Contact Metabolic Guide
We're a small team of real humans — we read every message.
We don't have a customer support line for product brands. We're an independent editorial site. If you have a question about a Lumen device or any other product we've reviewed, please reach out to the brand directly. For everything else, we'd love to hear from you.
