This was JUST posted on my local WAPF group--I think it's relevant!

a woman on the WAP healthy babies group tested her broth for calcium.
below is her post.......
"Since my little baby has been drinking the broth formula in addition
to breast milk for a couple of weeks now, I was interested to find
out how much Calcium/Magnesium exists in it.
I tested my broth using an aquarium water kit. In parallel, my father
took the broth for testing to 2 different labs.
I live in the Netherlands and my father lives in Romania, so we
obviously used different types of chicken and different waters, but
as you will see, the results are strikingly similar.
Both me and my father prepared the broth in the same way: we used all
the bones from one single pasture chicken (aproximately 200g of bones
in total). We cut the bones in pieces as much as we could, covered
them with aprox 2 liters of water, then we added 2 TBS of vinegar
(ACV) and let the bones+water+vinegar stand for 1 hour. Then we
brought the mixture to boil and boiled it on low fire for 24 hours.
With my aquarium kit, I have tested 100mg of Calcium per liter and
150 mg Magnesium per liter.
My father took the broth sample to 2 labs: first, to an industrial
lab, and second, to a food safety lab. The test that came from the
industrial lab gave the same result 100 mg of Calcium per liter.
However, the food safety lab gave a slightly more amount of Calcium
-150 mg of Calcium per liter. The Food safety lab found that in the
broth exists two types of Calcium: the first was in the form of
calcium carbonate ( CaCo3); this calcium was 100mg per liter in the
broth. The second type of calcium was in an ionic form ( Ca++) and
this one was 50mg per liter. Thus, the Total Calcium was estimated to
150mg per liter.
So, my conclusion was that 1 liter of broth made using all the bones
of one pasture chicken( no feet, no head) will probably provide
between 100- 150mg of Calcium per liter."
