As a loyal customer, I placed an order on 08.09.2026 for over £200 which has still not been received, despite them promising on 30.09.2026 that it will be delivered. I have been in touch multiple times since to ask for a refund, but this has gone unanswered. I would NOT order from this company again and have lost complete trust. They are now advertising a buy one get one free sale when they haven't even fulfilled existing orders! I am yet to receive my product or a refund.

Ordered NMN,week later still the same order tracking information awaiting picking ‘,contacted,via email,- no response,then contacted my bank to source funds back.

I placed order in April no money no product scammers.....Do not use or trust this company

Konrad Dabrowski, not competition

Very disappointed with Nadiol.

We bought a bulk order earlier this year, the goods were not in and had to be produced. So we agreed that we would get the goods in March. An employee at Nadiol did not respond to us for several weeks and we agreed to cancel the order because of this. Our money was supposed to be credited in March of 2026, now it is June 9 and we have not received the money yet. We trade as a company called sunne greier in Norway. Now nadiol is blaming the wrong iban number and keeps saying that they will pay. I have asked them to call me and they keep saying that they will pay, but nothing happens. Can anyone help us with how to proceed? I have already spoken to the police in the UK, but decided to withdraw the report when they responded positively and said that they would pay. It was also blamed on a cyber attack. Can anyone help us? It is NOK 17,000,- Thank you very much, greetings from a very disappointed business owner who thought nadiol was a large and reputable company. Jonathan Norway

I made an order on 27 of february on madiol.com. I’ ve bought transrasveratrol. Product never delivered to me…! i send them 5 e-mail s asking for updates.. They didnt reply…never! I wrote in the support chat…more times …They never replied. The tracking service does not work…Strangely they send advertising email s bot don’t reply to my questions about the order. So theyre are able to read them…bot choose to not reply…On 21 of march they send an email claiming the site nadiol has been damaged by hackers so that they were not able to fullfill the orders and promising to fiction all of the orders delayed… nowadays i lost money for nothing .

I have placed an order for more than $300 on Feb 11th on the Nadiol website. I received a welcome email but no order confirmation and never received the products (NR-Cl supplements). I have emailed on several occasions to asks the team to look into this matter and my email keeps being ignored. Mxy account has been debited by the amount of the order and I have sent the proof by email. When trying to reach the team on the messaging feature on the website, my messages are marked as "not seen". If someone from the team could get in touch with me it would be very much appreciated.

I have very bad experience with this company. Beginning of January I ordered 3 products. At the end of the month I still hadn’t received my order and also the tracking on the website did not work. I tried to chat with the company but they didn’t even read my chats and also my emails were left unreplied. Finally I contacted the courier myself and they told me my order was sent back to the company. Via tracking I discovered that they received it the 22nd of January but I did not get any message or refund. I went to their address in London only to find out that that the address on their website is false. This is obviously a scam company. I am a real customer. If wanted proof of order and link of return of my order to NADIOL can be provided. There is also no telephone number to contact them. There is no way to contact hem.

Prompt delivery. Ordered on Tuesday and the order arrived on Thursday. Well packaged can’t fault deliver at all.

I have been using various of their produce since 18 months and am confident about their quality. Only once did I receive a 100 gr bag of NMN powder that look like it wasn’t supposed to look. I immediately emailed Sophie at their customer service who did an excellent diligent follow up and send me a replacement free of charge. The kind of follow up service you like to see when something is wrong

I am afraid this company has no credibility with me, I ordered 2 bottles of NADIOL NR capsules in December 2022, Jan 2023 worth £75. One of the bottles security seal had been tampered with so I emailed the company and sent them photos. I received an automated reply and then my communication was ignored. I tried to recover my money later in the year via my Credit Card company but didn't get back to them in time with the company contact information. The capsules meanwhile expired in April 2023. I still have both bottles unconsumed as proof of purchase. I put the £75 loss down to experience and resolved to not trust this company again. It is infuriating that they started emailing me with offers a year after ignoring my emails for a return and refund of the damaged goods. I doubt any of their positive reviews on Google are genuine. Based on my experience they are scammers. I advise extreme caution in ordering from this company. I would offer a zero star if possible. I can provide evidence of my communication with the company if anyone wants to see proof.

It's still early days and I have no hard evidence but I think I am feeling more energised and have better clarity of thought/brainpower, especially later in the day since starting glutathione. Thanks NADIOL, no issues with subscription, delivery etc to date.

I said that before and I’ll say it again, had some issues with delivery in the past but I’m glad I didn’t stop ordering from NADIOL as everything improved. I’m impressed how everything changed for better. Good work NAD ! Keep it going 😊

Its still early days (week 3) but feeling great and thinking that my Nadiol NMN has something to do with it! I'm taking a number of supplements now, but chose this one as its supposed to complement my NAD+, which I'm very happy with. Time will tell but am happy to recommend now.

It's always a gamble buying pretty expensive products from a company new to you, but last month I bit the bullet. This is my first month and I've just renewed my subscription, which was not an automatic process but an invoice that I had to approve, which I actually appreciated and was pretty easy. As with most supplements it will take some time to know it's efficacy, but I was happy enough with the first month to continue. In fact, my daughter has now started buying from them too.

After doing a lot of research, I decided to buy my supplements from Nadiol as the quality is great. The ordering and subscription process are easy to use and I do not face any issues with the deliveries.

I have to say that I had some problems in the past, but it looks like they have improved a lot.
Smoother, faster, better - that how I'm experiencing it now. Well done Nadiol!!

I am a returning customer and I am very happy with the service and the product. Thanks for the Black Friday discount on my product !

Ordered last night and product was dispatched within 12 hours. Can't wait to try nmn

Absolutely no problems with my order. I had an initial support request which was efficiently resolved. The order arrived in good time, although it could have been a little faster. I contribute the delay to having to deal with my support request. The product is top quality!
