View quality documents ↓What Is NR Tartrate?
Nicotinamide riboside tartrate is a tartrate salt of nicotinamide riboside. The salt form is qualified by its identity, assay, moisture and storage profile rather than by the free-base identity alone. These are distinct salt forms. Specify the tartrate identity and assay basis, and compare counter-ion composition, moisture and formulation requirements rather than assuming equal weights provide an equivalent material. Product image: AI-generated ingredient illustration; actual batch appearance is subject to the sample and COA. PathGene NR tartrate powder is supplied from a chemical-synthesis process, followed by tartrate salt formation and powder isolation.

- Composition candidates:
- Screen microcrystalline cellulose or mannitol for capsules, disintegrants for tablets, and maltodextrin versus carrier-free sachets.
- Processing priorities:
- Calculate salt mass separately from NR equivalents; compare dry-blend uniformity and moisture uptake, then assess pH and NR-related degradants in liquids.
- Testing priorities:
- Salt identity, HPLC purity versus mass assay, water, NR assay, nicotinamide changes and packaged stability.
NR tartrate formulation development: composition, processing and validation
Composition candidates, processing sequences and tests support pilot design. Confirm candidate excipients and processes using this material in the actual finished formulation.
Solid formats: carriers, loading and mixing
- Define loading by ingredient mass, salt mass or active moiety. Use m = target mass / assay as supplied only when both share the same basis; convert dried-basis assays using water where appropriate, and do not substitute HPLC area purity for mass assay. Set excipient amounts from fill mass, bulk density and uniformity trials.
- Screen microcrystalline cellulose or mannitol for capsules, disintegrants for tablets, and maltodextrin versus carrier-free sachets.
- Record ingredient lots, actual component masses, loading bases and addition sequence, retaining blanks and single-ingredient controls for traceable changes.
Processing and formats: pilot batches through filling
- Calculate salt mass separately from NR equivalents; compare dry-blend uniformity and moisture uptake, then assess pH and NR-related degradants in liquids.
- Select blending/filling equipment for the actual format, recording size, bulk density, mixing time and fill mass; liquid or softgel routes need separate carrier, sedimentation and container/shell compatibility testing.
Validation and scale-up: tests, retained samples and packaging
- Salt identity, HPLC purity versus mass assay, water, NR assay, nicotinamide changes and packaged stability.
- Sample upper/middle/lower positions and start/middle/end filling; compare with ingredients, process blanks and single-ingredient results, documenting deviations and corrections.
- Include actual packaging, transport and intended storage in retained-sample plans; ingredient COAs and storage conditions do not establish a new finished-product shelf life.

Combination study with another NR saltNR + pterostilbene formulation research
A documented NR/pterostilbene combination offers a concrete benchmark for capsule and powder formulation work. Compare the declared NR active-moiety amount across salt forms, then screen blend uniformity, moisture uptake, oxidation, dissolution and shelf stability before selecting excipients or a delivery format.

Development rationale: A documented NR/pterostilbene combination offers a concrete benchmark for capsule and powder formulation work. Compare the declared NR active-moiety amount across salt forms, then screen blend uniformity, moisture uptake, oxidation, dissolution and shelf stability before selecting excipients or a delivery format.
Evidence scope: A randomized human trial studied a specific NR/pterostilbene product in adults aged 60–80; it does not establish equivalence for NR tartrate, this raw-material grade, a different ratio, or a new finished formula. Treat it as formulation precedent, not proof of synergy or a health claim.
Pilot checks: Retain individual-ingredient, blend and carrier controls; check uniformity and post-process assays before packaged samples, documenting study formulations separately from new candidates.

Scientific Research
2. Tartrate-salt crystallization and stability research
A 2021 materials study prepared and characterized nicotinamide riboside hydrogen-tartrate salts, including crystal structures, aqueous solubility and stability under different pH and temperature conditions. This supports salt-form and process research; it does not establish human bioavailability or clinical outcomes for this specific commercial material. Stereochemistry and salt stoichiometry should be checked against the supplied specification.

3. Human NR studies use a different salt form
Randomized human studies have examined nicotinamide riboside chloride and reported changes in blood NAD-related metabolites. Those results provide context for NR-pathway research, but chloride-form studies do not establish equivalent exposure or performance for NR tartrate.

Purity & Assay Method
The stated purity and batch result are shown separately. Confirm the method, dry-basis calculation and salt or hydrate form against the current COA.
Solubility & Formulation
Formulation work should confirm concentration, pH, light, moisture and hold-time controls for Nicotinamide Riboside Tartrate; suitability depends on the final format and market requirements.
What are the MOQ and pack options for NR tartrate powder?+
The raw-material MOQ for NR tartrate powder is 1 kg, with pack options of 1 g, 100 g, 1 kg, 25 kg.
Is NR tartrate interchangeable with NR chloride or NR hydrogen malate?+
These are distinct salt forms. Specify the tartrate identity and assay basis, and compare counter-ion composition, moisture and formulation requirements rather than assuming equal weights provide an equivalent material.
What specification is available for NR tartrate powder?+
Nicotinamide riboside tartrate, CAS 2415657-86-0, is supplied as a solid powder with an HPLC purity specification of ≥98.0%. It is the tartrate salt form of NR. The matching batch COA supports review of salt identity, purity and agreed quality items.
How should buyers compare the cost of NR tartrate, chloride and hydrogen malate?+
The powder mass of each NR salt includes a different counter-ion composition. Before comparing cost per NR component, verify salt identity, composition, water and assay basis, then calculate using the batch results. A kilogram price for one salt does not automatically represent the same NR quantity as another.
