There appears to be much confusion regarding supplements to avoid during pregnancy and breast feeding. Rightly so, I often here recommendations from “experts” that demonstrate clear lack of understanding in human biochemistry.
Firstly, the distinction of “risk” between a food and a supplement needs to be clarified. That is, the consumption of a naturally occurring compound (present in its natural state) in food as compared to taking an isolated, extract many times greater in concentration than the amount present in the food.
Without giving you an unwanted biochemistry lesson of various biological pathways, I’ll provide some perspective.
