Hi, my Vitamin D levels were recently tested and found to be low (29 nmol/L). Based on recommendations from others on this forum, and websites such as grassrootshealth and vitamin D council, I have just started supplementing at 5000 IU per day.
I have read that calcium levels in the blood need to be checked? Is this essential? When should this be done - after 2 to 3 months maybe?
Worried that GP will refuse as they told me to "just take a good multi vitamin", and will likely question why I'm taking such high doses (and maybe tell me to stop!)
This is same GP who prescribed 50 mcg of cyanocobalamin even though my B12 level was 230, so I don't think they know much about supplementing vitamins!
