I wasn't always taking them, but was recommended to. I had VSG surgery in 2012 which isn't as bad as bypass but still has malabsorption of nutrients. D is my biggest difficiency. I've been taking D3(5000iu)+k2 since March religiously, and recently added 50mg zinc, and I ran out of vyvanse and a little weary of going back to dr just for a refill, so have been using caffeine + l-theanine which helps some... I also take magnesium/calcium before bed as I heard you're supposed to take those when taking D3.
