We will not add undisclosed merchant charges to an accepted purchase.

If Zervelli® offers any product or service on a recurring basis, the applicable recurring price, billing frequency, delivery frequency, renewal terms and cancellation method will be disclosed before enrollment as required by law.

If shipment cannot occur within a promised period, we will provide any notice, cancellation option or refund required by applicable law.

Tracking is provided where supported by the selected carrier or shipping method.

That policy explains applicable return eligibility, return procedures, refund methods, exclusions and any commercial return period currently offered.

Contact customer support before mailing a return so that we can provide the correct return destination and handling instructions.

Because dietary supplements are consumable products, return eligibility may vary depending on product condition and applicable law.

Opened, consumed, partially used or tamper-evident products may be subject to different return handling compared with unopened products.

A product that is defective, damaged in transit, materially misdescribed or otherwise subject to mandatory consumer remedies will be handled in accordance with applicable law.

By voluntarily submitting content for public display, you grant us a non-exclusive, worldwide, royalty-free permission to host, display and use that content in connection with the Site and Zervelli® marketing, subject to applicable privacy, intellectual-property and advertising laws.

Private customer-service communications are not automatically treated as permission to publish a testimonial.

Customer reviews reflect individual customer experiences.

Experiences with dietary supplements may vary depending on individual diet, lifestyle, health status, consistency of use and other personal factors.

A review or testimonial does not guarantee that another customer will experience the same result.

Reviews do not replace product labels, Supplement Facts, warnings, suggested-use instructions or advice from a qualified healthcare professional.

We will not knowingly misrepresent a customer review or conceal incentives or material relationships where disclosure is required.

Reviews submitted by customers should reflect genuine experiences.

Discount codes, bundles, free gifts, limited-time discounts, free-shipping offers or other promotions may have additional terms displayed with the offer.

Zervelli® dietary supplements are intended to complement a balanced diet and healthy lifestyle and are not substitutes for individualized medical care.

Individual responses to dietary supplements may vary according to factors including nutrition, lifestyle, age, health status, medication use and individual physiology.

Except where lawfully and expressly stated, Zervelli® products are not intended to diagnose, treat, cure or prevent disease.

Final product ingredients, serving sizes, Supplement Facts, suggested use and warnings should be reviewed on the applicable product page and physical packaging received with the order.

Nothing in these Terms excludes or limits liability where exclusion or limitation would be unlawful.

This includes liability for fraud, non-excludable liability for death or personal injury caused by negligence, mandatory product liability and other rights that cannot legally be waived.

To the extent legally permitted, we are not liable for indirect losses that were not reasonably foreseeable.

Mandatory consumer remedies remain unaffected.

Where legally permitted, you may be responsible for losses reasonably caused by your intentional unlawful use of the Site or a material violation of these Terms.

You are not required under this clause to compensate us for losses caused by our own negligence, unlawful conduct or breach of mandatory consumer protections.

We may restrict access to Site functionality where reasonably necessary to address fraud, security threats, unlawful conduct or serious violations of these Terms.

Restricting website access does not cancel lawful rights and obligations relating to accepted orders, refunds, returns or statutory remedies.

Events such as severe weather, natural disasters, transport disruption, customs delays, carrier interruptions, network outages, supply interruptions or other circumstances beyond reasonable control may affect performance.

Regulatory or customs restrictions affecting dietary supplements or specific ingredients may also affect international fulfillment.

We will communicate relevant order disruptions and provide cancellation, delivery or refund remedies required by law.

This provision does not remove mandatory legal obligations.

Mandatory consumer rights applicable in your jurisdiction take precedence over conflicting provisions of these Terms.

Depending on applicable law, these may include rights concerning:

• pre-purchase information;
• delivery;
• cancellation;
• defective goods;
• product safety;
• product conformity;
• replacement; and
• refunds.

Any commercial return policy we offer is additional to, and not a substitute for, mandatory statutory rights.

These Terms are governed by the laws of the People's Republic of China to the extent a choice of law is legally permitted.

This choice does not deprive consumers of mandatory protections that apply in their country or region of residence.

This clause does not require consumers to give up access to courts or remedies that cannot lawfully be restricted.

If you have a concern about the Site, a Zervelli® product or an order, contact us at service@zervelli.com so we can try to resolve the matter.

If a dispute remains unresolved, either party may pursue available remedies before a court, regulator or other authority with lawful jurisdiction.

These Terms do not impose mandatory arbitration or a class-action waiver.

If any provision of these Terms is found to be unlawful or unenforceable, it will be limited or severed to the extent required by law.

The remaining provisions will continue to apply where legally permitted.

A delay or failure to enforce a provision does not automatically waive the right to enforce it later.

This clause does not limit mandatory consumer rights.

These Terms, applicable Zervelli® store policies and any terms specifically disclosed for an order govern use of the Service and relevant transactions.

Nothing in these Terms excludes statements, representations or pre-contract information that applicable law makes part of a purchase agreement.

We may update these Terms as our services, products, operations or legal requirements change.

The current update date will appear on this page.

Additional notice will be provided where required by law.

Changes ordinarily apply going forward and do not retroactively remove rights associated with an accepted order unless law permits or requires it.
