Can I take 50 and Calcium together?

Why this happens

Calcium carbonate (and other calcium salts) can bind to the levothyroxine in your stomach or intestines. This creates a 'clump' that is too large for your body to absorb into the bloodstream, so the medicine simply passes through your system without working.

You must separate the time you take these two medicines. Take your levothyroxine on an empty stomach, at least 30 to 60 minutes before breakfast. Wait at least 4 hours after taking your levothyroxine before taking any calcium supplements or antacids containing calcium.
