Calcium (from Calcium Carbonate) ????

Posted by adhd-researcher on Jun 26, 2016

why they have to add useless Calcium (from Calcium Carbonate) ? carbonate is the worst bio available calcium is it because doctors say you have to take both ? most people have too much free flowing calcium in the body causing aches & pains and should not take any calcium at all and get more magnesium, but this brand might just add some magnesium oxide in some of their products, but the oxide is only good for constipated people

This my 2nd purchase. I like the small dosage because I am testing the optimal level. I am using this to increase my energy level, but most important, I am using D3 to control my eczema. D3 does remove the itchiness but I think I need to take for a couple of weeks/months to totally cure my eczema. Remember to take with magnesium.

The cost-effectiveness of this vitamin, it's great. The product is confiável.É the second time acquire. According to the theory (of course is based on the results of research), vitamin D is inhibitory to most of the ills that affect humans. Only the sun is not sufficient to provide the needs.
