Storage Product description
Nicotinamide Adenine Dinucleotide (NAD+ ) is a naturally occurring coenzyme found in all living cells and is essential for cellular energy metabolism and redox reactions. It plays a critical role in mitochondrial function by facilitating electron transfer in oxidative phosphorylation, thereby supporting ATP production.
NAD+ levels naturally decline with age and under conditions of metabolic stress, which has driven increasing interest in NAD+ and its role in healthy aging, cellular repair, and metabolic regulation. As a key cofactor for enzymes such as sirtuins and PARPs, NAD+ is closely associated with longevity, DNA repair, and cellular resilience.
Product Application
Facial serums, creams, and essences
Dietary supplements (capsules, tablets, powders)
Functional foods and beverages
Medical nutrition and healthy aging formulations
The mechanism of NAD⁺ salvage pathway improve the function of skeletal muscle in aging. NAD⁺-Sirtuin1- FoxOs mitigates oxidative stress damage; NAD⁺-Sirtuin1- PGC-1α improves the mitochondrial function; NAD⁺-Sirtuin1-AMPK promotes autophagy; NAD⁺-Sirtuin2 reduces chronic low-grade inflammation and enhances the quantity and functionality of MuSCs; NAD⁺ increases vesicles, remodels endplate of NMJ.
Formulation Note
Cosmetic Formulations
Suitable for aqueous systems, emulsions, and advanced delivery systems such as liposomes or encapsulated formulations to improve stability and skin bioavailability. NAD⁺ is water-soluble and is typically incorporated into the water phase. It works synergistically with antioxidants and barrier-supporting ingredients such as niacinamide, hyaluronic acid, peptides, and ceramides.
The typical usage level of NAD⁺ in cosmetic formulations is: 0.05% – 1.0%, depending on formulation type, stability considerations, and desired efficacy.
Dietary Supplement Formulations
Commonly used in capsules, tablets, powders, and functional beverages. Due to stability and bioavailability considerations, NAD⁺ may be formulated alone or in combination with NAD⁺ precursors such as nicotinamide, NMN, or NR, as well as supportive nutrients like resveratrol and B vitamins.
For dietary supplement formulations, NAD-related ingredients are typically used to deliver an equivalent of: 100 – 500 mg per day, depending on product format, positioning, and target population. The final dosage should comply with applicable local food and dietary supplement regulations.
