What is the ratio of ca to mg to na in this formula?

Good question. Thanks for asking. The ratio (by weight) is 70% magnesium, and 17% calcium, and 13% sodium. (mostly from sodium bicarbonate, and a very small amount from sodium chloride.)

How long is the product good for? Does it have an expiration date?

There's no expiration date on the package. I wasn't expecting to find one because minerals are pretty stable, just keep them dry.

Is this for use in espresso machines or just drip type coffee?

The minerals are balanced to be safe for use in espresso machines.

Can I use this with the filter that is in the coffee machine's tank?

Yes, it is completely safe and will not affect the filter in the coffee maker.
