@sandyjr Your daughter has a complicating condition with Crohn's, so she needs to talk to her doctors about which calcium supplement is safest for her, given her medical history and current medications. Also the best time to take it so it doesn't interfere with other meds. She also likely has poor absorption in her intestines, which will also need to be considered.

The only ones I can take are from algae, Algaecal for example but there are others in the drug store. (Garden of Life and Alive). However just had normal stomach issues from the regular calcium (always wonder if I knew about Algaecal 20 years ago maybe I wouldn't even have gotten osteoporosis). I agree with the person who said your daughter may have absorption issues so she should have that checked out.

So, what should i take? I walked for one hour everyday alone abd it is fine,🥰but when i go out, my walking is not consistent

Is algae safe to take ..I just wonder if it really safe for consumption..they can put anything on a bottle ..

I take New Chapter Bone Strength which has calcium that's sourced from algae. The pills also include vitamins D, K1, K2 and Magnesium. Note, the pills don't actually contain algae, instead the calcium is harvested from algea because it's naturally high in calcium. I buy them on Amazon.

I make my own calcium from eggshells. I only use local pastured antibiotic free and soy free eggs. I bake the shells at 250 for 1 hour. Cool then grind them in my coffee grinder to a fine powder. 1/2 tsp everyday mixed into my Greek yogurt.
