<s>[INST] Can you take too much calcium? [/INST] Getting too much calcium from foods is rare. Excess intakes are more likely to be caused by the use of calcium supplements.

High calcium intake can cause constipation. It might also interfere with the absorption of iron and zinc. High intake of calcium from supplements, but not foods, has been associated with increased risk of kidney stones. Some studies also link high calcium intake, particularly from supplements, with increased risk of cardiovascular disease.

It’s best to get your calcium through your diet, rather than supplements. Source: American Bone Health. Link: https://americanbonehealth.org/frequently-asked-questions/. Field: Rheumatology. Disease: Ostoeporosis </s>
