What is NAD?

Nicotinamide adenine dinucleotide (NAD) is a molecule that our bodies produce naturally. NAD fuels our cells’ energy production and muscle growth. It also activates vital enzymes that do everything from repair DNA and extend cell life to regulate immune function.

How does NAD work?

NAD is both a substrate and a coenzyme. This means that it both feeds (substrate) and activates (coenzyme) enzymes that our bodies need to function and stay healthy.

Why is cellular health important?

Every structure of your body, from your skin to your heart, is made of cells. Cells also perform important functions within your body. They do everything from fight infection and heal wounds to regulate metabolism and aging. Cell damage can occur at random or through exposure to free radicals or infection, and this damage may accelerate aging or result in chronic disease. When you protect your cells, you protect the health of your whole body.

Why should I take NAD+? (benefits)

NAD molecules are vital for basic body functioning, and improving NAD levels can promote optimal aging and athletic performance. Crystal Star’s NAD+ supports immune system regulation, muscle energy, mitochondria synthesis, DNA repair, healthy cholesterol levels, and protection against free radicals. All of these processes play a role in healthy aging and longevity.

When can I expect to see results from taking NAD+?

Consumers taking a daily dose of two Crystal Star NAD+ capsules can expect to reach sustained optimal NAD levels within 30 days.

What should I expect to feel while taking NAD+?

Because NAD+ works with your body’s own natural processes, everyone’s experience with NAD+ will be different. Some consumers report feeling more energized within a week or two of starting NAD+. That said, Crystal Star NAD+ is not a stimulant and its benefits to your overall health and energy are more often gradual and sustained with daily use.

Is NAD+ safe?

The ingredients in Crystal Star NAD+ have passed extensive toxicology and safety assessments conducted over more than two decades. There are no known side effects to Crystal Star NAD+ when used as directed.

Is NAD+ natural?

Crystal Star NAD+ is composed of natural ingredients that your body routinely (but slowly) synthesizes on its own. By directly providing your body with these ingredients, Crystal Star NAD+ makes it quicker and easier for you to produce your own NAD molecules.

How does Crystal Star’s NAD+ formula differ from Tru Niagen & Elysium formulas?

Crystal Star’s NAD+ uses a unique and proprietary blend of NAD precursors NAM (niacinamide) and Bioenergy Ribose. This blend is designed to support short-term energy as well as long-term health. Crystal Star’s NAD+ formula not only yields a higher concentration and better distribution of NAD compared to the NR (nicotinamide riboside) in Tru Niagen® and Elysium, it also helps your cells make more ATP energy molecules. ATP fuels many cellular processes, including muscle contractions during exercise.
