My experience with the supplements is…

My experience with the supplements is good. I was recommended Sunday Natural by a friend a few years ago, and I have not regretted shopping most of my supplements with them. I am only a bit miffed with the business of recommending a friend. I have done this recently, but I have not had the benefit of receiving the "thank you gift", as I need to spend at least 50 Euros to get it!!! I have contacted Sunday Natural to moan about this, but I have not heard back from them. To date I have bought supplements from them for hundreds of Euros, so, spending an extra 50 Euros is not a big deal. But I found this extremely cheeky of them, to call this a gift. They are acting completely for their own benefit, which I find disgusting.

BIG CONCERN about hygiene seals

BIG CONCERN about hygiene seals

I ordered Sunday Natural Magnesium Malate because of its reputation for purity and quality.

The first bottle arrived with a hygiene seal that had one corner torn off completely, revealing a hole directly into the bottle. The entire seal was wrinkled and slid off easily. It appeared to have been removed and re-glued, with a white pritt-stick like residue. Customer service kindly sent a replacement, but unfortunately the replacement has the same issue: the seal looks manually glued on and slides off with almost no resistance.

I have not used either bottle. I don't consider “high-speed automated production” an acceptable explanation for a hygiene seal that is not securely sealed. A supplement should be protected against contamination, moisture/mould and tampering. When the seal can simply slide off, as a customer I have no way of knowing whether the product was properly sealed under controlled conditions or whether the seal was subsequently reattached.

For a company that places such emphasis on purity and quality, I find this extremely concerning and would expect much better packaging integrity and quality control.

EDIT* I changed my rating from 1 star to 2 because customer service responded quickly and issued a full refund, which I appreciate. I cannot rate it higher at this stage though, as I would need to see the packaging integrity improve before I feel confident using the product. I genuinely hope this is something Sunday Natural addresses, because I would like to be able to trust the product in the future.

Dear Customer,

Thank you very much for taking the time to share your feedback with us.

First and foremost, we want to sincerely apologize for your experience. We completely understand your concerns—when you choose Sunday Natural for high-purity supplements, you rightly expect immaculate packaging and complete peace of mind regarding safety and quality control.

We would like to gently explain what happens during manufacturing: due to the high pressure and speed of our automated production process, the foil seal can occasionally shift, become loose, or stick to the inside of the lid when opened.

We fully appreciate how concerning this looks, but please be assured that your bottles are brand new, unused, and the product itself remains completely safe to consume.

That being said, we know that your confidence in our products is what matters most.

Because your satisfaction and trust mean everything to us, we have issued a full refund for this product so that you can remain a satisfied customer for a long time.

The refunded amount will be visible in your account shortly.

Thank you again for bringing this to our attention. We are actively reviewing this with our quality assurance team to ensure our packaging integrity meets the high standards you expect from us.

Warm regards,

The Sunday Natural Team

No option to leave a review for individual products

The products are probably of good quality, but what bothers me is that there is no option to leave a review for individual products. The overall presentation of the brand also comes across as quite self-congratulatory, which gives me the impression of an arrogant company.

We would like to assure you that we are currently working on improving this aspect of our website and review process. We will also forward your comments to the relevant team, as feedback like yours is very valuable in helping us improve the overall customer experience.

The products are good. The service and the delivery times and prices are horrible. Overall, after having ordered several times for very important amounts, I am not satisfied and will find a more reliable and trustworthy supplier.

Dear Oana,

We are very sorry to hear that you were dissatisfied with our service, delivery times. This is certainly not the experience we want our customers to have.

We would very much like to look into your concerns personally and understand what went wrong with your orders. We will therefore contact you directly by email to discuss your experience and check the status of the relevant orders with you.

Please accept our sincere apologies for the inconvenience, and thank you for bringing this to our attention.

They fixed the issue

Very disappointing. I ordered this product and, while I was away, it was left directly outside my front door in 30+°C heat for just under a week. Normally, I would expect a parcel to be taken to a depot or left with a neighbour, particularly when the product is heat-sensitive.

The packaging itself states that the product should be stored in a **cool, dry place**, so I’m very concerned that being left outside in those temperatures for almost a week may have affected it.

I’ve contacted the company several times, but I’ve repeatedly received what appear to be AI-generated responses telling me to smell the product to check whether it’s okay. I have no idea what it is supposed to smell like, so this isn’t a particularly helpful way of determining whether a heat-sensitive supplement is still safe or effective.

