160: Supplement Timing and Food Combining for Zinc?

Masterjohn Q&A Files Episode 160


Question: Supplement Timing and Food Combining for Zinc?

So for zinc and food, the main issue is that, my guess is that a carnivore meat based meal would probably enhance zinc absorption, but that's never really been tested. There's some controversy in the field over whether you should take zinc on an empty stomach or not. So my position is basically like if it's practical for me to take the zinc on an empty stomach, do an empty stomach. And if it's not practical for you to take the zinc on an empty stomach, do it on a phytate free meal - no whole grains, nuts seeds or legumes.
