What is Melts™ NAD+ Dissolving Strips?
Nicotinamide adenine dinucleotide (NAD+) is a dinucleotide coenzyme rather than a peptide. Structurally it is composed of two nucleotide units, an adenine-bearing adenosine monophosphate moiety and a nicotinamide-bearing nucleotide, joined through a pair of bridging phosphate groups. In its oxidized (NAD+) state, the nicotinamide ring carries a positively charged pyridinium nitrogen, and the carbon para to that nitrogen is the reactive center responsible for accepting and donating a hydride during oxidation-reduction chemistry. This redox-active architecture distinguishes NAD+ from the amino-acid-based peptides and proteins that dominate much of the research-chemical catalog.
The Melts presentation delivers NAD+ within a fast-dissolving thin-film, or strip, rather than as a lyophilized powder. Each unit is a flexible polymer matrix in which the NAD+ material and flavoring excipients (Lemon Drop) are dispersed in a homogeneous film. The catalog format is a 30-strip pack. This is a finished, pre-formulated research article: the active material is already distributed throughout the film matrix at manufacture, so no weighing or dilution step is intended prior to a dissolution experiment.
NAD+ is broadly studied in biochemistry as a central coenzyme of cellular redox metabolism and as a substrate in enzymatic and cell-based research models, including work on NAD+-dependent oxidoreductases and NAD+-consuming enzyme families. In this catalog it is offered strictly as a research reference material for in-vitro and laboratory investigation. No physiological, therapeutic, or performance outcomes are described, claimed, or implied, and the material is not intended for diagnostic use or for human or animal use.
Reconstitution & handling
Unlike a lyophilized powder, a dissolving strip is a finished thin-film that does not require a reconstitution solvent or a weighing step; the NAD+ and its excipients are already dispersed within the polymer matrix. When a strip is placed in contact with an aqueous medium, the film-forming polymers hydrate and erode, releasing the dispersed NAD+ into solution — the relevant handling chemistry is film dissolution rather than solute reconstitution. NAD+ itself is a polar, water-soluble molecule, so aqueous or buffered aqueous systems are the appropriate media for any dissolution work; organic solvents are generally unnecessary and can complicate the film matrix. Because NAD+ in solution is sensitive to elevated pH and heat, dissolution is best performed in cool, neutral-to-slightly-acidic buffer, and any resulting solution should be handled promptly and kept chilled to limit hydrolysis of the labile nicotinamide N-glycosidic bond. Strips should be handled with clean, dry gloves and protected from ambient humidity until use, since the hygroscopic film can soften or prematurely dissolve on contact with moisture.
Storage & stability
In their sealed, moisture-protected packaging the strips are stable and should be stored in a cool, dry place away from direct light and humidity; refrigeration and desiccant protection help preserve film integrity and limit moisture uptake by the hygroscopic matrix. Once a strip has been dissolved in an aqueous medium, NAD+ is comparatively labile — it degrades under heat, alkaline conditions, and prolonged aqueous exposure — so any prepared solution should be kept cold, protected from light, and used promptly rather than stored long-term. Repeated exposure of the intact strips to warm, humid air should be avoided, as it can cause the film to soften, tack, or partially dissolve and can accelerate decomposition of the coenzyme.
How it's tested
Identity and purity of the NAD+ material are established by high-performance liquid chromatography (HPLC), which resolves NAD+ from related nucleotide impurities and hydrolysis products and supports the stated purity of >=99%. Chromatographic identity is typically corroborated by mass spectrometry (MS) to confirm the expected molecular species, and a Certificate of Analysis (COA) is available documenting the lot-specific purity result and analytical methods. These analytical checks verify the chemical identity and quality of the research material; they are physicochemical determinations and are not assessments of any biological activity.
