Shipping methods and rates

Tracking
When your order ships, we'll email you a tracking link.
International shipping
We ship internationally with USPS and DHL Express, with rates shown at checkout. Import duties, taxes and customs fees are set by the destination country, aren't included in our prices, and are paid by the customer. Please check that supplements can be imported into your country before ordering. If customs holds, refuses or destroys a package, we can't refund it unless the products are returned to us.
Shipping address
Please double-check your address at checkout. We aren't responsible for orders shipped to an incorrect address entered at checkout. If you spot a mistake, email us right away and we'll fix it if the order hasn't shipped. If a package is returned to us because of an address error, reshipping may carry a new shipping charge.
Lost, stolen or delayed packages
Carrier delays are sometimes outside our control. If your tracking hasn't updated in 7 days, or it shows delivered but you can't find the package, check with neighbors and your local carrier, then email us within 14 days of the expected delivery date. We'll work with the carrier and, where appropriate, send a replacement or refund.
Damaged in transit
See Returns & Refunds. Report damage within 10 days of delivery with photos and we'll make it right.
