What Are NAD and NAC?

By MegaFood Team

Discover MegaFood's Powerful New Formulas for Cellular Health and Vitality

At MegaFood, we’re excited to introduce two new supplements designed to support your body’s resilience and well-being at the cellular level: NAD+ and NAC. Though they may sound similar, NAD and NAC provide distinct benefits that work in different ways to promote your health. Let’s explore what they are, how they differ, and why MegaFood’s formulas stand apart.

What is NAC?

N-acetyl cysteine (NAC) comes from the amino acid L-cysteine, one of the building blocks of proteins. NAC is well known for its role in supporting the production of glutathione, one of the body’s most important antioxidants. Glutathione helps neutralize free radicals that can damage cells and tissues, supporting long-term cellular health and resilience.†

NAC Benefits

  • Supports the production of glutathione, which helps support the liver’s detoxification function and supports a healthy liver†
  • Provides antioxidant activity that helps neutralize free radicals generated by environmental pollutants†
  • Helps support respiratory health and healthy lung function†
  • Supports a healthy inflammation response and helps maintain cellular health†
  • Supports glutathione levels that help maintain a healthy immune response†
  • Antioxidant activity helps support brain health and tissues found in the brain, spinal cord, and nerves†

What is NAD?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell in the body. It is essential for energy production, mitochondrial function, and many cellular processes that contribute to healthy aging.† Our NAD+ formula features nicotinamide riboside (NR) to help replenish NAD levels that naturally decline as we age.

NAD Benefits

  • Supports healthy metabolism and ATP production, your body’s primary source of energy†
  • Helps fuel muscle cells with NAD+ for sustained endurance and strength†
  • Helps support healthy aging by helping to replenish NAD+ levels associated with DNA integrity, cellular repair, and regeneration†
  • Supports healthy metabolism and mitochondrial function†
  • Supports vascular health, cardiovascular function, and healthy blood pressure†
  • Contains resveratrol for antioxidant activity that helps support skin health and renewal†

NAD vs. NAC: How They Differ

While both NAD and NAC play key roles in supporting cellular health, they work through different mechanisms:

  • NAC primarily helps boost antioxidant activity by supporting glutathione production, which aids liver detoxification function, and supports respiratory health.†
  • NAD helps power your body at a cellular level by supporting energy production, mitochondrial function, and cellular processes linked to healthy aging.†
  • Depending on your wellness goals, you might choose one or take both for complementary support.

When to Take NAC and NAD?

For NAC, take one capsule between meals up to three times daily to help maintain steady NAC levels.

For NAD, take two capsules daily to support energy metabolism, healthy aging, and muscle endurance.
