Everything in Moderation imo. If you're healthy doing what you're doing why switch?
I feel they do this for a period of time, for so many different supplements.... "Everyone, you MUST TAKE VITAMIN A, its the best thing for you ever!!! A few months later, DON'T TAKE VITAMIN A it kills you!" Looking back in time, they have done this for so many different things over and over, it's hilarious.
But thanks for sharing!
