IsoSciences has continued to expand its offering of Vitamin D standards. We have the most complete offering of Vitamin D derivatives on the market and, importantly, IsoSciences is the source manufacturer of all of them.

Some of our vitamin D derivatives are unique to IsoSciences. For example, we are working on a number of 13C labeled vitamin D derivatives for critical applications where deuterium may be problematic. While some molecules, like the side chain labeled 2H6 derivatives, have been on the market for some time and are perfectly suitable for some applications. Our goal is to make all of the options available to you at one location, in one catalog. While stable isotope labeled Vitamin D standards were pioneered by IsoSciences we continue to believe we can earn your business by understanding your application needs and offering the most efficient technical solutions, coupled with the highest quality product.
