If you’ve been on wellness blogs or scrolling Instagram lately, you’ve probably seen people talking about NAD⁺ like it’s the answer to everything.

I’ll be honest, I was curious, but also a bit skeptical. Is this actually something worth paying attention to, or just another trend that’s everywhere right now?

What Is NAD⁺ Anyway?

The name sounds complicated, but the idea isn’t. NAD⁺ (nicotinamide adenine dinucleotide) is something your body already makes and uses all the time. It’s a coenzyme, basically a helper molecule that supports a lot of important processes in the body. You can think of it as part of what helps your cells keep things running. It plays a role in turning the food you eat into usable energy and supports how your cells carry out their day-to-day functions.

You don’t feel it directly, but your cells rely on it constantly.

So What Happens as We Age?

Here’s the part most of us can relate to. As we get older, NAD⁺ levels in our cells naturally decline. That’s just part of biology. And around the same time, a lot of people start noticing things like lower energy, slower recovery after exercise, more fatigue, changes in sleep or mood, or just a general feeling of not being quite as resilient as before.

Researchers have observed this connection, which is part of why NAD⁺ has become such a talked-about topic. Keeping levels supported may help your cells stay a bit more resilient as you move through different stages of life.

Should Everyone Be Boosting Their NAD⁺?

Not necessarily.

You don’t need to rush out and do anything just because it’s trending. That said, some people do look into supporting their NAD⁺ pathways, especially those dealing with more fatigue as they get older, people who exercise regularly and want better recovery, or anyone juggling a lot of stress and not getting enough sleep. If cellular health and ageing more mindfully is something you’re already thinking about, it’s worth understanding a bit more. The focus really comes back to supporting your body as it is right now, rather than chasing some earlier version of yourself.

Ways People Support NAD⁺ Naturally

The good news is, a lot of what supports NAD⁺ is already part of a solid, balanced lifestyle.

Food is a good place to start. Certain nutrients help your body produce NAD⁺ naturally like niacin (vitamin B3) from whole grains, legumes, and nuts, tryptophan from seeds, turkey, and tofu, and antioxidant-rich foods like berries, leafy greens, and colourful vegetables. Nothing complicated, just consistentcy.

Movement helps too. Moderate physical activity, walking, strength training, yoga, encourages your cells to stay metabolically active, which supports how NAD⁺ is used and recycled in the body.

Sleep matters more than most people give it credit for. Your cells do a lot of their maintenance work overnight, and better sleep supports the kind of metabolic balance that keeps these systems running more smoothly.

And stress is worth taking seriously. Chronic stress puts a real demand on your energy systems. Practices like gentle breathing, time outside, meditation, or even just slowing your pace during the day can help support overall vitality in a way that shows up over time.

What About Supplements?

There are supplements, usually NMN or NR, that aim to support NAD⁺ levels, and some research does suggest they can raise levels in the body. Some people report feeling more energy or resilience when using them. But results vary, and they’re not necessary for everyone.

It’s helpful to keep things in perspective. Supplements are there to support the basics, not replace them. For some people, they may be worth exploring. But they’re not the starting point for most. Looking at your daily habits, your sleep, your stress, your nutrition, tends to go a lot further in the long run.

So Is NAD⁺ Worth Paying Attention To?

NAD⁺ is a real and well‑researched part of how your body functions, particularly around energy and cellular health. And it does shift as we get older, so your curiosity about it makes sense.

The good news is that a lot of the ways to support it are things you’re probably already working on: how you eat, how you move, how you rest, and how you manage stress from day to day. Small, consistent habits tend to support your body in a much more sustainable way than anything quick or trendy.

That said, NAD⁺ isn’t just for anyone. In particular, NAD⁺-boosting supplements or therapies are something to be cautious with in people with active cancer or a significant cancer history. There’s ongoing research, including lab and animal studies, looking at how cancer cells may use NAD⁺ in their own energy and repair processes, even though it’s also essential for healthy cells.

Because of this complexity, many clinicians advise caution with more intensive NAD⁺-boosting approaches, like IV infusions or high-dose supplements, for people with active cancer. For cancer survivors or those at higher risk, it’s generally recommended to have a conversation with an oncologist or qualified healthcare professional before trying anything in this area.

For most healthy people, the safest and most evidence‑backed way to support NAD⁺ is still through lifestyle, sleep, movement, sun exposure, not over‑drinking, and a good diet, rather than jumping straight into trendy NAD⁺ products.

Simply Salt & Soul

The Salt (The Science): NAD⁺ is a coenzyme involved in how your cells produce energy and carry out essential processes over time. Levels tend to decline with age, which may influence how efficiently these systems function. Supporting NAD⁺ through nutrient‑dense foods, regular movement, quality sleep, and stress management helps create a strong foundation. Supplements like NMN or NR may support levels further in some cases, but lifestyle habits remain the most consistent starting point.

The Soul (The Wellness): Noticing that your energy isn’t quite what it used to be, or that recovery takes a little longer, isn’t a sign that something is wrong. It’s a nudge to pay a bit more attention to what you need right now, and to make space for that in your day. Slowing down, supporting your rest, your boundaries, and your nourishment can be just as powerful as anything you could add in, and it often feels a lot more sustainable over time.
