Added to what? 

[TheVat]

To your stomach?  Sounds like an antacid blend.  The baking soda part (NaHCO3) part will react pretty quickly with the stomach acid (HCl).   The calcium carbonate will also neutralize the acid.  Not sure but I think the baking soda works a little quicker.  

Both lower the concentration of H+ radicals.

IN water

what happens if you add calcium carbonate and sodium bicarbonate in water?
Does a reaction occur?

[TheVat]

Why don't you try that, then?  Being mindful what a basic antacid does, perhaps you can hypothesize what the result will be.  Grind up some eggshells (or use powdered garden lime) in water, add some baking soda, see what if anything happens.   You are the observer 1, right?

thought that i could get the answer without doing it tho.
but anyways i will do it

RESULT:- LITERALLY NO REACTION

Yes, since bicarbonate and carbonate are essentially the same system, the only reaction you might get would be a displacement of ions if a new compound could form that was less soluble the they are and would preferentially precipitate out. But calcium carbonate is much less soluble than sodium bicarbonate, so you won't get many carbonate ions. Sodium carbonate is more soluble than either, and calcium bicarbonate does not form in the solid state at all.

when calcium carbonate (caco3) and sodium bicarbonate NaHCO3 are added to each other a reaction does occurs which producs sodium carbonate Na2CO3 and calcium hydrogen carbonate (ca(hco3)2). in this reaction the sodium bicarbonate and calcium carbonate acts as an acid or base which reacts to form salt and water also releasing carbon dioxide as a byproduct. the reaction is endothermic or generates heat.

No, an endothermic reaction absorbs heat. 

The rest of your post doesn't seem to make sense

Why would you post that in a thread where someone has actually done the experiment and told you that there is

" LITERALLY NO REACTION"?

Good you have shown it for yourself as should observers.

 

You may wish to get more out of this question by investigating the bicarbonate buffer.

The bicarbonate buffer plays an hugely important role in life science, climate science, oceanography and other places.
