I have had my vitamin D25 OH level checked regularly for over 3 years due to severe osteoporosis treatment. After I switched to this as my main source of D3, my blood level of D25 OH dropped unexpectedly. I do not trust this product and wish I had not been using it for over half a year. Brands I trust based on testing are Now and Life Extension.
