What Is Tru Niagen Pro?
Tru Niagen Pro represents the pinnacle of NAD+ supplementation technology, delivering 1,000mg of clinically-proven nicotinamide riboside (NR) per serving. As a pharmacist who has extensively reviewed NAD+ precursor supplements, I can confirm that this formulation stands among the most potent and scientifically-validated options available.
Expert Insight: NAD+ (nicotinamide adenine dinucleotide) serves as a critical coenzyme in over 400 enzymatic reactions within our cells. Research published in Biochemical Pharmacology demonstrates that NAD+ depletion is a hallmark of aging, making supplementation increasingly important for maintaining cellular health.
The Science Behind NAD+ Decline
According to research from Harvard Medical School, NAD+ levels decline significantly with age due to:
- Decreased biosynthesis of NAD+ precursors
- Increased consumption by CD38 and other NAD+-consuming enzymes
- Reduced efficiency of salvage pathways
- Mitochondrial dysfunction affecting NAD+ regeneration

Clinical Benefits of Tru Niagen Pro
Human studies suggest that supplementation with Nicotinamide Riboside (NR) may support healthy aging and offer protection against certain age-related conditions. While promising, NR is not a substitute for maintaining a balanced diet, regular exercise, and a healthy lifestyle. Below are some of the potential benefits of taking NR supplements such as Tru Niagen:.🔋 Enhanced Cellular Energy
Clinical studies show NAD+ supplementation improves mitochondrial function by up to 40%, leading to sustained energy levels throughout the day.
🧬 DNA Repair Support
NAD+ activates sirtuins and PARP enzymes crucial for DNA repair mechanisms, potentially slowing cellular aging processes.
💪 Athletic Recovery
Research indicates faster muscle recovery and improved exercise performance through enhanced cellular repair mechanisms.
🧠 Cognitive Support
Recent research suggest that NR increase NAD+ level which supports neuronal health and may improve focus, mental clarity, and overall cognitive function.
❤️ Cardiovascular Health
Studies suggest NAD+ supplementation may support healthy blood flow and cardiovascular function.
⏰ Healthy Aging
By supporting cellular repair and energy production, NAD+ may help maintain vitality as we age.
Clinical Evidence Summary
A 2021 randomized controlled trial published in Nature Metabolism demonstrated that 1,000mg daily NR supplementation for 21 days resulted in:
- 142% increase in NAD+ levels
- Improved insulin sensitivity
- Enhanced mitochondrial biogenesis markers
- No significant adverse effects reported
Dosage and Administration Guidelines
Recommended Dosage
Standard Dose: Two 500mg capsules daily (total: 1,000mg)

Frequently Asked Questions
Tru Niagen Pro is an over-the-counter (OTC) dietary supplement. It does not require a prescription and is available for purchase online and in select retail stores. However, consulting with a healthcare provider before starting any new supplement regimen is always recommended.
Yes, clinical studies have demonstrated that 1,000mg daily is safe for most healthy adults. Research trials lasting up to 12 weeks at this dose showed no significant adverse effects. The FDA has granted GRAS status to nicotinamide riboside, further supporting its safety profile.
Taking more than 1,000mg daily is not recommended and has not been proven to provide additional benefits. Higher doses may increase the risk of mild side effects such as gastrointestinal discomfort. Stick to the recommended dosage for optimal safety and efficacy.
NAD+ levels begin rising within 24-48 hours of taking Tru Niagen Pro. Significant increases (40-150%) are typically observed after 2 weeks of consistent daily use. Peak benefits for energy, recovery, and cellular repair become more apparent with continued use over 2-3 months.
Yes, by elevating NAD+ levels, Tru Niagen Pro enhances mitochondrial function and cellular repair processes. Clinical studies show improved energy metabolism, and many users report increased vitality, better exercise recovery, and improved mental clarity within 2-4 weeks of consistent use.
Absolutely. Mitochondria rely heavily on NAD+ for energy production through the electron transport chain. Research shows that NAD+ supplementation can improve mitochondrial biogenesis, enhance respiratory function, and support overall mitochondrial health, leading to better cellular energy production.
Inflammation: NAD+ activates sirtuins, which help regulate inflammatory responses. While research is promising, more human studies are needed for definitive conclusions. Cognitive Function: Early clinical data and user reports suggest benefits in focus and mental clarity, likely due to improved neuronal energy metabolism and neuroprotective effects.
500mg daily: Suitable for maintenance and those new to NAD+ supplementation, provides moderate NAD+ elevation (40-80%). 1,000mg daily: Designed for maximum NAD+ support (up to 150% increase), ideal for individuals seeking intensive cellular support, athletes, or those focused on healthy aging.
Active Ingredients and Mechanism of Action
Primary Active Ingredient
Nicotinamide Riboside (NR) – 1,000mg per serving
Nicotinamide riboside is a patented form of Vitamin B3 that serves as a direct precursor to NAD+. Unlike other NAD+ precursors, NR bypasses rate-limiting enzymes, making it highly efficient for NAD+ biosynthesis.
Mechanism of Action
| Step | Process | Outcome | Time Frame |
|---|---|---|---|
| 1 | NR absorption in small intestine | Rapid uptake into bloodstream | 30-60 minutes |
| 2 | Cellular uptake via ENT1 transporters | NR enters cells efficiently | 1-2 hours |
| 3 | Conversion by NRK1/NRK2 enzymes | NMN (nicotinamide mononucleotide) formation | 2-4 hours |
| 4 | NMNAT enzymes convert NMN to NAD+ | Active NAD+ available for cellular processes | 4-8 hours |
