Vitamin D regulates microbiome-dependent cancer immunity
In humans, low vitamin D levels were correlated with tumor development, and gene signatures of vitamin D activity were associated with improved patient responses to immunotherapy. These findings highlight the connection between vitamin D and the immune system through gut bacteria and may have applications for improving cancer therapies.
This is important - make sure you have your blood tested for vitamin D. If you are below 60 ng/ml (I maintain mine ~70 ng/ml), you are not getting the maximum anti-cancer (including leukemia) benefit.
