I’m giving one star
I’m giving one star, which I genuinely feel bad about, as the service was good up until the purchase. However, I’ve had to chase several times for a return label, and the customer service since then has been really disappointing. I expected much better support when trying to arrange a return.
Hopefully, I won’t have to chase them again for my refund.

Seals tampered with on both products in order.
Order received in sealed brown box but both products within box were opened or tampered with. One seal was lifted up and the other seal was pushed through. Consumables are now worthless.
Customer service telephone number refers to email customersupport. Email no longer is used. Needed to submit query on website. After submitting complaint was told ticket has been issued, but there was no ticket reference number. I have received no email to confirm complaint received. Very unhappy and trust impacted.

Poor service
Poor service.
Order delivered with a hole in the bag. Order was sent back and have not heard anything, not a single update since 04.08.26.
I have reached out in 3 separate occasions via email (calls are not being accepted). No response has been given.
It has been 3 weeks and I’m now £170 down with no protein and no refund.

Love it!
Delivery was next day. I ordered on a Friday before 2pm. The whey protein powder is delicious! Ive never had protein drinks before and was worried it would taste a but gross but I could drink this all day haha.
I also ordered the protein shaker which has now been stolen by my partner cause its excellent for on the go!
The website is a bit clunky and it would be great if they had an app. The powder is a bit pricey but its so good . Hoping to see discounts every so often

The lime flavoured plant based clear…
The lime flavoured plant based clear protein is absolutely disgusting, I can't drink it. It's not the lime flavouring that is the issue, it is the underlying flavour of the protein that the lime is trying and failing to disguise.
The company themselves seem to have been fine. Delivery was really quick.

Optimum Nutrition, Great Products at Great Prices
I decided to go direct to Optimum Nutrition when prices elsewhere became too much and to my surprise they have discounts for buying in larger quantities. They have my favourite product which is delicious and has helped me reach and maintain my weight goal for over 5 years. I would highly recommend having a look at their site to see if you can make a saving on something you already buy, without doubt a company who want to look after their customers.

Great product
Great product - for someone who hates the taste of protein powder and protein products, this really does just take like squash. Tastes great, will definitely be buying more of it. Highly recommend to those who are like me and dislike protein shakes etc!

Hi Declan,
Thank you for your lovely feedback.

Delicious!
I am really impressed with the Optimum Nutrition Vanilla High Protein Shake. It has a really nice, smooth taste and a perfectly creamy texture. I love that it is not too sweet, making it very easy to drink. It is an incredibly easy way to hit your daily protein goals on the go. My only wish is that they offered a coffee-flavoured version in this exact ready-to-drink format! Highly recommended

Don't seem to understand the difference between a customer and a supplier
My order was delivered by DPD not to my door as instructed but to the building hallway in central London, where it was naturally immediately stolen. Instead of doing what every single other vendor would have done in this scenario which was to either offer a refund or a replacement, and sort out the delivery problem with DPD, Optimum Nutrition decided to involve me in some convoluted back-office process where my money was held hostage and I had to return documents to take part in some kind of DPD investigation. Despite multiple escalations over a number of weeks the customer service team displayed no understanding of how e-commerce works, nor the difference between a supplier claim which is frankly not my problem and a customer who has done no wrong. I had to involve my credit card company in the end who pushed for a refund on my behalf. After which Optimum Nutrition still had the gall to email me to ask me to withdraw my claim with the credit card company. Truly a surreal experience. A real shame as the product is good - just seem to have no understanding of customer experience.

Hello June,
Thank you for your feedback. We're sincerely sorry to hear about your experience.
Unfortunately, in cases where a parcel is reported as missing after being marked as delivered, we are legally required to conduct a delivery investigation with the courier before we can determine the appropriate next steps. We appreciate that this process can feel burdensome from a customer's perspective, especially when you have done nothing wrong, and we're sorry for the inconvenience this caused.
We understand that the investigation and communication process did not meet your expectations, and we regret the frustration this created. Your feedback regarding the customer experience has been noted and will be shared with the relevant team for review.
We are pleased that the matter has now been resolved and that you have received your refund. We truly value your feedback and are committed to delivering a better experience in the future.
Delayed delivery
I ordered Protein on 21 July with wrong address delivery. Moments after purchase I realised address is wrong. Emailed customer support as they not available via phone. They reassured my parcel will be delivered to correct address but until today 27 July I haven’t received my parcel and DPD mailed me my parcel would be delivered tomorrow in wrong address 😑

After reviewing your case, we can confirm that you contacted our Customer Support Team regarding the incorrect delivery address. The matter was investigated and has since been resolved, with a replacement order sent to the correct address.

Item arrived open
Item arrived open, contacted customer services on 16th July and the response is not solving the problem. I want to RETURN for a replacement or refund, they are avoiding this. Will never order again and will just change to a different brand of product. Will be contacting my credit card provider for a chargeback
