 I've had Hashimoto's disease and polycystic ovarian syndrome. I need a progesterone. I was low on progesterone. I needed to take it ten days out of the month. And they were ten very specific days. You couldn't just say on December 20th, on January 20th, every single day of the month you take it. No, you actually have to know the science of your own body to know that you're taking it at the right time is optimal to help support the health of your body. And that is guided by medical physicians.
