  2. first two weeks of January
    New Year Wellness Event

    Promotional discounts and special bundle offers are launched to support health and fitness resolutions early in the year.

  3. late November
    Cyber Monday Event

    An online-exclusive extension of holiday savings offering special markdowns across core supplement lines.

Before You Buy at Tru Niagen

What shoppers ask most about Tru Niagen.

›Can I combine multiple promo codes on a single order?

Only one promotional code or discount coupon can be applied per checkout session, and codes cannot be stacked with subscription discounts unless explicitly stated in the promotional terms.

›Are there any products excluded from promo code discounts?

Promotional discount codes generally apply to standard foundational products and never apply to Niagen NanoCloud sachets or pre-discounted multi-pack subscription bundles.

›Do you offer price adjustments if an item goes on sale later?

Price adjustments are not offered for past purchases if a product later goes on sale or is featured in a promotional event after your order has already been processed.

›Why is my active promo code being rejected at checkout?

Promo codes may be refused if they have expired, require a specific minimum purchase threshold that has not been met, or conflict with an active subscription item in your cart.

Have a code we missed?

Send it over and the agents will run it through a real truniagen.com cart. If it works, it lands here with the test behind it.

Did a code work for you?

Open any Tru Niagen code above and tell us whether it worked. It takes one tap, no sign-up, and a code that keeps failing gets pulled off the page.
