I've been trying to figure out digestible sources of calcium to recommend to my sister who I found out is only taking in about 200mg of calcium per day. She has a pretty low appetite and I suspect not great gastric acid release, so I worry she isn't even absorbing all of that 200mg.
So I've been researching and experimenting with different sources of calcium. The most promising I've found so far is calcium carbonate dissolved in distilled white vinegar to form calcium acetate. I noticed that it is also used a phosphate binder for people with kidney disorders to block absorption of dietary phosphorous to some degree.

It seems like it could be a good calcium source for people that currently don't have great gastric acid release and also want to increase their calcium to phosphorous ratio to lower PTH. Although some of the calcium isn't absorbed it should help overall to increase the serum ratio.
It doesn't taste great, but if you get the ratio of vinegar to calcium carbonate right it doesn't have a very acidic taste and you can chase it with some juice. I do about 1/4 tsp calcium carbonate powder to 1-2 tablespoons white distilled vinegar, which should be mostly acetic acid. I haven't worked out the exact amount needed to fully react with the calcium carbonate, but the chemical balance equation says you need twice as much acetic acid as calcium carbonate.
CaCO3(s) + 2CH3COOH(aq) → Ca(CH3COO)2(aq) + H2O(l) + CO2(g)
Ca(OH)2(s) + 2CH3COOH(aq) → Ca(CH3COO)2(aq) + 2H2O(l)
Has anyone tried using calcium acetate this way as a calcium supplement? Or familiar with any reasons why it may or may not be suitable as a way to boost metabolism? Some sources caution that soft tissue calcification is possible with calcium acetate, but it seems like it would be pretty safe in combination with a balance of fat soluble vitamins.
