The only Brainzyme discount code working sitewide right now is RESET10, which auto-applies at checkout for up to 37% off a 6-month Subscribe & Save order, or 10% off a one-time order. Brainzyme is a UK-founded focus supplement brand, and here’s exactly what saves you money today, without the dead codes you’ll find elsewhere.
The One Code That’s Actually Live
RESET10 is the current sitewide code, and you don’t need to type it in anywhere. It’s tied to Brainzyme’s “Back to Focus Sale” (also called The September Reset) and gets applied automatically the moment you land on a product or subscription page, on both Brainzyme’s UK site (GBP) and its US and Canada site (USD). Checking the live checkout on both sites today confirms the same mechanic: the discounted price is already the price you see, not something you unlock by typing a code into a box.
That auto-apply setup is also why so many “enter this code” listings on other coupon sites don’t actually change your total. There’s often nowhere for a manual code to go, because Brainzyme has already baked the discount into the displayed price.
How Much You Actually Save, By Order Length
The percentage scales with how much you commit to upfront. Every tier below reflects what’s live on Brainzyme’s official site as of today.
| Order type | Discount on first order | Discount on recurring orders |
|---|---|---|
| One-time purchase (1-month supply) | 10% off | not applicable |
| Subscribe & Save, 3-month supply | 31% off | 24 to 25% off |
| Subscribe & Save, 6-month supply | 37% off | 33% off |
| Starter Bundle, monthly subscription | 37% off | 33% off |
| Starter Bundle, one-time purchase | 25% off | not applicable |
To put real numbers on it, using Brainzyme FOCUS PRO (the best-selling formula): a one-month, 2-pack supply lists at £29 and comes to £26.10 with RESET10. A 3-month, 6-pack subscription lists at £87, drops to £59.73 on the first order, then renews around £65.25. A 6-month, 12-pack subscription lists at £174, drops to £108.87 on the first order, then renews around £116.58. US and Canadian shoppers see the same tiered percentages in USD, off a $40 one-month base price for FOCUS PRO.
You can cancel or adjust a subscription at any time, so committing to a 6-month supply isn’t a lock-in beyond your next shipment if the formula turns out not to be for you.
Other Ways to Lower the Price Beyond RESET10
A few savings avenues run independently of the current sale:
- Subscribe & Save baseline: once the current promotion ends, subscribing still gets a standing 16% off your first order and every recurring order, per Brainzyme’s own subscription FAQ. Any additional discount code or Medal’s Cash Voucher applies on top of that, not instead of it.
- Medical professional discount: Brainzyme runs a separate exclusive discount for verified medical professionals and health practitioners, accessed through a dedicated application page rather than a public code.
- Free eBook: your first purchase includes a digital Starter Guide eBook at no extra cost, covering dosing and formula selection.
- Free shipping: UK orders ship free; US mainland orders ship free tracked; international orders ship free over £40 (or the local equivalent).
- 365-day returns: every order, including subscriptions, can be returned or exchanged within 365 days, which meaningfully lowers the risk of trying a formula that doesn’t suit you.
- Refer a Friend program: existing customers can apply for Brainzyme’s referral program for ongoing credit, worth checking if you already use the product regularly.
The Codes You’ll See on Other Coupon Sites (and Why We’re Skipping Them)
Search around and you’ll find codes like WELCOME10, WELCOMENEWUSERS, or BRAINZYME10 listed as verified 10% off codes on various coupon aggregators. Cross-checking several of these pages turned up conflicting claims about how many codes are even currently active, and none could be confirmed against Brainzyme’s actual checkout.
In practice, they either duplicate the RESET10 saving already applied automatically, or they no longer work at all. Rather than list codes we can’t verify are live, the more reliable move is to check the price shown at checkout against the figures above. If it doesn’t match, the code, or the listing, is out of date.
Frequently Asked Questions
Does RESET10 work on a one-time purchase, or only on subscriptions?
Both. It applies to whatever is in your cart, one-time or subscription, though subscribing to a longer supply unlocks a bigger percentage than a single order does.
Is there a different code for US or Canadian shoppers?
No separate code is needed. Brainzyme’s US and Canada site runs the identical Back to Focus Sale, with the same auto-applied tiers, priced in USD and CAD instead of GBP.
Can RESET10 be combined with a Medal’s Cash Voucher or another discount code?
According to Brainzyme’s own subscription FAQ, a discount code or Cash Voucher stacks on top of the automatic subscription discount rather than replacing it, though it’s worth confirming the final total in your cart before paying.
What happens to the discount once the current sale ends?
The sitewide “up to 37%” tiers are tied to the current promotional period. The standing Subscribe & Save rate of 16% on first and recurring orders continues afterward regardless.
If you’re buying anyway, a 6-month Subscribe & Save order gets you the deepest discount and the lowest per-serving price, and you’re free to cancel or adjust before the next shipment if it’s not a fit. If you’d rather test one formula first, a one-time order still gets the same RESET10 saving at 10% off, no separate code required. Either way, skip the third-party promo boxes; the price already showing at checkout on Brainzyme’s own site reflects the best offer running today.
