500mg NAD+ with Quercetin and Resveratrol. Supports cellular energy production, healthy aging, cognitive function, and natural repair processes.
We selected this formula because NAD+ alone is only part of the story — and most products stop there. NAD+ declines naturally with age, and supplementing it supports the cellular energy pathways that underpin everything from mental clarity to physical recovery. What makes this formula stand out is the supporting cast: Quercetin (250mg from Sophora japonica) for its well-researched anti-inflammatory and immune effects, and Resveratrol (150mg at 98% potency from Japanese Knotweed root) for cardiovascular and cognitive support. The 500mg NAD+ dose is within the range used in clinical research, the capsule is vegetarian (HPMC), it's allergen-free and 100% natural, and it met our quality standards for sourcing and third-party testing.
Description
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell in the body — central to how cells produce energy, repair DNA, and maintain function over time. Levels decline naturally with age, which is why supplementing it has become one of the more research-backed approaches to healthy aging and sustained vitality.
This formula pairs 500mg of NAD+ with two well-studied plant compounds — Quercetin for immune and inflammatory support, and Resveratrol for heart and brain health. Two capsules daily. Vegetarian. Allergen-free. A serious formula for people who take their longevity routine seriously.
What This Supports
Cellular Energy
NAD+ is central to how cells produce ATP — the body's energy currency. Supporting NAD+ levels helps maintain natural vitality and metabolic function.
Cognitive Function
NAD+ supports neurological energy production. Resveratrol adds further brain health support through its cardiovascular and neuroprotective research profile.
Healthy Aging
NAD+ supports normal DNA repair processes and cellular regeneration — both of which slow with age when NAD+ levels decline.
Immune & Inflammation
Quercetin (250mg) is a well-studied flavonoid that supports a balanced inflammatory response and healthy immune function.
How Each Ingredient Works
- NAD+ 500mg: Powers cellular energy production via the mitochondria. Supports DNA repair, metabolic function, and declines naturally after age 30 — making supplementation increasingly relevant with age.
- Quercetin 250mg (Sophora japonica flower bud): A natural flavonoid with one of the strongest research profiles for anti-inflammatory and immune support. The Sophora japonica source is a high-potency botanical form.
- Resveratrol 150mg at 98% (Japanese Knotweed root): A polyphenol studied for cardiovascular protection and cognitive support. Japanese Knotweed root provides one of the most concentrated natural sources of resveratrol available.
How to Use
Suggested Use: Take two capsules daily with 6oz (177ml) of water, or as directed by a healthcare professional.
- Take in the morning to support energy and focus throughout the day
- Consistent daily use is key — NAD+ support builds over time
- Can be taken with or without food
- Do not exceed the recommended dose
