what is Boron ?

How large are these tablets? I have difficulty swallowing large tablets and prefer chewables. Could they be easily broken into small pieces?

What is the difference between this supplement in pink packaging, and the one in purple packaging (https://amzn.to/3hna4js)? they have the same desc.

To those who bought this recently what is the expiration date? Thanks!
