Best ProLon Discount Codes

Enter your discount code in the discount code or gift card field at checkout. Check that the reduction appears before paying, and read the offer conditions for eligible products and any minimum spend. Do not assume that a code will combine with a sale price or subscription offer.

• Compare sale prices: Look at individual product prices before choosing a bundle. Buying separately may suit you better if you only need part of the bundle.
• Choose bundles carefully: Compare the bundle total with the cost of the same products bought individually, rather than judging the saving against products you would not otherwise buy.
• Join the newsletter: Sign up for exclusive promotions and early access. There is no need to assume every newsletter offer includes a discount on your first purchase.
• Check subscription terms: An automatic subscription discount may apply only to the first order and cannot be combined with other discounts. Compare the repeat order price before subscribing.
• Consider delivery costs: Free delivery is available above a minimum spend. Compare the delivery charge with the cost of adding another item rather than spending more simply to reach the threshold.

The European store delivers to the Republic of Ireland and displays prices in euro. Free delivery is available on orders above a minimum spend. Review your order total, including any delivery charge, before paying.

Payment options displayed by the store include Visa, Mastercard, PayPal, Shop Pay, Klarna, Apple Pay and Google Pay.

Kits cannot be returned or exchanged for food safety reasons, so check your selection and quantities before ordering. The returns policy allows cases involving quality concerns, incorrect or missing items, and certain medical adverse events to be reviewed. A refund or replacement is subject to that review rather than a general right to return an unwanted kit.

The Fasting Mimicking Diet kit and one day reset kit are separate products. Bars, shakes, protein products and supplements are also sold in the range, so check the product description rather than treating every item as a complete kit.

Bundles include options such as the Beginner Bundle, Intermittent Fasting Bundle and Longevity Bundle. Compare their listed contents with your intended purchase: a lower bundle price does not make extra products necessary. Check quantities as well as product names when comparing a bundle with individual items.

For an Irish order, use the European store's euro prices throughout your comparison. Keep a single purchase separate from a subscription comparison, since an introductory subscription reduction may not reflect what later orders will cost.

If you are comparing protein products, browse Protein Works alongside the individual bars, shakes and protein products at ProLon. For supplements, you can also check offers from Beeline Healthcare.

The 30% off discount code at the top of this page is ProLon's strongest current offer when you spend €249 or more; for smaller baskets or the popular 5-Day kit, other codes and deals suit you better.

• Spend €249 or more on food and drink or vitamins and supplements: use the 30% off code. On a €249 order, for example, you save €74.70 and pay €174.30.

• Spend €149 to €248: the 25% off code is your best option. On a €199 order, you save €49.75 and pay €149.25. Free shipping also applies at this spend level.

• Spend €99 to €148: use the 20% off code. On a €120 order, for example, you save €24 and pay €96.

• Buying a ProLon 5-Day kit alone: the €30 off sale (reducing it to €169 from €199) beats the 20% codes, as it saves more than 20% would on that item. Our team saw the separate 20% kit code work at checkout, but the sale gives you better value here.

• Spend €199 or more but want a gift with your order: you can pair either the 25% off code or the free shipping threshold with a free L Biome or free fasting shake sachets, depending on which bonus appeals to you.
