Trial Summary

Will I have to stop taking my current medications?

You may need to stop taking certain supplements, especially those containing niacin, nicotinic acid, nicotinamide, or herbal supplements, at least 14 days before starting the trial. If you are using a supplement with NAM, niacin, NMN, or NR, you must stop it at least 2 weeks before joining. Other medications like anabolic steroids, certain performance-enhancing drugs, and some recreational drugs are also prohibited.

What data supports the effectiveness of the drug Nicotinamide Mononucleotide (NMN) for healthy adults?

Research shows that NMN, a precursor to NAD+ (a molecule important for energy and cell repair), can increase NAD+ levels in humans, which may help with age-related conditions. In older adults, NMN has been found to improve sleep quality, reduce fatigue, and enhance physical performance.12345

Is the combination of NAM and NMN safe for healthy adults?

Research shows that NMN is generally safe for healthy adults when taken orally at doses up to 1250 mg daily for 4 weeks, with no severe side effects reported. However, high doses of NAM may have potential risks, such as changes in DNA and protein methylation, especially with long-term use.14678

How does the drug NAM + NMN differ from other treatments for age-related conditions?

The drug NAM + NMN is unique because it combines nicotinamide and nicotinamide mononucleotide, which are precursors to nicotinamide adenine dinucleotide (NAD+), a crucial coenzyme for metabolism. This combination aims to increase NAD+ levels, potentially counteracting age-related changes and improving metabolic health, which is different from other treatments that may not target NAD+ levels directly.145910

What is the purpose of this trial?

We are doing this research to learn how healthy younger and older adults use two forms of vitamin B3-called nicotinamide mononucleotide (NMN) and nicotinamide (NAM)-to make NAD+. NAD+ is a natural substance that cells need for energy and other important processes. Our goal is to find out how these NAD precursors are absorbed and metabolized and how they raise NAD+ in different tissues.Who can join? Healthy adults men and women aged 18 to 40 (younger group) or 65 and older (older group) Participants with a body mass index ranging between 19 and 35 No major health issues like diabetes or severe kidney diseaseWhat will happen? Participants will take labeled or unlabeled NMN or NAM by mouth every day for 14 days.Researchers will collect blood, urine, and stool samples. Researchers also do a small muscle biopsy (under local numbing) twice to check how these NAD precursors raise NAD+ in muscle.Why is this important? NAD+ levels may drop as people age, and this drop could affect overall health and energy in cells.A better understanding of how NMN and NAM are metabolized in the body to raise NAD+ levels in both younger and older adults may help us optimize dosing and strategies for raising NAD in older people.Possible benefits and risks:Participants may not get any direct health benefit from this study; the main goal is to gather new knowledge.NMN and NAM appear safe in the doses used. A muscle biopsy may cause soreness or bruising.Researchers will monitor participants closely for any side effects throughout the study.

Treatment Details

Interventions

  • Nicotinamide
  • Nicotinamide Mononucleotide
Trial Overview The trial tests how orally taken Nicotinamide Mononucleotide (NMN) and Nicotinamide (NAM) are metabolized in healthy younger and older adults. Participants will consume these substances daily for two weeks, while researchers monitor their effects on raising NAD+ levels in tissues through blood, urine, stool samples, and muscle biopsies.

Findings from Research

A study involving 31 healthy adults showed that daily oral administration of 1250 mg of β-NMN for 4 weeks is safe and well-tolerated, with no significant adverse effects reported.
The research indicates that β-NMN does not cause harmful changes in various health parameters, suggesting its potential for further exploration in age-related disease prevention.
Safety evaluation of β-nicotinamide mononucleotide oral administration in healthy adult men and women.Fukamizu, Y., Uchida, Y., Shigekawa, A., et al.[2022]
A study involving 108 older adults showed that taking nicotinamide mononucleotide (NMN) in the afternoon significantly improved lower limb function and reduced drowsiness after 12 weeks.
The NMN group demonstrated the largest improvements in physical performance, particularly in the 5-times sit-to-stand test, indicating its potential to enhance physical capabilities and combat fatigue in older adults.

The synthetic form of β-nicotinamide mononucleotide (NMN-C®) was found to be safe in a study involving acute and subchronic toxicity tests, with no mutagenic or genotoxic effects observed.
In a 90-day study with doses up to 1500 mg/kg/day, NMN-C® did not show any adverse effects, establishing a No-Observable Adverse Effect Level (NOAEL) of ≥1500 mg/kg/day, indicating its potential safety for short to intermediate-term use.
