Thomas DeLauer warns daily liver may hinder calcium absorption

What was said

"What they found is that when you have elevated retinol, like too much liver, it actually outco competes vitamin D for the shared receptor. So it reduces calcium absorption. So eating liver every day, can actually be problematic. You can actually mess yourself up."

Thomas DeLauer says research he attributes to the American Journal of Clinical Nutrition links elevated retinol from frequent liver intake to reduced calcium absorption. He argues this could make eating liver every day problematic, and suggests limiting liver to about once or twice weekly and taking vitamin D supplements on non-liver days.
