Last updated: August 12, 2026
Shipping Rates
| Shipping method | Order subtotal | Price |
|---|---|---|
| Free Standard Shipping | $45.00 and above | Free |
| Standard Shipping | Below $45.00 | Calculated at checkout |
Shipping Policy
Free standard shipping applies to orders with a subtotal of at least $45.00. The qualifying subtotal is calculated after discounts and before any applicable taxes. Orders below $45.00 are subject to the shipping rate displayed at checkout.
Once an order is placed, it may be sent immediately to our fulfilment centre for processing. Because fulfilment can begin quickly, we cannot guarantee that an order can be cancelled or that its shipping address can be changed after submission.
If an order has already entered fulfilment or been dispatched, it cannot be cancelled. Please review your order and delivery information carefully before completing checkout.
Orders purchased from another retailer or marketplace are subject to that seller’s shipping and return policies and must be handled directly through that seller.
Customers are responsible for any customs duties, import charges, taxes, or other fees imposed by the destination country or local authorities, unless otherwise stated at checkout.
Delivery Times
Standard domestic delivery generally takes 7–10 business days after dispatch. Delivery estimates are not guarantees and may be affected by holidays, weather, carrier delays, customs processing, high-volume periods, or circumstances outside our reasonable control.
Once an order has been dispatched, carrier tracking will provide the most current delivery information. Naiad is not responsible for delays caused solely by the carrier or for incorrect delivery information provided by the customer. This does not limit any rights that cannot be excluded under applicable law.
Shipping Availability
Available shipping destinations and methods are displayed at checkout. If a destination cannot be selected during checkout, we do not currently ship there.
Return Policy
We offer a 30-day return period, beginning on the date your order is delivered.
To be eligible for a standard return, the product must be unopened, unused, in its original packaging, and accompanied by proof of purchase. Because Naiad products are ingestible dietary supplements, opened or used products cannot be returned for hygiene and safety reasons unless they are defective, damaged, incorrect, or otherwise eligible under applicable law.
Before sending any item back, submit a return request through the return portal or contact form available on our website. Unauthorized returns may not be accepted. Once a return is authorized, it must be received at the designated return address within 14 days of authorization.
The return address provided during authorization may differ from Zenit Group’s business address. Do not send products to the business address unless your return instructions expressly direct you to do so.
Return Shipping and Original Shipping Charges
For standard change-of-mind returns:
-
original shipping and handling charges are non-refundable;
-
return shipping costs are the customer’s responsibility; and
-
refunds are issued only for eligible items successfully received and inspected by our return centre.
If the product is defective, damaged, incorrect, or otherwise subject to a mandatory legal remedy, we will provide the appropriate resolution and cover reasonable return costs where required.
Damaged, Defective, Incorrect, or Missing Items
Inspect your order as soon as it arrives. If an item is defective, damaged, incorrect, or missing, submit a request through our website promptly and preferably within 7 days of delivery. Include your order details and clear photographs of the product, shipping label, and packaging where possible.
Keep the product and all original packaging until the review is complete, as they may be required for assessment or carrier investigation. Once the claim has been evaluated, we may offer a replacement, refund, or other appropriate solution.
Lost or Stolen Packages
If tracking shows no delivery or your package appears lost in transit, submit a request through our website so the shipment can be reviewed with the carrier.
If tracking shows the package as delivered but you cannot locate it, first check the delivery location, household members, neighbours, building reception, and any carrier delivery notice. We may request additional information before determining whether a replacement or refund is available.
Non-Returnable Items
The following items are generally not eligible for a change-of-mind return:
-
opened or used dietary supplements;
-
products without their original packaging;
-
gift cards;
-
personalized or custom products; and
-
items marked as final sale, except where applicable law requires otherwise.
This section does not affect remedies available for defective, damaged, or incorrectly supplied products.
Exchanges
We do not process direct exchanges unless expressly agreed during a support review. The fastest way to obtain another product is generally to return the eligible original item and place a new order after the return is approved.
For a damaged, defective, or incorrect item, provide the reason for the request and photographs where possible. We will determine whether a replacement can be issued without a standard return.
Refunds
We will notify you after the returned item has been received and inspected. If approved, the refund will be issued to the original payment method.
Banks and payment providers may require additional processing time before the refund appears in your account. Any promotional discount applied to the original purchase will be reflected in the refunded amount.

Return requests, shipping claims, and order-related requests must be submitted through the return portal or contact form available on our website.
