We’ve introduced Klarna, a payment method in which you can select from multiple payment options:

Pay Later:
Once your order is confirmed, you'll receive an email with payment instructions within two days from Klarna. You'll then have 30 days to try out your order and only pay when you’re happy. Complete the payment online, at your convenience, with no extra cost. You can pay via credit or debit card in or by logging into

Slice It:
For orders over £35, you can also pay in 3 interest-free instalments, which will allow you to spread the cost of your purchase over 3 equal payments. The payment for each instalment will automatically be collected from the debit or credit card you entered at checkout. Your first instalment will be collected when your order is confirmed by Optimum Nutrition and instalments 2 and 3 are scheduled 30 and 60 days later, respectively. You can always monitor your payments’ schedule in the Klarna app. ​​​​​​​

Credit card 

We use Eurocard/MasterCard SecureCode and Verified by Visa to provide secure, easy transactions. The conditions of the relevant card issuer are applicable and Optimum Nutrition is not part of the relationship between you and the card issuer. During the order process you can opt for payment by credit card and once the payment has been authorised, we’ll send your order immediately.


PayperEmail is a payment method from our payment provider Buckaroo. After a customer service agent has placed an order at your request, you’ll receive a payment request by e-mail. Click on the link and you’ll be redirected to a site where you can pay by credit card or PayPal.

All browsers support SSL and indicate when it’s place. This forms a global standard for secure payment via the internet.

Privacy: the personal data that we request from you is only used to process your order as efficiently as possible. We respect and guarantee your privacy. Under no circumstances will personal data be shared to third parties.
