So a recent blood test showed i have Vitamin d levels < 5ng/ml (Essential unreadable) I have been Prescribed Vitamin D 20,000iu supplements to take once a week.
I was wondering if this amount and once weekely disage is enough to treat what woudl see to be a severe deficiency ?
Should i also be taking a magnesium supplement? I have 500mg Magnesium Bisglycinate supplements, should i take one of these daily?
Any advice is greatly appreciated! :)
