Today from 1-2PM Eastern time, the American Council on Science and Health and the ABC News Medical Unit are teaming up to talk all about Vitamins and Other Supplements.

Using the social media site Twitter, the health groups will be interacting with other doctors, bloggers and patients to answer questions such as:

Do you use supplements to prevent or treat a cold?
What does the science say about Omega-3 fatty acids?
Do dietary supplements help to manage #arthritis? What does the science say?

and more.

The panel will be moderated by Dr. Richard Besser, ABC’s chief health and medical editor. The hashtag will be #abcDRBchat
