Optimum Nutrition UK Reviews 

Customer service was really good. Unfortunately the creatine I got was gritty and the flavour was really not nice (orange). A really expensive mistake to make

Super fast delivery, next day now! Products are great, lots of choices and flavours to choose from. From a leading nutrition and performance brand, I wouldn’t expect anything else, that’s why I don’t go anywhere else. Been using their products for years and have always got great results with superior recovery. Would definitely recommend if your health, wellbeing, body and recovery are your goals.

I’ve been using this product for years but first time I’ve ordered direct from the manufacturer.
I am so impressed. The price was great. Next day delivery was fantastic with an hour allotted delivery slot, super impressive.

Best bang for buck protein and creatine on the market. Always tastes and mixes well.

Platinum range is fantastic.

I use products from this company for a while now and it has never failed the expectations. High quality products delivering a great result if combined with consistent and disciplined training.
Definitely would recommend to anyone who values quality and wants to achieve great results !!!

I bought the 4.5kg of whey protein so I can have it for a long time, and although the protein itself is of great quality (absolutely the best), the packaging just doesn't seal properly.
I tried it in all possible ways, but it's just faulty and will not stick no matter what. It's a pity, because now I have to use other ways to close it and it's definitely not air-tight. You should review your production line because something is not working well.

My order hasn't arrived, I ordered it a week ago!

The product was recommended for its benefits and effectiveness but I have to say why on earth do they need to put an electric blue colouring in it? Adding silly colourings for no benefit? Don’t think I can use it as it contains this which I had no idea about when I purchased.

Second time buying from Optimum Nutrition. Easy ordering from website, fast delivery, quality product.

Easy to navigate, lots of products to chose from, speedy delivery,

Ordered Optimum Nutrition on the evening of Friday 23 January and was really impressed with the speed — shipped on Monday and delivered on Tuesday.

The tub arrived completely sealed and intact, with a great expiry date (almost 2 years). I ordered the Extreme Milk Chocolate flavour: there’s a very slight sweetener taste, but nothing overpowering, and the overall chocolate flavour is actually really good. Mixes well and goes down easily.

Very happy with both the product and the service — would definitely order again.

Loved the Different flavours option and specially the quantity Options .
Recommend 👍

My order, which was scheduled for delivery on Thursday, 22/01/2026, has still not reached me. I would like to highlight the issues I have faced so far:
Thursday:
I was informed that the courier could not deliver my order as “no one was present.” This is incorrect. I live in a student accommodation with a 24/7 reception, and no delivery attempt was made. I also did not receive any call from the delivery agent. I was then notified that my parcel had been redirected to a collection point nearly 50 minutes away from my address. After calling customer support, I was told the parcel would be redelivered on Monday.
Monday:
I waited for the parcel, but instead received another notification asking me to collect it. When I contacted customer support, the call was disconnected after a long wait. I called again, and after another delay I was informed that the delivery driver had not picked up my parcel for redelivery on Monday. I was assured the matter would be escalated and the parcel would arrive on Tuesday (27/01/2026). However, today I received the same collection email once again after which i called the courier again and they said the goods are now being returned to sender.

I tried Optimum nutritions help desk number but the automated voice told me that they have suspended calls and i should email them. I have sent but 2 emails and i have not gotten any response on their end whatsoever.

This experience has caused significant inconvenience and highlights major issues with communication, delivery accuracy, and customer support. I request that this matter be investigated urgently and that my parcel be delivered to my address as originally scheduled.

Taste great and quick shipping!

nice product of a good quality, far too expensive for what it is though and alternatives are about of similar quality for a lower cost.