I’m also disappointed that there was no clear warning at the point of ordering about the product being particularly sensitive to heat, or specific delivery instructions to prevent this happening.

I’ve been looking forward to starting the supplement, but I’m not prepared to risk taking it without proper reassurance that it has been stored appropriately. Unfortunately, I’m still waiting for a proper response from the company.

I was told the product was sent out on Thursday 20th but I haven’t had a tracking link through or any update.

Edit: I’ve added some more stars as the replacement did arrive, but communication is very poor, it may be that they are struggling to keep up with growth.

Dear Customer,

We are very sorry that your parcel was left outside in direct sunlight for almost a week and that our previous replies did not provide the clear answer you needed.

According to our Quality Management team, short-term exposure to elevated temperatures during transport is generally harmless for most products. NAC does not require refrigerated delivery and is not classified among our especially temperature-sensitive product groups, such as certain probiotics and Omega-3 products.

However, almost a week in direct sunlight during temperatures above 30°C goes beyond normal short-term transport exposure. As the actual temperature reached inside the parcel is unknown, we cannot conclusively guarantee the original quality and potency of this individual bottle.

You were also right that asking you to assess the product by its smell was insufficient, particularly because NAC naturally has a sulphur-like smell. We have now contacted you directly and offered a free replacement or, if preferred, a refund.

We also apologise that a feedback survey was sent before your enquiry had been properly resolved.

Kind regards,
The Sunday Natural Team

They are superior quality supplements and I have to say that this company does a fine job with research and products and giving good descriptions & pricing .I buy their, coenzyme q10,calcium, potassium, choline and copper.

Product not as described

Product not as described – very disappointing

The product I received does not match the description and ingredient list shown on the website. According to the information provided on the website, the product was not supposed to contain magnesium oxide. However, the label on the product I received clearly lists magnesium oxide as an ingredient.

This is extremely disappointing, especially when purchasing a supplement based on its advertised ingredients. I expect the product I receive to match the information presented on the website.

Unfortunately, after this experience, this is the last time I will order anything from this website. I feel misled and very disappointed with my purchase.

Hello,

Thank you for taking the time to share your feedback. We are very sorry to hear about your experience and understand your disappointment.

The information on our website should of course correspond with the product you receive. We would therefore like to look into the discrepancy regarding magnesium together with you and clarify what happened.

Unfortunately, we were unable to identify your customer account or order based on the information available to us. Could you kindly contact us by email and provide your order number or the email address used for the purchase? This will allow us to locate your order and investigate the matter properly.

Kind regards,

Do your own research on dosage

I am happy with the products I got. The bottles are made of glass, darkened and sturdy, which is especially relevant for the algae oil I also bought. But there are two main reasons I can't put my full trust in this company. First, they sell various all-in-one formulations with 10 to 60 substances in one supplement. The issue is: a lot of the ingredients aren't included in meaningful amounts. There will be an expensive supplement with 25 ingredients listed and a bunch are far below their effective dose. The body can't conjure up health improvements just by being shown an idea of a chemical. You actually need to give it the raw material to work with. That's not harmful but people pay for a product that has Taurine or Citicoline, marketed as " 60+ active ingredients". So making these ingredients part of the marketing seems shady and unnecessarily decreases credence.
Second, I can commend the quality of the bottle and packaging but I can't speak to the quality of what's inside. They do say they aren't allowed to publish the tests of their partner laboratories but there are ways to get external, public validation of your product's safety and quality.

Hello,

Thank you for taking the time to leave us such detailed and differentiated feedback. We are very pleased that you are satisfied with the quality of our packaging, particularly our dark glass bottles, which help protect sensitive ingredients such as algae oil.

We would like to respond to your critical comments in more detail:

1. Dosage in all-in-one complexes

With our multi-complexes, we follow a holistic formulation approach. The aim of these all-in-one products is to provide broad, balanced coverage within the physiological range while also making use of synergistic effects. Some micronutrients serve as important cofactors even in smaller amounts and can support the absorption or function of other key ingredients.

For customers who require individual ingredients such as taurine or citicoline in specific, higher doses, we deliberately offer these as targeted single-ingredient products (pure substances). This allows each customer to decide whether a broad nutritional approach or a more targeted, higher-dose supplementation is more suitable for their individual needs.

2. Quality assurance & laboratory testing

The highest quality and purity are our top priorities. Every batch of our products is thoroughly tested by independent German laboratories accredited according to ISO/IEC 17025. These tests include checks for active ingredient content, heavy metals, microbiological parameters and contaminants.

