NMN (Nicotinamide Mononucleotide)

What Is NMN (Nicotinamide Mononucleotide)?

NMN is a compound your body makes from vitamin B3, and it's one of the building blocks your cells use to make NAD+. NAD+ is a coenzyme every cell needs — it helps the mitochondria turn food into energy and keeps the cell's everyday repair work running. [1]

The catch is that NAD+ doesn't stay at the same level for life. Research shows it falls with age in the skin, blood, muscle, liver and brain — brain scans have found levels around 10 to 25% lower in older adults than in young adults. [1]

NMN is also found naturally in food, in small amounts:

Vegetables like cabbage, tomato, mushroom and soybean [1]
Fruits like orange, pear and cherry [1]
Seafood and meat like shrimp, scallops, salmon and beef [1]

These amounts are tiny, though — a normal diet likely gives you 2 mg of NMN a day or less, far below the 250 to 900 mg used in most human studies. That gap is why many people choose to supplement NMN to help support their body's NAD+ levels as the years go by. [1,8]
You might see it on a label as NMN, β-NMN, Beta-Nicotinamide Mononucleotide, or β-Nicotinamide Mononucleotide — they all mean the same compound. [1,2]

Why Choose D-Dukaan's NMN?

You'll find NMN in Scotmann's Sinclair NMN, available in two strengths so you can pick the one that suits you: a 250 mg capsule for a gentle, foundational start, and a 500 mg capsule for a more concentrated daily dose. It's made for adults 25 and older who want to support healthy ageing early, not as a quick fix but as a steady daily habit. [2,3]

The 500 mg capsule sits inside the 300 to 900 mg range tested in a 60-day trial of healthy adults aged 40 to 65, where all three doses raised blood NAD+ levels. In that study, 600 mg gave the strongest results and 900 mg added no further benefit — so one 500 mg capsule puts you close to the best-performing amount in a single, simple dose. [2,8]

Both strengths come in packs of 30 capsules, made with halal-certified ingredients to GMP standards, and carry DRAP, ISO 9001, TÜV Austria and PNAC marks. NMN is water-soluble, so it's simple to take — just swallow a capsule whole with water. [2,3]

Taking Scotmann's Sinclair NMN regularly may offer:

Support for your body's NAD+ levels — raising blood NAD+ is the most consistent finding in human NMN research. [1,8]
Support for cellular energy and longevity — NAD+ powers the energy and repair work inside every cell. [1,2]
Support for physical stamina — linked in research to better walking endurance and aerobic capacity. [5,8]
A dose backed by recognised manufacturing standards — GMP, DRAP, ISO 9001, TÜV Austria and PNAC. [2,3]

Uses & Benefits of NMN

Uses & Benefits	Description
Supports cellular energy and NAD+ levels	In a 60-day trial of 80 healthy adults aged 40 to 65, blood NAD+ rose significantly at 30 and 60 days in every group taking NMN (300, 600 or 900 mg a day), while the placebo group saw no change. This is the most consistent result across NMN research. [1,8]
Supports physical stamina and walking distance	In the same trial, people taking 600 mg or 900 mg a day walked noticeably further in a six-minute walking test than when they started. [8]
Helps maintain biological age markers and quality of life	Using a blood-test–based measure of biological age, the placebo group's biological age rose over 60 days, while it held steady in all the NMN groups. Everyone taking NMN also reported better scores on a standard quality-of-life survey (SF-36). [8]
Supports aerobic capacity for active adults.	In a 6-week study of 48 amateur runners, those taking 600 mg or 1,200 mg of NMN a day alongside their training improved their aerobic capacity more than those on a placebo — most likely because their muscles used oxygen more efficiently. [5]
Promotes healthy muscle glucose uptake	In a 10-week trial, postmenopausal women with prediabetes who took 250 mg of NMN a day saw better insulin sensitivity in their muscles — meaning their muscles took up blood sugar more effectively — along with stronger activity in genes linked to muscle structure and remodelling. [4]
Supports lower-limb function in later life.	In a 12-week study of 108 adults aged 65 and over taking 250 mg a day, the group that took NMN in the evening showed the largest improvement in a chair-stand test of leg strength. Researchers see this as an encouraging early sign for staying active with age. [6]
Heart and metabolic markers: early research	In a 28-day study, overweight adults aged 45 and over taking a high 2,000 mg a day of a patented NMN form saw lower LDL cholesterol, a small drop in body weight and lower diastolic blood pressure compared with placebo. In a separate 12-week study at 250 mg a day, arterial stiffness tended to improve, though the difference from placebo wasn't statistically significant. A 2024 review of 8 trials found no consistent effect on blood sugar or blood fats overall, so this area still needs larger studies. [11,12,13]

NMN Clinical Research at a Glance

Here's a quick summary of the main human studies behind this page:

