Most people are searching for a quick anti-aging fix; however, most anti-aging products don’t work or are filled with toxic ingredients. While aging is inevitable, there are natural molecules that can help slow its effects. One molecule that has gained a lot of attention for its anti aging benefits is NAD+ (Nicotinamide Adenine Dinucleotide). NAD+ is a naturally occurring coenzyme found in all living cells. It’s critical for energy metabolism, DNA repair, and the regulation of important biological processes associated with aging.
Nicotinamide Adenine Dinucleotide was once only discussed in labs and research, but now it has made its way into mainstream wellness conversation. With the rise of supplements, IV therapy, and interest in biohacking, more people are discovering the benefits of NAD+. But what exactly is it, what are its health benefits, and how can it make you age better?
Let’s dive into the world of NAD+ and how it can enhance your overall well-being.
What Is NAD+?
As mentioned, Nicotinamide Adenine Dinucleotide is a coenzyme, meaning it’s a type of ‘helper’ molecule, that plays an essential role in many cellular reactions, particularly those related to energy production and metabolism. NAD+ is found in every cell of your body, and it’s necessary for the functioning of mitochondria, the specialized cell structures that convert food to energy (ATP).
It exists in two forms: NAD+ (oxidized) and NADH (reduced). These two forms move electrons back and forth during biochemical reactions, allowing cells to generate energy efficiently. But Nicotinamide Adenine Dinucleotide does more than increase energy; it also signals molecules involved in DNA repair, immune function, gene expression, and circadian rhythm regulation.
Unfortunately, NAD+ levels decline with age, exposure to stress, poor diet, and environmental toxins. This decline is associated with fatigue, a slowed metabolism, cognitive decline, and increased risk of chronic diseases. That’s why Nicotinamide Adenine Dinucleotide supplementation and lifestyle changes to boost natural Nicotinamide Adenine Dinucleotide production have become popular in the natural health industry.
What Are NAD+’s Key Health Benefits?
Boosting Nicotinamide Adenine Dinucleotide levels can benefit many bodily functions, from cognitive health to metabolism. Here are four top health benefits of NAD+:
1. Energy Production & Mitochondrial Function
At its core, Nicotinamide Adenine Dinucleotide is essential for converting food into energy. It acts as a coenzyme in redox (oxidation-reduction) reactions that generate ATP, the energy currency of cells. This process occurs primarily in the mitochondria.
As you age, reduced NAD+ levels contribute to mitochondrial dysfunction, which leads to fatigue, muscle weakness, and slower recovery. By restoring these levels, cells can maintain optimal energy production.
2. Brain Health & Cognitive Function
Your brain is one of the most energy-demanding organs, and Nicotinamide Adenine Dinucleotide plays a critical role in maintaining cognitive function. Other than energy production, NAD+ supports neurons by activating enzymes involved in DNA repair and protecting cells from oxidative damage.
Research shows that NAD+ supplementation may help protect against age-related cognitive decline, neurodegeneration, and memory loss. It’s been studied in connection with conditions such as Alzheimer’s disease, Parkinson’s disease, and general brain aging.
Nicotinamide Adenine Dinucleotide also helps regulate neurotransmitter synthesis and brain inflammation, contributing to improved focus, mood and overall mental clarity.
3. DNA Repair & Longevity
Nicotinamide Adenine Dinucleotide is indispensable for activating sirtuins, a family of proteins referred to as ‘longevity genes.’ These proteins regulate cellular stress responses, inflammation, and DNA repair mechanisms. Sirtuins require NAD+ to function, making this nutrient vital in slowing the cellular aging process.
NAD+ is also involved in the activity of PARPs (Poly ADP-Ribose Polymerases), enzymes that help repair DNA damage caused by environmental toxins and UV exposure. When Nicotinamide Adenine Dinucleotide levels are sufficient, cells can repair themselves more effectively, reducing the risk of mutation and dysfunction over time.
All of this helps keep your cells healthy and in turn, keeps your skin healthy too. By supporting your health on a cellular level, you can combat signs of aging and keep your skin glowing from the inside out.
4. Metabolic Health & Insulin Sensitivity
NAD+ is also a key component in maintaining metabolic balance. It supports enzymes that regulate blood sugar levels, fat metabolism, and insulin sensitivity. As Nicotinamide Adenine Dinucleotide levels decline, metabolic function tends to deteriorate, leading to weight gain and an increased risk of type 2 diabetes.
Supplementing with NAD+ precursors, such as Nicotinic Acid (NA), Nicotinamide (NAM), Nicotinamide Riboside (NR), Nicotinamide Mononucleotide (NMN), and Tryptophan, has been shown to improve glucose tolerance, enhance fat oxidation, and reduce overall inflammation in animal studies.
While more research is needed on human trials to confirm these findings, the current research is promising.
How To Use NAD+ Supplements
There are several ways to boost NAD+ levels, from lifestyle changes and diet to supplementation and IV therapy. The most effective and convenient methods for boosting Nicotinamide Adenine Dinucleotide are by increasing the amount of NAD+ precursors in your diet or through supplementation. The precursors that your body converts into Nicotinamide Adenine Dinucleotide include:
- NMN (Nicotinamide Mononucleotide) – a direct precursor that's found in supplement form, vegetables like broccoli, edamame and avocado, meat, and milk.
- NR (Nicotinamide Riboside) – a form of vitamin B3 that’s a direct precursor to NAD+ and can be found in supplement form, cow’s milk, broccoli, avocado, and edamame.
- NAD+ Booster Supplements – a combination of Nicotinamide Adenine Dinucleotide precursors. Products include, NAD+ Booster by Organika and Nadogen NAD+ SIRT1 by Provita.
- NAD+ IV Therapy – IV therapy administered by a qualified healthcare practitioner.
Of these, NMN and NR are the most popular supplement options. While NMN tends to be slightly more stable and offers better bioavailability, both of these options have been studied and findings show they significantly increase intracellular NAD+ levels.
Recommended Dosage:
- NR: typical doses range from 250-500mg per day, although it’s best to follow supplement label directions.
- NMN: 250-1000mg per day, or follow supplement label dosing directions.
- NAD+ IV: Administered in clinics under professional supervision.
It’s best to start with lower doses and work your way up to avoid potential side effects like an upset stomach. If you are taking other medications or have chronic health concerns, it’s best to consult your healthcare practitioner before taking these supplements.
Best Time To Take NAD+ Supplements:
Nicotinamide Adenine Dinucleotide boosters should generally be taken in the morning due to their ability to increase energy.
Shopping For NAD+ Supplements In Canada
Like any other supplement, it’s important to choose a NAD+ supplement that is made with quality ingredients and from a trusted natural health brand. Always look for supplements that are third-party tested when possible and don’t contain unnecessary fillers.
Potential Side Effects of NAD+ Supplements
NAD+ supplements and their precursors are generally considered safe and well-tolerated, but there are a few potential side effects and considerations to be aware of.
Mild Digestive Upset: Some people may experience nausea, bloating, or stomach discomfort. This is why it’s best to start with a lower dose and gradually increase.
Flushing: Although more common with nicotinic acid, some people report mild skin flushing with some Nicotinamide Adenine Dinucleotide precursors.
Sleep Disruption: Taking Nicotinamide Adenine Dinucleotide boosters late in the day may cause difficulty sleeping due to their ability to increase cellular energy.
If you are pregnant, breastfeeding, taking medications or suffer from chronic illness, consult a healthcare practitioner before introducing NAD+ supplements to your routine.
