NAD+, explained simply

NAD+ is one of those names you see everywhere and rarely see explained. It sounds technical, and it turns up on labels, podcasts and shelves, so it is easy to nod along without knowing what it is. This guide takes a few minutes to explain simply: what NAD+ is, why researchers are curious about it, what we know today and what is still being learned.

What NAD+ is

NAD+ is a small molecule found in every cell of your body. Think of it as a courier. Inside each cell, food is turned into usable energy through a long chain of steps, and NAD+ carries electrons from one step to the next so the chain keeps moving. Without it, the machinery slows.

That is only part of its job. NAD+ also fuels a group of enzymes that look after the daily upkeep of the cell, including DNA repair and the way cells respond to stress. Scientists often describe it as a coenzyme, which just means a helper that other enzymes need in order to do their work.

Your body makes NAD+ itself, mostly by recycling and rebuilding it from smaller pieces that come from food, including forms of vitamin B3. It is not something you have to eat in one piece, which is part of why the topic gets lively.

Why people talk about it with age

Researchers have measured NAD+ in different tissues and found that levels tend to be lower in older people than in younger ones. The drop is not the same everywhere in the body, and it is not yet clear whether the lower levels cause some of the changes we see with age or simply go along with them. One study found that older adults who were physically active had muscle NAD+ levels close to those of young adults, which points to daily habits being part of the picture.

This is the reason NAD+ has become a favorite subject in the science of healthy aging. It sits at the meeting point of energy, cell upkeep and time, and that makes it interesting.

NAD+ itself, and its building blocks

You will hear two other names alongside NAD+: NMN and NR. These are building blocks the body can use to make NAD+. In human trials, taking NMN or NR by mouth has raised the amount of NAD+ measured in blood, although the size of the change depends on the dose, the length of the trial and how NAD+ was measured. In some tissues, such as muscle, the change has been smaller or less consistent.

NAD+ taken as NAD+ is a quieter area of research. Scientists are still working out how much of it reaches the cells that use it, and the research here is at an early stage. That is where the science stands today, and it is why we keep NAD+ and [NMN](/products/nmn) side by side. Some people like to take both, and you are free to choose.

Our NAD+ capsule contains NAD+ at 500 mg per serving, with quercetin and a knotweed extract rich in resveratrol, in a vegetarian capsule.

What the research looks like today

Here is the picture as it stands, in a few short lines.

Most of the encouraging findings come from lab work and from studies in mice. Mice process NAD+ differently from people, so those results are a starting point, not a promise. In humans, trials so far have been small and short, and most of them measured NAD+ levels in blood rather than everyday outcomes like how someone feels or moves. People also vary widely in how they respond.

Researchers describe the field as full of promise and full of open questions, and both are true. That is a good reason to see NAD+ as one part of a well-kept day, next to sleep, movement and good food, instead of a single answer.

How people fit it into a day

Because NAD+ is part of how cells make energy, many people place it in the morning. Our directions are simple: take two capsules once a day, with about 6 oz of water, or as directed by your healthcare professional. Keeping it at the same moment each day matters more than the exact time, so pair it with something you already do, like making your first cup of tea or coffee.

A few things worth knowing. NAD+ is not a stimulant, so there is no buzz to wait for. Many people judge a daily habit over several weeks, by how their days feel overall. If you are pregnant or nursing, under 18, taking medication or have a medical condition, check with your doctor first. Keep it out of reach of children, and store it somewhere cool and dry.

A morning with NAD+

Here is one way a morning can look. A glass of water by the window. Two NAD+ capsules, a [vitamin D3](/products/vitamin-d3-2-000-iu) softgel and a [multivitamin](/products/complete-multivitamin) with breakfast. A small bowl of [ceremonial matcha](/products/ceremonial-matcha-powder) while you plan the day. That is the [Morning Ritual](/pages/morning-ritual) in the house, and you can add the whole set to your cart in one tap, with the saving applied for you.

Questions we hear

Is NAD+ the same as NMN? No. NMN is a building block the body can use to make NAD+. They are related, and they are different ingredients. You can read about both on their product pages.

Can I take NAD+ with coffee or tea? Yes. The directions ask for water with the capsules, and many people take them alongside a morning drink.

How long should I take it? There is no fixed length. Many people keep it as part of their daily ritual and notice how they feel over time. Talk with your doctor if you are unsure.

What does "supports normal cell function" mean? It is a general statement about the role NAD+ plays in the normal workings of cells. It describes the everyday role of NAD+ in the body, not an effect on any health condition.
