Actually all the tablet forms of magnesium are MUCH larger than
the SlowMag. SlowMag only has 64mg in it, which isn't much.

The chelates are all huge. Magnesium malate especially is very large. It has 150mg magnesium and 850mg of malate, and is almost an inch long.

Since you have swallowing problems the liquids or powders (Ionic fizz and Calm) would be best for you.

You can continue with the lotion... it is absorbed. It just does so silently you can't feel anything. I use it before bedtime and it helps me relax too. If you had muscle cramps or other symptoms you'd notice right away. Taking a bath in epsom salts also is effective. 4-6 oz in a tub of lukewarm water.
