IS NMN MORE EFFECTIVE THAN NR

There’s a lot of research going on right now with Nicotinamide Mononucleotide (NMN) and Nicotinamide Riboside (NR). It can be difficult to make sense of them all, so we summarize some results that lead us to believe NMN is more effective than NR.

DRAMATIC RESULTS WITH NMN IN ENDURANCE AND YOUTHFULLNESS

Below are the three studies that made the biggest splash’s about the potential for reversing aging by restoring NAD+ to youthful levels that have ALL been accomplished using NMN

After 6 days of NMN, 22 month old mice  had the muscle capacity, endurance and metabolism of 6 month old  mice (2013 Sinclair study)

NMN effectively mitigates age-associated physiological decline in mice (2016 Mills Long Term study)

“The old mice became as fit and strong as young mice” (Sinclair, 2018)

This third study recently published by Dr Sinclair is a  good example.

Mice that received NMN had nearly 100% increased endurance vs the control mice, and actually grew NEW blood vessels. This was after 60 days, in 20 month old mice (equivalent to 90 year old humans).

Along with the impressive increased endurance, the study shows  NAD+ increase is over 500% at 60 days

RESULTS NOT AS IMPRESSIVE WITH NR

In this 2016 study, 22-24 month old mice were given NR for 6 weeks.

Running distance and duration were improved approximately 20%.

The treatment duration was slightly shorter in this study than with NMN (6 weeks vs 8 weeks), there is a huge difference in the benefit with increased endurance from NMN nearly 100% vs the 20% with NR.

Treating Heart Disease

2 separate studies to treat a form of heart disease called Friedreich’s Ataxia with NR and NMN were published in 2017. Treatment with NMN was successful, while NR did not improve cardiac function.

“Remarkably, NMN administered to FXN-KO mice restores cardiac function to near-normal levels. “(Martin, 2017)

“In conclusion, NAD+ supplementation with NR in the FRDA model of mitochondrial heart disease does not alter SIRT3 activity or improve cardiac function.”(Stram, 2017)

COMBATTING ALZHEIMERS DISEASE

Alzheimer’s disease (AD) pathogenesis is widely believed to be driven by the production and deposition of the β-amyloid peptide (Aβ). Evidence now indicates that the solubility of Aβ, and the quantity of Aβ in different pools is related to disease state (r).Researchers believe that flaws in the processes governing production, accumulation or disposal of beta-amyloid are the primary cause of Alzheimer’s (r).

In studies published in 2017 and 2018 NMN decreased β-amyloid buildup, while NR did not.

“NR lessened pTau pathology in both 3xTgAD and 3xTgAD/Polβ+/− mice but had no impact on amyloid β peptide (Aβ) accumulation”(Hou, 2018)

“NMN decreased β-amyloid production, amyloid plaque burden, synaptic loss, and inflammatory responses in AD-Tg mice” (Yao, 2017)

NMN was able to mitigate most age-associated physiological declines in mice Treatment of old mice with NMN reversed all of these biochemical aspects of aging

Long-Term Administration of Nicotinamide Mononucleotide Mitigates Age-Associated Physiological Decline in Mice (mills, 2016)

Raising NAD+ levels in old mice restores mitochondrial function to that of a young mouse

Restore the mitochondrial homeostasis and key biochemical markers of muscle health in a 22-month-old mouse to levels similar to a 6-month-old mouse

Declining NAD+ Induces a Pseudohypoxic State Disrupting Nuclear-Mitochondrial Communication during Aging (Gomes, Sinclair,2013)

DNA Repair

This study showed supplementation with NMN was able to repair the DNA in cells damaged by radiation

The cells of old mice were indistinguishable from young mice after just one week of treatment.

