Is The NAD the same as NAD+ 4u?

No. They are separate brands. The NAD sells one focused kit: a freeze-dried 1000mg vial with a reusable metal auto-injector, third-party tested to ≥99% with the certificate in every box.

Does The NAD publish a certificate of analysis?

Yes. The Certificate of Analysis for your batch is included in the box. NAD+ 4u states its products are third-party tested and GMP-certified, but does not provide a certificate on its site.

The NAD's NAD+ is made in the UK. NAD+ 4u states its products are made in certified medical-grade facilities, but does not state a UK location.

How does The NAD arrive?

Freeze-dried in a sealed vial, packed cold and shipped tracked from the UK, with same-day dispatch on orders before 3pm and a signature on delivery.

The NAD vs NAD+ 4u

The two, side by side.

Both are 1000mg at-home NAD+ kits. Where NAD+ 4u's site does not state a detail, that is what the table says.

NAD+ 4u details from nadplus4u.com, August 2026. This compares how NAD+ is delivered, not what it does. NAD+ is sold as a food supplement.

Which suits you

Here is the honest split.

NAD+ 4u may suit you if
you want a wider range to choose from, including a subcutaneous option and an oral NMN and glutathione supplement.
The NAD may suit you if
you want a single, considered kit with the batch Certificate of Analysis in every box, and NAD+ that states it is made in the UK.
