It depends on the quality of ingredients and the formulation...
According to the book Over-the-Counter Natural Cures: ”Synthetic Vitamin D, including your prescription vitamin D, increases diseases by 32% including heart attacks because Synthetic Vitamin D is unrecognized by the body and deposits calcium into the heart tissues, but not to the bone"!!!Dr. Russell Jaffe says:
But Vitamin D by itself is not enough to perform the right tasks without harming the body...
"Vitamin D goes into more than 2000 Genes" as Dr. Bruce Ames wrote in his research paper.
Also, Dr. Kate Rheaume-Blue discovered in her research paper that: “ You must include K2 (full spectrum MK7) most active form to Help direct Calcium deposits into the Bones and Out of the Heart Arteries.”
