Nuun Promo Codes — 25% Off

The Subscribe & Save program gives you 15% off every monthly order plus free shipping — that's the strongest ongoing saving available. For one-off purchases, bundles offer up to 20% off and 8-packs include 10% off automatically. Joining Nuun+ for free also lowers your free shipping threshold to $30 right away.

Subscribe & Save takes 15% off every monthly order and adds free shipping on top. On a standard 8-pack priced around $53–$56, that's a meaningful reduction every single month, plus you skip the $4.99 standard shipping fee. The savings are applied automatically with no code needed.

Standard shipping is free on orders over $45. Nuun+ Fan members get free shipping on orders over $30. Fanatic and Fantastic tier members get free shipping on all orders with no minimum. Subscription orders also ship free regardless of order size.

Nuun's Refer a Friend program gives your friend $10 off their first order of $30 or more, and you receive $10 for each successful referral. It's a clean deal for both sides, and there's no indication of a cap on how many referrals you can make.

No. Nuun limits orders to a single promo code at a time. It's also worth knowing that 8-packs and bundles are excluded from additional coupon codes — their discounts are already built into the listed price.

First, check that your cart meets any minimum spend requirement. Then confirm the items are eligible — 8-packs, bundles, and subscription orders typically exclude additional codes. Make sure you're only applying one code. If everything looks right and it still won't apply, contact Nuun support directly for help.

It's called Nuun+ and it's free to join. You earn 1 point per $1 spent at the Fan tier, scaling to a 2x multiplier at the Fantastic tier (350 points). Points are redeemable from 80 points ($8 off) up to 400 points ($40 off). Points expire 12 months from the date earned.

Nuun doesn't currently run a dedicated student discount program. The best alternatives for new shoppers are the 20% first-order discount (where eligible) and the free Nuun+ loyalty membership, which starts earning you points and free shipping benefits from your very first purchase.

Nuun does run promotional offers periodically. Fanatic and Fantastic tier Nuun+ members get early access to promotions before they go public, which is a practical reason to build up your points balance. Checking the Nuun website regularly is the most reliable way to catch any limited-time offers.

Nuun offers a 60-day satisfaction guarantee. To request a refund, return, or exchange, contact customer support with your order details — either through the message field on the Nuun website or by emailing info@nuunlife.com. You can also reach the team by phone at 855-426-6886 (Monday–Friday, 8am–5pm PST).
