Contact us
We are a small team in Grand Rapids, MI, and we would rather hear from you than leave you guessing. Here is how to reach us, and what to expect.
However you reach us, a real person answers, usually within one business day and often the same day. If you are writing about an order, include your order number so we can pull it up quickly. If you are asking about authenticity, tell us where you bought it and what the batch code on your bottle reads, and we will check it against the current 2026 batch right away. We will never ask for your full payment card number by email or phone, so please do not share it with anyone who does.
For media questions or partnership enquiries, use the same support address and put the word media or partnership in the subject line so it reaches the right person. For everything else, the help center answers the most common questions instantly, so it is worth a quick look before you write.
