Talk with your doctor before you start. Berberine can interact with some medications, especially those used to manage blood sugar, so bring the bottles to your appointment and let your doctor read the labels. This protocol supports your existing care and never replaces it. Don't change anything you've been prescribed without talking to your doctor first.

Every week, we'll email you a reminder for Dr. Saunders' live webinar. Join in, bring your questions, and ask them as the session goes. Dr. Saunders answers as many as time allows, so if yours doesn't come up one week, you can ask again the next.

No. You pay once and receive your complete twelve week supply. There are no automatic shipments. Applicable shipping and taxes are shown at checkout before you place your order.

We understand, and it wasn't your fault. This is more than a bottle. You get three formulas, a printed guide for recording your readings, and weekly sessions with Dr. Saunders, so you have a structure to follow and a way to track it.

That's a good question for your doctor, especially if they prefer you add one supplement at a time. We built one complete protocol because the three formulas support different areas of metabolic health. The printed guide and weekly webinars also give you a clear way to follow your progress.

If for any reason this doesn't work for you, or you're simply not happy, just reach out to our customer support team at support@bartonnutrition.com or 888-222-5213 within the 90 day guarantee period. They'll give you a Return Merchandise Authorization (RMA) number and simple instructions for sending all of your bottles back, both empty and full. Once we receive and approve your return, your refund goes back to your original payment method within 7 to 10 business days. The refund is the purchase price, less any shipping and handling fees.
