Hello Cynthia,

thank you for your long-standing loyalty over the past 3 years and for taking the time to share your feedback we truly appreciate it.

We understand your preference for unflavoured products with minimal ingredients. At the same time, we would like to clarify that “natural flavouring” does not mean artificial or synthetic. By definition, natural flavourings are derived from natural sources and are used to improve taste without compromising the overall quality of the product.

Our product development aims to balance natural composition, taste, and customer preferences. While some unflavoured options may no longer be part of our current range, this is mainly based on overall demand and usage trends.

That said, your feedback is absolutely valuable and has been shared with our product team, as it helps us better understand the expectations of customers who prioritize strictly neutral formulations.

Thank you again for your input we take it seriously.

Kind regards,
Your Sunday Naturals Team

Thank you for your review, and we’re very sorry to hear about your experience.

Unfortunately, we have not been able to locate your order with the information currently available. To help us investigate this as quickly as possible, we have sent you a request for additional information via Trustpilot.

We kindly invite you to respond there with the requested details so we can identify your order and clarify the situation regarding the missing items.

Regarding the language of our communication, we also apologize for this inconvenience and will make sure to address it once we are able to access your order.

We remain at your disposal and are committed to resolving this for you as soon as possible.

Dear Mr Byrne,

Thank you for your feedback and for taking the time to share your experience.

For this product, we provide a general recommended intake of one tablet every 20 days. The reason for this is that, due to legal regulations, we are not allowed to recommend more than 1,000 IU of vitamin D per day.

If this recommendation were followed strictly, one bottle would indeed last for a very long time. However, in practice it is not possible to offer products with such an extended best-before date, as the raw materials required are not available on the market with such a long shelf life.

In reality, this product is often used by individuals with a higher vitamin D deficiency. In such cases, the dosage is often increased significantly depending on individual needs and medical advice, for example one capsule per day for a certain period of time. This product is generally designed for such situations.
However, for legal reasons, we are not allowed to explicitly recommend a higher intake.

Of course, we are happy to offer a return of the product, provided that it is still sealed in its original packaging.

If you do not have an increased vitamin D requirement, we recommend choosing a vitamin D3 supplement with a lower IU dosage, which allows for easier and more flexible dosing. You can find an overview of our products here:

In general, we recommend checking your vitamin D levels in advance in order to determine the optimal dosage and duration of intake. Individual advice from your doctor or healthcare practitioner can also be helpful.

Thank you again for your feedback.

Kind regards

Dear Angel,

Thank you for your review and for taking the time to share your experience with us.

We sincerely apologize that your order has not arrived as expected and that you have experienced these unfortunate circumstances. We fully understand how frustrating it must be when a shipment is not delivered despite having paid for shipping.

We will carefully review your case again and immediately initiate a detailed investigation with our shipping provider to clarify the exact delivery status and the return of the parcel.

Please contact our customer service team directly and provide your order number, if you have not already done so. We will prioritize your case and work to find a satisfactory solution as quickly as possible – including a refund or a reshipment should it be confirmed that the parcel could not be delivered.

Once again, we sincerely apologize for the inconvenience caused and thank you for your patience and understanding.

Kind regards,
Your Sunday Natural Team

Dear Customer,

Thank you for your feedback. We sincerely regret that you were dissatisfied with our service.

Please note that return options depend on whether the case concerns a complaint (defective or damaged goods) or a return due to dissatisfaction or an incorrect order. Complaints are taken very seriously and reviewed carefully on a case-by-case basis.

In the event of a return due to dissatisfaction or an incorrectly ordered item, returning the goods is generally possible as long as the products are unopened and in their original packaging. Please ensure that the return shipment is sent as an insured parcel with tracking, as we cannot assume liability for items lost in transit without insurance. Kindly note that our returns department does not accept uninsured small parcels. Once the return has been received and processed, the refund will be issued within up to 14 days.

If your case concerns a complaint, we would require further details regarding the specific issue in order to provide an appropriate solution.

As your review does not include detailed information, we kindly ask you to contact our customer service team again and provide your order number along with a brief description of the matter. Our team will be happy to assist you and work toward a fair resolution.

Kind regards,
Your Sunday Natural Team

Dear Ms. Abril,

thank you for your feedback. We sincerely regret that your order did not arrive and understand how frustrating this situation must be — especially after waiting for several weeks.

Please note that in cases where a shipment appears to be lost, an official investigation with the shipping provider must be initiated. Such investigations can take up to 30 days, as the carrier needs to review internal tracking processes and documentation.

That said, we truly regret the inconvenience this has caused you. Although the investigation period has not yet fully elapsed, we have now proactively issued a full refund for your order so that you do not have to wait any longer.

We sincerely apologize for both the loss of your shipment and the delay in communication. This is certainly not the level of service we aim to provide.

If there is anything further we can assist you with, please do not hesitate to contact us directly.

Kind regards,
Your Sunday Natural Team

Dear Zoe,

thank you for your feedback. We are very sorry to hear that you have not yet received an update regarding your order — we understand how frustrating that must feel.

In order to properly check the status for you, we kindly ask you to provide your order number, as we are unfortunately unable to locate your purchase based on this review alone. Please feel free to contact us directly with the details so we can investigate immediately.

Regarding your comment about the postage costs: we understand your concern. We do offer a free shipping threshold, and once the minimum order value is reached, shipping is free of charge. For orders below that threshold, shipping fees apply to cover handling and international postal costs.

We would very much like to clarify this for you and resolve the situation as quickly as possible. Please get in touch with your order details, and we will prioritise your case.

Kind regards,
Sunday Natural Team

Dear Mario,

we are sorry to read that your shopping experience felt frustrating. We fully understand how concerning it is not to see an order confirmation or tracking information.

After reviewing your case, we can confirm that a member of our team responded to you personally yesterday.

It appears that the order was placed using a different email address than the one you later used to contact us. The order confirmation and all related information were automatically sent to the email address provided during checkout. This may explain why you did not initially receive the confirmation in your primary inbox.

We have clarified this directly with you and are, of course, happy to proceed with a refund if that remains your preference.

Please feel free to reach out to us again with the correct order email address so we can assist you immediately.

Kind regards,
Your Sunday Natural Team
