NAD+ & Cellular Health
Understanding the Biology Behind Cellular Energy
Every cell in the body depends on complex biological processes to produce and use energy.
NAD+—short for nicotinamide adenine dinucleotide—is a naturally occurring coenzyme involved in many of these cellular processes.
Interest in NAD+ has grown considerably within the fields of metabolism, cellular biology and aging research.
At Ontario Regenerative Medicine, we believe the best place to begin isn’t with a product or treatment.
It’s with understanding your health.
What Is NAD+?
NAD+ stands for nicotinamide adenine dinucleotide.
It is a naturally occurring coenzyme found in cells throughout the body.
A coenzyme is a molecule that helps enzymes carry out biochemical reactions.
NAD+ participates in fundamental cellular processes involving energy metabolism and cellular function.
Rather than thinking of NAD+ as a treatment itself, it can be helpful to understand it as part of the body’s normal cellular biology.
What Does NAD+ Do in the Body?
NAD+ Participates in Cellular Metabolism
Cells need to convert nutrients into forms of energy they can use.
NAD+ participates in biochemical reactions involved in this process.
It functions as an important electron carrier in cellular metabolism, cycling between different molecular forms as cells carry out metabolic reactions.
NAD+ & Mitochondria
Understanding Cellular Energy Production
Mitochondria are structures within cells involved in energy production.
NAD+ participates in metabolic pathways connected with mitochondrial function and cellular energy metabolism.
This relationship is one reason NAD+ has become an area of interest in research examining metabolism and the biology of aging.
It’s important, however, to distinguish the normal biological role of NAD+ from claims that increasing NAD+ will necessarily improve energy, reverse aging or treat a medical condition.
Those are different questions.
NAD+ & Aging Research
Why Are Researchers Interested in NAD+?
Scientists continue to study how cellular metabolism changes with age.
NAD+ has attracted research interest because of its involvement in several fundamental cellular processes.
Research into NAD+ metabolism includes investigation of:
- cellular energy metabolism
- mitochondrial biology
- cellular signalling
- metabolic pathways
- mechanisms associated with aging
This is an evolving area of scientific research.
Research interest in a biological molecule should not be interpreted to mean that increasing that molecule has been established as a way to prevent, reverse or treat age-related disease.
Do NAD+ Levels Change With Age?
Changes in NAD+ metabolism have been observed in aging research.
However, aging is an extremely complex biological process involving many interacting systems.
Changes in energy, cognition, sleep, body composition or general well-being should therefore not automatically be attributed to NAD+.
There may be many possible explanations for these concerns.
That’s why ORM begins with assessment rather than assuming a particular biological pathway is responsible.
Feeling Different Than You Used To?
People often become interested in NAD+ because they’ve noticed changes in how they feel as they get older.
You may have questions about:
- energy
- sleep
- concentration
- body composition
- physical performance
- recovery
- general well-being
- healthy aging
These concerns are real, but they are also nonspecific.
They can be influenced by numerous medical, hormonal, nutritional, lifestyle and other factors.
They do not establish that you have “low NAD+.”
Can I Test My NAD+?
Start With the Clinical Question
A wellness assessment shouldn’t be built around finding one particular laboratory abnormality.
If you’ve noticed changes in energy, sleep, body composition, performance or general well-being, your healthcare provider can determine which aspects of your health warrant further evaluation.
Depending on your individual circumstances, that may involve reviewing:
- medical history
- medications and supplements
- sleep
- nutrition
- physical activity
- hormone health
- body composition
- appropriate laboratory investigations
- other relevant health factors
The objective is to understand the individual rather than assume that NAD+ is the explanation.
Healthy Aging Is Bigger Than One Molecule
Look at the Whole Picture
There is enormous interest in longevity and healthy aging.
But no single molecule provides a complete picture of how well someone is aging.
Health throughout adulthood can be influenced by factors involving:
- cardiovascular and metabolic health
- skeletal muscle
- body composition
- nutrition
- physical activity
- sleep
- hormone health
- medications
- medical conditions
- lifestyle
- other individual factors
ORM’s approach is to consider these factors together when they’re relevant to the patient.
Cellular Health & Muscle Health
Skeletal muscle is an important component of physical health throughout adulthood.
ORM’s muscle-health and body-composition services can provide additional information about areas such as muscle mass and body composition.
These measurements don’t directly measure “cellular age,” but they can provide useful objective information within a broader health assessment.
NAD+ Isn’t a Diagnosis
Terms such as “NAD+ deficiency” or “declining NAD+” can make it sound as though common concerns such as fatigue or difficulty concentrating can be diagnosed simply by recognizing symptoms.
It’s more complicated than that.
Fatigue, changes in concentration, sleep difficulties, body-composition changes and similar concerns can have many possible causes.
Medical assessment can help determine which factors warrant investigation.
Symptoms are the beginning of the conversation—not the diagnosis.
What About NAD+ Treatments?
NAD+-related products and methods of administration are an area of significant public interest.
Whether a particular health product or medical treatment is appropriate is a separate question from understanding the normal biological role of NAD+.
At ORM, treatment decisions begin with individualized medical assessment.
If a healthcare provider determines that a particular medical treatment should be considered, the specific treatment can be discussed directly with the patient as part of their individual care.
That discussion can include:
- why the treatment is being considered
- available evidence
- potential benefits
- potential risks and side effects
- limitations and uncertainties
- alternatives
- monitoring requirements
