Here is a point. those who take prescription drugs, for example: Lipitor places havoc with vitamins. Lipitor can flush out the vitamins, (water solubles)
synthetic hormones, man-made, also play havoc with vitamins, in other words whatever vitamins you take, you get little benefit from.
I think this is very important info to know. What good are vitamins and supplements when other things are going on.
those who have had sterilization, again it causes for an imbalance of hormones in blood stream. So, consider this.
