At Deutsches Test Institut (DTI), products are assessed holistically from a consumer perspective. For foods and dietary supplements, the performance of the test requires the manufacturer to provide corresponding external laboratory analyses. DTI does not conduct its own laboratory analyses. The submitted documents are not verified in terms of their content, but are assessed exclusively from a consumer perspective with regard to plausibility and recognizable assignment to the tested product. The manufacturer is solely responsible for the accuracy, completeness, and timeliness of these documents. Further information on classification can be found in our article “Food Warnings, Product Tests and Consumer Protection”.
- Transparent declaration of ingredients and dosage
- Nicotinamide riboside content tested by an external laboratory
- Externally laboratory-tested for heavy metals and other residue groups
- One capsule per day – simple intake logic
- Multilingual peel-off label with high information density
- Double tamper-evident protection
- Light-protected container


- 30-capsule container appears approximately half full
- Batch number and best-before date print is not very abrasion-resistant
For dietary supplements, transparency is particularly important. Consumers want to be able to understand which ingredients are included, whether the dosage is clearly stated, and whether the product arrives protected and undamaged. In the test, NULLURE Nicotinamide Riboside made a solid impression precisely in these areas.
The packaging is functionally implemented and showed no relevant defects during the test. The containers appeared cleanly finished, stable, and plausibly protected from light. Before first use, the product was secured in two ways: by the safety ring on the lid and by an additional protective seal under the closure. This would make any previous opening clearly recognizable.
The capsules themselves were also unobtrusive in a positive sense. They were dry, not stuck together, undamaged, and could be removed individually without difficulty. The application is clearly understandable: one capsule per day forms the recommended daily dose. Each capsule is stated to contain 663 mg of capsule content. This makes the variants with 30, 60, and 90 capsules easy to classify, with each being designed for 30, 60, or 90 days respectively.
The declaration is transparent. The label lists nicotinamide riboside chloride, potato starch, and a plant-based capsule with an HPMC coating as ingredients. The product is labelled as vegan and GMO-free. The intake instructions are also clear: one capsule daily with sufficient water, preferably on an empty stomach. Warning and storage instructions are provided, including information not to exceed the daily dose, to keep the product out of reach of small children, and to store it in a cool, dry place away from direct sunlight.
External laboratory documents were also available. The AGROLAB report states 340 mg of nicotinamide riboside per capsule for the tested sample, with a target content of 300 mg per capsule. The report also includes, among other things, heavy metals and microbiological parameters; in addition, a Clean Label certificate from Ellipse Analytics was provided for the product. For consumers who value traceably documented supplementary intake of nicotinamide riboside chloride, this provides a solid basis for classification.
Minor limitations mainly concern the presentation and individual packaging details. The 30-capsule variant uses the same container as the 60-capsule variant and therefore appears approximately half full when opened. In addition, the text on the smaller labels is not always comfortably readable due to the high information density. The subsequently applied print showing the batch number and best-before date proved to be not very abrasion-resistant when rubbed with the fingers. When deliberately smelling inside the opened container, a slightly sour inherent odour was also noticeable, although this was not significant during normal handling of individual capsules.
Note on classification: At Deutsches Test Institut (DTI), products are assessed holistically from a consumer perspective. For foods and dietary supplements, the performance of the test requires the manufacturer to provide corresponding external laboratory analyses. DTI does not conduct its own laboratory analyses. The health effect of nicotinamide riboside was also not assessed as part of the test.
