I've been hearing a lot lately about getting D3 levels checked and its relation to cardiac health. I haven't tried it yet but I will be asking for it on my next blood work because a friend of mine, who works in health care, strongly suggested to do so.
Your post is about to drop off the front page of this Community, so I reply in part to get more information that may help get a useful response.
What is D3? I understand that if I don't know I am not what your are looking for, still I may benefit (an others too) to have a better idea of what you are taking given the excellent results.