Study	Who took part	Daily dose	What it found
Yi et al., 2023 — 60 days	80 healthy adults aged 40–65	300, 600 or 900 mg	Blood NAD+ rose in all NMN groups; longer walking distance at 600–900 mg; biological age held steady vs placebo; better quality-of-life scores. 600 mg performed as well as 900 mg [8]
Yoshino et al., 2021 — 10 weeks	25 postmenopausal women with prediabetes	250 mg	Better insulin sensitivity in muscle; more activity in muscle-remodelling genes [4]
Liao et al., 2021 — 6 weeks	48 trained amateur runners	300, 600 or 1,200 mg	Improved aerobic capacity at 600 and 1,200 mg, likely from better oxygen use by muscle [5]
Kim et al., 2022 — 12 weeks	108 adults aged 65+	250 mg (morning or evening)	Evening intake showed the largest improvement in a chair-stand test of leg strength [6]
Pencina et al., 2023 — 28 days	30 overweight adults aged 45+	2,000 mg	Raised NAD+; lower LDL cholesterol, body weight and diastolic blood pressure vs placebo [11]
Katayoshi et al., 2023 — 12 weeks	36 healthy middle-aged adults	250 mg	Arterial stiffness tended to fall, but not significantly vs placebo [12]
Fukamizu et al., 2022 — 4 weeks	31 healthy adults aged 20–65	1,250 mg	No safety concerns in blood tests, vital signs or body measurements [7]
Irie et al., 2020 — single dose	10 healthy men	100, 250 or 500 mg	Well tolerated; showed oral NMN is feasible in humans [1,9]

NMN Dosage

There's no single official daily amount for NMN yet. Human studies have used anywhere from 100 mg to 2,000 mg a day, with 250 mg the most common amount tested. [1]

D-Dukaan's guidance for Scotmann's Sinclair NMN is one to two capsules a day, or as directed by a qualified healthcare practitioner. That gives you a range of 250 mg to 1,000 mg a day depending on the strength you choose. In the 60-day dose trial, 600 mg a day gave the strongest results, and 900 mg did no better — so one 500 mg capsule is a well-placed everyday amount. [2,3,8]

When To Take NMN

Pick a time that fits your day, and stick to it — taking NMN at the same time each day makes it easy to build a habit. Swallow the capsule whole with water; unlike fat-soluble nutrients, NMN doesn't need a meal with fat to be absorbed. [2,3]

If you're an older adult, one study found that taking NMN in the evening (after 6 pm) gave slightly stronger results for leg strength than taking it in the morning — a small, early finding, but an easy one to try. [6]

Things To Know About NMN

NMN has been well tolerated in human studies so far. Single doses of up to 500 mg caused no problems in healthy men; 900 mg a day for 60 days was described as safe and well tolerated; and 1,250 mg a day for 4 weeks showed no safety concerns in blood tests, vital signs or body measurements. Even at 2,000 mg a day for 28 days, side effects were similar to placebo. [1,7,8,9,11]

Because NMN research is still fairly new, most studies have been short and small, and there's no official upper limit yet. That's why it's a good habit to stay within the label's one-to-two capsule range. If you're pregnant, breastfeeding, managing a medical condition, or taking prescription medicine — especially for blood sugar — check with your doctor first so your NMN routine fits your existing care. [1,2,4]

Final Thoughts on NMN

NMN gives your cells one of the building blocks they need to make NAD+, a coenzyme that powers energy and repair and naturally declines with age. Human research is still early but encouraging, with consistent rises in blood NAD+ and promising results for stamina, aerobic capacity, muscle metabolism and mobility. Scotmann's Sinclair NMN makes it simple to add to your day, in a 250 mg or 500 mg capsule backed by recognised manufacturing standards. [1,2,3,8]

FAQs on NMN

Is NMN the same as vitamin B3?

Not quite. NMN is made from vitamin B3 in the body, but it's its own compound — one step along the path your cells use to make NAD+. [1]

Why take NMN instead of NAD+ directly?

NAD+ is a large molecule that doesn't easily get into cells intact. NMN is smaller, and your body can turn it into NAD+ inside the cell. [1,2]

Which strength should I choose?

The 250 mg capsule is a gentle, foundational starting point, especially if you're new to NMN. The 500 mg capsule gives a fuller daily dose in a single capsule, close to the 600 mg amount that performed best in a 60-day trial. [2,3,8]

Can I take NMN every day?

Yes. NMN is designed for daily use, and it has been well tolerated in human studies at up to 900 mg a day for 60 days and 1,250 mg a day for 4 weeks. Stay within the label's one-to-two capsule range unless your doctor advises otherwise. [2,7,8]

What's the best time of day to take it?

Any consistent time works. In older adults, evening intake showed slightly stronger results for leg strength in one study. [2,6]

Is NMN allowed as a supplement?

Yes. In September 2025, the US FDA confirmed that NMN can be sold as a dietary supplement, reversing its earlier position. [10]

Does NMN interact with any medicines?

NMN's interactions haven't been studied much yet. If you take prescription medicine — especially for blood sugar, since NMN has been studied for its effect on insulin sensitivity — check with your doctor before starting. [1,2,4]

Who should check with a doctor first?

If you're pregnant, breastfeeding, managing a medical condition, or taking prescription medicine or several other supplements, get your doctor's go-ahead before starting NMN. [2,3]
