 If you can eat a piece of grass-fed meat and change the color of your urine to a yellow or ideally a green, then you really have a healthy gut and you can extract the nutrients out of that piece of grass-fed meat and the change of the color of your urine, just like you're taking a vitamin supplement. So, doctor, how about you? This sounds weird. Are you able to do that with a piece of grass-fed meat? Yes.
