Most NMN supplements hide behind proprietary blends or load capsules with unnecessary fillers. Dear Apothecary NMN takes the opposite approach: one active ingredient at a well-studied dose, in a clean capsule, with nothing you don't need. NMN (β-Nicotinamide Mononucleotide) is a naturally occurring compound and a direct precursor to NAD+, a coenzyme essential for cellular energy production and metabolic function. NMN supplementation supports the body's natural NAD+ biosynthesis pathway. Our formula delivers 500mg of NMN per serving in two easy-to-swallow veggie capsules. The other ingredients — rice flour and microcrystalline cellulose — serve as flow agents. That's it. No stimulants, no artificial colors, no trendy filler ingredients added to inflate the label.
