I am a mother now. While I was pregnant, I got a bottle of SeaCal Calcium supplement by ForMor. It is organic calcium. Its recommended dosage is 1 capsule 3x a day for pregnant and lactating women, but if you need more calcium, you can add up to three more without adverse side effects.
SeaCal is not just calcium per se but a combination of ingredients to make calcium absorption in the body more efficient. Anyway, I have a history of kidney stone so I am being careful with my calcium intake. I sometimes drink milk and I sometimes take SeaCal, but I limit it to one a day. But most of the time, I don't take SeaCal, I take it only when I feel pain in my back. I would take it for two days, 1 capsule a day, and after two days, I will really be relieved of my backache. So it means that SeaCal's calcium has maximum absorption in my body.
SeaCal however is more expensive than other brands, probably because of the technology used and of course it is a combination of many other ingredients. But for me, since I take it intermittently, my 1 bottle lasted for six months. SeaCal has very good effect on me, and I would recommend it to anyone, especially those with symptoms of osteoporosis.
And I am confident with taking it because it is made up of organic ingredients.
