Our work is based on government funded research as well, but it's more up-to-date. We work with world leading experts such Dr. Bruce Hollis who has spent more than 40 years researching the appropriate Vitamin D consumption. He's started the Vitamin D council (see link below) to inform people how we as a population should be taking more Vitamin D and in particular Vitamin D3.
