By the end of Oct 2020, FDA issued 123 first-time warning letters this year to dietary supplement companies regarding unapproved and misbranded products related to covid19. Those products are herbal products and hemp products marketed online and on social media networks.

Warning letters require producers and marketing companies to take action to correct errors within 48 hours and provide plans to ensure no further violation. FDA takes different actions on repeated errors.

Some dietary supplements are herbal products and some are hemp products.
