Anyone looking to buy NMN often sees claims like “pure,” “high-quality,” “premium quality,” or “lab tested.” But how do you verify if such claims are actually well-founded? For that, you look at NMN certificates, also known as COAs: Certificates of Analysis.
A good NMN certificate shows whether a supplement has been tested for purity, identity, heavy metals, microbiological values, and other quality parameters. However, not every certificate is equally clear. Sometimes a batch number is missing, sometimes no laboratory is mentioned, and sometimes it is unclear if the report actually belongs to the product you are buying.
In this blog, we explain how you can approach checking NMN certificates. You will learn what to look for, which terms are important, and why transparency regarding lab tests is essential when choosing an NMN supplement.

Checking NMN certificates in brief
Checking NMN certificates means looking beyond marketing claims like “pure,” “premium,” or “lab tested.” You verify if a real certificate of analysis is available, which laboratory performed the test, and if the report belongs to the correct batch.
By making checking NMN certificates part of your selection process, you can better evaluate NMN supplements for transparency, purity, safety, and value for money.
What is an NMN certificate?
An NMN certificate is a document displaying the test results of an NMN product or NMN raw material. Such a certificate is often called a COA, or Certificate of Analysis.
A COA is intended to provide insight into the composition and quality of a product. With NMN, you primarily want to know if the product actually contains NMN, how pure it is, and if it has been checked for unwanted substances such as heavy metals or microbiological contaminants.
A good NMN certificate preferably contains information about:
- the tested product or sample;
- the batch number or sample reference;
- the date of analysis;
- the laboratory that performed the test;
- the analytical method used, for example, HPLC;
- the measured purity percentage;
- heavy metal testing;
- microbiological test results;
- a report number or reference code.
If this information is missing, it is more difficult to assess how strong the certificate actually is.
Why checking NMN certificates is important
NMN stands for nicotinamide mononucleotide. It is often discussed as a precursor to NAD+, a substance involved in processes related to energy metabolism and cellular functions. Because NMN is popular within the longevity market, many supplement brands have become active.
This growth makes transparency important. As a consumer, you want to know not only what is on the label, but also whether the quality has been independently verified.
By checking NMN certificates, you can better assess:
- whether the product has actually been tested;
- whether the test is recent and relevant;
- whether the test belongs to the correct batch;
- whether the purity has been clearly measured;
- whether it has been tested for heavy metals;
- whether microbiological values have been included;
- whether the brand is transparent about quality.
That is why at Every Day Better, we publish our available NMN certificates as clearly as possible. This allows you to verify for yourself how our NMN has been tested.
1. Check if the certificate is public
The first question is simple: can you even view the certificate?
A brand can say a product is “tested,” but if the report is not available anywhere, it is difficult to verify the claim. A public certificate is stronger than a general marketing phrase.
Watch out for formulations such as:
- “lab tested” without a downloadable report;
- “third-party tested” without a laboratory name;
- “99% pure” without a test method;
- “premium quality” without a COA;
- “certified” without a visible certificate.
Transparent brands make it easy to find the reports. For example, via a certificates page, a product page, or a downloadable PDF.
At Every Day Better, you can find the official reports on our NMN certificates and lab tests page.
2. Check the batch number
One of the most important parts of an NMN certificate is the batch number. A batch number refers to a specific production batch or delivery. This helps verify if the report belongs to the product you received.
A general certificate can be useful, but a batch-specific certificate is stronger. A batch-specific report provides more certainty that the test corresponds to the product actually being sold.
Therefore, pay attention to these questions:
- Is there a batch number on the certificate?
- Is the same batch number on the packaging?
- Is it clear when the batch was tested?
- Is the batch mentioned on the website?
- Is the report recent enough?
When you receive a jar or bag of NMN, it is wise to compare the batch number on the packaging with the information on the brand’s certificates page.
3. Look at the laboratory
A certificate is more reliable when it is clear which laboratory performed the analysis. Ideally, it should be an independent laboratory with experience in food, supplement, or raw material analysis.
Check if the certificate mentions:
- the name of the laboratory;
- the location of the laboratory;
- a report number;
- a test date;
- any accreditation or quality information.
At Every Day Better, the NMN reports are conducted by Intertek Food Services GmbH. Intertek is an internationally renowned testing, inspection, and certification company.

