Product details

What is NMN?

NMN is crucial for producing NAD+, essential for cellular energy. As we age, our NAD+ production declines, dropping to about half by age 50. MASI's Premium NMN, backed by research from The Mayo Clinic and Harvard University, offers a way to replenish NAD+, counteracting aging, and promoting sustained health and youthfulness.

✓ Restore vitality in all cells of the body

✓ Regenerate NAD+ levels to 100% of the body's optimal limit

✓ Counters natural effects of aging

NMN, a naturally occurring compound, plays a crucial role in the production of nicotinamide adenine dinucleotide (NAD+), a coenzyme vital for various biological processes in the body, including energy metabolism, DNA repair, and cellular signaling. 

Although NMN is present in modest quantities in foods like broccoli, avocados, and cucumbers, its anti-aging potential and its ability to extend lifespan and promote longevity have led many individuals to opt for NMN supplementation to enhance their NAD+ levels and bolster overall health.

Dosing

One capsule contains 500 mg of NMN. A two-capsule serving provides 1000 mg.
Recommended dosage:
40-50 years - 1 capsule per day;
50 years and more - 2 capsules per day

Recommendations: Take one or two capsules daily. To maximize absorption, take on an empty stomach in the morning, preferably 1 hour before breakfast.

Serving & supply

Each jar contains 60 capsules. Two capsules provide 1000 mg and a 30-day supply. One capsule daily gives up to two months of supply.

NMN (NAD+) Benefits

NMN is a precursor to NAD+ and is quickly converted to NAD+ when ingested. By increasing NAD+ levels, NMN may help support healthy aging and promote longevity by supporting various cellular processes. Research suggests that NMN may have a wide range of health benefits, including:

Promote healthy aging and longevity: NMN has been shown to promote healthy aging by improving overall health and vitality, supporting healthy cellular function, and reducing the risk of age-related diseases. In animal studies, NMN supplementation suppressed age-associated body weight gain, enhanced energy metabolism, promoted physical activity, improved insulin sensitivity and plasma lipid profile, and ameliorated eye function and other age-related decline2. Research continues to demonstrate the ability of NMN supplementation to increase life span in many animal models of aging3,4, suggesting that it may have similar benefits in humans.

Supports DNA repair: NMN also plays a role in repairing damaged DNA through its function in NAD+-dependent enzymes, including the Sirtuin family4. DNA repair is important for maintaining healthy cellular function and preventing the development of age-related conditions.

Enhances cognitive function: As we age, cognitive decline is a common concern. NMN has been shown to improve cognitive function in animal studies5, suggesting that it may have similar benefits in humans.

Supports cardiovascular health: NMN may also support cardiovascular health by improving endothelial function, reducing inflammation, and reducing oxidative stress6–8.

Improves insulin sensitivity: Insulin resistance is a common problem as we age, but NMN may help improve insulin sensitivity and support healthy glucose metabolism9–11.

Improving health and longevity depends on individual factors such as age, diet, and lifestyle. To maximise the benefits of our supplements, we recommend incorporating them into a comprehensive anti-aging regimen that includes healthy eating, regular exercise, and other lifestyle factors that promote longevity and healthy aging.

What real members say about MASI Premium NMN.

★★★★★

Highest quality NMN I've tested

It is my recommendation that anyone over 40 years of age looks into NMN. Clinical studies have shown it can support NAD+ — the cellular co-factor involved in energy production, which naturally declines with age. NMN, as a precursor, is well-studied for replenishing those NAD+ levels and supporting healthy-aging biomarkers.

★★★★★

Biggest game changer in my nootropic stack

I never write reviews, but these products are worth one. I ordered the nmn + Spermidine combo without expecting anything crazy, let me tell you how wrong I was. My skin, visibly smoother, my energy levels, steady with no crashes, even with caffeine.

Daniel

★★★★★

A year in and the energy is unmatched

I've been taking MASI NMN for more than a year and the difference in my daily energy is noticeable. I used to take Lion's mane, l-theanine and other well-known supplements but for me, MASI NMN has been the most useful one in my routine at my age. I pair it with lower doses of caffeine and feel I get more done day to day.

★★★★★

Felt the difference within the first month

The Masi Longevity and Reservatrol products are of great quality. I am in my 60's, and have felt a difference within the month of taking each one. I feel more clarity, focus, and much sharper!

Healthy aging is linked to NAD+ levels

What is NAD+?

Research featured in the prestigious journal Nature Aging indicates a significant correlation between levels of NAD+ and overall health during human aging.

NAD+, short for nicotinamide adenine dinucleotide, is a critical compound present in every cell of the human body. This molecule plays a vital role in numerous biological processes, acting as a key player in the metabolic reactions that power our cells and, by extension, our entire bodies. Its presence and function are fundamental to maintaining cellular vitality.

Nicotinamide

Adenine

Dinucleotide

Unfortunately, NAD+ levels decline with age.

Studies indicate that starting anti-aging efforts in your 30's is optimal. Incorporating NAD+ enhancers like NMN into your daily regimen can rejuvenate NAD+ levels to what they were in your 20's, effectively aiding in the anti-aging process.

Renowned Harvard scientist David Sinclair defends this stance with his research, highlighting the critical role of sirtuins - a family of proteins that depend on NAD+ and are essential for cellular health. Sirtuins regulate cellular processes like DNA repair, inflammation reduction, and mitochondrial function. NMN, a precursor to NAD+, is crucial in this process as it helps replenish declining NAD+ levels, effectively rejuvenating cells and mirroring the vitality experienced in one’s 20s.

Sinclair’s studies affirm the significant impact of NAD+ and NMN in promoting longevity and combating the signs of aging.
