Rythm Health Promo Codes & Coupons February 2026

Enter your friend's referral code (like DEJAN or YY4U46VD for $20 off first orders) in the 'Discount Code' box on the checkout page after adding your test kit to the cart.

Rythm Health's checkout follows standard e-commerce flows: add items like a first test kit, click 'View Basket' or 'Checkout', paste the code, and hit 'Apply'—it validates instantly if you're a new customer. Common scenarios include codes failing if you've shopped before, showing "Code not valid for items in cart" or "First-time purchase only."

To apply a referral code:

1. Log in or proceed as guest
2. Enter code in the discount field before payment
3. Confirm the discount reflects on your subtotal

These $20 referral codes are first-order only, with no specific expiration noted but availability may vary.

Pro tip: Check SimplyCodes for the most current verified Rythm Health promo codes that are tested and working right now.

Referral codes often fail due to being first-purchase only, expired, or invalid for cart items—common errors include "Promo code not valid" or "Only for first-time buyers." Unfortunately, you typically can't retroactively apply a code if forgotten, as discounts lock at checkout completion per Rythm's system.

Users commonly report issues when reusing codes or trying to apply them to subscriptions. If your code isn't working, try these steps:

1. Clear your cart and re-add eligible first kit
2. Verify your code is current and valid
3. Use incognito mode for new user detection
4. Contact Rythm Health support via site chat if problems persist

Limitations: Some codes like DAYLE (10% off) are newer but have specific eligibility requirements.

Pro tip: Always apply codes before completing payment and screenshot your checkout page for support disputes if needed.

No, Rythm Health codes like $20 referral discounts can't stack with others—their system applies only one promo per checkout, prioritizing the first entered.

For first test kits, enter the best available code alone; no bundles or sales automatically combine. When attempting to use multiple codes, you'll likely see a "Code not valid" message.

To maximize your savings:

1. Test the highest value code solo first
2. If it fails, try another code—there's no multi-code field

Restriction: Most promotional codes are first-order only and don't apply to subscriptions.

Pro tip: Compare available codes on SimplyCodes and pick the one with the highest value before checkout to maximize savings without stacking complications.

Referral discounts like $20 off apply only to one-time first kit purchases, not subscriptions.

Codes typically specify "first order" or "first test," with users reporting failures when trying to apply them to recurring plans—often receiving an error message stating "Not valid for subscriptions." Rythm Health offers separate promotions for subscriptions (like 10% off with code RTS) but referral codes are designed for new customer acquisition.

To check eligibility:

1. Select a one-time kit
2. Apply code at checkout
3. Note that subscription options may be presented after purchase but without the referral discount

Limitation: These codes work only with new accounts and expire if not applied to your first purchase.

Pro tip: Purchase a single first kit with a referral code to maximize savings, then consider subscribing later if you're satisfied with the service.
