Nicotinamide Riboside (NRC) - 300 mg NAD⁺ Precursor | 90 Capsules

What is nicotinamide riboside? The NAD⁺ precursor from the vitamin B3 family

  • Nicotinamide riboside (NR) is a form of vitamin B3 (niacin) from the class of pyridine nucleosides; in food supplements it is used as the stable salt nicotinamide riboside chloride (NRC).
  • In the body, nicotinamide riboside serves as a precursor of NAD⁺ (nicotinamide adenine dinucleotide), a coenzyme involved in numerous metabolic reactions in the cell.
  • Nicotinamide riboside was originally described as a nutrient in milk and has been authorised in the EU as a novel food for food supplements since 2020 (Implementing Regulation (EU) 2020/16).

NAD⁺ precursor with 300 mg NRC - study-based and EU-compliant dosage

  • Green Naturals NRC contains 300 mg nicotinamide riboside chloride per daily dose - the highest amount the EU permits for adults - compared to many manufacturers who dose significantly lower or disregard novel food limits.
  • The daily dose is clearly declared: 300 mg NRC with 126 mg niacin equivalent - compared to many "NAD⁺ boosters" that hide active ingredient amounts in blends.
  • Exactly this amount of 300 mg per day was investigated in a randomised, double-blind, placebo-controlled 8-week study with 140 adults (Conze et al., 2019); the oral bioavailability of nicotinamide riboside in humans had previously been shown (Trammell et al., 2016).

With niacin (vitamin B3) - proven benefit according to EFSA

  • Niacin contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function and the reduction of tiredness and fatigue (authorised EFSA claims).
  • Each capsule provides 126 mg niacin equivalent (NE) - corresponding to 787.5% of the nutrient reference value (NRV).
  • 90 vegan capsules last 90 days at 1 capsule daily - 3 months' supply in one jar.

What is NAD⁺?

NAD⁺ (nicotinamide adenine dinucleotide) is a coenzyme found in all body cells and involved in numerous metabolic reactions, for example in obtaining energy from nutrients. The body forms NAD⁺ from precursors such as niacin, nicotinamide or nicotinamide riboside. NAD⁺ itself is being intensively researched, but there are no authorised health claims for NAD⁺.

What is nicotinamide riboside?

Nicotinamide riboside (NR) is a form of vitamin B3 and a precursor of NAD⁺. In food supplements it is used as nicotinamide riboside chloride (NRC), which is more stable than the pure compound. NRC has been authorised in the EU as a novel food since 2020. Green Naturals NRC contains 300 mg per capsule with 126 mg niacin.

What does NAD⁺ do?

As a coenzyme, NAD⁺ is involved in reactions of energy metabolism in cells and is being investigated in studies on ageing processes. There are no authorised health claims for NAD⁺ or nicotinamide riboside itself. However, the niacin contained in NRC contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue.

How does nicotinamide riboside work?

Nicotinamide riboside is converted into NAD⁺ in the body; a human study showed that orally ingested NR increases NAD⁺ metabolism in the blood (Trammell et al., 2016). 300 mg per day was also investigated in a placebo-controlled study over 8 weeks (Conze et al., 2019). There are no authorised health claims for NR, but there are for the niacin it contains, which contributes to normal psychological function and normal functioning of the nervous system.

What is the difference between NMN and NR?

NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are both precursors of NAD⁺; NR is the smaller compound without a phosphate group. An important difference is the legal situation: nicotinamide riboside chloride has been authorised in the EU as a novel food for food supplements since 2020 and is therefore well established. That is why Green Naturals relies on NRC at the authorised daily dose of 300 mg.

Is nicotinamide riboside authorised in the EU?

Yes. Nicotinamide riboside chloride has been authorised as a novel food since 2020 by Implementing Regulation (EU) 2020/16, following EFSA's safety assessment (EFSA, 2019). For adults, a maximum of 300 mg per day has been set for food supplements. Green Naturals NRC provides exactly this amount with 1 capsule daily.

What is the dosage of NRC?

The daily dose is 1 capsule with 300 mg nicotinamide riboside chloride; this corresponds to 126 mg niacin equivalent and 787.5% of the nutrient reference value. Take the capsule with sufficient liquid during a meal. Do not exceed the recommended daily intake.

When should you take NRC?

We recommend taking it in the morning or at lunchtime with a meal and sufficient liquid. This makes the capsule easy to integrate into your daily routine. The time of day matters less than regular daily intake over a longer period.

Can the capsules be opened?

Yes. The vegan HPMC capsule can be opened and the contents stirred into water, juice or yoghurt, for example. Take the entire contents immediately after opening. However, the easiest way is to take the whole capsule with sufficient liquid during a meal.

Is the product completely natural?

The formulation is deliberately minimal: nicotinamide riboside chloride, rice starch as a natural carrier and a plant-based capsule shell made of hydroxypropyl methylcellulose. We completely avoid artificial colours, preservatives and flavourings. NRC itself is a nature-identical nutrient that also occurs in small amounts in milk and is produced in pure form for food supplements.

Who is NRC not suitable for?

The product is intended for adults only and is not recommended for pregnant or breastfeeding women. Keep out of the reach of young children. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. If you have questions about intake, please consult your doctor or pharmacist.

How long does a jar last?

One jar contains 90 capsules. At 1 capsule daily, it lasts 90 days, i.e. around 3 months. Store the jar in a cool, dry place protected from light.

Is NRC available in pharmacies?

In Germany, Green Naturals® Nicotinamide Riboside Chloride can be ordered from your online or local pharmacy using PZN 20862382 (a German pharmacy code). Outside Germany, you can buy the capsules directly from the Green Naturals online shop or via online pharmacies. NRC is a food supplement and does not require a pharmacy.
