Difference between Vitamin D an Vitamin D3
Any difference to these two types of Vitamin D?
My family doctor found out my Vitamin D level is very low; I started to take Vitamin D3 for 2000iu per day, as instructed by my doctor; I then started to notice I have swollen gums and redness... am I taking too much?
Should I take Vitamin D after meals or any time preference??
Appreciate your advice:
