There are differences between the two most popular NAD+ precursors. Learn the distinctions and what supplementing with each—or both—of them can do for you.

Our body contains trillions of tiny organelles called mitochondria. Mitochondrial function is essential for metabolic health, cellular energy creation, and so much more – here’s why.

Energy homeostasis is a biological process by which our cells balance energy production and expenditure. By energy, we are referring to “cellular energy”, rather than the energy that comes to mind when you think of coffee or energy drinks.

Intermittent fasting is a catch-all term that refers to several eating schedules or patterns with periods of time when you don’t eat or when you reduce the number of calories you’re taking in.

Metabolism is the sum of every chemical reaction in your body. Learn how it works and science-based tips to support it. Metabolism is influenced by a variety of factors, including age, genes, stress levels, sleep, and exercise.

The idea of “boosting” your immune system is an understandably appealing concept—who wouldn’t want a supercharged immune system that goes above and beyond to keep you healthy? The reality, however, is a bit more complex.

The Hayflick Limit suggests that a normal human cell can replicate and divide roughly fifty times before it cannot divide anymore. With cellular senescence, the cell loses the ability to multiply before it reaches that limit.

Autophagy is a process where non-functional or unnecessary cells are removed and recycled so healthy new ones can be built. This “cellular housekeeping” is crucial for immune health and the body’s ability to respond to immune aging.

The immune system consists of two main components—the innate and adaptive immune systems. Think of the innate immune system as the first line of defense—it is nonspecific, and responds in the same way to all pathogens. In contrast to the fast-acting innate immune system, the adaptive immune system takes longer (days to weeks) and is highly targeted.

Omega-3s are extremely important for health: they are necessary for functions from muscle activity to cell growth. They also happen to be one of the two essential fatty acids that aren’t made by the body, and so must be derived from diet. But what are your options if you just don’t get around to doing that?

Everyone knows that DNA is the code that makes you, well, you. But did you know that that code can be used by your body in different ways?

Like many other types of product,epigenetic clocks have varying degrees of accuracy. So how do you know which is the most precise predictor of your biological age?

Why does the label say “Supplement Facts” rather than “Nutrition Facts”? And who decides your recommended daily value of vitamins and minerals, anyway? This primer explains.

These molecules become NAD+ over a series of chemical transformations. Here’s what you need to know about each one.

These two forms of nicotinamide adenine dinucleotide are not exactly the same thing, but they’re chemically similar. It’s complicated. We'll explain.

You’ve heard of this vitamin, and you’ve maybe even taken it, but do you really know what it does? Or where it comes from? Here’s what you need to know.

NR is a highly efficient precursor to NAD+, but its cousin molecule NMN is raising eyebrows as the new kid on the block.

If you zoom in on your body’s most fundamental activity, you’d see cells and molecules hard at work. You might be surprised to learn that some of the most vital players at work are ones you’ve never heard of.

Sirtuins help regulate your cellular health. Here’s what you need to know about how they work, what they can do for your body, and why they rely on NAD+ to function.

This potent polyphenol is promising in scientific research because of its molecular structure and bioavailability. But it might be able to do more than we even know.

Your body acts like an efficient factory to keep the coenzyme NAD+ active throughout your life. Here’s how it works and how you can help the body make more NAD+.

This form of Vitamin B could be the key to restoring NAD+ levels — here’s why.

How fast have you been aging? Let us explain.

NAD+ is essential to the creation of energy in the body and the regulation of pivotal cellular processes. Here’s why it’s so important, how it was discovered, and how you can get more of it.

You’ve probably heard that omega-3s are important for your health, but do you know why? Discover how they’re different from other fats, and how to make sure you're getting the right amount.

The legislation that governs dietary supplements is called DSHEA, and it enumerates nine different categories. This guide explains what they are and what they mean.

This important amino acid has been attracting attention in the science community for its role in overall health.
