I am Dr. Kramer a former FDA consultant and Harvard Medical School faculty member. I have worked in the global pharmaceutical industry for more than 20 years. I am a hyper-expert on drug metabolism and drug interactions.

In this channel I will address food-drug herb-drug and drug-drug interactions. I explain how to avoid them and how they can occur. I assist people to reduce their side effects and live a healthier life. Contact me if you have any questions.
