As a responsible supplement company we always recommend to consult with your doctor first before taking our products as we are not able as well as not allowed to give you any medical advice. Also any interactions with your current medication has to be moderated by a board-certified physician who knows exactly your treatment regimen.
Of course, our products shouldn't harm you in any ways.
Regarding Astaxanthin (an ingredient in our Collagen Activator) and drug interactions I would like to recommend the literature of the following paper: https://www.naturalmedicinejournal.com/journal/astaxanthin-review-literature (scroll down).
Also https://www.webmd.com/ is helpful to search for nutrient-drug interactions.
