NAD+: Frequently Asked Questions

Who has the best NAD+?

In our 2026 audit, Modern Aminos is listed first for NAD+: its certificate for NAD+ scores 9.5/10 on our lab rule, and its published vendor score is 7.88/10. The full ordered table is on this page.

What is the cheapest NAD+ per mg?

The lowest recorded price per milligram for NAD+ in our audit is the "Best $/mg" figure at the top of this page, and every carrier's price per mg is in the table. Cheapest is not the same as best: the table is ordered by certificate and vendor score, not by price.

How do you rate NAD+ vendors?

Ordered by the lab-rule score of each vendor's certificate for this product (out of 10), then by the vendor's published score, then alphabetically. The certificate score is the same lab rule that builds each vendor's lab sub-score, applied to that vendor's certificate for NAD+; the vendor score is the published overall score. Price per mg is shown but does not change the order. See our methodology for the lab rule.
