Truly Terrible

Website is truly shocking - badly designed and hard to navigate. Under most product categories in the shop, only one item exists, mainly ones they produce themselves.
Under the heading of 'transparency' are a load of articles written by the owner himself - an MBA, not a PhD...so very questionable if he has a 'team' of science based researchers under him.
Products are very overpriced compared to what can be found on Amazon or Healf, where they offer significant deals on the same products.
Unsurprising that former employees now work together in a different company! Clearly a sinking ship.

Update: having read the response from Ketosource, the only thing I need to amend is that the articles are under the heading 'science' rather than 'transparency'.

As far as I am aware there is no pre-requisite to have purchased from a company to review them, as I am basing my review on my experience on using their website (originally having intended to purchase from them).

I was referred to Ketosource from a couple of sources, one being LMNT customer service who explained their full range could be found there, as well as on Healf, but only the latter stock the brand new flavour - lemonade, and only the latter offer 4 for 3 boxes, just as LMNT do in the US.

The rest of my review still stands. The shop is very poor, why even advertise Ketone Testing as a category when you only stock lancets? Or only a sold out bar under snacks?

Hi Paul, I'm always open to feedback. But most of the claims here are wrong in ways anyone can check in 30 seconds. You probably expect a defensive PR reply. I'd rather just address each point straight.

Shop range: the Ketosource shop isn't designed to be a one-stop buy-everything store. It's focused on Ketosource products plus a small number of trusted partners whose products support keto and fasting lifestyles, like LMNT. That's the point of the shop, not a gap in it.

The transparency page: transparency.ketosource.co isn't an article site. It publishes independent Eurofins (ISO 17025) lab results for every batch I ship. Pass or fail, nothing hidden. Enter the batch code from your bottle to verify exactly what you received.

The science team: I'm the founder with an MBA and have never claimed to be the scientist. Happy to share the team's backgrounds by email if you'd like.

Pricing vs Amazon or Healf: Ketosource products aren't sold on Healf, so you can't get them there. I do sell Ketosource products on Amazon, but not at a cheaper price than the shop. If you actually found the same products cheaper elsewhere, send the link to damienb@ketosource.co and I'll look into it.

The "sinking ship" angle and your actual experience: that framing is a story, not a fact, and I'd rather talk about an order than a rumour. I couldn't find one under "Paul" in my UK records. Send your order reference to damienb@ketosource.co and I'll investigate properly.

Cheers,
Damien

Ridiculous

The worst customer service of any company I have ever experienced - being “provided” almost entirely by AI.

Got a problem and want to live chat? It’s a bot. Email them? Bot. Phone them? Bot.

On the EIGHTH working day after raising an issue which was caused by THEIR system and 6 contact attempts since, they finally emailed me assuring me I was now speaking to a real person.

However, the “real” person sounded suspiciously like ChatGPT:

“I’ve gone right through your account and order history, and I want to start by saying this clearly: you were right to be frustrated. You did everything you could to prevent this, and the delay in getting a proper human response made it worse.

Here’s exactly what’s happened and what I’ve done today: …”

That is EXACTLY how AI speaks. ChatGPT specifically.

Also, what they “did” was exactly the opposite of what I asked for. Asked for a refund, they sent products. They’ve closed the ticket. I’ve emailed them. Just 8 more days to wait for a response …

No doubt they will respond to this review with some AI generated refutation / accusation which I welcome since it’ll make themselves look even worse.

One word for this company? : Lazy!

Why bother to have a business if you can’t be bothered to interact with customers???

Thank you for taking the time to write this. I can hear how frustrating this was, especially given how long you were left waiting and how many times you had to push for clarity.

Your frustration makes complete sense. What you described is not an experience I ever want anyone to have with my company, and the delays and lack of human interaction clearly made an already difficult situation worse.

I’m the person who stepped in to review everything end to end yesterday. I sent you a personal video so you could hear directly from me. This is what I always do when someone has a negative experience with my company - I see it as a sign of respect.

For context on what was happening on our side, not as an excuse but for clarity.

