Can I take QD1 with my current treatment or medication?

Our products are compatible with many medications for gastrointestinal conditions. In order to determine the most suitable product for your specific needs, please take our online assessment where we ask about your medication and background. This helps us ensure the compatibility of our products with your current situation.

How do you know what supplements I need?

We’ve conducted extensive research, and base our strategies on data gathered from multiple patients–in our clinics and labs. We’re constantly refining our research with vital information from our users and customers on their pre-existing conditions, gut symptoms, and test improvements.

What if I miss a dose?

If you’ve missed a single dose, simply continue with your regular plan. If you’ve missed a daily dose or more, please contact us and we’ll be in touch shortly.

How many supplements can I take at one time?

We recommend a limit of 3-4 supplements at a time. Taking too many supplements at once makes it difficult to follow up on your response to specific remedies. The supplement bundles in your recovery kit will provide all the support you need, while still allowing us to track your progress.
