Why Use NAD+ with Quercetin & Japanese Knotweed?
Modern life drains your cellular batteries. This formula pairs NAD+ precursors with powerful polyphenols like quercetin and Japanese knotweed (resveratrol source) to help support energy, healthy inflammation balance, and long-term vitality.
Cellular Energy & Mitochondria
NAD+ is a cofactor used in hundreds of cellular reactions related to energy production. Supporting NAD+ levels helps your cells make and use energy more efficiently so you feel it in your day-to-day life.
Healthy Aging From the Inside Out
Polyphenols like quercetin and resveratrol-rich Japanese knotweed have been studied for their role in supporting healthy aging pathways, including cellular stress response and antioxidant defenses.
Support for Inflammation Balance
Quercetin helps support a balanced inflammatory response, which is essential for joint comfort, cardiovascular health, and long-term resilience.
Stacks Easily With Your Routine
Designed to complement time-restricted eating, exercise, and a nutrient-dense diet — not replace them. Take it daily or as part of a cyclical NAD+ protocol.
In One Serving of NAD+ with Quercetin & Japanese Knotweed

As a biohacker, I was skeptical because I'm used to paying an arm and a leg for supplements. But the quality is legit — these are premium formulas† at wholesale prices. The membership pays for itself in my first order every month.
