Effervescent tablets: Any side effects or concerns?

Just be careful with those effervescent calcium tablets.

The body only absorbs about 10% of them.

That means 90% goes to waste. Or, to put it bluntly, most of it just gets flushed out—or worse, ends up as buildup in your kidneys or lining your arteries.

I’ve been sipping on these almost like they’re fruit juice lately... 😳 😬 I used to just stick to getting my Vitamin C from food, but I recently switched over to actual supplements, so I don't really bother with anything else anymore.
