Nutraceutical Ingredients · Ingredient Specification Guide

Guanjie Biotech supplies NMN Powder with an assay of ≥99.5% and CAS number 1094-61-7, as a white crystalline powder produced through freeze drying and vacuum drying. The ingredient is offered in three bulk densities — 0.15 g/ml, 0.55 g/ml and 0.75 g/ml — so a buyer can match the material to a solid-beverage line or to 0#/00# and 1#/2# capsule filling. Guanjie Biotech is an ingredient manufacturer founded in 2004 in Shaanxi, China, holding ISO 9001:2015, HACCP, Halal and Kosher certification and exporting plant extracts, fruit powders and specialised chemical raw materials to global supplement, food and cosmetics producers.

Why a Purity Number Alone Is Not Enough

NMN Powder is the powder form of nicotinamide mononucleotide, CAS 1094-61-7, used as a raw material in dietary supplement formulations. An assay figure tells a buyer how much active material sits in a gram of powder. It does not tell them how that gram behaves in a hopper, and it does not tell them whether the batch record will clear a finished-label review in the destination market.

Two very practical problems follow. The first is processability: powders that look identical on a specification sheet can behave differently on a capsule filler or a sachet line once bulk density and drying method diverge. The second is documentation: a certificate of analysis that does not match the delivered lot, or a certification whose registered scope names a different product, will stall an order at the quality gate rather than at the purchase order.

Evaluation therefore splits into three concrete questions. Will this specification run on my dosage form? Can the supplier hand me the documentation to prove what is in the drum? And can the same specification be repeated on the next delivery? The sections below answer those three questions against the NMN Powder data Guanjie Biotech publishes.

The Regulatory Baseline Behind NMN Today

The market-access picture shifted in late 2025. As of 29 September 2025, the U.S. FDA confirmed that NMN is not excluded from the definition of a dietary supplement, which effectively clears its marketing as a supplement in the United States (source: Venable LLP summary of the FDA decision, October 2025). That removed a live legal uncertainty from the buyer's risk register. It did not remove the manufacturing expectations that sit underneath it.

FDA states that companies which manufacture, package or hold dietary supplements must follow current good manufacturing practices intended to help ensure identity, purity, quality, strength and composition. For a substance treated as a new dietary ingredient, FDA also describes a pre-market notification process involving safety information, unless an applicable exception applies.

The practical consequence is that supplier screening has become largely document-driven. The question is no longer whether a supplier can talk about NMN, but whether it can produce a signed certificate of analysis for the exact lot and show a valid certificate whose registered scope covers the material being bought. Buyers in the research and evaluation stage should treat those two documents as the entry ticket, not as the closing paperwork.

How Guanjie Biotech Defines Its NMN Powder Specification

Guanjie Biotech publishes the NMN Powder specification as a fixed set of parameters rather than a single purity claim. The data sheet below is the version a formulation team can actually work from, because it separates identity, purity, physical form and commercial terms.

NMN Powder is supplied as a stable white crystalline powder without harmful solvent residues.

The data sheet at a glance

Drying method is a processing decision, not a footnote

Freeze drying and vacuum drying are not interchangeable labels on a marketing page. They are the reason the same molecule arrives at three different bulk densities, and bulk density is what decides how the powder moves through a filler.

The lowest density, 0.15 g/ml, comes from freeze drying and is positioned for instant solid beverages, where a light, fast-dispersing powder is an advantage. The middle density, 0.55 g/ml, comes from vacuum drying and is positioned for size 0# and 00# capsules. The highest density, 0.75 g/ml, also vacuum-dried, is positioned for size 1# and 2# capsules. A buyer who orders on assay alone and ignores density can end up with a powder that meets the certificate and still runs badly on the line.

Quality control and batch documentation

Guanjie Biotech operates its own manufacturing facilities and testing laboratories, with a 7,000 m² site that includes a 2,000 m² cGMP-standard clean workshop and a 500 m² laboratory. The company reports a 100% test policy and a research and development team of seven engineers, supported by more than 16 national patents.

In-house testing supports the certificate of analysis issued with each NMN Powder batch.

For a buyer, the useful part of that infrastructure is the paperwork it produces. Each shipment is accompanied by a certificate of analysis that matches the agreed specification, and where a quality discrepancy appears on arrival, the company states that it works with third-party laboratories such as SGS and Eurofins to resolve technical audits and verify product specifications.

