Optimum Nutrition UK Reviews 

Great service and emails with info so 5/5 for that, only just changed from another brand to this. I will see if it’s all what it’s cracked up to be. I will give it a go for 3 months and see.

Optimum Nutrition Gold Standard Whey is my ultimate go-to protein powder, offering fantastic mixability, rich flavors, and excellent muscle recovery support. Buying directly from the official ON website is a breeze thanks to its clean, highly intuitive layout and fast checkout. The delivery service is exceptionally quick, with orders arriving securely packaged and ahead of schedule. It is a premium product backed by seamless direct shipping, making it highly recommended.

perfect quality and flavour

Terrible delivery! The order is processed by Shopify who only allow a limited number of characters in the address section so I could not advise my full address.

The delivery failed because the driver could probably not find my address.

I called Optimum Nutrition but they do not take calls and only emails. It’s been a few days and still no response to my email.

This product is essential for me in the form of capsules which easier to take great quality thank you .
If you could produce the amino acid LEUCINE EN CAPSULES ON HIS OWN. I WILL BE VERY GRATEFUL.

Used these products for a long time and many different ranges but recent batch of 25g high protein strawberry shakes all had clumps in, must have been a bad batch.

Always on time and excellent product quality

Great products

Optimum Nutrition was 5 stars order tracked, arrived when said and correct, but the delivery firm was awful, left package outside front door in full view of passers by, when behind back gate was stated as drop of place, lucky to be still there when I returned, won't be ordering again as not worth hassle if it went missing. Change your delivery firm and will be used again.

Delivery and production on high quality

Something went wrong when l placed the order l guess "auto fill" put in half post code wrong. That's not ON fault still COULD NOT CALL them, Return email say "not monitored" it gives options for other emails to use of which the Eu one is incorrect! ("server not found") .. Three days later l found them on fb they answered me "a couple of days later.. THANKS GOD FOR THE DELIVERY-MAN Out of the lot (DPD clerks included say we can't change any of tge address must be done by the sender EVEN IF THAT post code was NON existing)) He was the only one who took it on himself look at "safe space" where l put the right post code and deliver.

The best protein supplement out there. Total value for money.

Hands down the best protein I have ever had. The flavor is incredible and it mixes perfectly without any clumping. I’ve finally found my go-to supplement and will definitely be purchasing again. Huge thanks to the team for a top-tier product!

I paid it said dispatched and nothing arrived.

I bought strawberry flavor and i’d say best whey you can get in both terms of quality and taste

Really good taste double chocolat whey protein powder

I have not receive the product or the refund

I’ve tried a few different protein powders but this is without doubt the best tasting one, might be a little bit pricey but more than makes up for it with the unreal taste, Delivery was super quick as well, will definitely be using these from now on.

I didn’t receive the product and can’t contact ON at all. Tried several times, trough phone calls, email, instagram, can’t manage to get a reply.
Had to open a regou d request with my bank!

The tracking id provided for DPD is an old id, to a delivery done in Nov-25. My order was placed in 08 April-26. DPD said there is nothing they can do.

I haven’t had an update since the first email confirming the order.
Had to buy the same product from Amazon to manage to get the product, it arrived the same day.

Now I’m waiting on the bank analysis to get my money back, with all evidence provided that I’ve tried contact with ON multiple times.
