I'm on the calcium/magnesium powder from Standard Process. One tablespoon a day mixed in something warm and acidic (I do apple juice, one of the few fruit items I do these days). It's about $50 on Amazon and one bottle lasts about a month, or a little more. It's not super cheap, but for the dosage it's better than the pills.
I just sent you a private message. Hoping for your input on something:)
