Introduction
Our bodies are marvels of biological engineering, with trillions of cells working in harmony to keep us alive and thriving. But as we age, this intricate machinery begins to slow down.
Our energy levels dip, our skin loses it’s elasticity, and our minds don’t feel as sharp.
The culprit behind many of these age-related changes? A tiny but mighty molecule called NAD+.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of our bodies. It plays a crucial role in hundreds of metabolic processes, acting as a key player in cellular energy production, DNA repair, and gene expression.
But here’s what’s interesting – our NAD+ levels naturally decline as we age, potentially contributing to many age-related health issues.
This is where NAD supplements come into the picture. These supplements aim to boost our NAD+ levels, potentially reversing some of the cellular decline associated with aging.
As someone who’s been fascinated by the science of aging and cellular health for years, I can tell you that the potential of NAD+ supplementation is nothing short of exciting.
The NAD+ Revolution
NAD+ is often described as the cellular currency of energy. It’s involved in converting the food we eat into the energy our cells need to function.
But that’s just the beginning of it’s importance.
NAD+ is also a key player in DNA repair, gene expression, and maintaining our circadian rhythms.
As our NAD+ levels drop with age, these vital processes can slow down or become less effective. This decline is associated with many hallmarks of aging, including decreased energy production, impaired DNA repair, and disrupted cellular signaling.
The most common forms of NAD supplements are nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). These are both precursors to NAD+, meaning our bodies can convert them into NAD+ more efficiently than if we were to supplement with NAD+ directly.
The Science Behind NAD+ Boosters
When we take NAD supplements, our bodies convert them into NAD+. This process is more effective than trying to supplement with NAD+ directly, as our bodies can more easily absorb and use these precursors.
One of the most exciting aspects of NAD+ boosters is their potential impact on sirtuins – a group of proteins often referred to as “longevity genes.” Sirtuins need NAD+ to function, and they play crucial roles in cellular health, stress resistance, and potentially even lifespan extension.
Research in animal models has shown promising results. Studies have demonstrated improvements in mitochondrial function, enhanced DNA repair, and increased cellular energy production with NAD+ supplementation.
These effects have been associated with various health benefits, from improved cognitive function to better cardiovascular health.
For example, a study published in the journal Cell Metabolism found that older mice given NMN showed improvements in metabolism, eye function, and insulin sensitivity. Another study in Nature Communications reported that NR supplementation in mice reduced cognitive decline and enhanced neuroplasticity.
While human studies are still in their early stages, the results so far are encouraging. A small clinical trial published in Nature Communications found that NR supplementation safely increased NAD+ levels in healthy middle-aged and older adults.
Another study in the journal Aging Cell reported improvements in muscle function and body composition in elderly men taking NR.
Implementing NAD+ Supplementation
If you’re considering adding NAD supplements to your health regimen, here’s a step-by-step approach:
1. Consult with a healthcare professional
While NAD supplements are generally considered safe, it’s always best to talk about any new supplement with your doctor, especially if you have existing health conditions or are taking medications. They can help you decide if NAD+ supplementation is right for you and advise on potential interactions with other medications or supplements.
2. Choose your supplement
Decide between NR and NMN. Both have shown promise in research, but NR now has more human studies backing it’s efficacy.

Some popular brands include Tru Niagen for NR and Reus Research NMN Supplement Alternative – Liposomal Nicotinamide Riboside w/Resveratrol & Quercetin “As an Amazon Associate, I earn from qualifying purchases.”
3. Start with a low dose
Begin with the lowest recommended dose on the product label. This allows you to assess your body’s response and minimize potential side effects.
For NR, a typical starting dose is 250-300mg per day.
For NMN, it’s often around 250mg per day.
4. Be consistent
Take your supplement daily, preferably at the same time each day. Consistency is key when it comes to supplementation.
Some people prefer taking their NAD+ supplement in the morning for an energy boost, while others find it helps them sleep better when taken in the evening.
5. Monitor your response
Pay attention to any changes in your energy levels, sleep quality, cognitive function, or overall well-being. Keep a journal to track these changes over time.
Remember that while some people report feeling effects within days, it may take several weeks or even months to notice significant changes.
6. Combine with lifestyle factors
Remember, supplements work best when combined with a healthy lifestyle. Focus on a balanced diet rich in whole foods, regular exercise, stress management techniques like meditation, and good sleep habits.
These factors can all contribute to maintaining healthy NAD+ levels naturally.

