“I’ve been on 16000 IUs (8 little gelcaps) per day for a year. My D level is 104, right at high (not dangerous) level...”
15k IU per day for me, blood level about 90-95 ng/mL. Definitely does lots of good. Google Dr John Cannell or Vitamin D council. He claims 100 to 130 is a great range. Be sure to take it with synergistic nutrients such as vit K2-mk7 and magnesium.
Best to consult a health professional who really understands nutrients and is willing to collaborate on health
Yes, I also take 200 mg with food of vitamin K2.
Other benefits: reduction in age related joint pain, exercise stamina and incredibly, regaining height shrinkage.
