Every medication has potential side effects. The same holds true for supplements, and even for food. For example, the consumption of peanuts and shellfish can severely harm or kill people whose immune system overreacts due to allergies.  So yes, I’m conscious of the potential side effects of everything I do. To mitigate the risk as much as possible, I listen to my body and frequently get my blood levels checked. If something is off, my doctor and I figure out a way to fix the issue.
