What is NR?

Nicotinamide riboside (NR) is an innovative and bioavailable form of vitamin B3, which is efficiently converted in the body into NAD+ – an essential coenzyme necessary for energy production, cellular processes, and nutrient metabolism.

The level of NAD+ is naturally high in youth, but with increasing age and exposure to stress factors such as poor lifestyle or lack of sleep, it decreases.

This can affect cellular vitality and overall metabolism.

NR naturally occurs in small amounts in foods such as dairy products or yeast, but their consumption cannot ensure sufficient intake.

Therefore, the most effective way to supplement this substance is with a quality dietary supplement with a concentrated form of NR, which allows optimal absorption and utilization in the body.

How does NR work?

Nicotinamide riboside (NR) acts as a trigger of cellular energy in your body.

 

It converts into NAD+, a key molecule essential for energy production, cellular processes, and metabolism.

 

NAD+ levels naturally decrease with age, which can affect the efficiency of these processes.

 

Research suggests that supplementing NR may help maintain optimal NAD+ levels and thus support normal cell function.

 

This makes NR a popular supplement for those looking for ways to care for their cellular energy and vitality.

FAQ

Do NR capsules increase NAD+ levels without skin flushing and burning, and how can I tell in practice?

Yes. Unlike some forms of vitamin B3 (which can cause temporary skin flushing and heat), NR capsules are "flush-free" – they do not cause this redness or burning. In practice, the effect usually manifests gradually over 1–2 weeks of regular use (subjectively better daily energy, easier morning start). Direct laboratory verification of increased NAD+ requires specialized tests; in everyday practice, mainly monitor regularity and your own response.

How to time NR capsules in combination with TMG, apigenin, or GlyNAC?

We recommend taking NR capsules in the morning with breakfast. TMG can be taken simultaneously or in the morning, apigenin preferably in the evening. Divide GlyNAC (glycine + NAC) into 1–2 doses according to tolerance. Always drink with water, consult the regimen with a specialist for medications.

Is there a difference in the composition of NR capsules and NR powder, and why does the powder list small doses of B1 and zinc?

NR capsules specify the exact dose of NR per capsule and auxiliary ingredients (HPMC, possibly trace amounts of vitamin B1, zinc without quantification). For NR powder, the manufacturer also communicates micro-doses of B1 and zinc per scoop for precise powder dosing. It is a difference in technology and labeling, not a different type of active ingredient.

Where can I verify the purity and quality of NR capsules – do you have CoA and certifications?

CoA protocols (tests for heavy metals and mycotoxins) and manufacturing certifications (GMP, ISO 22000) are available for the product. Compare the batch number on the label with the documents; the declared purity > 98% is thus transparently documented.
