Yes. Over and above your legal rights, we offer a 30-day money-back guarantee, also called our satisfaction guarantee. If you have given a product a fair try and simply didn't feel a difference, we will give you your money back, with no complicated questions. It even applies if you have opened and used the product.

The guarantee covers your first order of a given product. Some products sit outside it, including all of our tests, Vitamin D, Magnesium and bundles. The Delivery & Returns section on each product page tells you whether it applies.

To use it, email us at support@kalla.com with your order number and the email you used at checkout. In most cases we won't ask you to send anything back. It applies to orders placed on kalla.com, and we may decline it where we have good reason to believe it is being used in bad faith.

Yes. Every EU customer has the right to change their mind, and we have extended that right from the usual 14 days to a full 30 days. It applies to all products except the Microbiome Test, which is made specifically for you and can't be withdrawn once it has been sent.

Your product needs to be in good condition, with the seal and packaging unbroken. To start, use our return form or email support@kalla.com, and our team will reply with a return shipping slip. Please don't send anything back before you hear from us.

We may charge for return shipping, in which case it is deducted from your refund. Once approved, we refund you as quickly as we can. For full details, see our Refund policy.
