I am hypocalcimic & must make sure that I get my full daily quota of calcium. Unfortunately, most calcium products don't digest well in my system plus because I take an prescription D I have to have a calcium product without D. I have found Source Naturals Amino Acid Chelate Calcium the best of all the calciums I have tried. When using Source Naturals Amino Acid Chelate Calcium my blood levels of calcium are always in the normal range. When using any other calcium product, my blood level calcium drops below normal. So now this is the only calcium I will use.

I took this for about 2 years. Not strictly every single day but most days. After pain in my left side for a few weeks, then pain in my bladder for a week; I passed several tiny stones. Got an ultrasound on my kidneys and have one small stone left. I eat clean and don't take drugs of any kind. I have no diseases either. I will not take this kind of calcium again.

For my calcium intake.

well absorbed

This works well for me

Been taking this for about six weeks. Energy is more consistent and I feel less sluggish in the afternoons. Happy with the purchase.
