Frequently Asked Questions
What is an NR supplement? Nicotinamide Riboside (NR) is a form of vitamin B3 that acts as a direct precursor to NAD+, a coenzyme essential for cellular energy production, DNA repair, and overall vitality. NR supplements help restore declining NAD+ levels that occur with aging.
How does NR boost NAD+ levels? Once ingested, NR is converted into nicotinamide mononucleotide (NMN) and then into NAD+ through a series of enzymatic reactions. This process bypasses some rate-limiting steps, making NR an efficient way to raise NAD+ compared to other precursors like niacin.
Which NR supplement is best for me? Your choice depends on your priorities. For pure NR with high potency and clean ingredients, the partiQlar NR Supplement is a top pick. If you prefer a formula with resveratrol and quercetin for added antioxidant benefits, consider Life Extension or Pure Encapsulations.
