Is there a form of vitamin D that won't give me nausea? I was taking the 3K worth of D that my MD recommended and I started to experience extreme nausea Vitamin D Council
| Hypercalcemia Symptoms (too much vitamin D) • feeling sick or being sick • poor appetite or loss of appetite • feeling very thirsty • passing urine often • constipation or diarrhea • abdominal pain • muscle weakness or pain • feeling confused • feeling tired  | Magnesium Deficiency Symptoms • Irritability or anxiety • Nausea • Headaches • Insomnia • Fatigue • Muscle cramps/twitching • Weakness • Constipation  | 
Notes
- It appears that low Magnesium happens 10X to 100X more often than excess Calcium (Hypercalcemia)
 - Symptoms of low Magnesium can happen in days
 - There appears to be additional, as yet unknown. reasons that ~1% of the population have problems with vitamin D
It might be the form of vitamin D, or what is added - see Low Cost vitamin D - including liquid and bulk
