If you use an iron washer, you won't have to ever take an iron pill again. You'll get all the iron out of that washer, probably more and better than an iron pill!
If you use a magnesium washer you can skip that daily vitamin too.
If you use a copper washer, well... skip that vitamin too. You won't need it.
Now, if you use all 3 washers together, you can just skip your one-a-day multi vitamins all together! And probably get better minerals in your system.
Of course... calcium will come from the water itself, if you are not using filtered or distilled water that is.
That's my 2 cents!
Seems funny America has become a nation of pill poppers. We had steel pipes in our home and that was replaced with galvanized. Galvanized was replaced with copper. Copper was replaced with PVC. PVC is replaced with plastic Pex. So we removed all the places we get those vitamins and minerals naturally, and replace that by popping pills. Then we wonder why we get cancer!
