What is nicotinamide riboside?

Nicotinamide riboside (NR) is a form of vitamin B3 and a direct precursor of NAD⁺, the central coenzyme of your cellular energy. This coenzyme drives the reactions that your cells use to generate energy, and its level decreases with age. Your cells produce new NAD⁺ directly from NR. As a form of B3, it also fulfils a recognized function: contributing to normal energy metabolism.

Pure nicotinamide riboside in every capsule

Each capsule contains pure nicotinamide riboside chloride in the full dose of 300 mg, which is also used in clinical studies. No more than this one active ingredient is needed: no fillers, a vegan HPMC capsule, manufactured according to GMP and IFS standards. You can find the exact amount of niacin and the NRV value in the nutritional value table.

Intake & routine: 1 capsule daily

Take one capsule daily, in the morning, unchewed with plenty of liquid. No protocol, no extra effort. Nicotinamide Riboside is designed for daily, long-term use, not for a quick effect. Clinical studies show that it takes around two weeks for the NAD⁺ level in the blood to change. Give the active ingredient a few weeks, then you will have an honest assessment.

Well tolerated: no skin tingling, no reddening of the skin

Nicotinamide riboside is the skin-friendly B3 form. Unlike classic niacin in higher doses, it generally does not cause a warm, tingling face. NR300 uses this well-tolerated form, so you swallow your capsule in the morning and get straight on with your day. No stomach burn, tasteless, day after day.

NR300 at a glance

NR300 brings three things together in one capsule: the vegan NAD⁺ precursor made from pure nicotinamide riboside, the recognized contribution of niacin to energy metabolism and a single active ingredient with no fillers.

NR300 is the vegan daily capsule with pure NR, made in Germany. Order now directly from Gigas Nutrition.

Frequently asked questions about NR300 Nicotinamide Riboside

How much nicotinamide riboside is in one capsule?
One capsule provides 300 mg NR, which corresponds to around 130 mg niacin. The BfR guideline value for nicotinamide is 160 mg per day, so the amount consumed remains within safe limits. Do not exceed the recommended intake.

Does NR cause a flush like classic niacin?
NR is a different form of vitamin B3 than nicotinic acid and is metabolized differently in the body. For you, this means: as a rule, no skin tingling and no reddening of the skin, even when taken daily over several weeks.

Is this product vegan?
Yes, the capsule shell consists of vegetable HPMC, animal ingredients are not included.

Is this product available as a capsule or as a powder?
As a practical capsule, not as a powder. This saves you weighing, is tasteless and gives you exactly the same amount every day. Simply take with water and you're done.
