Description

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell, involved in normal cellular energy metabolism.* NAD levels naturally decline with age. This doesn't mean NAD+ supplements treat or prevent age-related disease, but it's part of why NAD+ and its precursor nutrients have become an area of ongoing research interest.

Double Wood's NAD+ Supplement provides 500mg of NAD+ per serving, verified at greater than 95% purity, as the single active ingredient, not a precursor relabeled as NAD+, and not a small amount diluted inside a larger blend. We state the number plainly so you can compare labels honestly.

It's worth being transparent about where the current science stands: the strongest human clinical evidence in this category exists for precursor compounds like NMN and NR, which have been evaluated in more randomized human trials to date. Direct oral NAD+ supplementation, the approach this product uses, has less clinical trial data available so far.

Compare this formula with NMN, NMNH, or NR Malate to find the option that best fits your routine.

Soy-Free, Gluten-Free, Non-GMO, Vegan. Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly.

Benefits

  • Real, single-ingredient NAD+. Each serving delivers 500mg of NAD+ at 95% purity as the sole active ingredient, not diluted inside a larger blend.*
  • Supports NAD levels already within the normal range as part of a healthy lifestyle.*
  • NAD+ directly, not a precursor. NMN and NR are precursor nutrients the body converts into NAD+. This product provides NAD+ itself, a different approach than precursor-based products.
  • Currently, the strongest human clinical evidence in this category exists for precursor compounds. We think that's worth knowing so you can choose with accurate expectations.
  • Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly.

Directions & Dosage

Take 2 capsules (500mg) daily on an empty stomach, preferably in the morning. Do not exceed the recommended serving unless directed by a healthcare professional.

Supplement Facts

NAD+ vs. NMN vs. NMNH vs. NR Malate - which one is right for you?

If you're new to NAD+ supplementation, the question isn't whether to support your NAD+ levels - it's where in the pathway to start. Each one enters the salvage pathway at a different point, has a different evidence base, and suits a different type of user. Here's how they compare.

Still not sure? A reasonable rule of thumb: if you want the deepest published evidence base, start with NR Malate. If you want the most-discussed direct precursor in longevity protocols, start with NMN. If you want the newest NMN form with promising preclinical data, NMNH is the early-adopter pick.

Frequently Asked Questions

What is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a vital coenzyme found in every cell of the body, playing a critical role in energy production and cellular repair. It supports metabolism, DNA repair, and healthy aging processes.

Why do NAD+ levels matter as we age?

NAD+ plays a central role in redox reactions, mitochondrial function, cellular energy metabolism, DNA repair pathways, and NAD+-dependent enzymes such as sirtuins and PARPs. Research reviews have reported that NAD+ metabolism changes with age and may influence cellular processes connected to healthy aging. This does not mean NAD+ supplements treat or prevent age-related disease, but it explains why NAD+ support has become a major area of longevity research.

How much NAD+ should I take per day?

The recommended daily serving is 2 capsules per day, which provides 500 mg of NAD+. Take it on an empty stomach, preferably in the morning, and do not exceed the recommended dosage unless directed by a healthcare professional.

Taking NAD+ in the morning aligns with when many people prefer to support energy metabolism, while taking it on an empty stomach may help reduce competition with food during digestion. Some people choose to split their serving between morning and early afternoon, but the product’s standard serving is 2 capsules daily.

What’s the difference between NAD, NAD+, NMN, NR, and NMNH?

NAD+ is the active oxidized form of nicotinamide adenine dinucleotide, a coenzyme involved in cellular energy metabolism. NAD is often used as a general shorthand for the NAD family. NMN, NR, and NMNH are precursor nutrients or related compounds that the body can use in NAD+ metabolism. Double Wood’s NAD+ Supplement provides direct NAD+, while NMN, NMNH, and NR Malate are different options for people who prefer precursor-based NAD+ support.

What are the side effects of NAD+ supplements?

NAD+ supplements are generally well-tolerated, but some individuals may experience mild side effects such as nausea, headaches, fatigue, or digestive discomfort. Always consult a healthcare provider if side effects persist or worsen.

Excellent Quality

"Quality product, good packaging, consistent product, long term daily maintenance."

— Aaron K. (5/5)

I rarely see obvious benefits right away. . .

"As a chemist and biologist, I am intrigued by the theoretical benefits of many supplements but typically find that I can see no real changes -- short term or long term. Of course, if longevity is the long-term goal, I suppose we have to wait for the review from the afterlife, but these seem to provide me with more energy to complete more tasks in my hectic 365-day work year."

— Stephen G. (5/5)

Doing well
