What is Niagen and how does it raise NAD+ levels?+
Niagen is the brand name for Nicotinamide Riboside (NR), a form of Vitamin B3 that serves as a direct precursor to NAD+ (nicotinamide adenine dinucleotide). When you take Niagen orally, it is absorbed and converted to NMN, then to NAD+ via the cell's salvage pathway. Multiple clinical trials have shown that Niagen supplementation at 250–500 mg/day raises whole-blood NAD+ levels measurably within 2–4 weeks. NAD+ declines with age and drives many hallmarks of cellular aging.
What's the difference between Niagen (NR), NMN, and NAD+ IV therapy?+
NR (Niagen) and NMN are both oral NAD+ precursors that convert to NAD+ via slightly different pathways — NMN is one step closer to NAD+ but the clinical difference between them is debated. Both are effective oral options. NAD+ IV therapy is a fundamentally different delivery method — pure NAD+ administered directly into the bloodstream, bypassing gastrointestinal conversion. IV provides faster, more potent NAD+ elevation and is the most measurable approach. BHRC recommends combining oral Niagen for daily baseline support with periodic IV NAD+ for peak restoration.
How long does it take to notice results from Niagen?+
Clinical data shows measurable blood NAD+ increases within 2–4 weeks of daily Niagen supplementation at 250–500 mg. Subjective benefits — improved energy, better sleep, enhanced mental clarity, improved exercise recovery — are typically noticed by most patients within 4–8 weeks. Some patients, especially those with significant NAD+ deficiency or metabolic stress, report notable changes within 2 weeks. The most consistent results come from combining oral Niagen with periodic IV NAD+ sessions.
What are the documented benefits of raising NAD+ levels?+
Clinical research on NAD+ elevation (primarily through NR and NMN supplementation) has demonstrated: improved mitochondrial function and cellular energy production; activation of sirtuin enzymes (key regulators of aging and DNA repair); improved insulin sensitivity and metabolic health; reduced markers of systemic inflammation; improved muscle function and exercise recovery; enhanced cognitive function; and improved cardiovascular health markers. Long-term human clinical data is still accumulating, but the mechanistic evidence is compelling.
Is Niagen safe? Are there side effects?+
Niagen (NR) has been extensively studied and has an excellent safety profile at doses up to 1,000 mg/day. The most common side effects are minor GI symptoms (nausea, mild bloating) in some patients — these usually resolve by taking it with food or reducing the dose. There are no known serious adverse effects in healthy adults. NMN has a similarly clean safety profile based on available clinical data. BHRC providers review your complete health history and medications before recommending any supplement protocol.
How does BHRC differ from just buying Niagen online?+
Product quality, physician guidance, and protocol design. Supplement manufacturing standards vary enormously — many products on Amazon are underdosed, contaminated, or improperly stored. BHRC sources pharmaceutical-grade, third-party verified NR and NMN with documented potency. More importantly, BHRC builds an individualized protocol around your labs, health history, and goals — not a standard dose — and monitors your response over time. This is longevity medicine, not retail supplements.
Can I combine Niagen with NAD+ IV therapy?+
Yes — and BHRC recommends it. Oral Niagen provides daily baseline NAD+ support, maintaining cellular levels between treatments. IV NAD+ provides periodic peak restoration with immediate, high-bioavailability results. Combined, they address both the tonic (daily) and phasic (peak session) components of NAD+ optimization. BHRC builds this combined approach into its Longevity Stack protocol, with the ratio of oral to IV adjusted based on patient response and goals.
Who benefits most from Niagen supplementation?+
Niagen and NAD+ precursor protocols are most impactful for patients over 35 (when NAD+ decline accelerates), those with significant metabolic stress, high-performance professionals and athletes seeking cognitive and physical optimization, patients with fatigue or brain fog not explained by other conditions, and anyone pursuing a comprehensive longevity strategy. BHRC also uses Niagen as a foundational component of hormone optimization programs, where NAD+ decline intersects with hormonal aging.
