Optimum Nutrition UK Reviews 103

Platinum HydroWhey remains one of the highest-quality protein powders I've used.

The biggest advantage is its hydrolyzed whey protein. It digests incredibly fast, making it an excellent choice after intense workouts when rapid protein absorption is important. Unlike many other protein powders, it feels very light on the stomach and doesn't cause bloating or digestive discomfort.

The protein quality is outstanding, with a high protein content per serving and a strong amino acid profile to support muscle recovery and growth. Recovery feels noticeably faster, especially during periods of high training volume.

Mixability is another major strength. It dissolves easily in water with no clumps, and the texture is smooth compared to many whey isolates I've tried. The taste is also surprisingly good for a hydrolyzed protein, which is often difficult to achieve.

While it is more expensive than standard whey concentrates or isolates, the quality, digestion speed, and overall performance make it worth the investment for serious athletes and fitness enthusiasts.

Highly recommended for anyone looking for a premium post-workout protein supplement.

Is always a pleasure to have good deals so thank you

I have been a long term customer of Optimum Nutrition. Their products are fantastic and I have never had any issues with them. The delivery has always been efficient and products arrive in a timely and safe manner.

Great product, great price, delivered quickly 👍🏻

Great service, great products & full selection of training supplements

Really liked the Milk Chocolate flavour — tastes good and mixes well. What I liked most is that it feels very light compared to many other protein powders, so it’s been easy to include in my daily routine. Overall, a very convenient protein option.

Good quality protein. Extreme milk chocolate flavour is really good 😊

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.
