The molecule your body naturally produces but which declines with age, and why understanding it could change how you think about energy, recovery and healthy aging.
Today I'm almost 52 years old, yet I have a biological age of just 20, and I attribute a lot of that to NAD optimization.
Many biological changes occur as we age. One of them is a gradual decline in NAD. You can do exactly the same as me to support it, and I'm going to show you how below.
NAD is a very important molecule, because every single cell in your body needs energy, and NAD sits right at the centre of how that energy gets made.
When I coach people over 40, NAD is one of the first things I address, because I regard it as absolutely crucial.
This isn't a small dip. It's a steady, systemic decline that quietly changes how you feel, long before you can put your finger on why. The good news: it's one of the most addressable parts of how we age.
Bringing this into your world, a decline in NAD has an undeniable impact on all areas of your life: how you show up, how hard you can push, and how good you feel doing it.
I was in my early 40s when I discovered NAD and how important it is. NAD naturally declines with age, but there are evidence-based habits I use to support healthy levels. This is my personal approach.
Sleep is one of the most important parts of healthy aging, and preserving your NAD is one of the reasons why. My best advice: a one-hour pre-bed unwind with no digital communication, reading something that helps you switch off. Get to bed relaxed and aim for 8 hours. Mine wasn't good for years, so if this feels hard right now, it's worth the effort.
Resistance training plus cardio helps support NAD by stimulating mitochondrial biogenesis. The message is simple: intense weight training 4 times a week, and cardio regularly, ideally 5–7 times a week. It's exactly why the people who train look younger, healthier, and carry more energy.
Without a doubt, one of the most impactful things you can do is eat all of your food from wholesome, single-ingredient sources. I'm also mindful of sourcing: wild vs farmed salmon, grass-fed vs intensively farmed beef, organic veg. It has a systemic impact on inflammation as we age, which goes hand in hand with healthier NAD status.
NAD supplements can absolutely work, but the majority of them are heavily compromised. Even NAD IVs and injections have limited benefits, and I'd generally avoid most of these interventions because they simply aren't worth the vast sums of money they cost.
The one I do personally use, and would be happy to recommend, is NAD Regen from BioStack. The evidence is overwhelmingly strong, they've built a formidable reputation for putting formula quality first at all costs, and there are thousands of Americans using it every single morning to start their day.
I actually discovered NAD Regen several years ago and, like most things I try, approached it with a healthy degree of skepticism. That skepticism was put to rest very quickly. I'd been given access to all of the R&D and the testing, and then came the impact after 90 days of using it.
Ever since, I've taken NAD Regen every single morning and I carry it with me wherever I travel in the world. It's a non-negotiable for me. As testimony to my belief in it, I send it back home to my parents and give it to my wife too.
Run it for 90 days and you can see a noticeable improvement in cognition along with sustainable energy. You'll also be enhancing your internal biology for the long term, which is the ultimate investment. There's a 100% money-back guarantee as well, so it's totally risk-free. That alone tells you how confident they are in the product.
If you like to investigate the R&D behind ingredients, I recommend this extensive podcast episode with Professor Mike Roberts, the researcher who led the work on the main active NAD compound found in NAD Regen.
Not another single-ingredient precursor. A clinically-studied trio that works on every lever of your NAD economy: produce, recycle and protect.

NAD optimization doesn't happen overnight. You're wasting your money if you use it for 30 days and stop. Give it a proper 90-day run and you can see a noticeable improvement in cognition along with sustainable energy, plus you're enhancing your internal biology for the long term. The 60-day money-back guarantee comfortably covers a real trial.
Even NAD IVs and injections have limited benefits, and they cost vast sums of money. I'd generally avoid most of these interventions because they simply aren't worth it. NAD Regen fits in your bag and your morning: two capsules, done, no needles, no clinic, no drama.
Most NAD supplements are heavily compromised. NAD Regen is the one I use personally. The evidence is overwhelmingly strong, and BioStack has built a formidable reputation for putting formula quality first at all costs. I was given access to all of the R&D and testing before I ever recommended it, and I take it every single morning, everywhere I travel.
Two capsules deliver NAD3® (the engine that raises NAD+ status), Spermidine (Yüth™) for cellular recycling, and Resveratrol (Veri-te™) to activate the sirtuins that put NAD+ to work. It's non-GMO and made in a GMP-certified, FDA-registered facility in the USA. Full supplement facts are on the product page, so always check them if you have specific sensitivities.
