b.Pick an FDA warning letter related to a Dietary Supplement Company and attach the link to your homework.
c.Describe, in your own words, why the organization received the warning letter, and what could have been done to prevent this quality issue. You may need to do some research on the federal code of regulations 21.CFR.111 to understand what the issues in quality were, and what they could have done to mitigate/prevent the occurrence of the issue.
