Frequently Asked Questions
Everything you need to know about NAD+ and our products.
What is NAD+ and why does it decline with age?
NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme found in every cell of your body. It plays a vital role in energy metabolism, DNA repair, and cellular signaling. NAD+ levels naturally decline with age due to increased consumption by enzymes like PARPs and CD38. By age 50, your NAD+ levels may be half of what they were in your 20s.
What is the difference between NMN and NR?
Both NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) are NAD+ precursors. NMN is one step closer to NAD+ and is converted directly, while NR must first be converted to NMN. NMN is generally considered the more direct and efficient precursor. Our NAD+ Complete formula includes both for comprehensive support.
How long before I notice results?
Most users report noticeable improvements in energy, mental clarity, and recovery within 2-4 weeks of consistent use. Optimal results typically appear after 8-12 weeks as NAD+ levels build up in tissues throughout the body.
Are Renue By Science products third-party tested?
Yes. Every single batch is independently tested by ISO-accredited third-party laboratories for purity, potency, heavy metals, and microbial contaminants. Certificates of Analysis are available upon request — we believe in complete transparency.
