EXPOSED: The NAD+ Supplement Scam No One’s Talking About

If you’re taking NAD+ to support healthy aging, boost energy, or protect your brain… there’s something you need to know.

A new report just revealed that half of the most popular NAD+ supplements on Amazon contain little to no actual NAD+.

That’s right—many of the bottles lining virtual shelves might not be doing a thing for your health. And for a supplement that’s already under scrutiny for poor absorption and fragile stability, this should raise serious red flags.

Let’s break it down.

Researchers at SuppCo, a digital health platform that performs independent supplement testing, recently evaluated 10 top-selling NAD+ products purchased anonymously through Amazon.

The results?

• 5 out of 10 supplements contained little or no NAD+—despite what the label claimed.
• Only 4 supplements delivered 95% or more of the amount promised.
• One brand failed its first test and barely passed a second attempt with wildly inconsistent results.

And we’re not just talking about small-time products. These were top-performing NAD+ supplements among SuppCo users—meaning many consumers trusted them.

But as it turns out, trust is not enough.

So how does this happen?

According to SuppCo scientists, there are several key issues at play:

• NAD+ is chemically fragile, easily broken down by heat, moisture, and oxidation.
• Some brands use “liposomal” or complex blends that interfere with accurate testing.
• Others hide behind confusing language like “≥50% active” to technically meet labeling standards… while short-changing the customer.

One common red flag? Exaggerated label doses.

Supplements that passed testing averaged 312 mg per serving. The failures? Over 1,000 mg on average—suggesting some companies may be inflating their numbers to look more effective or appealing.

It’s not just dishonest… it’s dangerous for public trust in natural health.

And because you can’t “feel” NAD+ working, many people have no idea they’re getting ripped off.

So how can you protect yourself?

Here’s what to look for when choosing an NAD+ product:

• Reasonable dosing – Avoid products claiming more than 500 mg per serving.
• Third-party testing – Look for certifications from ISO-accredited labs like UL, NSF, or Eurofins.
• Transparent labeling – Skip proprietary blends and vague “percent active” statements.
• Brand reputation – When available, choose brands with strong TrustScores, GMP compliance, and a track record of clean testing.

NAD+ may be a powerful tool for healthy aging—but only if you’re actually getting what the label promises.

Don’t be fooled by big claims or low prices. If you’re serious about your health, invest in supplements that are third-party tested, transparently labeled, and made by brands you can trust.
