How long after taking a set dose do you guys get blood work? It takes a couple months to stabilize I think.
I did feel better when I was taking 2000IU though, I think I will come back lowish in range even though its summer here now, if I do I will probably bump it up to 3000IU per day.
BTW its a good idea to take calcium with vitamin D.
The relationship isnt so simple between calcium and vitamin D, but if you are taking vit D you need to take calcium aswell if your not getting enough from your diet.