4. Check the HPLC purity
For NMN, purity is an important quality criterion. One of the best-known methods for measuring purity is HPLC, or High Performance Liquid Chromatography.
HPLC is an analytical method used to examine the composition of a substance. For NMN, this method is used to determine how much of the tested material actually consists of NMN.
If a brand says an NMN product is “99% pure,” you want to know:
- was this measured using HPLC?
- what exact percentage was measured?
- which laboratory determined this?
- on what date was the test performed?
- which batch does the result belong to?
Every Day Better lists HPLC purity values up to 99.63% for tested NMN batches on the certificates page.

5. Pay attention to heavy metals
Purity says something about how much NMN is in the product, but it doesn’t tell the whole story about safety and quality. Therefore, it is also important to check if the product has been tested for heavy metals.
For supplements, the following heavy metals are often checked:
- arsenic;
- lead;
- cadmium;
- mercury.
A good certificate or test report mentions not only that testing was done, but also what the measured values are. Sometimes values are below a reporting limit, for example, ” 0.02 mg/kg”. This means the substance was below the laboratory’s measurement or reporting limit.
On our NMN certificates page, you will also find information about additional checks for heavy metals.
6. Check microbiological values
In addition to heavy metals, microbiological checks are important. These tests look for the potential presence of bacteria, yeasts, molds, or other microbiological indicators.
For supplements, the following parameters may be relevant, among others:
- E. coli;
- Salmonella;
- yeasts;
- molds;
- coliform bacteria;
- total plate count;
- Clostridium perfringens;
- Pseudomonas spp.
Not every brand displays microbiological values equally clearly. However, this data can be important for better assessing the hygienic quality of a product.
At Every Day Better, we believe that product quality goes beyond just purity. That is why we also communicate about additional safety checks where available.
7. Check if claims are cautious
A reliable NMN provider is cautious with health claims. NMN is being researched for its relationship with NAD+, but that does not mean a brand can claim that NMN prevents, cures, or treats diseases.
Cautious formulations include, for example:
- NMN is a precursor to NAD+.
- NAD+ is involved in processes related to energy metabolism.
- Research into NMN is ongoing.
- Human long-term data are still limited.
- Quality and purity are important when choosing an NMN supplement.
Be more critical of claims such as:
- “rejuvenates cells”;
- “repairs DNA”;
- “prevents disease”;
- “guaranteed to slow aging”;
- “clinically proven against symptoms”.
At Every Day Better, we consciously choose cautious and informative communication. We do not present supplements as medicines and do not make medical claims.
8. Also compare the price per gram of NMN
A certificate says something about quality, but price remains important as well. Many NMN products are sold in different forms and quantities: capsules, powder, small packs, large packs, liposomal variants, or branded raw materials.
Therefore, it is better to look not just at the price per jar, but at the price per gram of NMN.
The formula is simple:
Price per gram of NMN = retail price / total amount of NMN in grams
For capsules, you can also look at:
- price per capsule;
- price per 500 mg dose;
- number of doses per package;
- total amount of NMN per package.
On our product pages, we make this calculation increasingly visible. For example, see our NMN Capsules 120x250mg or the NMN powder 30g.
9. Pay attention to product form: capsules or powder
NMN is usually available as capsules or powder. Which form fits best depends on your preference and routine.
NMN capsules
Capsules are convenient if you want fixed dosages. You don’t have to weigh anything and can easily take them with you. This suits people looking for a simple daily routine.
For example, view our NMN Capsules 120x250mg.
NMN powder
Powder is more flexible. You can dose it yourself and mix it with water or another drink. Powder can be interesting for people who prefer not to use capsules or who find the price per gram important.