Over a short period, we had a combination of issues surface at once: an unexpected reduction in customer service capacity during our busiest period, parallel testing of an AI assistant in limited support areas, and a new team member onboarding who did not fully follow our internal processes.

That combination created gaps you shouldn't have experienced. That's my responsibility.

You asked for a refund, and got a replacement instead. This was wrong and against our culture. Our team are always taught to listen intently first to understand the customer's need - that's the process. As a result, I personally ensured the refund was completed as requested yesterday in my review.

I also want to acknowledge something important.

While your frustration is entirely valid, some of the assumptions made about us being lazy or uninterested in customers do not reflect how Ketosource operates day to day, its culture or mission.

I would encourage anyone reading this to look at the wider body of reviews to see the full picture, including how we respond when things don’t go to plan.

Here’s what I’m taking away from this, very concretely:

1. Where AI adds clarity and speed for you, we’ll keep it
2. Where AI removes human judgment or care, it will be cut
3. Onboarding is being tightened to ensure our standards are kept when adding new team members

I appreciate you calling this out publicly, even though I’m genuinely sorry it reached this point. Your feedback has already led to changes in how we’re handling support during this transition.

Not great any longer

Ketosource used to be a wonderful company, both to purchase from and to be in contact with. Alas no more it would seem.

It used to feel like the team genuinely cared for clients and it even hosted free online events so you felt part of a community.

Now it's nothing more than a sales driven company that uses AI responses to talk to customers.

I purchase the Pure C8 MCT Oil regularly on Amazon but it's been getting more and more expensive over the years so decided to try Nature's Aid instead. The quality is exactly the same, my blood ketone levels have not changed since using NA, and it's far cheaper!

What is interesting is that when asked, a Ketosource employee stated they buy in the oil from abroad and just bottle and package it. So it's probably the exact same product as Natures Aid!!

Update: the response received from Ketosource is worrying for several reasons.

That it is suggested my experiences in my ketone levels are inaccurate, although I have been testing using a blood monitor for years, I am well versed in the ketogenic diet and MCT Oil, and find it rather insulting my experience should be considered to be wrong.

There is no obligation to respond to a business request for more information - why should I provide them with more personal information? This does not mean the review is not genuine, it simply means I do not wish to provide them with opportunity to contact me directly.

I have purchased products from them, and am simply relaying my experience to others. Should Trustpilot wish to see proof I have purchased from the company I will happily provide it to Trustpilot.

Thank you for your review.

After checking our customer service system, I found no record of a customer named “Hollie.” The reviewer also did not respond to Trustpilot’s “request information” process. These facts, combined with several inaccuracies in the statements made, led me to report this review to Trustpilot for investigation.

To clarify the inaccuracies:

1. Product comparison: Nature’s Aid is a mixed MCT oil (C8 + C10). Multiple repeated scientific studies - and over 10 years of our own experiments with customers - consistently show that mixed MCT oils do not raise ketones to the same extent as pure C8 MCT Oil. The results described in the review are therefore highly unlikely.

2. Employee claim: The review states that “a Ketosource employee” said we simply buy oil abroad and re-bottle it. Our customer service team use a verified knowledge base and would not make such a statement. We have also checked our system and found no record of any such interaction.

3. Customer service & AI: We have always provided personal customer service, with our team handling hundreds of customer queries every week. This hasn't changed. If you read other reviews here you'll see members of our customer service team are often specifically thanked and named by the reviewers. While we also offer an AI chatbot on our website for faster answers, the AI bot itself is programmed to always make clear to customers that they can talk to a human team member at any time.

I and my team are committed to providing accurate information and building genuine relationships with our customers.

This particular review is under investigation for removal based on the lack of evidence as to its genuineness.

Sólo tengo palabras de agradecimiento…

Sólo tengo palabras de agradecimiento para esta empresa. Su buen hacer ante un problema que tuve con uno de sus productos fue de 10/10. Sin yo pedirlo me mandaron para probar otro de sus productos " ketosource" "Puré C8 MCT powder". Con todos los consejos de su nutricionista y no tengo palabras para describir lo bien que me sentó y desterro completamente el dolor de estómago que me producía el aceite.
Si todas las empresas reaccionaran así y creyeran en sus productos como ha demostrado esta empresa, estaríamos en un comercio justo.
Sólo tengo palabras de agradecimiento.

