I have problems with d3. It makes me sick. I almost black out. I am not on a low carb diet. I have been searching the Internet for answers. I am getting an EEG this week. My dr thinks it could be causing seizures. I can take D2. My blood calcium and magnesium levels are normal. My D levels are low and my Dr said D3 has autoimmune benefits that D2 doesn't.

Magnesium makes me feel worse. Actually supplementing with calcium makes my brain much better. All of these minerals and D are tied together with PTH. Be careful playing with your health based on info from someone selling their latest book.

Ill be back of I figure out what is going on.
