  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.

Follow the shopper-submitted screenshots below to spot the Tru Niagen promo box and apply your code. Miss a step and even a working code does nothing, so the agents mapped every one for you.

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.

How We Verify Tru Niagen Codes

Nothing goes up here on trust. A Tru Niagen code is collected, applied to a real truniagen.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.

Help Other Tru Niagen Shoppers

Not every Tru Niagen code reaches us from the store. 7 codes on this page were first submitted by shoppers. Wherever a code comes from, it still has to pass the same cart test before it goes up here.

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.
