Is NAD+ the New Collagen? The Anti-Ageing Molecule Everyone’s Talking About

Just when you thought collagen was the holy grail of healthy ageing, a new molecule enters the chat—and completely changes the game. Introducing NAD+ (nicotinamide adenine dinucleotide), a naturally occurring coenzyme that plays a critical role in cellular health, energy metabolism, and DNA repair. It's found in every living cell and is often described as the silent workhorse behind nearly every vital function in the body, from powering mitochondria (your cell's batteries) to facilitating the repair of genetic material. In other words, without NAD+, your cells can’t function.

 Study Finds Way to Reverse Alzheimer’s

The study was based on their previous work, published in Proceeding of the National Academy of Sciences USA, showing that restoring the brain’s NAD+ balance achieved pathological and functional recovery after severe, long-lasting traumatic brain injury. They restored NAD+ balance by administering a now well-characterized pharmacologic agent known as P7C3-A20, developed in the Pieper lab. Remarkably, not only did preserving NAD+ balance protect mice from developing AD, but delayed treatment in mice with advanced disease also enabled the brain to fix the major pathological events caused by the genetic mutations. Moreover, both lines of mice fully recovered cognitive function.

 What Is NAD and What Does the Evidence Actually Say?

A Surge in Hype, A Need for Clarity. From podcasts to IV lounges, NAD is everywhere. Marketed as a breakthrough in anti-aging, energy, and mental clarity, it’s easy to feel like you’re missing out if you’re not hooked up to an NAD drip. But what is NAD, and does science support the claims? It exists in two forms: NAD+ (oxidized) and NADH (reduced). NAD+ is the form most associated with energy production and cellular repair.

Can this new anti-ageing supplement turn back the clock?

Recently, a new molecule has been added to the list of possible anti-ageing drugs: nicotinamide adenine dinucleotide or NAD+ for short. As we age, levels of NAD+ decrease in many tissues of the body. As NAD+ is involved in many important biological processes, it is thought that this decline might contribute to ageing. Research in mice has shown that replenishing NAD+ can improve many elements of ageing, including age-associated weight gain, enhanced physical activity, improved ability of the body to process carbohydrates and fats, and improved eye function.

I Got the NAD+ IV Infusion Drip Beloved by Celebs and Finance Bros

Online (and on reality TV), NAD has been dubbed the fountain of youth—but many people who choose to supplement with it regularly are less interested in the abstract extension of life or suspension of beauty and more focused on health-related goals like boosting immunity so they can better stave off illness (pre-clinical studies have shown that NAD helps prevent or reduce T-cell exhaustion in mice with sepsis), to manage pain or inflammation, to support metabolic health, to avoid weight gain or insulin resistance, and to improve energy and cognitive function (it me!). But though the Biebers make it look easy, NAD—both the various forms it’s offered as and the scientific research around it—is not so straightforward.

NAD+ is hitting the mainstream and skincare brands want in

The IV drip therapy has won over celebrities and intrigued consumers with its promise to naturally slow down ageing.

NAD+ metabolism: pathophysiologic mechanisms and therapeutic potential

Nicotinamide adenine dinucleotide (NAD+) and its metabolites function as critical regulators to maintain physiologic processes, enabling the plastic cells to adapt to environmental changes including nutrient perturbation, genotoxic factors, circadian disorder, infection, inflammation and xenobiotics. These effects are mainly achieved by the driving effect of NAD+ on metabolic pathways as enzyme cofactors transferring hydrogen in oxidation-reduction reactions.

NAD+: The Molecule of Youth? + Factors That Increase It

NAD+ is a coenzyme that activates enzymes that support redox reactions (electron transfer) in the body. These enzymes include Sirtuins, poly-ADP-ribose polymerases (PARPs), and CD38 [1]. These enzymes that use NAD+ also break down NAD+.

NAD⁺ vs. NADH

At the core of the trillions of cells that make up the human body, each choreographing countless processes, sits NAD+ (nicotinamide adenine dinucleotide). This essential cellular molecule is made of the same building blocks as DNA – nucleotides. While DNA is made up of billions of nucleotides, NAD+ is rather small – composed of just two. But size doesn’t matter here – NAD+ serves so many vital functions in the cell that without it we would not survive. NADH is very similar to NAD+, the only difference is a hydride. What’s a hydride? A hydride is a hydrogen atom with an extra electron. That is, a neutrally charged hydrogen atom holding on to a negatively charged electron. This gives hydride an overall negative charge:

Role of NAD+ in regulating cellular and metabolic signaling pathways

Cellular NAD+ depletion is associated with compromised adaptive cellular stress responses, impaired neuronal plasticity, impaired DNA repair, and cellular senescence. Increasing evidence has shown the efficacy of boosting NAD+ levels using NAD+ precursors in various diseases. This review provides a comprehensive understanding into the role of NAD+ in aging and other pathologies and discusses potential therapeutic targets.

Role of Nicotinamide Adenine Dinucleotide and Related Precursors as Therapeutic Targets for Age-Related Degenerative Diseases...

Nicotinamide adenine dinucleotide (NAD+) is an essential pyridine nucleotide that serves as an essential cofactor and substrate for a number of critical cellular processes involved in oxidative phosphorylation and ATP production, DNA repair, epigenetically modulated gene expression, intracellular calcium signaling, and immunological functions.

The Potential Niacinamide Benefits You Should Know About

Niacinamide sounds like a beauty brand’s chemistry-lab invention (just us?), but the increasingly popular skin-care ingredient is actually just a form of vitamin B3. Niacinamide benefits on the other hand? Not so ordinary: They include potentially improving all kinds of skin concerns, from acne to hyperpigmentation to signs of aging. You might see niacinamide pop up in a topical product and in supplement form (we’ll explain the differences between the two and any potential side effects below) and wonder which one to choose.

The Role of NAD+ in Regenerative Medicine

A wealth of evidence now demonstrates that a decline in cellular nicotinamide adenine dinucleotide (NAD+) is a feature of aging and may play a role in the process. NAD+ plays a pivotal role in cellular metabolism and is a co-substrate for enzymes that play key roles in pathways that modify aging. Thus, interventions that increase NAD+ may slow aspects of the aging trajectory, and there is great interest in methods for cellular NAD+ restoration.

NAD.com

NAD.com is an information hub on nicotinamide adenine dinucleotide (NAD), a coenzyme found in all living cells that is essential for hundreds of critical processes. NAD+, in the form of NADH, is essential for the conversion of food into cellular energy. Although the concentration of this important molecule diminishes as we age, evidence suggests that restoring NAD+ levels can help to prevent many age-related disorders and even lengthen life.
