Doctor's Best Doctor's Best, High Absorption Magnesium, 120 Tablets

Is this magnesium orotate?

The coating disappears rapidly as soon as I put it in my mouth. I've choked on it a few times. Any suggestions for getting this down easier?

How long is each tablet?

How does this type Magnesium compare with the Taurate form? "information overload" online! Just want the best most readily absorbed beneficial! :)
