How it works

Think of calcium as a structural building block — it supports bone mineralization and density, and also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS].

Safety profile

FDA received 592,059 total adverse event reports across all products. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer, and can cause side effects including constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS] [FDA data].

Our recommendation

You should be aware that calcium can reduce the absorption of certain medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available on a specific dosage for these chews.
