What Is NAD⁺?
_{Understanding the Molecule Powering Your Cells}

You’ve probably heard the buzz around NAD⁺ in the health and longevity space. But what is NAD⁺, and why are so many people searching for ways to restore it through NAD supplements?

This molecule has become a hot topic, not because it's trendy, but because it's essential to how your body functions on a cellular level.

What Is NAD⁺?

NAD⁺ stands for nicotinamide adenine dinucleotide, a coenzyme found in every living cell. It plays a critical role in cellular energy production, helping convert the food you eat into usable energy (ATP). Beyond that, NAD⁺ supports:

• DNA repair
• Mitochondrial health
• Immune regulation
• Cellular resilience under stress

Unfortunately, NAD⁺ levels decline naturally with age, and are also depleted by stress, poor sleep, alcohol, and intense exercise. That’s where NAD⁺ supplementation comes in.

A Brief History of NAD⁺

First identified in 1906, NAD⁺ has been at the center of scientific discovery for over a century. Initially recognized for its role in preventing pellagra, a deficiency disease linked to poor nutrition, researchers soon connected NAD⁺ to the body’s ability to convert food into usable energy. As science progressed, studies began to reveal what NAD does in the body, especially its role in cellular energy production, DNA repair, and cellular defense against aging.

More recent breakthroughs have focused on how NAD supports longevity by activating sirtuins, a family of proteins known to regulate metabolism, inflammation, and the aging process. These findings have positioned NAD⁺ as a critical molecule in the study of anti-aging supplements, metabolic health, and natural ways to support healthy aging.

How to Increase NAD⁺ Naturally
If you're wondering how to increase NAD⁺ naturally, the answer includes a mix of diet, movement, and smart supplementation. While NAD⁺ is naturally found in small amounts in foods like milk, green vegetables, and whole grains, these sources are not enough to replace the NAD⁺ lost through aging.That’s where NAD⁺ precursors come in. Supplements containing nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) provide the building blocks your body needs to create more NAD⁺ internally.

Clinical studies have shown the effectiveness of these strategies:
• NR supplementation can raise NAD⁺ levels by up to 40% in 8 weeks
• NMN supplementation delivers comparable results, typically within 10 to 12 weeks
• Exercise also helps preserve NAD⁺ levels, although the benefits are mostly limited to muscle tissue.

If you're looking for natural ways to boost NAD⁺ levels, combining regular physical activity with a high-quality NAD supplement can be one of the most effective approaches.

Why You Want More NAD⁺
Low NAD⁺ levels can affect your energy, aging, and how well your cells function. If you’ve been feeling off, NAD⁺ may be part of the reason.Common signs of low NAD⁺ include:
• Fatigue and poor energy metabolism
• Inflammation and oxidative stress
• Impaired cellular repair
• Accelerated agingBoosting NAD⁺

This is why many people are now searching for ways to increase NAD naturally or choosing trusted NAD supplements to support their health at the cellular level.

Supports:
• Mitochondrial function
• Healthy inflammation response
• Longevity gene activation (like SIRT1)
• Resilience against daily stressors

Different Forms of NAD⁺ Supplements

Not all NAD⁺ supplements are created equal. Here’s a quick look at the most common forms:

1. Nicotinamide Riboside (NR)
• A well-researched precursor to NAD⁺
• Easily absorbed and converted into NAD⁺ inside cells
• Often used in clinical trials and trusted brands
• Found in SFH’s new NAD⁺ formula… coming soon!

2. Nicotinamide Mononucleotide (NMN)
• Another popular NAD⁺ precursor
• Slightly different conversion pathway than NR
• More studies still emerging, with promising results

3. Nicotinamide (NAM)
• A cheaper form of vitamin B3
• Converts to NAD⁺ but may inhibit sirtuins (key longevity proteins)
• Less preferred in longevity-focused products

4. Direct NAD⁺ or Liposomal NAD⁺
• Poor oral bioavailability
• Typically used in IV or liposomal forms for specialized applications

Final Thoughts:

NAD⁺ may be a small molecule, but its impact on your health is massive. It plays a central role in cellular energy production, DNA repair, and the body's ability to maintain resilience as you age.

As science continues to uncover how NAD supports healthy aging, one thing is clear: NAD⁺ levels decline with age, but they don’t have to stay low. Thanks to ongoing research and advancements in NAD supplementation, there are now more effective ways than ever to help restore and maintain your body’s natural NAD⁺ levels.

Stay tuned… SFH has something exciting in the works to help you power up from within.
