enters cells and converts to NAD+, helping restore cellular efficiency. Research suggests potential in supporting cellular energy, cognitive function, healthy aging, and glucose/lipid metabolism, though human evidence remains limited. DUOZI NMN Capsules recommend 2 capsules daily with breakfast for three months. Suitable for middle-aged adults concerned about healthy aging and energy; not for pregnant/nursing women or those under 18.

    Curcumin, the active compound in turmeric, offers antioxidant, inflammation-modulating, and joint-support benefits. However, its poor absorption limits efficacy.

Positioned for joint comfort, flexibility, daily antioxidant support, and post-exercise recovery. Suitable for middle-aged adults, active individuals, and those preferring natural plant-based products. Recommended: 2 capsules daily with meals; assess after 2–3 months.
