Setting the Record Straight on NAD+

There's a lot of noise in the wellness space.

As NAD+ has moved from research labs into the broader wellness conversation, it's collected its fair share of skepticism. Some of it is reasonable. Some of it is simply misinformation that's been repeated often enough to feel true.

We believe you deserve the full picture. So let's go through the most common misconceptions — and what the science actually says.

EXPLORE NAD+

Myth Vs. Fact

Myth:

"NAD+ is just a wellness trend. The science isn't there yet."

Fact: NAD+ has been studied in peer-reviewed literature for over 50 years.

Research accelerated significantly in the 2010s when scientists discovered its role in activating sirtuins and PARP enzymes — proteins central to DNA repair and cellular longevity.

A 2013 landmark study in Cell found that restoring NAD+ levels in aging mice reversed several key markers of muscle decline — findings that sparked a wave of human clinical trials now underway globally.

Myth:

"NAD+ supplements don't actually raise NAD+ levels in the body."

Fact: This was an early concern — and clinical research has since addressed it directly.

A randomized, placebo-controlled human trial published in Nature Aging demonstrated that NMN supplementation significantly increased blood NAD+ levels in healthy adults within 10 weeks, with measurable improvements in muscle insulin sensitivity and physical performance.

Bioavailability depends on the form and quality of the supplement — which is precisely why formulation and sourcing matter.

Myth:

"NAD+ is only relevant if you're older or already experiencing health issues."

Fact: NAD+ decline begins earlier than most people realize — measurable decreases have been observed as early as the late 20s.

Supporting NAD+ proactively, before significant depletion occurs, is consistent with a root-cause, preventative approach to wellness.

Research from the Sinclair Lab at Harvard has framed NAD+ as foundational to the kind of cellular maintenance that determines how we age over decades — not just years.
