Our customer support operates from Monday to Friday, between 8:00 AM and 8:30 PM.
Nicotinamide Riboside (NR) is a precursor to NAD+, a vital coenzyme that supports cellular energy production, DNA repair, and metabolism. As we age, NAD+ levels decline, leading to fatigue, slower recovery, and cellular aging. NR helps restore and maintain optimal NAD+ levels, promoting longevity, vitality, and cognitive function.
LifespanMax NR is a premium, clinically-backed Nicotinamide Riboside supplement designed for maximum absorption and efficacy. Unlike some NAD+ supplements that use inferior precursors, we use pure NR, which has been scientifically studied for its ability to effectively convert into NAD+. Our formula is free from fillers, artificial additives, and unnecessary ingredients, ensuring a pure and potent supplement for optimal cellular health.
Most users begin to notice increased energy, improved focus, and better recovery within 2 to 4 weeks of consistent daily use. However, the full benefits, including cellular repair, longevity support, and metabolic optimization, continue to improve over time with long-term supplementation. Results may vary depending on age, lifestyle, and overall health.
Yes, NR is clinically tested and well-tolerated, even at higher doses. Studies show that NR supplementation is safe for long-term use, with no serious adverse effects reported. Some individuals may experience mild digestive discomfort when first starting NR, but this usually subsides as the body adjusts. As with any supplement, we recommend consulting with a healthcare professional if you have specific concerns.
Yes, NR is generally safe to take alongside other vitamins, minerals, and longevity supplements like Resveratrol, TMG (Trimethylglycine), or CoQ10. However, if you are on prescription medication or have underlying health conditions, it's always best to consult your doctor before adding NR to your routine.
