Origin & History
Natural habitat
Tru Niagen contains Nicotinamide Riboside, a form of vitamin B3 found in trace amounts in milk and yeast. It is synthesized through a proprietary process to enhance bioavailability.
“Nicotinamide Riboside is a relatively recent discovery in the context of vitamin B3 research, with growing interest in its potential for promoting healthy aging.”Traditional Medicine
Scientific Research
Numerous studies, including human trials, have shown that Nicotinamide Riboside effectively increases NAD+ levels, supporting metabolic and cellular health.
Preparation & Dosage
Traditional preparation
Recommended dosage is 300 mg per day. Consult a healthcare provider before use.
Nutritional Profile
Tru Niagen contains Nicotinamide Riboside (NR) chloride as its sole active ingredient, typically dosed at 300 mg per capsule (standard recommended daily dose). NR is a form of vitamin B3 (niacin) and a direct precursor to nicotinamide adenine dinucleotide (NAD+). Molecular weight of NR chloride: ~290.7 g/mol. Each 300 mg dose provides approximately 255 mg of free nicotinamide riboside base. Unlike nicotinic acid (niacin), NR does not activate the GPR109A receptor, meaning it does not cause flushing. Bioavailability: Oral NR is efficiently absorbed in the gut and converted to NAD+ primarily via the nicotinamide riboside kinase (NRK1/NRK2) pathway. Human pharmacokinetic studies demonstrate that 300 mg/day NR can increase whole blood NAD+ levels by approximately 40–90% within 2–4 weeks. NR is more bioavailable as an NAD+ precursor compared to nicotinamide (NAM) and nicotinic acid (NA) due to its direct phosphorylation to nicotinamide mononucleotide (NMN) bypassing rate-limiting steps in the salvage pathway. Contains no significant macronutrients (negligible calories, no protein, fat, carbohydrates, or fiber). Inactive ingredients typically include microcrystalline cellulose, hypromellose (vegetarian capsule), and vegetable magnesium stearate. No vitamins or minerals beyond the B3-related activity of NR itself. The product is patented as NIAGEN® (ChromaDex's proprietary NR chloride), with identity and purity verified via third-party testing. Does not contain caffeine, stimulants, sugars, gluten, nuts, or artificial colors. Peak plasma NR metabolite levels occur approximately 1–3 hours post-ingestion. NR is water-soluble; excess is metabolized and excreted renally, primarily as methylated nicotinamide metabolites (e.g., N-methyl-2-pyridone-5-carboxamide and N-methyl-nicotinamide).
How It Works
Mechanism of Action
Nicotinamide riboside is converted to NAD+ through the salvage pathway via nicotinamide riboside kinases (NRK1 and NRK2). Elevated NAD+ levels activate sirtuins (SIRT1-7), a family of deacetylase enzymes that regulate cellular stress responses, DNA repair, and mitochondrial biogenesis. This process also supports poly(ADP-ribose) polymerase (PARP) function, crucial for maintaining genomic stability.
Clinical Evidence
Human studies show nicotinamide riboside supplementation can increase NAD+ levels by 40-90% within 2-8 weeks. A randomized controlled trial of 140 adults found 300mg daily improved muscle NAD+ levels and insulin sensitivity. However, most longevity and cognitive benefits are primarily demonstrated in animal studies, with limited long-term human data on anti-aging effects.
Safety & Interactions
Nicotinamide riboside is generally well-tolerated with mild side effects including nausea, fatigue, and headaches at doses above 1000mg daily. No significant drug interactions have been reported, though it may theoretically interact with medications affecting NAD+ metabolism. Safety during pregnancy and breastfeeding has not been established. Individuals with liver disease should consult healthcare providers before use.

Frequently Asked Questions
How much Tru Niagen should I take daily?
Clinical studies typically use 250-300mg daily, though Tru Niagen capsules contain 300mg nicotinamide riboside chloride. Most research supports once-daily dosing, preferably with food to minimize gastrointestinal effects.
How long does it take for Tru Niagen to increase NAD+ levels?
NAD+ levels typically increase within 2-4 weeks of consistent supplementation. Peak levels are usually achieved by 8 weeks, with some studies showing 60-90% increases in cellular NAD+ concentrations.
Is Tru Niagen better than regular niacin for boosting NAD+?
Nicotinamide riboside bypasses the rate-limiting enzyme NAMPT in the NAD+ salvage pathway, potentially making it more efficient than niacin. Unlike niacin, it doesn't cause flushing or significantly affect blood lipid levels.
Can I take Tru Niagen with other longevity supplements?
Tru Niagen can generally be combined with resveratrol, pterostilbene, or metformin, as these compounds may work synergistically with increased NAD+ levels. However, consult a healthcare provider before combining multiple supplements.
Does Tru Niagen help with exercise performance and recovery?
Some studies suggest NAD+ enhancement may improve mitochondrial function and cellular energy production. However, specific exercise performance benefits from Tru Niagen supplementation require more research, with most evidence being preliminary or from animal studies.
What does the clinical research show about Tru Niagen's effects on aging and longevity?
Clinical studies demonstrate that Tru Niagen (nicotinamide riboside) effectively raises NAD+ levels in humans, with research linking increased NAD+ to improved mitochondrial function and cellular repair mechanisms. Multiple peer-reviewed trials have shown benefits for metabolic health, muscle function, and cardiovascular markers in both healthy adults and those with metabolic challenges. While human longevity studies are still ongoing, the mechanistic evidence strongly supports NAD+ boosting as a valid anti-aging strategy backed by rigorous scientific investigation.
Is Tru Niagen safe to take with common medications like blood pressure or diabetes drugs?
Tru Niagen has a favorable safety profile with minimal documented interactions with common medications, though individuals on blood thinners, antifungals, or certain statins should consult their healthcare provider. Nicotinamide riboside does not significantly inhibit or induce cytochrome P450 enzymes responsible for most drug metabolism, making it generally compatible with most pharmaceutical treatments. As with any supplement, it's best to inform your doctor or pharmacist before combining Tru Niagen with prescription medications to ensure no individual contraindications exist.
Who benefits most from taking Tru Niagen supplementation?
Tru Niagen is particularly beneficial for individuals over 40, those with sedentary lifestyles, and people experiencing age-related decline in energy, cognitive function, or metabolic health—populations where NAD+ naturally declines. Athletes and highly active individuals may also benefit from improved mitochondrial energy production and enhanced recovery between workouts. People concerned with healthy aging, cognitive maintenance, or those with metabolic conditions like prediabetes may see the most pronounced benefits, though it can support general wellness across most adult populations.