Certification scope that actually names NMN Powder

Certification is only worth the paper it is printed on if the registered scope covers the product being purchased. That is the specific check to run on NMN Powder, because a supplier can hold a valid certificate for plant extracts and still not have the NMN line inside its scope.

ISO 9001:2015 certification, issued by China Quality Certification Centre (CQC).

At Guanjie Biotech, two of the four certificates explicitly list NMN Powder inside the covered product portfolio: the HACCP certificate and the Kosher certificate. The HACCP certificate covers export trade of plant extracts, solid beverages and food additives, and its named product portfolio includes NMN Powder. The Kosher certificate is issued under Kosher Dietary Law by Badatz Shatz (SKS) and likewise names NMN Powder among the covered extracts.

Seven Checks Before You Confirm an NMN Order

The sequence below is written for a buyer moving from research into evaluation. Each check produces a document or a decision, so the file you hold at the end is defensible to an internal quality team.

1. Fix the dosage form first. Decide whether the NMN Powder is going into hard capsules, a powder sachet, an instant beverage or a functional food matrix. The dosage form, not the price list, determines which density you should request.
2. Select the bulk density against the filler. Request 0.15 g/ml for instant solid beverages, 0.55 g/ml for 0# and 00# capsules, or 0.75 g/ml for 1# and 2# capsules. Ask the supplier to confirm the density of the actual lot, not the catalogue average.
3. Request the certificate of analysis for the specific lot. The COA should state assay, appearance and the analytical method used, and it should match the batch number printed on the drum. A generic COA without a lot number is not a batch record.
4. Verify certification scope and expiry. Confirm that the certificate names NMN Powder, note the certificate number and issuing body, and check the validity window against your planned production date.
5. Confirm packaging and OEM terms. Guanjie Biotech offers OEM / ODM packaging, so the pack format, label content and fill weight can be agreed before the first production batch rather than after.
6. Run a sample through your own process. The minimum order quantity of 1 kg allows a genuine trial: fill a short capsule run or a sachet run and record flow, fill-weight variation and dispersion behaviour.
7. Lock lead time and capacity into the plan. With a stated lead time of 30 days and a monthly capacity of 30 tons, place the first commercial order against a production date rather than against a stock assumption.

Where Each Density Actually Runs

The same NMN Powder specification serves several product categories, but the physical form changes with the application. These are the pairings that matter at the evaluation stage.

Hard capsules

Capsule filling is the most density-sensitive application. The 0.55 g/ml vacuum-dried grade is positioned for size 0# and 00# capsules, while the 0.75 g/ml vacuum-dried grade is positioned for size 1# and 2# capsules. Choosing between them is a matter of target fill weight and capsule size, and it should be settled with a trial run before a bulk order is raised.

Instant solid beverages and powder sachets

The 0.15 g/ml freeze-dried grade is positioned for instant solid beverages. A low-density powder disperses readily in a stick pack or sachet format, which is why the beverage application and the freeze-dried route are usually specified together.

Functional foods, nutricosmetics and sports nutrition

Beyond capsules and sachets, NMN Powder is listed for dietary supplement, health food, beverage and cosmetics use. In practice, formulators place it in functional food and confectionery formats, nutricosmetic concepts and sports and performance nutrition blends, where the powder is combined with other actives before tableting, blending or filling.

Packing is carried out in-house, with OEM / ODM packaging available for NMN Powder orders.

These two tables summarise the decision points that most often cause a purchase to be reworked. Both are built only from published product data and certificate records.

Certification records held by Guanjie Biotech

One timing detail is worth flagging for buyers planning production into late 2026 and beyond: the ISO 9001:2015 and HACCP certificates both expire in December 2026. When those documents sit in a supplier questionnaire, ask for the renewed certificate or the recertification audit status alongside the current copy. The Halal and Kosher certificates run to 2027.

Conclusion

NMN Powder is a specification-led purchase, not a purity-led one. The assay of ≥99.5% and CAS number 1094-61-7 establish identity, but the drying route and bulk density decide whether the material fills a 0# capsule or disperses in a sachet, and the certification scope decides whether the batch clears a quality review. Guanjie Biotech publishes all three dimensions: three densities at 0.15 g/ml, 0.55 g/ml and 0.75 g/ml, a 1 kg minimum order quantity with a 30-day lead time, and a certificate set in which HACCP and Kosher both name NMN Powder.

The evaluation work is therefore simple to describe and easy to skip: match the density to the dosage form, confirm the certificate scope covers the material, and check the expiry dates against your production calendar before the order is confirmed rather than after.
