Every code below came directly from the brand for readers of this site. If a code stops working, the page comes down.
I buy from all four myself. I was already a customer and asked each brand for an offer worth passing on.

No end date had been set when these offers were last checked. Partner terms can change, so use each linked page for its dated evidence and confirm the final total before paying.
* The two supplement shops do not apply their code to items already reduced — if something is in a sale, take the sale price.
Why the Coupon Sites Show Bigger Numbers
Coupon aggregators may show offers without merchant-specific terms or a dated check. An advertised figure is not proof that a code applies to this merchant or works at checkout. The useful evidence is the merchant's terms and the final total before payment.
Where These Four Came From
I have been buying from these shops for years, long before any of them knew who I was. MyCore has been my sports nutrition order since I started training properly. HardCore I use for the same reason anyone does — it ships from an Irish warehouse and a return does not cross the water. Nutriest, MyBloods went the same way: customer first, partner afterwards.
That order matters. Each code exists because I asked a shop I already spent money in whether they would do something for people reading this site. The dated terms on each partner page let you check the offer before using it.
Buying protein and weighing up a UK shop against an Irish one? MyProtein alternatives in Ireland covers who ships from where, and when staying put is the better call.
Searching for a shop specifically in Swords or north Dublin? What actually delivers there covers it, including why one well-known Swords name is no longer trading.
How to Tell a Real Code From a Scraped One
- Look for the terms. A real code comes with limits — excludes sale items, minimum spend, one use per customer. Scraped listings never have them.
- Check who is publishing it. A brand's actual partner has a relationship to point at. An aggregator page has a database and an ad slot.
- Do not trust the headline number alone. Confirm that the code is for the correct merchant, read the exclusions and check the final total before paying.
- Watch for the wrong company. Half these pages are built by matching a brand name to whatever is in the database — a bottle brand, a US health service, a different shop with a similar name.
Frequently Asked Questions
Are these Irish supplement discount codes real?
Each was given to this site by the named partner. Its linked page records what it applied to and when those terms were checked. Confirm the final total before paying because partner terms can change.
Why are the discounts smaller than what coupon sites advertise?
The size of an advertised discount does not prove that it applies to the correct merchant or works at checkout. Use the dated partner terms here and confirm the final total before paying.
