metallic taste in mouth after taking calcium

I have read about the metallic taste in the mouth and ketosis, but I have only seem to experience the metallic taste after I take my calcium supplements. Is this still ketosis or something else?

What type of calcium are you taking?  Perhaps it's a binding agent in whatever type you're taking?

It's Calcium Citrate with vitamin D from Trader Joe's. The other ingredients listes are cellulose, polyethylene glycol, magnesium stearate (vegetable source), cellulose gum and titanium dioxide.
Also, Andrea, since you seem to know a lot about vitamins. Is it okay to crush the calcium tablets?

I taste that metallic taste even with tums. It would be interesting to find out why.

I hope you aren't taking Tums for your calcium source -- it's calcium carbonate, which is not bioavailable in RNY guts.

Well, some vitamin D3 concoctions can cause metallic taste in the mouth.  And hey, perhaps you are sensitive to one of the binding agents.  I would try another brand with slightly different ingredients and check and see -- maybe citracal -- if you have the same reaction.

And yes, crushing the calcium is fine.  I know that citracal dissolves easily into crystal light without changing the flavor -- you might try that with the TJ stuff.
