Are VitalPrime supplements safe to take with prescription medications?+
We always recommend consulting your physician before starting any new supplement regimen, especially if you are taking prescription medications. Our formulas are designed with safety in mind, and our medical advisory team is available to answer specific questions.
How long before I see results?+
