NAD+, Quercetin & Resveratrol: The Trio Behind Cellular Energy and Healthy Aging

Every cell in your body runs on energy, and behind that energy is a molecule most people have never thought about: NAD+. It quietly powers hundreds of processes that keep you feeling sharp, energized, and resilient — until, with age, its levels begin to slip. That's exactly the gap our NAD+ formula was built to address, and it does so with more than NAD+ alone.

At Moda Gross Health, we paired NAD+ with two of the most researched plant compounds in the longevity world — Quercetin and Resveratrol — to create a single daily capsule designed to support energy, metabolic health, and cellular resilience. Here's the science behind why this combination makes sense.

What Is NAD+?

NAD+ stands for Nicotinamide Adenine Dinucleotide, a coenzyme found in every living cell. Think of it as the spark plug of your cellular engine. It helps convert the food you eat into usable energy, supports DNA repair, and drives the metabolic reactions that keep your cells functioning properly.

Without adequate NAD+, cells simply can't produce energy efficiently. This is why NAD+ has become one of the most studied molecules in the science of aging and vitality.

Why NAD+ Declines With Age

Here's the part that gets researchers' attention: NAD+ levels don't stay constant throughout life. Studies suggest that NAD+ concentrations in tissues like muscle, skin, and the brain decline significantly as we get older.

This natural decline is thought to be one factor behind reduced energy metabolism and slower cellular repair over time. Habits like regular exercise and a balanced diet help, but for many adults, supporting NAD+ directly has become an appealing, proactive addition to a healthy lifestyle.

Why We Added Quercetin and Resveratrol

NAD+ on its own is powerful — but it doesn't work in isolation inside your body. That's why our formula pairs it with two complementary, plant-based compounds:

Quercetin is a natural flavonoid found in foods like onions, apples, and capers. In our formula it's sourced from Sophora japonica flower buds. Quercetin is valued for helping promote a normal inflammatory response and supporting healthy immune function — both of which matter for cells trying to stay resilient over time.

Resveratrol is a polyphenol most famously associated with red wine, though ours is sourced from Japanese Knotweed (Polygonum cuspidatum) at 98% purity. Resveratrol has been studied for its role in supporting cardiovascular health and helping maintain cognitive wellness. It's often discussed alongside NAD+ in longevity research because the two are thought to complement each other in supporting cellular pathways.

Together, this trio is designed to do more than boost a single marker — it's built to support the broader ecosystem of energy production, cellular defense, and overall well-being.

What Makes Our NAD+ Formula Different

A supplement is only as good as what's inside it, and this one is formulated to deliver a meaningful, research-relevant dose of each ingredient. Here's what you get per serving (two capsules):

• NAD+ (Nicotinamide Adenine Dinucleotide) — 500 mg
• Quercetin Dihydrate (from Sophora japonica) — 250 mg
• Japanese Knotweed Extract (98% Resveratrol) — 150 mg

That's a 900 mg active blend in every serving, delivered in a plant-based (HPMC) vegetable capsule and made in the USA. Each bottle contains 60 capsules (50 g) — a full 30-day supply for a consistent daily routine.

No unnecessary fillers, no shortcuts — just a clean, thoughtfully balanced formula built around ingredients with real research behind them.

How to Add It to Your Routine

This supplement is simple to work into your day. As a dietary supplement, adults take two (2) capsules daily, ideally with about 6 oz (177 ml) of water, or as directed by a healthcare professional.

Consistency is where the real value lies. NAD+ support is about long-term cellular health, not an overnight fix — so it pairs naturally with the habits that also support your body: staying active, eating whole foods, managing stress, and getting quality sleep.

The Bottom Line

NAD+ sits at the heart of how your cells create energy, and it's one of the most exciting areas in modern wellness science. By combining NAD+ with Quercetin and Resveratrol, our formula takes a fuller, more holistic approach — supporting energy, metabolic health, cognitive wellness, and cellular resilience in a single daily capsule.

For adults who want to age with vitality and take a proactive, research-informed approach to their health, it's a clean and convenient place to start.

As a dietary supplement, adults take two capsules daily. Do not exceed the recommended dose. Pregnant or nursing mothers, children under 18, and individuals with known medical conditions should consult a physician before use. Keep out of reach of children.
