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

Tru Niagen Pro 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]*
