NAD+ Look and Feel Younger

You may be familiar with vitamin B3, or nicotinamide. Nicotinamide in various forms when supplemented, may be more bio available and bio effective for our cells.

B3 converts biochemically to NAD+, an essential biological molecule in our body that supports the functioning of our cells. We feel this as energy, an alert brain, efficient detoxification, healthy cholesterol production, healthy aging and a good sleep helper. Basically, nicotinamide is a molecular power communicator. 

The association between metabolism, health and longevity has long thought to be linked, based on similarities between the aging process, metabolic dysfunction and disease (obesity, diabetes, neurodegeneration, related cancer). These disease processes, dysfunctions and disorders have been influenced by multiple proteins, including sirtuins and PARPs, these are tightly controlled through the balance and regulation of NAD+.

When supplementing with nicotinamide, levels of NAD+ are increased, and  negative effects of the aging process may be decreased.

Think of -

  • Energy for cells in the body to function more efficiently - fatigue and muscle action
  • Healthy aging - not too fast and avoiding age-related diseases
  • Brain health - food for the brain
  • Heart health - blood vessel function, blood pressure
  • Liver health - detoxification, fatty liver, obesity
  • Metabolism - efficient functioning of every cell
  • Circadian rhythms - associated with disease

What Depletes NAD+

Aging and Lifestyle - Unfortunately, aging depletes NAD, but your day to day activities can also cause a depletion of NAD+. This can include excess alcohol and coffee consumption, refined foods, over-eating, excess sun exposure, and not following a good sleep pattern (shift workers, time zone travellers).

Other factors include:

  • Neurodegenerative disease (dementia)
  • Heart disease
  • Chronic inflammation

Looking a Little closer – without getting complicated

Cell energy

Put simply, cell energy refers to the conversion foods/fuel for cells to function.

The food we eat has to be broken down to their smallest components for our cells to be able to utilise it for fuel. These components are transported into the mitochondria of the cell. Protein, carbohydrate and fat - amino acids, sugar and lipids.

Cell energyMitochondria are tiny power houses within our cells. 

The mitochodria take the energy from the food we eat and convert it into another energy - in the form of adenosine triphosphate (ATP), which is then used to fuel other cellular processes

 

Efficient functioning mitochondria equals lots of energy in all systems of the body

Back to food for fuel – a hard working coenzyme called nicotinamide adenine dinucleotide (NAD) is needed to store the energy from the breakdown of food into those smaller components. NAD is found in every living cell and is involved in many biochemical oxidation-reduction reactions.

When our cells need fuel to perform vital functions they rely on the glucose and fatty acids from the food we eat.

Nicotinamide supplement may promote this function and make the process more efficient!

Aging

NAD plays a vital role in how quickly we age.

Catch 22 – as we grow older our NAD declines, as our NAD declines our cells get older and we experience this through the outward signs of aging. It is not just on the outside we notice the signs of aging, Mitochondrial depletion of NAD in the cells is one of the major causes of aging and this can affect all areas of the body.  Loss of muscle strength and fatigue, along with other more serious aging issues such as insulin resistance, vascular inflammation and also other annoying occurrences, such as increased fat storage and increased fat production.

Nicotinamide can support an improved aging environment

Brain Health

Nerve cells in the brain called neurons require an enormous amount of cellular energy to perform. Certain conditions can cause these cells to deplete the resources, making it harder for recovery. Stroke, brain trauma and Alzheimer's disease are some conditions that may be affected. Recent studies have shown that enhancing NAD+ levels can greatly reduce oxidative cell damage of metabolic tissue, including the brain. Nicotinamide riboside acts on the brain by normalizing levels of NAD+.

In Alzheimer’s disease, the brain’s usual DNA repair activity is impaired, leading to mitochondrial dysfunction, lower neuron production, increased neuronal dysfunction and inflammation.

Nicotinamide can offer a therapeutic strategy for age-associated degenerative diseases

Cardiovascular disease

The inner surface of blood vessels is lined with a layer of cells, vascular endothelial cells, which serve as a barrier protecting the microenvironment and homeostasis. 

Cardiovascular diseaseDeterioration of either the structure or function of endothelial cells results in a variety of cardiovascular diseases. 

Not only that, if our mitochondria are not working properly, then the heart will not generate the energy it needs, leading to heart failure.

NAD has a supporting action in the mechanisms of cell protection.

Mitochondrial function can be improved by taking supplements of Nicotinamide

Liver

The liver is one of the most important and busiest organs in our body. Some of its roles include converting potential life-threatening components of metabolism and ingestion into safe metabolites for excretion, and metabolizing the substances we make in our bodies, such as hormones and neurotransmitters. By supporting the production of NAD and mitochondrial function, our liver function is enhanced and conditions such as fatty liver and inflammation are reduced. Recent studies have confirmed that NAC+ can reduce the effects of alcohol on the liver and prevent fat accumulation.

Nicotinamide can enhance Liver function

​SleepSleep

The circadian clock is an internal clock system that lets us know when it’s time to sleep and time to be awake, allowing for a rhythmic function of the body over a 24-hour period. This is known as the circadian rhythm. Aging and age-related diseases have been associated with circadian rhythm irregularies.

NAD+ metabolism has a close relationship with the efficient functioning of the circadian clock. 

Nicotinamide may help with regulating Circadian Rhythms

Metabolism

Metabolism is chemical transformations that takes place within our cells – converting food or fuel to energy for cellular processes. Nicotinamide can help our cells be more metabolically active supporting more efficient use of insulin, cholesterol, liver function and be less responsive to inflammatory mediators that cause disease.

High Fat Diet Obesity

NAD prevents the detrimental metabolic effects of high-fat diets.

High Fat Diet ObesitySirtuins regulate important biological pathways in our cells. Sirtuins have been implicated in influencing aging, cell death, inflammation and circadian rhythms processes.  

Nicotinamide can protect against high-fat diet-induced metabolic abnormalities

Why Would You Want to Take Nicotinamide?

  • Anti-aging
  • Mitochondrial efficient functioning
  • Improve longevity
  • Over-weight metabolic protection
  • Circadian rhythm support

Nicotinamide increases NAD+ levels in all cells and tissue

When you take various forms of Nicotinamide you can directly increase your levels of nicotinamide riboside an active form of Nicotinamide. Taking a Nicotinamide supplement may improve the levels of Nicotinamide riboside in the body than what you may receive from B3 in your diet. NAD is continuously being used and replenished in our body and a dosage of 250mg of Nicotinamide or more daily is suggested to maintain and elevate natural aging levels.

You can find upper limits of nicotinamide suggested by the Australian Government’s Nutrient Reference Values of Australia and New Zealand Click Here which suggest an upper limit of 900mg of nicotinamide daily. Nicotinamide salts are proven to be more bioactive than nicotinamide alone so smaller amounts can be used.

Summing up

Nicotinamide may boost NAD+ levels supporting optimum metabolic function, mitochondrial function and the production and storage of energy. This means you may see benefits in staying healthy, being clear headed, improving detoxification, reducing inflammation, reducing heart disease and sleeping better. Your cells may have improved energy that helps you to look and feel younger.

Speak to your Practitioner or Pharmacist if you feel Nicotinamide supplementation could benefit you and your health.
