NMN certificates
On this page, you will find the NMN certificates from Every Day Better.
These NMN certificates provide insight into the purity, safety, and laboratory controls of our NMN products.
We publish our NMN certificates so that you can verify for yourself how our products have been tested.
Overall quality. Insured.
Nicotinamide mononucleotide, better known as NMN, is a molecule being researched for its relationship with NAD+ and processes surrounding energy metabolism. Because quality, purity, and safety are essential for supplements, we believe you should be able to verify exactly what you are buying.
That is why we have our NMN independently tested by specialized laboratories. On this page, you will find our NMN certificates, test results, and explanations of the controls used. This way, we provide transparency on how our NMN is tested for purity, heavy metals, microbiological values, and sensory quality, among other things.
At Every Day Better, we choose transparency: clear lab reports, verifiable test values, and as few empty claims as possible.

Why do we test our NMN?
At Every Day Better, we place great value on the quality and safety of our NMN products. We want our customers to be able to use our supplements with confidence, knowing that the products have been independently checked for important quality parameters.
Our NMN certificates are proof of our commitment to quality. The available reports provide insight into, among other things, the purity of NMN, the analysis method used, test date, lab reference, and additional checks for heavy metals and microbiological values.
Transparency is of great importance to us. That is why we not only share the certificates themselves but also provide explanations of what the test results mean. This allows you as a customer to better assess the quality you are buying and how our NMN is verified.
Every Day Better = Uncompromising quality
While many brands claim to be “pure” without clear substantiation, Every Day Better chooses openness. Our NMN is supported by independent test documentation and clear measurement results.
- Tested for purity, safety and sensory quality
- Analyzed by an independent, internationally recognized laboratory
- Transparent publication of available test reports and NMN certificates
- Insight into heavy metals and microbiological values
- No exaggerated medical claims, but a focus on verifiable quality
What does HPLC purity mean?
HPLC stands for High Performance Liquid Chromatography. This is a commonly used laboratory method for analyzing the composition and purity of substances.
For NMN, HPLC is used to determine how much of the tested material actually consists of NMN. High HPLC purity means that the product closely matches the expected NMN composition.
Our previously tested NMN batches show an HPLC purity of 99.5% to 99.63%.

Always check the batch number on your packaging. This way you can see which report belongs to the product you received. If your batch number is not on this page, please contact us so we can help you with the correct information.
Additional Intertek test 2026: heavy metals and microbiological safety
In addition to the HPLC purity analyses, an additional Intertek test was performed on safety parameters. This test is recorded in Intertek test report 26/32754/18918.
The analysis period ran from April 16, 2026, to May 6, 2026. The sample was described in the report as a white powder in foil packaging. The sensory assessment describes the sample as a free-flowing, white, and very fine powder without a noticeable odor.
Note: this additional report does not contain an NMN percentage or HPLC purity result. The report is intended as an additional safety and microbiological check.

What do these results mean?
The additional Intertek test shows that the examined white powder was checked for heavy metals and microbiological values.
In this report, the measured values for arsenic, lead, cadmium, and mercury were below the reporting limit of < 0.02 mg/kg. Also, Salmonella was not detected in 25 grams.
Other microbiological parameters, such as E. coli, yeasts, molds, coliform bacteria, coagulase-positive staphylococci, Clostridium perfringens, and Pseudomonas spp., were below the specified reporting limits.
This test supports our focus on transparency. We want to communicate not only about purity but also about relevant safety checks.
What is contained in an NMN COA?
A Certificate of Analysis, often abbreviated as COA, contains important information about the quality and testing of a supplement. For NMN, you can look for:
- Purity percentage, for example 99.5% or 99.63% NMN
- Confirmation of chemical identity via analysis methods such as HPLC
- Testing for heavy metals such as arsenic, lead, cadmium, and mercury
- Microbiological test results
- Date of analysis and lab reference
- Name and location of testing laboratory
- Batch information or reference to the examined sample
What is our NMN tested for?
1. Purity
Purity is measured using HPLC. This verifies whether the NMN meets the expected composition.
2. Heavy metals
Supplements can be tested for heavy metals such as arsenic, lead, cadmium, and mercury. These checks are important for assessing the safety of the product.
3. Microbiology
Microbiological tests check whether the product meets relevant hygienic quality standards. This includes checks for E. coli, Salmonella, yeasts, molds, and other microbiological parameters.
4. Sensory check
A sensory check looks at properties such as appearance, odor, and consistency. In the 2026 Intertek report, the sample was described as a free-flowing, white, and very fine powder without a noticeable odor.
Why do we publish our certificates?
We believe that transparency is more important than marketing claims. That is why we make our test results accessible to customers.
With public certificates, you can verify for yourself:
- which batch or sample was tested;
- which laboratory performed the test;
- when the test was performed;
- which method was used;
- what the measured purity is;
- whether safety checks were performed;
- which microbiological values were measured.
This makes it easier to compare NMN products objectively.
Comparing NMN quality: what should you look for?
Not every NMN product is substantiated in the same way. When comparing NMN supplements, look for the following points:
| Question | Why is it important? |
| Is a public certificate available? | Without a certificate, it is difficult to verify the quality. |
| Is the certificate batch-specific? | A general report says less than a report that belongs to your specific batch. |
| Is the lab name mentioned? | An independent laboratory makes the test more verifiable. |
| Is HPLC used? | HPLC is a suitable method for analyzing purity. |
| Have heavy metals been tested? | This is important for product safety. |
| Have microbiological values been tested? | This helps to verify the hygienic quality. |
| Is the price per gram of NMN clear? | This allows you to compare products fairly. |
At Every Day Better, we want to make this information as clear as possible.
No exaggerated health claims
At Every Day Better, we consciously choose clear and cautious communication. NMN is a precursor to NAD+, a substance involved in processes surrounding energy metabolism. Research into NMN is ongoing, but long-term human data is still limited.
That is why we focus on what we can concretely demonstrate: the quality, purity, and verifiability of our product.
Our promise
Every Day Better wants to offer NMN in a way that is transparent, verifiable, and honest.
Our promise:
- public laboratory reports;
- clear batch information;
- independent analyses;
- no exaggerated medical claims;
- clear explanation of purity and safety;
- transparency regarding quality and test results.
This way, you as a customer can judge for yourself whether our NMN fits what you find important.
