Description

NMN (nicotinamide mononucleotide) is a naturally occurring nucleotide that serves as a precursor in the body's NAD+ (nicotinamide adenine dinucleotide) synthesis pathway. NAD+ is a coenzyme central to cellular energy metabolism, and its levels are known to decline with age, making precursor compounds like NMN an active area of published human research.* This formula delivers 250mg of NMN per serving, best taken earlier in the day as part of a consistent morning routine.

Manufactured in the USA in a cGMP-certified facility. Every batch is tested for purity, potency, heavy metals, and microbial safety. Third-party tests by ISO/IEC 17025-accredited labs. COAs published openly. NMN pairs naturally with Spermidine as part of a complete healthy aging routine.*

Frequently Asked Questions

When is the best time to take NMN?

The best time to take NMN (Nicotinamide Mononucleotide) is in the morning, as it aligns with the body's natural circadian rhythm and may support energy production throughout the day so you can feel your best. However, some prefer splitting the dose between morning and early afternoon due to NMN's half-life.

How much NMN should be taken per day?

A typical daily dosage of NMN ranges from 250 to 500 mg, although some studies suggest doses up to 1,000 mg may be safe. It's best to start with a lower dose and gradually increase it, depending on your individual needs and tolerance.

How long does it take for NMN to work?

The effects of NMN can take several weeks to a few months to notice. You may experience benefits such as increased energy, improved metabolism, and enhanced cognitive function over time. Keep in mind responses may vary depending on factors like age, lifestyle, and dosage.

What is the difference between NAD, NMN, NR, and NMNH?

NAD (Nicotinamide Adenine Dinucleotide) is a vital coenzyme involved in energy production, DNA repair, and cell metabolism. NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) are both precursors to NAD+, meaning they are converted into NAD in the body to help boost its levels. NMNH (Nicotinamide Mononucleotide Hydrochloride) is a specific form of NMN thought to elevate NAD+ levels and sustain them longer with a enhanced stability compared to regular NMN. While NMN and NR both increase NAD+ levels, they differ in their chemical structures and the pathways by which they are converted to NAD.

What's the difference between the caps and powder?

The main difference between NMN capsules and powder is the consumption form. NMN capsules offer a convenient, pre-measured dose, making them easy to take for travel, while NMN powder allows for flexible dosing and can be mixed into liquids, offering more control over the amount taken. However, NMN powder may have a shorter shelf life once opened and may require careful handling to ensure accurate dosing. Both forms are effective, but individual preferences and lifestyle factors may determine which is the best option for you.

It makes a difference

"I have been taking 2 capsules a day for over a month and I can tell a difference in how I feel. At first I couldn't quite tell what was different but then I realize the NMN was the difference."

— Lisa B. (5/5)

I’m giving it a 4

"I’m giving it a 4 because I haven’t taking it very long. I’ve forgotten to take it a few times and then realized I wouldn’t be taking it on an empty stomach so refused to take it on those mornings. Will get into the habit of taking it every morning. Have great expectations."

— Linda M. (4/5)

NMN review

"The reason I tried this supplement was my head just felt foggy and disconnected, about 3 weeks in things started clearing up and my focus was much better."

— Robert W. (5/5)

on my 4th bottle and here's why

"Been taking this since April 2025 and it's now 10/16/25 - the pain reduction in my back has significantly decreased - this was a completely unexpected side effect! I used to wake up super stiff in the morning, having a super hard time bending over - I had back surgery 10 years ago and my hip flexors just squeezed my spine so much that I needed surgery. Now I'm bending over w/o issue, picking things up, not suffering like I used to, and improving daily. mental fog is gone, my memory is improving, and I finally got motivated to work out every week because I finally have the energy and stamina and agility to do this. Prior to this I changed my eating habits 2 years following the glucose goddess method, so this has been a long road that I've invested into myself with better health and habits. so this is def not a quick fits, it takes commitment to all areas of your life. I still have stiffness in my lower back but I know with better workouts and stretching I'll get there. I also have ADHD so I made sure this was a great fit with my DNA/epigenetics because I have the MTHFR variant."
