More and more wellness conversations mention NAD+<\/strong>: on social media, in \u201canti-aging\u201d treatments, in supplements. As almost always happens when something becomes trendy, promises abound. Here we explain, without jargon, what NAD+ is, what role it plays in your energy and what the evidence says, so you can make an informed decision.<\/p>\n

What NAD+ is in simple terms<\/span><\/h2>\n

NAD+ is a coenzyme<\/strong>: a small molecule that helps enzymes do their work. It's in every cell of your body and takes part in hundreds of reactions. Think of it as a \u201cmessenger\u201d that carries electrons during the reactions your cells use to turn food into usable energy, in the form of a molecule called ATP.<\/p>\n

What it has to do with your energy<\/h2>\n

Most cellular energy is produced in the mitochondria<\/strong>. There, NAD+ helps pass the electrons released when nutrients are \u201cburned\u201d to other molecules that end up generating ATP. Without enough NAD+, that machinery doesn't work well.<\/p>\n

But keep in mind: good cellular function isn't the same as feeling a burst of energy. Coffee removes the sleep signal; cellular energy has to do with underlying processes. If you want to understand the difference, read why hormonal fatigue isn't fixed with more coffee<\/a>.<\/p>\n

Other functions being studied<\/span><\/h2>\n

NAD+ is also \u201cfuel\u201d for proteins involved in DNA repair and gene regulation, known as sirtuins and PARPs. This explains the scientific interest in its relationship with aging. However, most of what's known comes from studies in cells and animals.<\/p>\n

Does it decrease with age?<\/h2>\n

Some studies have found lower NAD+ levels in certain tissues of older people, but the results aren't consistent and the causes are still being investigated. What hasn't been shown is that replenishing it with supplements prevents aging or improves health in healthy people.<\/p>\n

Where your NAD+ comes from<\/span><\/h2>\n

Your body makes it from precursors found in your diet, mainly niacin (vitamin B3)<\/strong> and tryptophan. You'll find them in chicken, turkey, fish, legumes, peanuts, mushrooms and whole grains. A varied diet usually covers these needs. There are also supplements with different precursors; the evidence indicates that some raise blood levels, but how much clinical benefit they provide hasn't yet been shown.<\/p>\n
