I realised that I'd been taking too much liquid D3 recently, I'd been taking 3000 iu daily and then I also spilt half the bottle on my arm when I was studying the dose.
I've been getting bad bone aches in my knees, fingers, wrists and back since supplementing with it.
As too little vitamin D can lead to osteopenia, so too can excess.
When there is too much it leaches calcium through bone resorption.
