Take an active role in helping maintain your health, longer [1-3]. The key ingredient in TRU NIAGEN® is NIAGEN® nicotinamide riboside (NR)—a unique form of vitamin B3 clinically proven to increase nicotinamide adenine dinucleotide (NAD) [4-6], the critical catalyst that powers metabolism and helps maintain healthy cellular function.* 

NAD has been shown to decline with age [7, 8] and metabolic stress [9-12]. It has also been demonstrated to help support many aspects of healthy aging.

Tru Niagen provides daily cellular care to help you age better® and live better, including:
  
Replenishing NAD levels[4, 6, 13, 14]*
  
Increasing cellular energy production[14]*
  
Promoting healthy cellular metabolism[15-17]*
  
Promoting cellular repair[7, 15, 17, 18]*
  
Supporting healthy aging[4, 6, 13, 14]*