Always prioritize a healthy lifestyle alongside supplementation.
Adapting NAD+ Supplementation
NAD+ supplementation isn’t a one-size-fits-all solution. Here are some tips for adapting your approach:
Age Considerations
Older people may benefit from higher doses, as NAD+ levels naturally decline with age. If you’re over 50, you might consider starting at the higher end of the recommended dosage range, but always talk to a healthcare provider first.
Health Goals
Your optimal dose may vary depending on whether you’re focusing on cognitive function, athletic performance, or general anti-aging benefits. For example, if cognitive function is your primary goal, you might mix NAD+ supplementation with other brain-supporting nutrients like omega-3 fatty acids or phosphatidylserine.
Timing
Some people report better results when taking NAD supplements in the morning, while others prefer evening doses. Experiment to find what works best for you.
If you find the supplement energizing, morning dosing might be ideal.
If it seems to improve your sleep, evening dosing could be better.
Cycling
Some experts suggest cycling on and off NAD supplements to prevent potential tolerance. This might involve taking the supplement for a few months, then taking a break before starting again. For example, you might take the supplement for three months, then take a month off.
Combining with Other Supplements
NAD+ supplementation can be combined with other supplements for synergistic effects. For example, resveratrol is often paired with NAD+ precursors as it may enhance sirtuin activity.
Always talk to a healthcare professional before combining supplements.
Building on the Basics
Understanding NAD+ supplementation opens the door to a deeper comprehension of cellular health and aging. It builds on basic nutritional knowledge, extending into the realms of molecular biology and biochemistry.
As you take a closer look into this field, you’ll start to understand how various lifestyle factors – diet, exercise, stress, sleep – all impact your NAD+ levels and overall cellular health. This knowledge can empower you to make more informed decisions about your health and potentially slow down the aging process at a cellular level.
For example, certain dietary choices can naturally support NAD+ levels. Foods rich in niacin (vitamin B3), such as turkey, chicken, peanuts, and mushrooms, provide precursors for NAD+ production.
Intermittent fasting and calorie restriction have also been shown to boost NAD+ levels.
Exercise, particularly high-intensity interval training (HIIT), can increase NAD+ levels and enhance mitochondrial function. On the flip side, chronic stress, poor sleep, and excessive alcohol consumption can reduce NAD+ levels.
By understanding these connections, you can create a holistic approach to cellular health that combines supplementation with lifestyle optimization.
Practical Exercises
To reinforce your understanding and experience the potential benefits of NAD+ supplementation, try these exercises:
NAD+ Tracking
Keep a detailed journal of your energy levels, sleep quality, and cognitive function before starting NAD supplements. Continue this journal for at least a month after starting supplementation to track any changes.
Use a scale of 1-10 for each factor and note any specific observations.
For example:
Day 1 (Pre-supplementation):
- Energy: 6/10 – Felt tired by mid-afternoon
- Sleep: 7/10 – Woke up once during the night
- Cognition: 6/10 – Had some difficulty focusing on complex tasks
Day 30 (Post-supplementation):
- Energy: 8/10 – Sustained energy throughout the day
- Sleep: 8/10 – Slept through the night, woke feeling refreshed
- Cognition: 7/10 – Noticed improved focus and mental clarity
Lifestyle Optimization
Alongside supplementation, apply NAD+-boosting lifestyle changes. This could include intermittent fasting, high-intensity interval training, or increasing your intake of NAD+-rich foods like fish, mushrooms, and whole grains.
Try implementing one new habit each week and note how it affects your overall well-being.
For example:
Week 1: Implement a 16:8 intermittent fasting schedule
Week 2: Add two HIIT workouts to your exercise routine
Week 3: Increase consumption of NAD+-rich foods
Week 4: Improve sleep hygiene by establishing a consistent bedtime routine
Supplement Comparison
If you’re feeling adventurous and your healthcare provider approves, try alternating between NR and NMN supplements (not at the same time) to see if you notice any differences in effects. Spend at least a month on each supplement and keep detailed notes on your experiences.
Stress Test
Before and after a period of NAD+ supplementation, put yourself through a cognitive or physical stress test to see if you notice any improvements in performance or recovery. This could be a timed puzzle, a memory test, or a specific workout routine.
Record your performance and how you feel during and after the test.
For a cognitive test, you might try a timed Sudoku puzzle or a memory game. For a physical test, you could time how long it takes you to run a specific distance or how many repetitions of a particular exercise you can do before fatigue sets in.
