Optimum Nutrition Reviews 

Took my money, no evidence of my order either on my profile on their website, or emails. Customer service number doesnt work. Raised two tickets on their website, with no email confirmation or response. I'm going to have to try to get my money back from the credit card company. They are a ghost company DO NOT BUY FROM THEM.

Great company with high quality sport and fitness supplements.
Highly recommend.

They delivered the wrong product and refuse to refund my money with excuses that are ridiculous.

Ive tried 2 products. The gold standard chocolate whey is delicious,better than most milkshakes .I also recently tried platinum pre workout.It has a smooth increase in alertness from the caffeine but the other ingredients really give you focus.I took a clean and press from 56kg to 60kg in a matter of days.

All I could taste was sweetener!!!!!!! it made me feel quite sick The Gold Standard 100% plant protein contains sweeteners.
​The French Vanilla version contains: pea protein, rice protein, natural flavorings, thickener (xanthan gum), cinnamon, sweetener (sucralose)

I have been supplementing my Protien intake for years now since getting my health on track. I drink 1-3 shakes a day depending on if iv hit my macros and how hard iv trained. Over the years iv explored various different Whey based protein powders, and tried many flavours for verity! I came across Optimum Nutrition in my local Hollabd and Barret and was impressed with the nutritional content & quality ingredients list. So though I find it o e of the more expensive brands, unfortunately. I thought I'd invest and give it a try. Wasnt disappointed! It mixes so well, more or less dissolves as soon as it hits the water. No nasty lumps, clumps or gritty 'bits' floating on the top. I was also impressed that it wasnt overly coloured as I find thus so off putting. Noting worse then trying to drink something that's bright pink or fluorescent yellow! No nessascery if the taste and texture is right. Smelt great when mixing and most importantl ....taste is amazing!!!!! In fact iv not looked back and now I'll always have a few tubs on the go. Diwndise is, firstly the price, even on sake it's not much of a saving. Also it's very hard to find certain flavours, fir example Banana and French vanilla (as opposed to vanilla ice cream) in smaller serve tubs or pouches.
And last point is they dont seam to sell single serve sample sachets which I think every brand should offer as standard. As its always a risk and sometimes stops the customer buying a different flavour as if your not keen ( happen to me a few times with other brands) your stuck with a powder you cant use and out of pocket! Nice to have yhr option to 'try before you buy' for a few pounds. I'm sure I'd have tried a few more flavours by now and even ventured into the vegan based powders they have. But hesitant to risk it at that cost!
So please if you are so kind to read this, think about launching some sample sachets, and offering all flavours in the smaller size tubs and pouches! I'd love to try more from you. As I ooend this message with, I get a large measure of my daily protien intake through shakes. So its nice to keep verity in there!
If youd like to send je and samples I'd be more then happy to give them a try and feedback what I think!
I know the garentee us that theyll all mix well and taste great, and hit the nutrition content .....but flavour profiles are personal preferences. So you dont know until you try!
Many thanks

I ordered 2 large containers of creatine for my son and his friend, it came out to 120$ and never received an email about the order being confirmed. I do not trust this website at all and wouldn’t recommend using it.

Bought their protein shakes from local store and complained to them as the shake wasn't a shake even tho it was in date, The shake was set and wouldn't come out of bottle.
i even sent a video of the item and tried to shake it out.

i opened a ticket and was fobbed off that since not bought from there online shop they would not help even tho they make the item.

TOTAL DISGRACE COULDN'T CARE A BIT.

Quick delivery and great quality products, I will be ordering again. Thanks

Okay two quick points here:
1) The product itself is super nice, and the whole nutritional value is great, even the price is nice, fits the quality, no complains about this fr.
2) The taste of a peanut butter chocolate gainer is just terrible, and I didn;t think it would be this bad when I bought it, so minus 1 star for this one. :(

Unreliable website and customer service. Actually the whole company seems to have a serious lack of professionalism nowadays (have been purchasing ON products for more than 10 years). For example, instead of addressing the serious problem of non-authentic products that have flooded the market and contain potentially hazardous substances, the keep changing the packaging between years and countries making impossible to have reliable ways to check if a product is actually authentic! They even removed the special watermarked seal on the packaging, due to "environmental issues" (but kept their humongous plastic containers!). At this point, this company has unfortunatelly lost any trustworthiness...

I was using ON for the first time and ordered 2 large tubs of protein. The order never arrived and despite being in contact with their customer services repeatedly, was constantly fobbed off, and in the end, completely ignored. That was 2 months ago. I had to file a dispute via PayPal to get a refund.
I will NEVER touch this company ever again. Absolutely appalled by their handling of the issue and lack of response.

Never trust regarding refund and returns,i ordered 2 items,from which one item i decided to return straight away soon as i recieved the parcel.
They asked me for the batch number pictures and more of it and product code etc.
Its been 10 days,no response

I placed an order with Optimum Nutrition on 29th November (Order #ONIE82104717), and it still hasn’t been fulfilled. I contacted the support team in early December to address the issue, but there’s been no resolution since then. The lack of communication and action has been extremely disappointing.

