I've been looking for a supplement with the calcium, magnesium and potassium combination for a while and this combination is often hard to find in stores, even specialty stores and when you can find it, it is crazy expensive. The three work together well. Potassium, apart from acting as an electrolyte, is required for keeping the heart, brain, kidney, muscle tissue, etc. healthy. Magnesium enhances the absorption of calcium which is needed for strong bones, but it also works hand in hand with calcium to support the nervous system. I had been taking another product for hot flashes, and it worked for a while, but I started having hot flashes again after about a year on the other product, and the hot flashes were getting bad. I ran across an article where a doctor observed a reduction in hot flashes when his patients took magnesium (for other reasons). I thought I'd give it a try and was amazed at the results. I had been taking half a dose (1 tablet a day instead of 2) of this product since my diet is already pretty healthy, so I get a lot of vitamins forom my dient already. After reading the article, I went to a full dose daily - 1 tablet in the morning and 1 at night before bed. Hot flashes are GONE!!!

I work construction, bike, hike, and lots of physical activities. My problem was muscle cramps. Sports drinks helped but at night I would get leg cramps. I started taking this supplement and within a few days all my cramps were gone. My life has changed since taking Cal,Mag, potassium. Hope it helps you as much it has helped me.

I have begun using this and MegaFood's' Women's Multivitamin ever since I learned that most mineral-containing supplements (even one I know of which claims to be 'vegan') are made from pulverized rocks, which can damage your digestive tract. I highly recommend you buy minerals made from foods, not rocks.

This product doesn't have carbonate. It it one of the few products out there that does not have carbonate. I have an auto-immune disease and cannot take the other types out there. I was told that carbonate causes heart disease. This one doesn't have that ingrediate and it works for me.

Each pill has 5% of your daily calcium, meaning you need to eat 20 of them to get 100%. The magnesium is slightly better: 15 pills. But get this: you have to eat 100 of them for your potassium. This product is a total ripoff.

I am a real idiot for not reading the reviews and the bottle label before buying this. Each pill contains only 10 %DV of calcium. Which means that I would need to take 10 pills a day. In addition, each pill contains only 1 %DV of potassium, so I would need to take 100 pills a day - can't do that . because each bottle only contains 90 pills. so DO NOT WASTE YOUR MONEY on this product !!!
