Doctor B NAD+ Supplement 500mg – Liposomal NAD+ 60 Capsules
The high-absorption NAD+ formula 12,000+ people use to restore cellular energy, sharpen focus, and feel a decade younger — built on the molecule behind 3 Nobel Prizes.
Built into the lives of those who feel it
From morning coffee to mountain mornings — Doctor B fits the way you actually live. These are the people who made it part of their day.
Built for the way modern life drains you
NAD+ powers every cell in your body. As it declines with age, so does your energy, focus, and recovery. Doctor B brings it back.
The molecule that science can't stop studying
NAD+ — the active compound in Doctor B — has been at the center of three Nobel Prizes since 1929 and remains the most-studied longevity target in modern medicine. Here's the lineage your two daily capsules connect to.
The shift that shows up in the mirror
NAD+ doesn't just feel different inside — it shows on your skin, in your eyes, in your posture. These are real customers, photographed at day 1 and day 90 of consistent Doctor B use.

By age 50, you've lost half your NAD+.
NAD+ (nicotinamide adenine dinucleotide) is the molecule your cells use to produce energy and repair themselves. Studies show NAD+ levels drop steadily after age 30 — and by 50, most people have less than half of what they had in their twenties.
That decline is why energy fades, focus slips, and recovery takes longer. Doctor B's liposomal delivery rebuilds those levels — fast and effectively.
"I built Doctor B because I refused to lose another decade to fading energy. So I made the formula I wanted to take myself."
After 30 years of clinical research into cellular aging, I kept running into the same wall — the NAD+ supplements on the market simply weren't getting absorbed. Most pills lose 80%+ of their potency in stomach acid before reaching the bloodstream.
So we developed a liposomal delivery system that protects the NAD+ molecule until it reaches your cells. We tested every batch in independent labs. We refused to compromise on dose. And we priced it for the long haul, because this is meant to be a daily habit — not a luxury splurge.
Every bottle that ships from us is one I'd give to my own family. That's the bar.
Not all NAD+ supplements are equal
Most NAD+ pills on the market break down before they even reach your bloodstream. Here's what sets us apart.
Three steps to cellular reset
Take it once. Feel it within weeks. Stay consistent for compounding results.
Take 2 capsules
In the morning with water — with or without food. Two capsules deliver a full 500mg NAD+ dose.
Liposomal delivery kicks in
Phospholipid bubbles shield the NAD+ molecule from stomach acid and shuttle it directly into your bloodstream — intact.
Cells recharge
NAD+ enters your cells and powers mitochondria, sirtuins, and DNA repair. You feel it within 2–4 weeks.

Pick the supply that fits your goals
Buy more, save more — and never run out. Most customers choose the 3-pack to give NAD+ time to compound.
Questions, answered
Most customers report noticeable improvements in energy and focus within 2–4 weeks of consistent daily use. Cellular benefits build over time — for the full effect, we recommend a minimum 3-month protocol.
Yes. Standard NAD+ capsules suffer from poor bioavailability — most of the molecule breaks down in stomach acid before reaching your cells. Our liposomal delivery wraps NAD+ in phospholipid bubbles that protect it through digestion, resulting in up to 6× higher absorption.
NMN and NR are precursors — your body still has to convert them into NAD+. Doctor B delivers the NAD+ molecule directly, so your cells don't need to do the conversion work. It's a more efficient path, especially as you age and conversion enzymes decline.
NAD+ is generally well-tolerated. A small percentage of users report mild flushing or nausea when starting — this typically resolves within a week. We recommend starting with 1 capsule for the first 3 days and ramping up to the full 2-capsule dose.
Doctor B pairs well with most supplement stacks (resveratrol, CoQ10, magnesium, vitamin D). If you're on prescription medication or have a medical condition, please consult your healthcare provider before starting any new supplement.
We offer a 60-day, 100% money-back guarantee. Try Doctor B for two full months — if you don't feel a meaningful difference, email us and we'll refund every penny. Even if the bottles are empty.
You save 15% on every order, get free shipping, and we deliver a fresh bottle every 30 days. No commitment — pause, skip, or cancel anytime from your account.
Doctor B is manufactured in the United States in an FDA-registered, GMP-certified facility. Every batch is third-party tested for purity, potency, and contaminants — Certificates of Analysis available on request.
