This webinar consists of a 24-minute presentation by Dr. Hollis, followed by 15 minutes of questions and answers. Hollis thoroughly explains how vitamin D supplementation is processed by both the endocrine and autocrine systems. He reviews clinical trials that have had success or failure and correlates their results with their dosing strategy. It is a very technical presentation, but if you don’t yet understand why daily dosing is important, then please watch this webinar so that you can fully understand the importance of daily dosing.