As a result, my December training has been seriously impacted, which is unacceptable given the reputation of this brand. I expected much better service and reliability. Very dissatisfied and wouldn’t recommend until they improve their order fulfillment and customer support.

Absolutely shocking experience from this company that I have used many times in the past.
My order was not delivered to me but a doorstep I emailed the company and it has taken 5 days to respond to that email. I phoned and spoke to a male who by the way needs sacking instantly from the company I’ve never spoke to such a rude arrogant individual in all my life that has zero customer service skills. Listen to your recorded phone calls to hear him it’s outrageous that you would employ someone like this as the forefront of your customer services you should be ashamed of yourselves. He told me after his rudeness that he would send me a document to sign by the end of the day that didn’t happen and I had to prize it out of him to even tell me it would be by the end of the day he also hang the phone up without even saying goodbye. Then I called again today and again he was extremely rude on the phone to me I asked for a manager there is not one available but then went on to say I will see if one is available put me on hold for 10 minutes then hang the phone up on me no joke this individual needs some serious training. I run a company and I will definitely be spreading the word about how bad of a company you are and my business will definitely be going elsewhere

Request "1131610 Authentic product"

I sent a request to check the authenticity of the purchased product - I provided all the necessary information, as well as photos. A few days later they responded and asked to provide information and photos... What the hell?! I already sent everything, did they even read my request?! I wrote all the information again and attached all the photos again. A few days later I wrote to them and asked if there was any information on my request. I was told that they were looking into the issue. A few days later I wrote to them and asked if there was any information on my request. Then my request was forwarded to some third-party support in India!!!! Some "Glanbia India"?!! What the hell is this?! My product was not from India, but for the European market, and I bought it not in India, but in Europe, which I have repeatedly written about. In addition, this "Glanbia India" support again asked me to send all the data and photos.... I AM JUST IN SHOCK!!! It feels like no one read my request or looked at the photos, but simply forwarded my messages to whoever they wanted. I have already sent a request for confirmation of authenticity of another ON product, then I got a response in 1 day, and now I have not received a response for a week. What is going on there?!!!

I decided to try Serious Mass to help with my muscle and weight gain goals, but unfortunately, my experience has been less than satisfactory. Despite following the recommended usage, I didn’t notice any significant improvements in my muscle mass or overall weight. Additionally, the taste was not very pleasant, and it often left me feeling bloated. It’s also quite pricey for the results it delivers. Overall, I wouldn’t recommend this product to others looking for effective weight gain supplements.

Additionally, I had a disappointing experience with customer support from FedEx. I missed multiple deliveries and despite reaching out to their support, the issue persisted. It is quite frustrating when errors happen repeatedly even after assurances were given. This kind of customer service is not what I expected.

I ordered from this website and I’m missing 2 items. I just got in touch with customer service which takes ages in responding and they just said that unfortunately they can’t refund because everything is correct. Now, I’m missing the items and the money, don’t buy here

I don't know what's wrong with some people out there with negative reviews of ON but this is the best tasting protein ever. It mixes so well with anything -I'd recommend milk only- and you can feel the pump and great feeling in just 20 minutes if taken by empty stomach. Double rich chocolate is my favorite.

I have been a user of ON for more than a decade. Recently, my authorised dealer didn’t have my usual flavour because of which I thought of placing an order with ON directly. They showed similar pricing and I went ahead and placed my order with them. Few days later I received my order.
I ordered ON’ Whey Protein powder 4.53 Kgs. To my surprise, the bag was taped with Fedex tapes. I didn’t understand why they did so till I pulled out the product to see the protein powder leaking through the tapes. I was devastated as how the manufacturer themselves can dispatch damaged and pilfered products to their customers especially something that has to be consumed!
Since I had received the shipment on Friday, I called them around 4pm and their customer service wasn’t reachable although their website mentions they’re available till 5pm. After repeated attempts, I logged my concern and complaint on their website which said a ticket had been created but no number or reference was provided, neither did I get an email confirmation regarding the same.
Unsatisfied, I got their email address which is nowhere to be found in their contact us page. I sent them an email with photos. Luckily, I got an automated response and email with a reference. It is understood that if they don’t answer phones after 4pm, they won’t respond during weekends. Yesterday, being Monday I expected an email response from them, which I never received. I called them at 2pm yesterday and their team was unreachable.
Luckily, I was able to get hold of a CSA today at 09:55 am. As per him, I shouldn’t be logging complaints on their site (although that is what the website wants you to do), and sending them an email is the correct method (they don’t have their email address in the contact us page - only phone number and form to be filled is available). He didn’t have an answer why they were not reachable on Friday and Monday. He blamed Fedex for damaging the shipment as they are the one’s packing these products. The blasphemy this man said was outrageous. Having worked in the logistics and operations industry for more than a decade, I can personally guarantee that no courier company will pack your products. You have to pack your order in the boxes they give you, print out the AWB issued and handover to their delivery driver. As of now it is under investigation and God knows when will they complete their investigation on the mystery of the damaged order and reply back to me.

Please don’t buy from them directly, they’re can’t even take the onus of their own mistakes.
