NAD+ 500mg

NAD+ (Nicotinamide Adenine Dinucleotide) at a glance

Not a peptide at all, NAD+ is a dinucleotide: two nucleotides, one carrying adenine and one carrying nicotinamide, joined through their phosphate groups. Its molecular formula is C₂₁H₂₇N₇O₁₄P₂ and its molecular weight 663.43 g/mol. Cells build it from dietary forms of niacin and from tryptophan, and recycle it continuously through the salvage pathway. It appears in this catalogue alongside peptides mainly because it is sold in the same lyophilized-vial format.

Price and availability

Cyprus Peptides lists this single 500mg vial, shipped from Cyprus. The price is $255.00, or $0.51 per milligram of peptide. Across 10 brands listing NAD+ (Nicotinamide Adenine Dinucleotide) here, the middle half of prices falls between $0.035 and $0.14 per mg; this kit is above the typical range. Your payment waits in escrow until you confirm the parcel arrived, and only then is it released to the brand.

What it is studied for

NAD+ has two broad jobs. As a redox carrier, it accepts electrons during glycolysis and the citric acid cycle, becoming NADH, which then passes electrons to the mitochondrial respiratory chain. As a consumed substrate, it is cleaved by sirtuin deacylases, by PARP enzymes responding to DNA strand breaks, and by the ectoenzyme CD38. That second role links NAD+ supply to gene regulation, genome maintenance and immune signaling. Rising CD38 activity is one proposed explanation for the lower tissue NAD+ levels measured in older animals.

Research and regulatory status

The underlying biochemistry is textbook material and not in dispute. What remains uncertain is whether raising NAD+ from outside the cell produces meaningful outcomes. Animal studies of NAD+ and its precursors report effects on metabolic, muscular and neurological measures, while human trials, largely of precursors, have so far shown changes in blood NAD+ markers with modest or inconsistent functional results. Directly supplied NAD+ is a large charged molecule, and how cells take it up is still debated.

Checking the lab data

Because NAD+ is a small molecule rather than a peptide, identity is commonly confirmed by HPLC retention against a reference standard, supported by mass spectrometry consistent with 663.43 g/mol or by UV absorbance near 260 nm. Purity results should separate NAD+ from NADH, nicotinamide and ADP-ribose breakdown products. The powder should be white to off-white, and the report should specify whether the material is the free acid or a sodium salt.

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Concentration arithmetic: one 500 mg vial dissolved in 2 mL gives 250 mg/mL, or 500 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
