Which is more effective at raising pH, Tums or baking soda?

Chemical buffers like Tums (calcium carbonate) and bases like baking soda (sodium bicarbonate) are both used medically to reduce acidity in the stomach to ease heartburn symptoms. I'm curious which is more effective in vitro.


I'm interested specifically in the comparison in effectiveness of bases and buffers, which act in slightly different ways to raise pH. I'd also love to learn the math behind figuring this out so next time I can answer such a question myself :)
