After spending years directing urinary and salivary hormone testing, analytical chemist Mark Newman set out to combine the best of both worlds with the DUTCH (Dried Urine Test for Comprehensive Hormones).

For the past couple of years, we've been happily using the DUTCH as a tool for improving health and performance in athletes as part of our Elite Performance Program.

In this interview, Mark discusses the recent expansion and improvement of the DUTCH to include the cortisol awakening response (CAR), and several markers related to hormone and neurotransmitter metabolism.

Here's the outline of this interview with Mark Newman:
