Have you ever encountered a situation in which you experienced (or had another person experience) a drug (OTC or prescription), herbal, or supplement-nutrient interaction? If so, explain what it was. If you have not, research a common interaction and explain it. Your explanation should include what drugs, herbs, or supplements and nutrient(s) are involved as well as the possible result of the interaction. Note that you are not to report on the side effects of a drug, herb or supplement, but rather how these might interact with a nutrient (in foods or in supplemental form) and result in a negative effect.