We take your comment regarding transparency very seriously and are continuously working to make test reports and quality documentation easier and more accessible for our customers.

Thank you again for your honest feedback. Constructive exchanges such as yours help us to continuously improve both our products and the information we provide about them.

Kind regards,
The Sunday Natural Team

Horrible Company

Horrible Company. Scamming the customers.
They pretend to be a UK company by having a website ending with co.uk prices in GBP, but in fact they are based abroad.
The use of AI as customer service is frustrating and patronising.
They falsely promise short delivery.

Hello,

Thank you for sharing your feedback with us. We are sorry to hear that your experience has left you frustrated.

We would like to clarify that Sunday Natural is a German-based company that also operates in the UK. While our UK website displays prices in GBP and is tailored to UK customers, the company itself is based in Germany. We understand that this may not have been sufficiently clear and apologize for any confusion.

Regarding your order, we are pleased to see that one of our colleagues has already been in contact with you and assisted you with your request.

We also appreciate your feedback regarding our customer service. We are continuously working to improve the support experience and take your comments seriously.

Best regards,
Sunday Natural Service

Cholin smells rotten and customer service is not cooperative

We bought 2 bottles of Cholin from Sunday Natural and both smell like rotten eggs. When approaching the customer service, they claimed that this was normal but we bought several bottles of Cholin from 2 other providers since and none had the problem.
When requesting to return our bottles, the customer service was very unclear in their communication but ultimately did not let us return the products as they were opened (though it remains unclear to me how I should inspect the quality of a product in a dark bottle without opening it and the quality did not meet the requirements).

Hello,

We’re sorry that both the product and the communication regarding your complaint left you dissatisfied. We understand why the smell raised concerns, particularly as you had a different experience with similar products from other providers.

We would like to review the product complaint, the batch involved, and the handling of your case once again. Could you please provide us with your order number so that we can locate the correspondence and reassess everything with the relevant team?

I won’t be purchasing any products from this. Company as they are very misleading with their test certificates and cannot show customers what the finished product contains. This is what I received from customer services :

“Please note that we only keep Certificates of Analysis (CoA) for raw materials, not for the finished product. These documents are internal and, unfortunately, cannot be provided individually to customers.”

How can they claim to have tests and expect customers to believe what they claim to have in the product is correct per batch when they can’t even disclose such information?? I shall be purchasing elsewhere

Dear Customer,

Thank you for sharing your feedback.

We sincerely apologize that our previous response left you feeling frustrated and misled.

Purity and transparency are the very foundations of Sunday Natural, and we completely understand why you would want clear proof of what is in your supplements.

To ensure absolute safety, we only work with laboratories meeting the highest international standards (such as ISO 17025, GMP, and FDA registration), including world-renowned partners like Eurofins.

While we strictly test every single batch of raw materials before it is ever used in a finished product, we cannot publish original Certificates of Analysis (CoAs) directly for two main reasons:

First, these internal documents contain sensitive personal data of the laboratory staff who conducted the tests, as well as proprietary testing methods.

Because of this, our partner laboratories strictly prohibit us from publishing or distributing their original files.

Second, manually processing individual certificates for hundreds of raw materials is incredibly labor-intensive.

To keep our premium, pure products fairly priced, we work with certified international laboratories, though we are actively expanding our testing with German partners in response to customer feedback.

Please rest assured that our commitment to clean, safe products is absolute.

We warmly invite you to learn more about our rigorous processes and philosophy in our True Clean Label guide on our website: https://www.sunday.de/true-clean-label-einfuehrung/

We hope this helps clarify our standards and hope to restore your confidence in Sunday Natural.

Best regards,

Your Sunday Natural Team

Wow, Sunday Naturals you have gained a loyal customer <3.

Wow, Sunday Naturals you have gained a loyal customer <3.

Almost all of what I have to say is resoundingly positive, and that should be the takeaway. Amazing product range, fantastic company values, clear and easy to use website, competitive pricing, accurate delivery time estimates, products just as described/pictured, lightning fast customer service (for post-purchase questions)... I'm sure there are more!

In fact, the only aspect in which I would score them less than 10/10 was for the automated AI bot that initially responded to the questions that I sent to customer services. It answered one of my questions incorrectly and luckily I had a sneaking suspicion it was wrong, so when it did connect me to a customer service agent they were able to advise me of the correct information.

Overall I am raving about Sunday Naturals and can't wait for my next order :)
