- Supervisory authority: ASAE (Portuguese Food and Economic Safety Authority)
Throughout these Terms, “we”, “us” and “Zelthy” mean Huxia, Lda.; “you” and “customer” mean you.
2. Scope and acceptance
These Terms govern access to and use of zelthynutrition.com and the purchase of products through it. By placing an order you confirm that you have read and accepted these Terms, the Returns Policy and the Privacy Policy.
If you are a consumer, that is, if you buy for purposes outside your trade or profession, you have rights granted by law that no clause of these Terms may restrict. Wherever a provision of these Terms is less favourable than the applicable law, the law prevails.
3. Customer account
You may purchase with or without creating an account. If you create one, you are responsible for keeping your credentials secure and for all activity carried out through it. The information you provide must be true, complete and up to date. You may not transfer your account to third parties.
4. Products and information
We aim to present our products accurately. Images are illustrative and colours may vary depending on your screen.
The mandatory information for each food product (legal name, ingredient list, allergens, net quantity, nutritional values, directions for use and warnings) is available on the relevant product page before the purchase is completed, in accordance with Regulation (EU) No 1169/2011.
Food supplements are not a substitute for a varied and balanced diet or a healthy lifestyle. They are not intended to diagnose, treat, cure or prevent any disease. If you are pregnant, breastfeeding, taking medication or have any health condition, consult a healthcare professional before use.
We may change or discontinue products and limit quantities per customer, without this affecting orders already accepted.
5. Orders and formation of the contract
Before completing your order you are shown a summary with the products, the total price, shipping costs and the delivery period, and you are given the opportunity to correct input errors.
Clicking the payment button places you under an obligation to pay. The contract is formed when we send you the order confirmation by e-mail. That confirmation, which constitutes the durable medium required by law, includes the order summary, these Terms, the Returns Policy and the withdrawal form.
We may refuse or cancel an order, stating the reason and refunding in full any amount already paid, in particular in the event of stock shortage, manifest pricing error or reasonable suspicion of fraud.
6. Prices and payment
Prices shown on the website are final prices and include VAT at the applicable statutory rate. Shipping costs are calculated and shown separately before the order is completed.
The price applicable is the one in force when the order is placed, as stated in the confirmation. Prices may change at any time, with no effect on orders already confirmed.
For deliveries outside the European Union, customs duties and import taxes may be payable in the destination country and are borne by you.
We accept the payment methods shown at checkout. Payment is processed by certified providers; we do not store full card details.
Whenever we announce a price reduction, we state the lowest price applied during the 30 days preceding the reduction.
7. Shipping, delivery and passing of risk
We deliver to the regions listed on the website. Delivery times shown are good-faith estimates. Unless otherwise agreed, delivery takes place within a maximum of 30 days from the formation of the contract.
If we fail to deliver within the agreed period, you may set an additional reasonable period; if that period is not met, you may terminate the contract and be refunded in full. Where the agreed period is essential, and this was communicated before purchase, you may terminate immediately.
Risk of loss of or damage to the goods passes to you only when you, or a third party indicated by you other than the carrier, acquires physical possession of the goods.
8. Right of withdrawal
If you are a consumer, you have 14 days to withdraw from the contract without giving any reason. The conditions, the way to exercise it, its effects and the exceptions are set out in our Returns Policy, which forms an integral part of these Terms. The withdrawal form is available on the same page and in the order confirmation.
9. Legal guarantee of conformity
The goods we sell carry the legal guarantee of conformity provided for in Portuguese Decree-Law No 84/2021, for a period of three years from the date of delivery. During the first two years, any lack of conformity that becomes apparent is presumed to have existed at the time of delivery, and it is for us to prove otherwise.
In the event of a lack of conformity you are entitled, free of charge, to have the goods brought into conformity by repair or replacement, to a proportionate reduction in the price, or to termination of the contract, on the terms and in the order provided by law.
These rights do not depend on keeping the original packaging or labels, or on the goods being unused, and they are not affected by our commercial returns policy, which is additional to them.
For food products, the guarantee must be read together with the best-before date shown on the packaging.
To make a claim, contact us at wecare@zelthynutrition.com describing the problem and attaching proof of purchase and, if possible, photographs.
10. Subscriptions
Some products may be purchased on a recurring delivery basis. In that case, before subscribing you are shown the frequency, the amount of each delivery, the minimum term, if any, and the renewal conditions.
You may change, pause or cancel your subscription at any time, free of charge and without giving reasons, through your customer account or the links in the confirmation e-mails. Cancellation takes effect for deliveries not yet processed.
The 14-day right of withdrawal applies to the first delivery, under the Returns Policy.
11. Customer reviews
Reviews published on the website come exclusively from customers who purchased the product from our store. The invitation to review is sent automatically 15 days after the order, only to people who bought, and each review is linked to the corresponding order. That is how we verify it comes from a genuine purchaser. We do not publish reviews from people who have not purchased.
Incentive. We offer a 10% discount on the next order to customers who publish a written review, and 15% to those who include a photograph or video. The incentive depends only on the review being published and on the format chosen, never on its content or on the rating given. A negative review earns exactly the same discount as a positive one.
We do not edit the content of reviews and we do not remove reviews for being unfavourable. We may remove unlawful, offensive, promotional or off-topic content.
By submitting a review you authorise us to publish it on the website and to use it in brand communications, with the attribution you choose. You may request its removal at any time.
12. Intellectual property
The website’s content, including text, images, video, graphics, logos, trade marks and their selection and arrangement, is the property of Huxia, Lda. or its licensors and is protected by Portuguese and European Union copyright and industrial property law.
You may use the website for personal, non-commercial purposes. Any reproduction, distribution, modification or public communication of the content requires our prior written consent.
13. Prohibited uses
You may not use the website for unlawful purposes, or to introduce malicious code, scrape data, circumvent security measures, collect third-party personal data, send unsolicited communications or impersonate another person. We may suspend access in the event of breach.
14. Liability
We are liable for damage we cause by breaching these Terms, under general law.
To the maximum extent permitted by law, we are not liable for loss of profit, loss of opportunity or indirect damage that is not a direct and necessary consequence of the breach.
Nothing in this clause limits or excludes our liability for wilful misconduct or gross negligence, for damage to life, physical integrity or health, for the legal guarantee of conformity, or in any other situation where the law does not allow limitation.
15. Data protection
The processing of your personal data is governed by our Privacy Policy and Cookie Policy. Huxia, Lda. is the data controller.

18. Final provisions
If any clause is held invalid, the remaining clauses remain in force.
These Terms are governed by Portuguese law. If you are a consumer habitually resident in another European Union Member State, this choice does not deprive you of the protection of the mandatory provisions of the law of your country of residence.
Disputes fall within the jurisdiction of the courts of the consumer’s domicile.