WEIGHT

NMN was immediately utilized and converted to NAD+ within 15 min, resulting in significant increases in NAD+ levels over 60 min

Administering NMN, a key NAD+ intermediate, can be an effective intervention to treat the pathophysiology of diet- and age-induced T2D

Surprisingly, just one dose of NMN normalized impaired glucose tolerance

Nicotinamide Mononucleotide, a Key NAD+ Intermediate, Treats the Pathophysiology of Diet- and Age-Induced Diabetes in Mice (Yoshino, 2011)

NAD(+) levels were increased significantly both in muscle and liver by NMN

NMN-supplementation can induce similar reversal of the glucose intolerance

NMN intervention is likely to be increased catabolism of fats NMN-supplementation does mimic exercise

Head to Head Comparison of Short-Term Treatment with the NAD(+) Precursor Nicotinamide Mononucleotide (NMN) and 6 Weeks of Exercise in Obese Female Mice (Uddin, 2016)

NMN significantly increased the level of NAD+ in the heart

NMN protected the heart from I/R injury

Nicotinamide mononucleotide, an intermediate of NAD+ synthesis, protects the heart from ischemia and repercussion (Yamamoto, 2014)

NMN reduces vascular oxidative stress

NMN treatment normalizes aortic stiffness in old mice

NMN represents a novel strategy for combating arterial aging

Nicotinamide mononucleotide supplementation reverses vascular dysfunction and oxidative stress with aging in mice (de Picciotto, 2016)

NMN can reduce myocardial inflammation NMN thus can cut off the initial inflammatory signal, leading to reduced myocardial inflammation

Short-term administration of Nicotinamide Mononucleotide preserves cardiac mitochondrial homeostasis and prevents heart failure (Zhang, 2017)

ENERGY

Remarkably, NMN administered to FXN-KO mice restores cardiac function to near-normal levels.

Restoration of cardiac function and energy metabolism upon NMN supplementation

Remarkable decrease in whole-body EE and cardiac energy wasting

VISION

Exogenous NMN prevents photoreceptor degeneration and restores vision

NMN rescues retinal dysfunction in light-induced degeneration

 

NAMPT-mediated NAD+ biosynthesis is essential for vision in mice (lin, 2016)

Completed and pending publication

Beginning 2018

  • 2018 Sinclair Metrobio study – Phase 2

The Phase 1 study by Dr Sinclair has been completed, and they are ready to go forward with the Phase 2 study, so we can conclude there were positive results, and no negative side effects, else they would have to publish those immediately.

In the University of Washington study, participants are 50 healthy women between 55 and 70 years of age with slightly high blood glucose,BMI and triglyceride levels.

Using a dose of 2 capsules of 125mg NMN per day over a period of 8 weeks, researchers are testing for:

  • change in beta-cell function
  • works to control blood sugar
  • blood vessels dilate
  • effects of NMN on blood lipids
  • effects of NMN on body fat
  • markers of cardiovascular and metabolic health

The active supplementation portion of this study has ended, but testing of metabolic parameters will continue for 2 years after supplementation has ended.  So researchers know the immediate effects and  preliminary results are expected to be announced in 2018, with  final results expected in 2020.
 

Elevates NAD+ quickly throughout the body

In this 2016 study, mice were given a single dose of NMN in water.

NMN levels in blood showed it is quickly absorbed from the gut into blood circulation within 2’“3 min and then cleared from blood circulation into tissues within 15 min

Increases NAD+ and Sirt1 Dramatically in organs

The charts at left from 2017 study, NMN supplementation for 4 days significantly elevated NAD+ and SIRT1, which protected the mice from Kidney damage.

NAD+ and SIRT1 levels were HIGHER in OLD Mice than in YOUNG Mice that did not receive NMN.

    The Martin study gave 500 mg/kg of NMN. In a 70 kg person, this translates to a dose of 35,000 mg twice weekly or 70,000 mg per week! You suggest 250 mg daily for people (1750 mg over the course of a week). What possible relevance does such a massive dosage in rodents have to do with 250 mg daily in people?

    First of all I would like to say excellent blog! I had a quick question in which I’d like to ask if you don’t mind. I was interested to find out how you center yourself and clear your mind prior to writing. I’ve had difficulty clearing my thoughts in getting my thoughts out. I truly do enjoy writing but it just seems like the first 10 to 15 minutes are wasted simply just trying to figure out how to begin. Any recommendations or tips? Many thanks!

    You really make it seem so easy together with your presentation however I in finding this matter to be really one thing which I believe I’d by no means understand. It kind of feels too complex and extremely huge for me. I am looking ahead for your next post, I’ll try to get the dangle of it!

    Very well written article. It will be useful to anyone who usess it, including yours truly :). Keep doing what you are doing – looking forward to more posts.
