My vitamin D3 topical works well for me. Can I continue to use it?
Because vitamin D3 topicals contain toxic ingredients the length of time the product can be used and the locations where one should use them, are limited. Vitamin D3 preparations, because of the above, are prescription medications, which always and only should be applied under the guidance of a physician.
