I like it but I would like to have measurement spoon to be sure how much I take. That's a single negative thing that there's no spoon in the bottle.

Thanks for your feedback!

I can't be positive, but so far it seems like I am having fewer muscle cramps.

.I know it's usually magnesium that is the cramping problem, but I couldn't solve this issue, until switching to this calcium . I also recently added in potassium drops, so who knows for sure, but maybe I absorb this powder better for some reason, than the capsules I was using. It's easy enuf to stir it into my water everyday.

Thanks for your feedback!

Is it really eco-friedly?

This Calcium has good-quality, but why I see the * (star) after eco-friendly tale? CORALS ARE GROWING FOR YEARS, they ARE LIVING BEING and are nesessery for the world ocean! I DON'T WANT ANY SINGLE CORAL TO DIE FOR MY BOTTLE OF SUPPLEMENT! Humans, you need to think not only about yourself, about nature, too. We need the proof this calcium is really eco-friendly!

Thanks for your feedback!

I liked the powder form. I take equal amounts of calcium and magnesium. Works for me.

Thanks for your feedback!

Alkaline perfection - addition to my almost vegan (vegetarian) diet, because I need more calcium and magnesium than food can offer me. I am living in huge stress conditions for couple of years and I am also an athlete, so I must take care of myself. You can also try it, because it is one of the best formula here in iherb. No nasty ingredients like are in other formulas with colorants, stearates, etc.