El aceite MCT C8

El aceite MCT C8, funcilna genial, ayuda en el control del apetito y en la pérdida de grasa. Además hay detrás un equipo fantástico que te asesora personalmente cada dia y de forma gratuita. Personalmente lo recomiendo 100%, no compras sólo un producto, sinó todo un apoyo en tu proceso de adelgazamiento, tanto a nivel de información nutricional, como a nivel emocional, animándote cada dia y resolviendo cualquier duda que te surja. Tambien te dan ideas de menús muy interesantes para empezar este nuevo estilo de vida, que no solo mejora tú salud fisica, sinó tambien tu estabilidad emocional, que en mi caso ha sido crucial para mi ansiedad y mala calidad del sueño. Estoy muy agradecida.

I’ve struggled with my weight on/off all my life. Unless someone changes their lifestyle, the long-term benefits are short lived.
Being in touch with Olivia, the nutritional analyst at Ketosource has been beneficial.
I was able to open up and not feel judged, which is so important.
Thank you so much for taking your time to hear my story, Olivia and Ketosource!
Greatly appreciated!

I can't recommend this highly enough!!

Initially the information on the website about the product and its use was very in-depth and gave a lot of detail compared to others so I decided to give it a try. Delivery was quick and again the level of information was better than average including a link to a video explaining everything in simple terms. I had one question and so emailed the help address, I got a response within a few days and the person (Oivia) was really helpful and answered my query. I am 2 weeks in and using the product exactly as directed...I am losing weight (10lbs in 2 weeks), it curbs my hunger, and most importantly I am losing fat from around my stomach area meaning already clothes are fitting better. There is no taste or smell and I am drinking it in either warm water or with black tea/coffee. I have just ordered my second bottle ready for next week and continued success. I can't recommend this enough.

Amazing C8 MCT Oil Product and Service

I purchased pure C8 MCT Oil. The product itself is excellent and arrived quickly. But what I want to tell you is about their product support, which is AMAZING!! Because I am not using the product for a keto diet and weight loss, I had a few detailed and technical questions to make sure I am using the product correctly and getting the maximum benefit from it. Oliva from the product research and development team was OUTSTANDING!!! She answered ALL my many questions promptly and professionally and even provided links for me to do additional research. THIS IS THE CUSTOMER SERVICE ONE SHOULD HAVE FROM ANY COMPANY!! Thank you Olivia and thank you Ketosource!! BTW, I highly recommend the product! :-)

Great product, tastes good, lovely packaging. What was above and beyond with this product is the customer service and support. For anyone who is wanting to lose weight they have supporting information too. I want to say a special thank you to Olivia who went the extra mile with her professional and friendly e-mails.

Comprehensive and tailored support

I was early into a fasting and exercise plan but things were not going exactly as planned which made me really anxious.
I replied to one of their daily emails with a description of my issues.
Olivia got back to me with a comprehensive explanation of what was going on and some helpful guidlines which was greatly reassuring.

I've used Ketosource products and they really want you to succeed in your goals

I've used Ketosource products on and off for a while, originally I came across them via LMNT as they were a UK source for this. Latterly as I've started a gym programme after losing weight with keto I have been using their C8 powder.

I recently found them really useful when troubleshooting some body composition and appetite issues - after a year of successful weight loss I did a personal review, used their online calculation tools and zeroed in on an electrolyte issue. This reversed my issue and I continue to gain strength while managing my weight. A rather lengthy email exchange with their nutritional analyst Olivia clarified my conclusions.

Thanks Ketosource

I ordered LMNT electrolytes from Ketosource. The product arrived on time, as described and the email updates throughout the ordering process were excellent. I have since taken advantage of the discounted price through their easy to manage subscription service so I don’t forget to reorder as these electrolytes have had a huge impact on my energy levels throughout the day. 5 stars from me for both LMNT and Ketosource for offering such a clean and simple way to get hold of a U.S based product that can be hard to come by in the UK. Thanks Ketosource.
